Description

Technical Field

[0001] This utility model relates to the field of metal processing machinery manufacturing, and in particular to a connecting device and machining equipment. Background Technology

[0002] In related technologies, machining equipment may include interchangeable machining platforms. These platforms are detachable to be used with different types of machining equipment (such as EDM equipment, CNC machining equipment, etc.). Currently, machining equipment typically achieves detachability of the machining platform through a pneumatic locking mechanism. However, this pneumatic locking mechanism requires a continuous supply of high-pressure gas to lock the machining platform, resulting in high costs. Utility Model Content

[0003] This utility model provides a connecting device and machining equipment to solve at least one of the above-mentioned technical problems.

[0004] This utility model provides a connecting device for use in machining equipment, the connecting device comprising:

[0005] A connecting mechanism, comprising a first connecting seat and a second connecting seat used in conjunction with the first connecting seat, the first connecting seat being used to connect a processing platform, the second connecting seat being used to connect a base plate, one of the first connecting seat and the second connecting seat being provided with a slot, and the other being provided with a locking block;

[0006] A switching mechanism includes an operating element, a magnetic component, and an elastic element, the elastic element being connected to the card block, and the operating element having a locked position and an unlocked position and being able to switch between the locked position and the unlocked position;

[0007] In the locked position, the operating member provides magnetic force to the card block through the magnetic component, causing the card block to engage in the card slot and compressing the elastic member, thereby locking the first connecting seat and the second connecting seat. In the unlocked position, the operating member resets the elastic member to disengage the card block from the card slot, thereby unlocking the first connecting seat and the second connecting seat.

[0008] In the aforementioned connection device, the switching mechanism can switch the position of the operating element, use the magnetic component to provide magnetic force to the card block, and use the elastic element to reset, so that the card block engages and disengages from the card slot, thereby putting the first connecting seat and the second connecting seat into locked and unlocked states, realizing the engagement and disengagement of the processing platform and the base plate. Compared with the method of continuously using high-pressure gas to lock the processing platform, it reduces the cost of use to a certain extent.

[0009] In some embodiments, the magnetic component includes a first magnetic element, a magnetic block, a second magnetic element, and a connector. The first magnetic element is disposed on the connector, and the connector is connected to the card block. The second magnetic element is disposed on the operating element, and the operating element is provided with a magnetic suction element.

[0010] When the operating member is in the locked position, the second magnetic member and the magnetic block generate a magnetic repulsion force, causing the magnetic block to be in a first position that can provide the magnetic force to the first magnetic member.

[0011] When the operating member is in the unlocked position, the magnetic attractor and the magnetic block generate a magnetic attraction force, causing the magnetic block to be in a second position where no magnetic force is provided to the first magnetic member, or the provided magnetic force is less than the elastic force when the elastic member is reset.

[0012] In the above-mentioned connecting device, the interaction between the operating component, the magnetic component, and the elastic component can realize the switching between the engaged state and the disengaged state of the card block and the card slot.

[0013] In some embodiments, the magnetic block includes a protective element, a third magnetic element, and a fourth magnetic element, wherein the third magnetic element and the fourth magnetic element are spaced apart within the protective element;

[0014] When the magnetic block is in the first position, the third magnetic element and the second magnetic element generate a magnetic repulsive force, and the fourth magnetic element and the first magnetic element generate a repulsive magnetic force.

[0015] When the magnetic block is in the second position, the third magnetic element and the magnetic attracting element generate a magnetic attraction force, and the fourth magnetic element does not generate the magnetic force with the first magnetic element or the generated magnetic force is less than the elastic force when the elastic element is reset.

[0016] In the above-mentioned connecting device, the position of the magnetic block can be controlled by the magnetic force between the first magnetic component, the second magnetic component, the third magnetic component, and the fourth magnetic component, thereby realizing the switching between the engaging and disengaging states of the card block and the card slot.

[0017] In some embodiments, the connecting mechanism further includes a contact member for connecting to the processing platform. The contact member is in contact with the protective member. When the magnetic block moves between the first position and the second position, the protective member and the contact member move relative to each other. The contact member is used to reduce the frictional force on the protective member.

[0018] The aforementioned connecting device allows the magnetic block to move smoothly, thereby improving the working efficiency of the connecting device to a certain extent.

[0019] In some embodiments, the protective element is a glass fiber protective element, and the contact element is a glass fiber contact element.

[0020] The aforementioned connecting device extends the service life of the protective components and contact components to a certain extent.

[0021] In some embodiments, the connector includes a pushing part, the coupling device includes a resetting part, and the elastic element is connected to the locking block via the pushing part;

[0022] When the operating member is locked, the pushing part abuts against the locking block to cause the locking block to engage in the locking slot and to compress the reset member.

[0023] When the operating component is unlocked, the elastic element resets to drive the pushing part to move away from the card block, thereby driving the card block to disengage from the card slot when the reset component is reset.

