Description

Technical Field

[0001] This invention relates to the field of machining technology, and in particular to a machining fixture, machining equipment, and screw fastening method. Background Technology

[0002] Currently, screw driving is used in the manufacturing process of most consumer electronics products to tightly connect and fix two or more components together using the threaded connection of fastener screws. The screw driving process requires the screw hole to be perpendicular to the screwdriver to ensure tightening force and positional accuracy. However, traditional screw driving machines or manual operation can only drive screws into screw holes on the same plane of the product on the same tooling. When screwing into screw holes on different surfaces or multiple screw holes with non-parallel axes, the tooling must be changed. This setup results in high tooling costs and low production efficiency due to frequent tooling changes.

[0006] In one embodiment, the rotary transmission mechanism includes:

[0007] Rotation axis; and

[0008] A connecting rod, one end of which is fixedly connected to the product fixing assembly, and the other end of which is movably connected to the rotating shaft; the connecting rod is movable relative to the rotating shaft to disengage from or move to one of the gear positions, and the rotating shaft drives the connecting rod and the product fixing assembly to rotate between two adjacent gear positions.

[0009] In one embodiment, the connecting rod is hinged to the rotation axis, and the hinge axis of the connecting rod is perpendicular to the axis of the rotation axis.

[0010] In one embodiment, the shift fixing seat is provided with a connecting groove and at least two limiting grooves, each of the limiting grooves forming a gear position; at least two limiting grooves are connected to the connecting groove; the rotating shaft can drive the connecting rod to rotate within the connecting groove.

[0011] In one embodiment, the machining fixture further includes a drive handle, which is fixedly connected to the product fixing component.

[0012] In one embodiment, the product fixing component includes:

[0013] Product holder, used to hold the product; and

[0014] A clamping assembly is movably mounted on the product fixing seat to clamp the product.

[0015] In one embodiment, the clamping assembly includes:

[0016] An electromagnet, said electromagnet being mounted on the product mounting base; and

[0017] The cover plate has one end movably connected to the product fixing seat and the other end magnetically connected to the electromagnet.

[0018] In one embodiment, the cover plate is hinged to the product mounting base.

[0019] The present invention also proposes a processing device, including the processing tooling described above.

[0020] The present invention also proposes a screw fastening method using the above-mentioned processing equipment, characterized in that the screw fastening method includes:

[0021] Place the product on the product fixing assembly and screw it onto the surface of the product facing the screw;

[0022] The rotary transmission mechanism is driven to switch gears to rotate the product, and the rotated product is then screwed in.

[0023] In one embodiment, the product fixing assembly includes a product fixing base, an electromagnet, and a cover plate, wherein the electromagnet is mounted on the product fixing base; one end of the cover plate is movably connected to the product fixing base, and the other end is magnetically connected to the electromagnet; after the step of driving the rotary transmission mechanism to switch gears and fastening screws to different surfaces of the product, the assembly further includes:

[0024] The current number of screws is compared with the preset number of screws, and the comparison result is generated.

[0025] Based on the comparison results, the state of the electromagnet is determined.

[0026] In one embodiment, the step of determining the state of the electromagnet based on the comparison result includes:

[0027] Determine whether the current number of screws being fastened is consistent with the preset number of screws being fastened;

Furthermore, by providing a shifting fixing seat with at least two positions, the rotary transmission mechanism is limited, ensuring that the product fixing component remains relatively stable after rotating to the required angle. This facilitates processing stability and provides a reminder to the user when the rotary transmission mechanism has reached its designated position. Attached Figure Description

[0046] This invention proposes a machining tooling.

[0047] In the embodiments of the present invention, please refer to the reference. Figures 1 to 3The processing fixture includes a product fixing component 100, a rotary transmission mechanism 200, and a shift fixing seat 300. The rotary transmission mechanism 200 is connected to the product fixing component 100 in a transmission manner. The shift fixing seat has at least two positions 310. The rotary transmission mechanism 200 can selectively move to any one of the positions 310, and the position 310 is used to limit the rotary transmission mechanism 200. The rotary transmission mechanism 200 switches between at least two positions 310 to drive the product fixing component 100 to flip.

