Technical Field

[0001] This application relates to the field of machining tooling technology, and in particular to a fixed tooling. Background Technology

[0002] In the field of workpiece machining, fixed fixtures provide stable support for the workpiece to be processed and fix it in place. Existing fixed fixtures mostly adopt a single magnetic suction or clamping structure, which has poor versatility. Utility Model Content

[0003] This application provides a fixed tooling to solve the problem of poor versatility of existing fixed tooling.

[0004] This application provides a fixed tooling, comprising:

[0005] A carrier plate, which is used to support the workpiece to be processed;

[0006] A clamping plate, which is detachably connected to the carrier plate, and a limiting hole is provided on the clamping plate;

[0007] The limiting part has a connecting rod and a limiting block. The limiting block is disposed at one end of the connecting rod and cooperates with the limiting hole to limit the position.

[0008] A first driving unit, capable of driving the clamping plate away from the limiting unit;

[0009] The second driving unit is capable of driving the limiting block to cooperate with the limiting hole for limiting;

[0010] The body, the first drive unit and the second drive unit are both disposed on the body.

[0011] In one possible design, the limiting block has at least one protrusion, the maximum distance between the edge of the protrusion and the axis of the connecting rod being greater than the minimum distance between the edge of the limiting hole and the axis of the connecting rod.

[0012] In one possible design, the body has a top plate, a bottom plate, and a column located between the top plate and the bottom plate, with the first drive unit and the second drive unit disposed between the top plate and the bottom plate;

[0013] The top plate is provided with a first through hole and a second through hole. The first driving part can pass through the first through hole, and the connecting rod passes through the second through hole and contacts the second driving part.

[0014] In one possible design, the second driving unit is connected to the end of the connecting rod where the limiting block is not located, and the second driving unit is capable of driving the connecting rod and the limiting block to rotate and move downward.

[0015] In one possible design, the limiting part further includes: a limiting member disposed on the top plate, wherein the end of the connecting rod without the limiting block passes through a through hole on the limiting member and is connected to the second driving part, and the second driving part is capable of driving the connecting rod to move;

[0016] The limiting member has a sliding groove that is arranged upward along the circumference of the limiting member; the connecting rod is provided with a sliding rod that is slidably connected to the sliding groove.

[0017] In one possible design, the limiting member includes a cylindrical portion and a connecting end, the groove being disposed on the cylindrical portion, the cylindrical portion being able to extend into the second through hole, and the connecting end having a size larger than the size of the second through hole.

[0018] In one possible design, one of the body and the clamping plate is provided with a guide pin, and the other is provided with a guide hole, the guide pin being able to engage with the guide hole.

[0019] In one possible design, one of the body and the clamping plate is provided with a foolproof pin, and the other is provided with a foolproof hole, the foolproof pin being able to engage with the foolproof hole.

[0020] In one possible design, the top plate is provided with a support column that can abut against the side of the clamping plate away from the carrier plate.

[0021] In one possible design, the fixing fixture further includes a connector, the carrier plate having a first mounting hole, the clamping plate having a second mounting hole, and the connector being connected to the first mounting hole and the second mounting hole.

[0022] In this application, the clamping plate and the carrier plate are detachably connected, so the clamping plate can be used with different carrier plates, and different carrier plates can be adapted to workpieces of different shapes, so that the fixture can be used to support and fix workpieces of different shapes, thereby making the fixture highly versatile.

[0023] The limiting part has a locked state and an unlocked state. When the limiting part is in the locked state, the projection of the limiting block on the clamp plate does not coincide with the limiting hole at least partially, thereby restricting the movement of the clamp plate. When the limiting part is in the unlocked state, the projection of the limiting block on the clamp plate coincides with the limiting hole, so that the limiting block does not restrict the movement of the clamp plate.

[0024] When the carrier plate is mounted on the clamping plate, it can move with the clamping plate. When the fixing fixture is not fixed to the clamping plate, i.e., the limiting part is in the unlocked state, the first drive unit can drive the clamping plate to move relative to the machine body, changing the position of the clamping plate and thus changing the position of the carrier plate. When the fixing fixture fixes the clamping plate, the second drive unit drives the limiting block to engage with the limiting hole, causing the limiting part to change to the locked state, thus fixing the position of the clamping plate. At this time, the position of the carrier plate is fixed, and the processing equipment can process the workpiece on the carrier plate. During this process, the workpiece on the carrier plate remains stationary, allowing processing to proceed smoothly. The fixing fixture, through the engagement of the limiting block and the limiting hole, can achieve rapid positioning and disassembly of the clamping plate, facilitating quick replacement of the carrier plate, and also has the advantages of simple structure and reliability.

[0025] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit this application. Attached Figure Description

[0067] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0068] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0069] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0070] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0071] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0072] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0073] This application provides a fixed tooling, such as Figures 1-4As shown, the fixed fixture includes: a carrier plate 1, a clamping plate 2, a limiting part 3, a first driving part 4, a second driving part 5, and a machine body 6. The carrier plate 1 is used to support the workpiece to be processed. The clamping plate 2 is detachably connected to the carrier plate 1. The clamping plate 2 is provided with a limiting hole 22. The limiting part 3 has a connecting rod 31 and a limiting block 32. The limiting block 32 is disposed at one end of the connecting rod 31 and cooperates with the limiting hole 22 to limit the position. The first driving part 4 can drive the clamping plate 2 away from the limiting part 3, and the second driving part 5 can drive the limiting block 32 to cooperate with the limiting hole 22 to limit the position. The first driving part 4 and the second driving part 5 are both disposed on the machine body 6.