[0024] In the above-mentioned connecting device, the engagement and disengagement of the locking block and the locking slot can be achieved through the mutual cooperation between the elastic element, the pushing part and the resetting part.

[0025] In some embodiments, the pushing part includes a first inclined surface, and the locking block includes a second inclined surface;

[0026] During the process of the operating component moving from the locked position to the unlocked position, the first inclined surface and the second inclined surface cooperate with each other to cause the card block to disengage from the card slot under the action of the reset component;

[0027] During the movement of the operating component from the unlocked position to the locked position, the first inclined surface and the second inclined surface come into contact with each other, causing the card block to be engaged in the card slot under the action of the pushing part.

[0028] In the above-mentioned connecting device, the movement of the pushing part and the locking block is made more stable by the cooperation of the first inclined surface and the second inclined surface.

[0029] In some embodiments, a locking block, a reset member, and a locking groove are provided on each side perpendicular to the direction of movement of the pushing part. The connecting device further includes a connecting rod, which is fixed to the second connecting seat. The two reset members and the two locking blocks are movably sleeved on the connecting rod.

[0030] In the above-mentioned connecting device, the guide action of the connecting rod can prevent the locking block from shifting or jamming, while the reset component can apply an elastic force to the locking block to achieve the separation of the locking block from the slot.

[0031] In some embodiments, one of the first connector and the second connector is provided with a receiving cavity, and the other includes an insertion part inserted into the receiving cavity, and the slot is provided on the side wall of the receiving cavity.

[0032] In the above-mentioned connecting device, on the one hand, the cooperation between the insertion part and the receiving cavity makes it easy to assemble the first connecting seat and the second connecting seat; on the other hand, the multi-directional limiting can, to a certain extent, ensure that the connecting seat and the connecting seat achieve precise positioning and stable connection in three-dimensional space, thereby improving the stability of the connecting device to a certain extent.

[0033] This utility model provides a machining equipment, which includes the connecting device, machining platform and base plate described in any of the above embodiments;

[0034] The first connecting seat is connected to the processing platform, and the second connecting seat is connected to the base plate.

[0035] In the aforementioned machining equipment, the switching mechanism can switch the position of the operating component, use the magnetic component to provide magnetic force to the card block and use the elastic component to provide elastic force to the card block, so that the card block engages and disengages from the card slot, thereby putting the first connecting seat and the second connecting seat into locked and unlocked states, realizing the engagement and disengagement of the machining platform and the base plate. Compared with the method of continuously using high-pressure gas to lock the machining platform, it reduces the cost of use to a certain extent.

[0051] Please see Figures 1 to 4 This utility model provides a connecting device 200 for use in a machining equipment 1000. The connecting device 200 includes a connecting mechanism 20 and a switching mechanism 40. The connecting mechanism 20 includes a first connecting seat 21 and a second connecting seat 23 that cooperates with the first connecting seat 21. The first connecting seat 21 is used to connect to the machining platform 100, and the second connecting seat 23 is used to connect to the base plate 300. One of the first connecting seat 21 and the second connecting seat 23 is provided with a slot 212, and the other is provided with a locking block 232. The switching mechanism 40 includes an operating member 41, a magnetic component 43, and an elastic member 49. The elastic member 49 is connected to the locking block 232. The operating member 41 has a locked position and an unlocked position and can switch between the locked position and the unlocked position.

[0052] When locked, the operating member 41 provides magnetic force to the card block 232 through the magnetic component 43, causing the card block 232 to be engaged in the card slot 212 and compressing the elastic member 49, thereby locking the first connecting seat 21 and the second connecting seat 23. When unlocked, the magnetic component 43 no longer provides magnetic force to the card block 232, and the operating member 41 resets the elastic member 49 to disengage the card block 232 from the card slot 212, thereby unlocking the first connecting seat 21 and the second connecting seat 23.

[0053] In the aforementioned connecting device 200, the switching mechanism 40 can be switched by the position of the operating member 41, using the magnetic component 43 to provide magnetic force to the card block 232 and using the elastic member 49 to reset, so that the card block 232 engages and disengages from the card slot 212, thereby putting the first connecting seat 21 and the second connecting seat 23 into locked and unlocked states, realizing the connection and separation of the processing platform 100 and the base plate 300. Compared with the method of continuously using high-pressure gas to lock the processing platform 100, the cost of use is reduced to a certain extent.

[0054] Specifically, machining equipment 1000 is an industrial device used to process raw materials through operations including but not limited to electrical discharge machining, laser cutting, cutting, grinding, stamping, and forging to obtain parts or components that meet design requirements. Optionally, machining equipment 1000 includes, but is not limited to, equipment such as electrical discharge machining equipment and CNC machining equipment (computer numerical control equipment). Please refer to... Figure 1 The machining equipment 1000 includes a machining platform 100 and a base plate 300. The machining platform 100 is detachably connected to the base plate 300 via a connecting device 200. The base plate 300 is used to support the machining platform 100 and provide mechanical support for the machining platform 100. The machining platform 100 is used to support the workpiece that needs to be machined, thereby determining the position of the workpiece and fixing the workpiece for machining operations.