[0048] The product fixing component 100 is used to fix the product, including clamping components for holding the product or clamping components for pressing the product, as long as the product can be fixed. The rotary transmission mechanism 200 is a transmission mechanism used to drive the product fixing component 100 to rotate. The rotary transmission mechanism 200 can be a linkage 220 mechanism, a gear assembly, or other components that can drive the product fixing component 100 to rotate. By connecting the rotary transmission mechanism 200 to the product fixing component 100 to drive the product fixing component 100 to rotate, the product fixing component 100 can be rotated at a certain angle, thereby achieving the effect of processing different sides of the same product on the same tooling. The processing technology in this invention can include cutting, extrusion molding, or screw-driving processes. This invention uses the screw-driving process as an example for explanation. Since screw-driving requires locking the screw in the screw hole along the axial direction of the screw hole, the direction of screw fastening has relatively strict requirements. When different surfaces of the product have screw holes that need to be fastened with screws, the product fixing component 100 can be rotated at a certain angle by the rotary transmission mechanism 200 to achieve the effect of fastening screws to the screw holes on different surfaces.

[0049] In addition, the processing fixture in this invention also includes a shift fixing seat 300, which has at least two positions 310. Each position 310 can limit the rotation transmission mechanism 200. The rotation transmission mechanism 200 can selectively move to any one of the positions 310 and can switch between the at least two positions 310 to drive the product fixing component 100 to rotate. When using this processing fixture, the user can drive the rotation transmission mechanism 200 to switch between the at least two positions 310, thereby achieving the effect of the rotation transmission mechanism 200 driving the product fixing component 100 to rotate between at least two angles to fasten screws to screw holes on different surfaces. The positions 310 of the shift fixing seat 300 can be implemented by setting limiting grooves, limiting blocks, or chucks. This setting can be set in the movement path of the rotation transmission mechanism 200, thereby limiting the rotation angle of the rotation transmission mechanism 200 to limit the rotation of the rotation transmission mechanism 200, so as to ensure that the product on the product fixing component 100 will not easily shake when the user fastens screws. For example, in one embodiment, the rotary transmission mechanism 200 may include a connecting rod 220. One end of the connecting rod 220 is connected to the product fixing assembly 100, and the other end of the connecting rod 220 can pass through the shift fixing seat 300 and connect to a universal hinge, thereby allowing the other end of the connecting rod 220 to rotate 360° to flip the product fixing assembly 100 in any direction. Depending on actual needs, a limiting part is provided on the shift fixing seat 300 to limit the connecting rod 220, so that the connecting rod 220 can be limited by the limiting part after rotating to a certain angle in a certain direction, thus ensuring a relatively stable effect for the product on the product fixing assembly 100. The limiting part can be a limiting groove, a claw, or other structure. When it is necessary to disengage from the limiting part, simply rotate the connecting rod 220 in the opposite direction. After disengaging from the limiting part, the connecting rod 220 can still rotate in any direction, thereby achieving the effect of flipping the product fixing assembly 100. It should be noted that the cooperation between the rotary transmission mechanism 200 and the shift fixing seat 300 is suitable for processing the surfaces of products with different directions, such as cuboids or irregular shapes. For example, the left side, top side and front side of the product can be processed on the processing fixture.

[0050] Alternatively, in one example, the rotary transmission mechanism 200 may include a meshing drive gear and a driven gear. The driven gear is connected to the product fixing assembly 100, so that when the driven gear rotates, it drives the product fixing assembly 100 to rotate. The driven gear is rotatably mounted on a shift fixing seat 300, which may have at least two elastic limiting balls spaced apart along the rotation direction of the driven gear. These elastic limiting balls form the shift positions 310 of the shift fixing seat 300. Each gear assembly has a limiting hole. When the driven gear rotates, the elastic limiting balls engage with the holes, thus achieving the limiting and positioning effects on the driven gear and the product fixing assembly 100. This facilitates the user's processing of the product on the product fixing assembly 100 when the product fixing assembly 100 is rotated to the current position. When it is necessary to disengage from the shift position 310 of the shift fixing seat 300, simply rotate the gear assembly. It should be noted that the cooperation between the rotary transmission mechanism 200 and the shift fixing seat 300 is suitable for processing at different positions in one circumference.

[0051] The technical solution of this invention connects the rotary transmission mechanism 200 to the product fixing component 100, allowing the rotary transmission mechanism 200 to drive the product fixing component 100 to rotate. This enables the product on the product fixing component 100 to rotate, aligning different surfaces of the product with the processing direction. This allows for the processing of different surfaces of the product on the same processing fixture, reducing the cost and time of changing fixtures, improving production efficiency, and enhancing processing accuracy. Furthermore, by providing a shift fixing seat 300 with at least two shift positions 310, the rotary transmission mechanism 200 can be limited, ensuring that the product fixing component 100 remains relatively stable after rotating to the required angle. This facilitates processing of the product on the product fixing component 100, ensuring stability during processing, and also provides a reminder to the user when the rotary transmission mechanism 200 has reached the correct rotation position.

[0052] In one example, please refer to the reference. Figures 1 to 3 The rotary transmission mechanism 200 includes a rotary shaft 210 and a connecting rod 220. One end of the connecting rod 220 is fixedly connected to the product fixing assembly 100, and the other end is movably connected to the rotary shaft 210. The connecting rod 220 moves relative to the rotary shaft 210 to disengage or move to one of the gear positions 310. The rotary shaft 210 drives the connecting rod 220 and the product fixing assembly 100 to rotate between two adjacent gear positions 310.

[0053] The rotating shaft 210 refers to a shaft capable of rotating along its own axis. One end of the connecting rod 220 is fixedly connected to the product fixing assembly 100, and the other end is movably connected to the rotating shaft 210. During rotation, the rotating shaft 210 can drive the connecting rod 220 and the product fixing assembly 100 to rotate together, thereby achieving the effect that the rotary transmission mechanism 200 can drive the product fixing assembly 100 to rotate. Specifically, when the connecting rod 220 is movably connected to the rotating shaft 210, it can be a sliding connection or a hinged connection.

[0054] By using a linkage 220 to move relative to the rotating shaft 210 to disengage from or move to one of the gear positions 310, and the rotating shaft 210 driving the linkage 220 and the product fixing assembly 100 to rotate between two adjacent gear positions 310, the linkage 220 can first move relative to the rotating shaft 210 to disengage from its current gear position 310 if it wants to switch gear positions 310. After disengaging from the current gear position 310, the linkage 220 can then move to another gear position 310 by driving the drive shaft to rotate, thus facilitating gear position switching for the linkage 220. Furthermore, this arrangement ensures that the rotary transmission mechanism 200 is effectively limited after rotating to a certain angle, and also makes it easier for the rotary transmission mechanism 200 to switch from one gear position 310 to another. The components of the rotary transmission mechanism 200 in this example are relatively simple and easy to operate.

[0055] Furthermore, such as Figure 2 As shown, the connecting rod 220 is hinged to the rotation shaft 210, and the hinge axis of the connecting rod 220 is perpendicular to the axis of the rotation shaft 210.