[0055] In related technologies, interchangeable machining platforms for machining equipment are widely used. Interchangeable machining platforms can be quickly assembled and disassembled through standardized interface design to seamlessly adapt to different types of machining equipment (such as spark discharge machining equipment and CNC machining equipment), thereby meeting the needs of multi-process integrated machining.

[0056] Currently, pneumatic locking mechanisms are commonly used in machining equipment to achieve detachable connections for interchangeable machining platforms. When the machining platform needs to be mounted on the base plate of the machining equipment, the pneumatic locking mechanism uses high-pressure gas to drive a cylinder piston, pushing a locking pin or wedge into a positioning groove within the machining platform to form a mechanical interlock, thereby locking the machining platform to the base plate of the machining equipment. However, because the pneumatic locking mechanism requires a continuous supply of high-pressure gas during the locking process, the large demand for high-pressure gas and the long-term high-load operation of the air compressor in the pneumatic locking mechanism result in high long-term operating costs.

[0057] In this embodiment of the utility model, please refer to Figure 1 and Figure 2 The machining equipment 1000 includes a connecting device 200 for connecting a base plate 300 and a machining platform 100. The connecting device 200 includes a connecting mechanism 20, which includes a first connecting seat 21 and a second connecting seat 23 that cooperates with the first connecting seat 21. The first connecting seat 21 is used to connect the machining platform 100, and the second connecting seat 23 is used to connect the base plate 300. Optionally, the first connecting seat 21 and the second connecting seat 23 are nested together, thereby connecting the machining platform 100 and the base plate 300 through the first connecting seat 21 and the second connecting seat 23.

[0058] One of the first connecting seat 21 and the second connecting seat 23 is provided with a slot 212, and the other is provided with a locking block 232. Figures 2 to 4 In one embodiment, the first connecting seat 21 is provided with a slot 212, and the second connecting seat 23 is provided with a locking block 232 that matches the slot 212. It is understood that in other embodiments, the second connecting seat 23 may have a slot 212, and the first connecting seat 21 may have a locking block 232 that matches the slot 212. When the locking block 232 is engaged in the slot 212, the first connecting seat 21 and the second connecting seat 23 are locked, preventing relative movement between the processing platform 100 and the base plate 300. This ensures that the processing platform 100 is securely locked onto the base plate 300, guaranteeing the accuracy and safety of the machining process.

[0059] Please combine Figure 2 The machining equipment 1000 also includes a switching mechanism 40, which is connected to the locking block 232. The switching mechanism 40 is used to drive the locking block 232 to move so that the locking block 232 engages and disengages from the locking slot 212. The switching mechanism 40 includes an operating member 41, a magnetic component 43, and an elastic member 49. The elastic member 49 is connected to the locking block 232, and the operating member 41 has a locked position and an unlocked position.

[0060] In one embodiment, when the operating member 41 is in the locked position, the operating member 41 provides magnetic force to the locking block 232 through the magnetic component 43. The magnetic force drives the locking block 232 to move and engage in the slot 212, thereby locking the first connecting seat 21 and the second connecting seat 23, so that the processing platform 100 can be firmly locked onto the base plate 300. Since the magnetic force is greater than the elastic force, the elastic member 49 can be compressed.

[0061] In one embodiment, when the operating member 41 is in the unlocked position, the elastic member 49 extends from the compressed state, thereby causing the locking block 232 to move away from the locking slot 212, thereby unlocking the first connecting seat 21 and the second connecting seat 23, separating the processing platform 100 with the first connecting seat 21 from the second connecting seat 23, and removing the processing platform 100 from the base plate 300 for replacement or maintenance.

[0062] Optionally, the magnetic force can be either magnetic repulsion or magnetic attraction. In specific applications, the choice between magnetic repulsion and magnetic attraction is based on actual needs. This is common knowledge to those skilled in the art and will not be elaborated upon here.

[0063] The operating element 41 can switch between a locked position and an unlocked position. Optionally, please combine with... Figure 4 The operating element 41 includes a handle that can be rotated under external force to switch the current position state, thereby switching the operating element 41 between a locked position and an unlocked position. When the operating element 41 is in a horizontal state, the operating element 41 is in the locked position, such as... Figures 2 to 4 As shown; when the operating element 41 is rotated to the vertical state, that is, when the operating element 41 is in the unlocked position.

[0064] Therefore, the connecting device 200 of this embodiment can achieve automatic mechanical elastic locking when the processing platform 100 is installed on the base plate 300. Compared with the method of continuously using high-pressure gas to lock the processing platform 100, the connecting device 200 of this embodiment does not require a large amount of high-pressure gas or the high load of the air compressor. It only uses the operating element 41, the magnetic component 43, the elastic element 49, and a simple locking block 232 and slot 212 structure, which can reduce the cost of use to a certain extent.

[0065] Optionally, the operating component 41 and the processing platform 100 can be made of aluminum. The aluminum does not interact with the magnetic component 43, thus not affecting the normal operation of the magnetic component 43.