[0056] By hinged connecting rod 220 to rotating shaft 210, with the hinge axis of connecting rod 220 perpendicular to the axis of rotating shaft 210, connecting rod 220 can disengage from the current gear 310 by rotating relative to rotating shaft 210, and can enter the next gear 310 under the rotation of rotating shaft 210. This configuration allows disengagement from the current gear 310 by rotating connecting rod 220, a simple and effortless operation that reduces wear between parts. Furthermore, this configuration allows connecting rod 220 to rotate the product fixing assembly 100 once in each of the different rotation directions during gear shifting, making it suitable for products with multiple surfaces that need to be machined. This configuration also allows for quick and efficient rotation of the product fixing assembly 100 to the desired machining angle.

[0057] Of course, in other examples, the link 220 can also be slidably connected to the rotating shaft 210, and the link 220 can slide relative to the rotating shaft 210 in the axial direction of the rotating shaft 210, so that when the link 220 slides relative to the rotating shaft 210, it can disengage from the current gear 310.

[0058] Please refer to the reference. Figures 1 to 3 Based on the rotary transmission mechanism 200, the shift fixing seat 300 is provided with a connecting groove 320 and at least two limiting grooves, each limiting groove forming a gear position 310; at least two limiting grooves are connected to the connecting groove 320; the rotating shaft 210 can drive the connecting rod 220 to rotate within the connecting groove 320.

[0059] By providing at least two limiting grooves on the shift fixing seat 300, each limiting groove forming a position 310, the connecting rod 220 is effectively limited when inserted into the limiting groove at position 310. This ensures that the product fixing component 100 maintains a relatively stable state after moving to a certain angle with the connecting rod 220, facilitating processing of the product at the current angle. By providing a connecting groove 320, with at least two limiting grooves connected to it, the connecting rod 220 can switch between at least two positions 310. Furthermore, after moving into the connecting groove 320, the connecting rod 220 provides sufficient rotation space for the rotating shaft 210 to drive the connecting rod 220 to rotate. This allows the rotating shaft 210 to drive the product fixing component 100 to rotate via the connecting rod 220 to adjust the product's angle, thus enabling the user to process different surfaces of the product.

[0060] Furthermore, such as Figure 1 , Figure 2 or Figure 3 As shown, the machining fixture also includes a drive handle 400, which is fixedly connected to the product fixing assembly 100.

[0061] By providing a drive handle 400 fixedly connected to the product fixing component 100, the user can manually operate the drive handle 400 to drive the rotary transmission mechanism 200 to move between at least two gears 310 of the shift fixing seat 300, thereby adjusting the product angle and facilitating the processing of different surfaces of the product. Furthermore, with this configuration, when the rotary transmission mechanism 200 includes the aforementioned connecting rod 220 and rotating shaft 210, and the hinge axis of the connecting rod 220 is perpendicular to the axis of the rotating shaft 210, the user only needs one drive component to achieve the effect of driving the connecting rod 220 to rotate relative to the rotating shaft 210 and also driving the rotating shaft 210 to rotate, thus reducing the need for a separate drive device for driving the rotating shaft 210.

[0062] In one example, such as Figure 1 , Figure 2 or Figure 3 As shown, the product fixing assembly 100 includes a product fixing seat 110 and a clamping assembly. The product fixing seat 110 is used to place the product; the clamping assembly is movably disposed on the product fixing seat 110 and is used to clamp the product.

[0063] The product can be placed on the product fixing base 110. The clamping device is movably mounted on the product fixing base 110 and used to clamp the product, thus ensuring that the product can maintain a relatively stable state on the product fixing component 100. This also ensures that the product has a relatively stable effect when it is flipped with the product fixing component 100. Furthermore, when the rotary transmission mechanism 200 moves to the first position 310, it can ensure the accuracy of the product flipping angle, improving the processing precision of the product. In addition, by movably connecting the clamping component to the product fixing base 110, the clamping component can also cancel the clamping effect on the product on the product fixing base 110, making it easier for the user to pick up and put down the product. Specifically, the clamping component can be connected to the product fixing base 110 by means of hinge, sliding connection, etc.