[0066] Optionally, the elastic element 49 may be a spring.

[0067] In this embodiment, the magnetic component 43 includes a first magnetic element 432, a magnetic block 436, a second magnetic element 434, and a connector 47. The first magnetic element 432 is disposed on the connector 47, and the connector 47 is connected to the card block 232. The second magnetic element 434 is disposed on the operating component 41, and the operating component 41 is provided with a magnetic suction element 45.

[0068] When the operating member 41 is in the locked position, the second magnetic member 434 and the magnetic block 436 generate a magnetic repulsion force, causing the magnetic block 436 to be in a first position that can provide magnetic force to the first magnetic member 432.

[0069] When the operating member 41 is in the unlocked position, the magnetic member 45 and the magnetic block 436 generate a magnetic attraction force, causing the magnetic block 436 to be in a second position where no magnetic force is provided to the first magnetic member 432, or the provided magnetic force is less than the elastic force when the elastic member 49 is reset.

[0070] Thus, the interaction between the operating element 41, the magnetic component 43, and the elastic element 49 can be used to switch the engagement and disengagement states of the card block 232 and the card slot 212.

[0071] Specifically, please combine Figure 4 The first magnetic element 432 of the magnetic assembly 43 is located at one end of the connector 47 near the processing platform 100, the second magnetic element 434 is located on the side of the operating member 41 near the connector 47, and the magnetic block 436 is located between the first magnetic element 432 and the second magnetic element 434. The operating member 41 is also provided with a magnetic suction element 45.

[0072] In one embodiment, when the operating member 41 is in the locked position, the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436 is greater than the magnetic attraction force of the magnetic member 45 on the magnetic block 436, thus the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436 plays a dominant role. The magnetic repulsion force generated by the second magnetic member 434 on the magnetic block 436 can drive the magnetic block 436 to move away from the operating member 41 to a first position. In the first position, the magnetic block 436 can provide magnetic force to the first magnetic member 432. Optionally, the magnetic force provided to the first magnetic member 432 is a magnetic repulsion force. At this time, the magnetic force drives the first magnetic member 432 away from the magnetic block 436, causing the connecting member 47 to drive the locking block 232 to move and lock into the slot 212, thereby locking the first connecting seat 21 and the second connecting seat 23, and thus the processing platform 100 can be firmly locked on the base plate 300. Since the magnetic force is greater than the elastic force, the elastic member 49 can be compressed.

[0073] In one embodiment, when the operating member 41 is in the unlocked position, the magnetic attraction force of the magnetic member 45 on the magnetic block 436 is greater than the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436, thus the magnetic attraction force of the magnetic member 45 on the magnetic block 436 is dominant. The magnetic attraction force generated by the magnetic member 45 on the magnetic block 436 can drive the magnetic block 436 to move towards the operating member 41 to the second position. In the second position, the magnetic block 436 does not provide magnetic force to the first magnetic member 432, or the provided magnetic force is less than the elastic force of the elastic member 49 when it is reset. At this time, the elastic member 49 extends from the compressed state, causing the locking block 232 to move to disengage from the locking slot 212, thereby unlocking the first connecting seat 21 and the second connecting seat 23, and then the processing platform 100 can be removed from the base plate 300 for replacement or maintenance.

[0074] Therefore, by changing the position of the operating member 41, the position of the magnetic block 436 can be controlled by the magnetic force between the second magnetic member 434, the magnetic suction member 45 and the magnetic block 436, thereby controlling the magnetic force between the first magnetic member 432 and the magnetic block 436, and by using the reset of the elastic member 49, the engagement and disengagement states of the card block 232 and the card slot 212 can be switched.

[0075] Optionally, the magnetic component can be a magnet, and the magnetic suction component 45 can be an iron plate.

[0076] In some embodiments, the magnetic block 436 includes a protective member 436a, a third magnetic member 436b, and a fourth magnetic member 436c, with the third magnetic member 436b and the fourth magnetic member 436c spaced apart within the protective member 436a.

[0077] When the magnetic block 436 is in the first position, the third magnetic element 436b and the second magnetic element 434 generate a magnetic repulsive force, and the fourth magnetic element 436c and the first magnetic element 432 generate a repulsive magnetic force.

[0078] When the magnetic block 436 is in the second position, the third magnetic element 436b and the magnetic suction element 45 generate a magnetic attraction force, and the fourth magnetic element 436c does not generate a magnetic force with the first magnetic element 432 or the generated magnetic force is less than the elastic force of the elastic element 49 when it is reset.

[0079] Thus, the position of the magnetic block 436 can be controlled by the magnetic force between the first magnetic element 432, the second magnetic element 434, the third magnetic element 436b, and the fourth magnetic element 436c, thereby achieving the switching between the engaged and disengaged states of the card block 232 and the card slot 212.

[0080] Specifically, please combine Figure 4The third magnetic element 436b is disposed within the protective element 436a on the side near the second magnetic element 434 and the magnetic attracting element 45, and the fourth magnetic element 436c is disposed within the protective element 436a on the side near the first magnetic element 432. The third magnetic element 436b and the fourth magnetic element 436c are spaced apart. Optionally, the third magnetic element 436b and the second magnetic element 434 are arranged with the same polarity facing each other, and the first magnetic element 432 and the fourth magnetic element 436c are arranged with the same polarity facing each other, so that the fourth magnetic element 436c provides a repulsive magnetic force (i.e., magnetic repulsion) to the first magnetic element 432.

[0081] In one embodiment, when the operating member 41 is in the locked position, the magnetic repulsion force of the second magnetic member 434 on the third magnetic member 436b is greater than the magnetic attraction force of the magnetic member 45 on the third magnetic member 436b, thus the magnetic repulsion force of the second magnetic member 434 on the third magnetic member 436b dominates. The magnetic repulsion force generated by the second magnetic member 434 on the third magnetic member 436b can drive the third magnetic member 436b to move away from the operating member 41 and drive the fourth magnetic member 436c to move towards the first magnetic member 432. At this time, the magnetic block 436 is in the first position, and the fourth magnetic member 436c provides a repulsive magnetic force to the first magnetic member 432. At this time, the magnetic force provided by the fourth magnetic member 436c drives the first magnetic member 432 to move away from the fourth magnetic member 436c, so that the connecting member 47 drives the locking block 232 to move and lock into the slot 212, thereby locking the first connecting seat 21 and the second connecting seat 23, and thus the processing platform 100 can be firmly locked on the base plate 300. Since the magnetic force is greater than the elastic force, the elastic element 49 can be compressed.

[0082] In one embodiment, when the operating member 41 is in the unlocked position, the magnetic attraction force of the magnetic member 45 on the third magnetic member 436b is greater than the magnetic repulsion force of the second magnetic member 434 on the third magnetic member 436b, thus the magnetic attraction force of the magnetic member 45 on the third magnetic member 436b is dominant. The magnetic attraction force generated by the magnetic member 45 on the third magnetic member 436b can drive the third magnetic member 436b to move closer to the operating member 41 and drive the fourth magnetic member 436c to move away from the first magnetic member 432. At this time, the magnetic block 436 is in the second position, and the fourth magnetic member 436c does not provide magnetic force to the first magnetic member 432, or the provided magnetic force is less than the elastic force of the elastic member 49 when it is reset. At this time, the elastic member 49 extends from the compressed state, causing the locking block 232 to move to disengage from the locking slot 212, thereby unlocking the first connecting seat 21 and the second connecting seat 23, and then removing the processing platform 100 from the base plate 300 for replacement or maintenance.

[0083] The protective component 436a can protect the third magnetic component 436b and the fourth magnetic component 436c, preventing the magnetic block 436 from causing wear to the third magnetic component 436b and the fourth magnetic component 436c during movement, which would result in a reduction or loss of magnetic force.

[0084] In some embodiments, the connecting mechanism 20 further includes a contact 25 for connecting to the processing platform 100. The contact 25 is in contact with the protective member 436a. When the magnetic block 436 moves between the first position and the second position, the protective member 436a and the contact 25 move relative to each other. The contact 25 is used to reduce the frictional force on the protective member 436a.

[0085] This allows the magnetic block 436 to move smoothly, thereby improving the working efficiency of the connecting device 200 to some extent.

[0086] Specifically, please combine Figure 2 and Figure 4 The processing platform 100 has a groove 10 on the side facing the base plate 300. The contact member 25 of the connecting mechanism 20 is located in the groove 10 and connected to the bottom wall of the groove 10. The magnetic block 436 of the switching mechanism 40 is also located in the groove 10, and the protective member 436a is in contact with the contact member 25. When an external force is applied to the operating member 41, when the magnetic block 436 moves between the first position and the second position, it can drive the protective member 436a and the contact member 25 to generate relative movement. The contact member 25 can reduce the friction of the protective member 436a, thereby reducing the resistance to the relative movement between the protective member 436a and the contact member 25, so that the magnetic block 436 can move smoothly, which improves the working efficiency of the connecting device 200 to a certain extent. At the same time, the contact member 25 can also reduce the wear of the protective member 436a, thereby improving the reliability of the magnetic block 436.

[0087] In some embodiments, the protective element 436a is a glass fiber protective element, and the contact element 25 is a glass fiber contact element.

[0088] This extends the service life of the protective component 436a and the contact component 25 to a certain extent.

[0089] Specifically, the protective component 436a is a fiberglass protective component, which can be used to protect the third magnetic component 436b and the fourth magnetic component 436c, which are spaced apart within the protective component 436a, and prevent the third magnetic component 436b and the fourth magnetic component 436c from being physically damaged during assembly, transportation, etc. The contact component 25 is a fiberglass contact component. When the protective component 436a and the contact component 25 move relative to each other, the fiberglass contacts each other, which can reduce the coefficient of friction to a certain extent, thereby reducing the frictional force of the protective component 436a and reducing wear, thus extending the service life of the protective component 436a and the contact component 25 to a certain extent.