[0064] Furthermore, such as Figure 1 , Figure 2 or Figure 3 As shown, the clamping assembly includes an electromagnet 120 and a cover plate 130. The electromagnet 120 is mounted on the product fixing base 110. One end of the cover plate 130 is movably connected to the product fixing base 110, and the other end is magnetically connected to the electromagnet 120.

[0065] Electromagnet 120 refers to a component that becomes magnetic when energized. By magnetically connecting electromagnet 120 to cover plate 130, the connection structure between the two can be reduced. Furthermore, the presence or absence of magnetism in electromagnet 120 can be controlled via circuitry, thereby controlling the cover plate 130 to press or release the product.

[0066] Furthermore, when this processing fixture is used in scenarios involving screw fastening on a product, the fixture also includes a control board. The control board has a counting unit and a comparison unit. The electromagnet 120 can be electrically connected to the comparison unit of the control board. The counting unit counts the number of screws fastened on the product, and the comparison unit compares the counted number with a preset number. If the comparison results match, it indicates that no screws have been missed. In this case, the electromagnet 120 can be de-energized, causing it to lose its magnetism and releasing the cover plate 130 from pressing the product, thus removing the product from the product holder 110. If the comparison results do not match, it indicates that some screws have been missed. In this case, the electromagnet 120 remains energized, maintaining a magnetic connection with the cover plate 130, which remains in the state of pressing the product. Simultaneously, an alarm device can be added. When the counted number of screws differs from the preset number, an alarm can be triggered. The alarm device can be a buzzer or a light, etc. When a screw is missed, the rotary transmission mechanism 200 can be driven to the corresponding gear 310 by checking the position of the missed screw to perform a screw fastening action on the position of the missed screw. The electromagnet 120 is only de-energized when the number of screws fastened on the product counted by the counting unit matches the preset number.

[0067] In one example, such as Figure 1 , Figure 2 or Figure 3 As shown, the cover plate 130 is hinged to the product mounting base 110.

[0068] By hinged to the product holder 110, the cover plate 130 can be easily opened or closed by the user. Furthermore, the cover plate 130 can be hinged to the product holder 110 via a torsion spring. With this configuration, when the electromagnet 120 is de-energized, the cover plate 130 can automatically spring up, making it easier to retrieve the processed product from the product holder 110 and reducing the need for manual operation to lift the cover plate 130 away from the product.

[0069] The present invention also proposes a processing device, which includes a processing fixture. The specific structure of the processing fixture is as described in the above embodiments. Since the processing device adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0070] This invention also proposes a screw fastening method, such as... Figure 4 As shown, this screw fastening method utilizes the aforementioned processing equipment. The screw fastening method includes:

[0071] S10: Place the product on the product fixing component 100 and screw it onto one surface of the product.

[0072] By placing the product on the product fixing component 100, the product achieves good stability, ensuring that the product's rotation angle is synchronized with that of the product fixing component 100 as it rotates, reducing the risk of the product slipping. Furthermore, when the product is placed on the product fixing component 100, one of the product's surfaces requiring screw fastening can be aligned with the screwdriver or the tightening direction used by the user when manually tightening screws, facilitating screw fastening immediately after the product is placed on the product fixing component 100.

[0073] S20: Drive the rotary transmission mechanism 200 to switch gears 310 to rotate the product and fasten the screws on the rotated product.

[0074] Understandably, a product can have multiple surfaces, each with screw holes for screw fastening. By driving the rotary transmission mechanism 200 to switch its gear 310, the product rotates, allowing the screw fastening process to be performed on the surface of the product facing the screw fastening machine. Specifically, when at least two surfaces of the product require screw fastening, the rotary transmission mechanism 200 is first driven to a gear 310 to perform screw fastening on one surface. After all screw holes on the surface are fastened, the rotary transmission mechanism 200 is switched to another preset gear 310 to perform screw fastening on the other surface, and so on, until all screw holes on all surfaces are fastened.