[0090] In some embodiments, the connector 47 includes a pushing part 472, the connecting device 200 includes a resetting part 60, and the elastic member 49 is connected to the locking block 232 via the pushing part 472;

[0091] When the operating member 41 is locked, the pushing part 472 abuts against the locking block 232, causing the locking block 232 to be locked into the slot 212 and causing the locking block 232 to compress the reset member 60.

[0092] When the operating member 41 unlocks, the elastic member 49 resets to drive the pushing part 472 to move away from the card block 232, thereby driving the card block 232 to disengage from the card slot 212 when the reset member 60 resets.

[0093] Thus, the engagement and disengagement of the locking block 232 and the locking slot 212 can be achieved through the mutual cooperation between the elastic element 49, the pushing part 472 and the resetting part 60.

[0094] Specifically, please combine Figure 3 The pushing part 472 is the part of the connector 47 near the locking block 232. The elastic member 49 is connected to the locking block 232 through the pushing part 472. One end of the reset member 60 is connected to the locking block 232, and the other end is connected to the second connecting seat 23.

[0095] In one embodiment, when the operating member 41 is locked, the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436 is greater than the magnetic attraction force of the magnetic member 45 on the magnetic block 436, thus the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436 dominates. The magnetic repulsion force generated by the second magnetic member 434 on the magnetic block 436 can drive the magnetic block 436 to move away from the operating member 41 to a first position. In the first position, the magnetic block 436 can provide magnetic force to the first magnetic member 432. Optionally, the magnetic force provided to the first magnetic member 432 is a magnetic repulsion force. At this time, the magnetic force drives the first magnetic element 432 away from the magnetic block 436, causing the pushing part 472 of the connecting part 47 to move downward to abut against the locking block 232. Under the abutting action of the pushing part 472, the pushing part 472 pushes the locking block 232 to move and lock into the slot 212, thereby locking the first connecting seat 21 and the second connecting seat 23, and thus the processing platform 100 can be firmly locked onto the base plate 300. Since the magnetic force is greater than the elastic force, the elastic element 49 can be compressed, and at the same time, the movement of the locking block 232 causes the reset element 60 to be compressed. At this time, the tight engagement of the locking block 232 and the slot 212 and the reaction force generated by the compression of the reset element 60 can make the pushing part 472 and the locking block 232 tightly connected, and the processing platform 100 and the base plate 300 are in a stable locked state through the connecting device 200.

[0096] In one embodiment, when the operating member 41 is unlocked, the magnetic attraction force of the magnetic member 45 on the magnetic block 436 is greater than the magnetic repulsion force of the second magnetic member 434 on the magnetic block 436, thus the magnetic attraction force of the magnetic member 45 on the magnetic block 436 is dominant. The magnetic attraction force generated by the magnetic member 45 on the magnetic block 436 can drive the magnetic block 436 to move towards the operating member 41 to the second position. When the magnetic block 436 is in the second position, it does not provide magnetic force to the first magnetic member 432, or the magnetic force provided is less than the elastic force of the elastic member 49 when it is reset. At this time, the elastic member 49 extends from the compressed state, causing the pushing part 472 to move upward to allow the block 232 to disengage from the slot 212. Therefore, the block 232 disengages from the slot 212 under the action of the resetting member 60 when it is reset, thereby unlocking the first connecting seat 21 and the second connecting seat 23, and then removing the processing platform 100 from the base plate 300 for replacement or maintenance.

[0097] Optionally, the reset element 60 may be a spring.

[0098] In some embodiments, the pushing part 472 includes a first inclined surface 472a, and the locking block 232 includes a second inclined surface 232a;

[0099] During the process of the operating member 41 moving from the locked position to the unlocked position, the first inclined surface 472a and the second inclined surface 232a cooperate with each other to make the card block 232 disengage from the card slot 212 under the action of the reset member 60;

[0100] During the process of the operating member 41 moving from the unlocked position to the locked position, the first inclined surface 472a and the second inclined surface 232a come into contact with each other, causing the locking block 232 to be locked into the slot 212 under the action of the pushing part 472.

[0101] Thus, through the cooperation of the first inclined surface 472a and the second inclined surface 232a, the movement of the pushing part 472 and the locking block 232 is made more stable.

[0102] Specifically, please combine Figure 3 When the operating member 41 is in the locked position, the first inclined surface 472a of the pushing part 472 is completely separated from the second inclined surface 232a of the locking block 232. The end of the locking block 232 near the pushing part 472 abuts against the side of the pushing part 472 above the first inclined surface 472a, thereby locking the locking block 232 into the locking slot 212. At the same time, the reset member 60 is compressed. When the operating member 41 is in the unlocked position, the first inclined surface 472a and the second inclined surface 232a can contact each other, thereby forming a wedge-shaped structure.

[0103] In one embodiment, during the movement of the operating member 41 from the locked position to the unlocked position, the elastic force generated by the elastic member 49 causes the pushing part 472 to move upward. Simultaneously, due to the reset force of the reset member 60, the second inclined surface 232a pushes the first inclined surface 472a upward. Thus, during the switching process, the first inclined surface 472a and the second inclined surface 232a remain in contact, with no play in the entire movement, making the movement of the pushing part 472 and the locking block 232 more stable. When the connecting member 47 moves upward to its limit position, the first inclined surface 472a and the second inclined surface 232a form a wedge-shaped structure, allowing the locking block 232 to completely disengage from the slot 212. The operating member 41 is in the unlocked position, thereby unlocking the first connecting seat 21 and the second connecting seat 23. This allows the processing platform 100 to be removed from the base plate 300 for replacement or maintenance.

[0104] In one embodiment, during the movement of the operating member 41 from the unlocked position to the locked position, the magnetic force causes the pushing part 472 of the connecting member 47 to move downward, causing the first inclined surface 472a to contact the second inclined surface 232a. The first inclined surface 472a pushes the second inclined surface 232a outward, thereby causing the end of the locking block 232 near the pushing part 472 to abut against the side of the pushing part 472 located above the first inclined surface 472a. Under the abutment action of the pushing part 472, the locking block 232 moves towards the slot 212. When the first inclined surface 472a and the second inclined surface 232a are completely separated, the tight engagement of the locking block 232 with the slot 212 and the reaction force generated by the compression of the reset member 60 can ensure that the pushing part 472 and the locking block 232 are tightly connected, and the processing platform 100 and the base plate 300 are in a stable locked state through the connecting device 200.

[0105] In some embodiments, a locking block 232, a reset member 60, and a locking groove 212 are provided on each side perpendicular to the direction of movement of the pusher 472. The connecting device 200 also includes a connecting rod 80, which is fixed to the second connecting seat 23. The two reset members 60 and the two locking blocks 232 are movably sleeved on the connecting rod 80.

[0106] Thus, under the guidance of the connecting rod 80, the locking block 232 can be prevented from shifting or jamming, while the reset member 60 can apply an elastic force to the locking block 232 to achieve the separation of the locking block 232 from the slot 212.

[0107] Specifically, please combine Figure 3 The direction of movement of the pushing part 472 is up and down, and the direction perpendicular to the direction of movement of the pushing part 472 is horizontal, specifically the front and back direction shown in the figure. Each end of the connecting rod 80 is connected to a fixing part 81. The connecting rod 80 passes through the locking block 232, and the fixing parts 81 at both ends are fixedly connected to the inner wall of the second connecting seat 23 on both sides in the horizontal direction. The pushing part 472 is provided with a locking block 232, a reset member 60, and a slot 212 on each side in the front and back direction.

[0108] Taking one side in the forward / backward direction as an example, please combine... Figure 3The locking block 232 is provided with a guide portion 232b. One end of the connecting rod 80 passes through the guide portion 232b of the locking block 232 and is fixedly connected to the second connecting seat 23 through the fixing portion 81. The connecting rod 80 can restrict the direction of movement, that is, the locking block 232 can move along the length direction of the connecting rod 80 through the cooperation of the guide portion 232b and the connecting rod 80, so that the locking block 232 can accurately engage and disengage with the locking slot 212, avoiding the locking block 232 from shifting or jamming. The reset member 60 is sleeved on the connecting rod 80, and one end of the reset member 60 is connected to the guide portion 232b, and the other end is connected to the fixing portion 81. Thus, when the locking block 232 moves, the end of the reset member 60 connected to the guide portion 232b can stretch and contract with the movement of the locking block 232. When the pushing part 472 moves downward, the locking block 232 is abutted by the pushing part 472, and the locking block 232 engages with the locking groove 212. At this time, the reset member 60 is in a compressed state. When the pushing part 472 moves upward, the reset member 60 can apply an elastic force to the locking block 232, so that the locking block 232 can disengage from the locking groove 212.

[0109] In some embodiments, one of the first connecting seat 21 and the second connecting seat 23 is provided with a receiving cavity 214, and the other includes an insertion part 234, which is inserted into the receiving cavity 214, and a slot 212 is provided on the side wall of the receiving cavity 214.

[0110] Thus, on the one hand, the cooperation between the insertion part 234 and the receiving cavity 214 makes it easy to assemble the first connecting seat 21 and the second connecting seat 23; on the other hand, the multi-directional limiting can, to a certain extent, ensure that the first connecting seat 21 and the second connecting seat 23 are accurately positioned and stably connected in three-dimensional space, thereby improving the stability of the connecting device 200 to a certain extent.