[0075] This invention achieves the effect of screw fastening on the screw holes of one surface of the product by placing the product on the product fixing component 100 and fastening the screws on the surface of the product facing the screws. By driving the rotary transmission mechanism 200 to switch gears 310, the rotary transmission mechanism 200 drives the product to rotate, so that the other surface of the product faces the screw fastening machine, allowing the screw fastening machine to fasten the screws on the other surface of the product. Therefore, the screw fastening method of this invention can achieve the effect of screw fastening on different surfaces of the product on the same tooling, reducing the need to change tooling, thereby saving tooling costs, reducing the time required for tooling changes, and improving production efficiency.

[0076] Furthermore, please refer to the following: Figures 1 to 4The product fixing assembly 100 includes a product fixing base 110, an electromagnet 120, and a cover plate 130. The electromagnet 120 is mounted on the product fixing base 110. One end of the cover plate 130 is movably connected to the product fixing base 110, and the other end is magnetically connected to the electromagnet 120. S20: After the step of driving the rotary transmission mechanism 200 to move to the preset position 310 and tightening the screws on the product, the assembly further includes:

[0077] S30: Compare the current number of screws with the preset number of screws and generate the comparison result.

[0078] The processing equipment also includes a counting unit to count the number of screws fastened to the product, and a comparison unit to compare the count with a preset quantity. If the comparison results match, it means that no screws were missed; if the comparison results do not match, it means that some screws were missed.

[0079] S40: Determine the state of electromagnet 120 based on the comparison results.

[0080] When the comparison results are consistent, it indicates that no screws have been missed. In this case, the state of electromagnet 120 can be changed to make cover plate 130 latch, thus facilitating the removal of the product from product holder 110. When the comparison results are inconsistent, it indicates that some screws have been missed. In this case, the electromagnet 120 can be kept energized to ensure that cover plate 130 remains in a state of pressing the product. This avoids the risk of giving the user incorrect signals, allowing them to easily remove the product from product holder 110 even with missing screws.

[0081] Furthermore, in one example, please refer to the reference. Figure 4 and Figure 5 S40: The steps for determining the state of electromagnet 120 based on the comparison results include:

[0082] S41: Determine whether the current number of screws being fastened is consistent with the preset number of screws being fastened;

[0083] S42: If so, release the magnetic force of electromagnet 120.

[0084] By checking if the current number of screws matches the preset number, it can be determined whether any screws have been missed. If the current number of screws matches the preset number, it means no screws have been missed, and the screw fastening process for all screw holes of multiple products is now complete. At this point, releasing the magnetic force of the electromagnet 120 causes it to lose its attraction to the cover plate 130, allowing the product to be removed by opening the cover plate 130 and replaced with the next product for screw fastening on the product holder 110.

[0085] Furthermore, in another example, please refer to [reference needed]. Figure 4 and Figure 6 S40: The steps for determining the state of electromagnet 120 based on the comparison results include:

[0086] S41: Determine whether the current number of screws being fastened is consistent with the preset number of screws being fastened;

[0087] S43: If not, keep electromagnet 120 energized.

[0088] By checking whether the current number of screws matches the preset number, it can be determined whether any screws have been missed. If the current number of screws does not match the preset number, it indicates that some screws have been missed. In this case, by energizing the electromagnet 120, the user cannot manually open the cover 130, thus ensuring that the cover 130 can press the product firmly and preventing the user from removing the product with the missing screws.

[0089] Furthermore, the processing equipment can be equipped with an alarm device. If the current number of screws being tightened does not match the preset number, an alarm can be triggered. This alarm device can be a buzzer or a light, etc.

[0090] Furthermore, when the user needs to continue checking the location of the missing screws, after rotating the rotary transmission mechanism 200 to the corresponding gear 310 and securing the missing screws, the user repeats steps S30 to S40 until the comparison results are consistent before releasing the magnetic force of the electromagnet 120.

[0091] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