[0111] Specifically, the cooperation between the receiving cavity 214 and the insertion part 234 limits the first connecting seat 21 and the second connecting seat 23 in the X and Y directions, while the cooperation between the locking block 232 and the locking groove 212 limits the first connecting seat 21 and the second connecting seat 23 in the Z direction. Please refer to... Figure 1 The X direction is forward and backward, the Y direction is left and right, and the Z direction is up and down. Please combine... Figures 2 to 4The first connecting seat 21 has a receiving cavity 214, and the second connecting seat 23 has an insertion part 234 adapted to the receiving cavity 214. The insertion part 234 is inserted into the receiving cavity 214, thereby connecting the first connecting seat 21 and the second connecting seat 23. When the insertion part 234 is inserted into the receiving cavity 214, the cooperation between the receiving cavity 214 and the insertion part 234 limits the first connecting seat 21 and the second connecting seat 23 in the X and Y directions. That is, the side walls of the receiving cavity 214 in the X direction and the side walls in the Y direction will block the insertion part 234. When an external force is applied in the X and Y directions, the insertion part 234 will contact the side walls of the receiving cavity 214, and the reaction force generated by the side walls will prevent the insertion part 234 from moving in the X and Y directions. Therefore, by cooperating with the accommodating cavity 214 and the insertion part 234 to limit the X and Y directions, the rigidity between the first connecting seat 21 and the second connecting seat 23 can be improved.

[0112] The slot 212 is located on the side wall of the receiving cavity 214 of the first connecting seat 21. The locking block 232 of the second connecting seat 23 can engage and disengage with the slot 212, thereby placing the first connecting seat 21 and the second connecting seat 23 in a locked and unlocked state, so as to realize the engagement and disengagement of the processing platform 100 and the base plate 300. When the locking block 232 is engaged in the slot 212, the mutual cooperation between the locking block 232 and the slot 212 limits the first connecting seat 21 and the second connecting seat 23 in the Z direction. That is, the side wall of the slot 212 in the Z direction will block the locking block 232. When an external force is applied in the Z direction, the insertion part 234 will contact the side wall of the receiving cavity 214, and the reaction force generated by the side wall will prevent the insertion part 234 from moving in the Z direction.

[0113] Therefore, multi-directional limiting can, to a certain extent, ensure that the first connecting seat 21 and the second connecting seat 23 are accurately positioned and stably connected in three-dimensional space, and prevent the processing platform 100 from becoming loose, offset or even separated from the base plate 300 due to the unreliable connection of the first connecting seat 21 and the second connecting seat 23, thereby improving the stability of the entire connecting device 200 to a certain extent.

[0114] Optionally, in other embodiments, the second connecting seat 23 is provided with a receiving cavity 214, and the first connecting seat 21 is provided with an insertion part 234 adapted to the receiving cavity 214. The insertion part 234 is inserted into the receiving cavity 214 so that the first connecting seat 21 and the second connecting seat 23 are connected.

[0115] Please see Figure 1 This utility model provides a machining equipment 1000, which includes a connecting device 200, a processing platform 100, and a base plate 300 as described in any of the above embodiments.

[0116] The first connecting seat 21 is connected to the processing platform 100, and the second connecting seat 23 is connected to the base plate 300.

[0117] In the aforementioned machining equipment 1000, the switching mechanism 40 can be switched by the position of the operating element 41, using the magnetic component 43 to provide magnetic force to the locking block 232 and using the elastic element 49 to reset, so that the locking block 232 engages and disengages from the locking slot 212, thereby putting the first connecting seat 21 and the second connecting seat 23 into locked and unlocked states, realizing the engagement and disengagement of the machining platform 100 and the base plate 300. Compared with the method of continuously using high-pressure gas to lock the machining platform 100, the cost of use is reduced to a certain extent.

[0118] Specifically, the machining equipment 1000 is an industrial equipment used to perform processing operations on raw materials, including but not limited to electrical discharge machining, laser cutting, cutting, grinding, stamping, forging, etc., to obtain parts or components that meet design requirements. Optionally, the machining equipment 1000 includes, but is not limited to, spark discharge machining equipment, CNC machining equipment (computer numerical control equipment), etc.

[0119] Please combine Figure 1 and Figure 2 The machining equipment 1000 includes a connecting device 200, a machining platform 100, and a base plate 300. The connecting device 200 connects the base plate 300 and the machining platform 100. The base plate 300 supports the machining platform 100 and provides mechanical support for it. The machining platform 100 supports the workpiece to be machined, thereby determining the position of the workpiece and fixing it for machining operations. The connecting device 200 includes a first connecting seat 21 and a second connecting seat 23. The first connecting seat 21 is fixedly connected to the machining platform 100 by means including but not limited to screws and pins. The second connecting seat 23 is fixedly connected to the base plate 300 by means including but not limited to screws and pins. Thus, the machining platform 100 can be detachably connected to the base plate 300 through the mutual cooperation of the first connecting seat 21 and the second connecting seat 23. Optionally, different machining platforms 100 can be used to machine different types of workpieces. Therefore, the detachable connection between the processing platform 100 and the base plate 300 facilitates the maintenance and disassembly of the processing platform 100, and allows for the replacement of different processing platforms 100 to adapt to the processing of different types of workpieces.