[0074] For ease of description, the height direction of the fixed tooling is defined as the first direction X, and the length direction as the second direction Y. It is understood that the first direction X is not limited to the height direction of the fixed tooling; it can also be the length direction, width direction, or other directions of the fixed tooling. Similarly, the second direction Y is not limited to the length direction of the fixed tooling.

[0075] The clamping plate 2 is detachably connected to the carrier plate 1, so the clamping plate 2 can be used with different carrier plates 1. Different carrier plates 1 can be adapted to workpieces of different shapes, so that the fixture can be used to support and fix workpieces of different shapes, thus making the fixture highly versatile.

[0076] The limiting part 3 has a locked state and an unlocked state. When the limiting part 3 is in the locked state, the projection of the limiting block 32 on the clamping plate 2 along the first direction X is at least partially not coincident with the limiting hole 22, thereby restricting the movement of the clamping plate 2 along the first direction X. When the limiting part 3 is in the unlocked state, the projection of the limiting block 32 on the clamping plate 2 along the first direction X coincides with the limiting hole 22, so that the limiting block 32 does not restrict the movement of the clamping plate 2 along the first direction X.

[0077] When the carrier plate 1 is mounted on the clamping plate 2, the carrier plate 1 can move with the clamping plate 2. When the fixing fixture is not fixing the clamping plate 2, that is, the limiting part 3 is in the unlocked state, the first driving part 4 can drive the clamping plate 2 to move relative to the machine body 6, changing the position of the clamping plate 2 in the first direction X, and thus changing the position of the carrier plate 1 in the first direction X. When the fixing fixture fixes the clamping plate 2, the second driving part 5 drives the limiting block 32 to cooperate with the limiting hole 22, so that the limiting part 3 changes to the locked state, fixing the position of the clamping plate 2 in the first direction X. At this time, the position of the carrier plate 1 is fixed, and the processing equipment can process the workpiece on the carrier plate 1. During this process, the workpiece on the carrier plate 1 remains stationary, so that the processing can proceed smoothly. The fixing fixture, through the cooperation of the limiting block 32 and the limiting hole 22, can realize the quick positioning and disassembly of the clamping plate 2, which facilitates the quick replacement of the carrier plate, and has the advantages of simple structure and reliability.

[0078] Optionally, there are two second drive units 5, which are arranged on both sides of the first drive unit 4 along the second direction Y, preferably symmetrically arranged, and move synchronously. Correspondingly, there are two limiting units 3, and the two limiting units 3 provide a more reliable fixing effect on the clamping plate 2.

[0079] Specifically, such as Figure 1 and Figure 3 As shown, the fixing fixture also includes: a connector; the carrier plate 1 is provided with a first mounting hole 11, and the clamping plate 2 is provided with a second mounting hole 25; the connector is connected to the first mounting hole 11 and the second mounting hole 25 to achieve a detachable connection between the carrier plate 1 and the clamping plate 2; the connector can be a bolt. Both the carrier plate 1 and the clamping plate 2 can be rectangular plates. There are two first mounting holes 11, located at opposite corners of the carrier plate 1; and correspondingly, there are two second mounting holes 25, located at opposite corners of the clamping plate 2. Therefore, the two connectors are connected to the first mounting hole 11 and the second mounting hole 25 at opposite corners, respectively, so that the carrier plate 1 and the clamping plate 2 are connected at opposite corners, thus preventing the carrier plate 1 from moving relative to the clamping plate 2 and synchronizing their movements.

[0080] More specifically, such as Figure 5 As shown, the body 6 has a top plate 61, a bottom plate 62, and columns 63 located between the top plate 61 and the bottom plate 62. A first drive unit 4 and a second drive unit 5 are disposed between the top plate 61 and the bottom plate 62. Four columns 63 are provided, each located at one of the four corners of the bottom plate 62, providing support to the four corners of the top plate 61. The top plate 61, the bottom plate 62, and the columns 63 form an accommodating space, facilitating the placement of the first drive unit 4 and the second drive unit 5.

[0081] The top plate 61 is provided with a first through hole 611 and a second through hole 612. The first driving part 4 can pass through the first through hole 611 and thus contact the clamping plate 2, pushing the clamping plate 2 to move in the first direction X. The connecting rod 31 passes through the second through hole 612 and contacts the second driving part 5, thus being driven by the second driving part 5 to switch the limiting part 3 between the locked state and the unlocked state.

[0082] Optionally, one first through hole 611 is provided, and two second through holes 612 are provided, with the two second through holes 612 disposed on both sides of the first through hole 611 along the second direction Y.

[0083] Furthermore, such as Figure 3 and Figure 5 As shown, one of the body 6 and the clamping plate 2 is provided with a guide pin 613, and the other is provided with a guide hole 23. The guide pin 613 can cooperate with the guide hole 23 to guide the clamping plate 2 to move along a preset path, prevent the clamping plate 2 from deviating, and improve the working stability of the fixed tooling.

[0084] Specifically, the guide pin 613 can be disposed on the top plate 61 of the body 6. Along the direction away from the top plate 61, the guide pin 613 and the guide hole 23 can be clearance-fitted. The cross-sectional dimension of the portion of the guide pin 613 that first enters the guide hole 23 gradually decreases, making it easier for the guide pin 613 to extend into the guide hole 23 and reducing the difficulty of their fit. The guide pin 613 has multiple radially recessed recesses. When the guide pin 613 fits with the guide hole 23, these recesses reduce the contact area between the guide pin 613 and the peripheral wall of the guide hole 23, thereby reducing the frictional force experienced by the clamping plate 2 when it moves along the first direction X, making the movement of the clamping plate 2 smoother.

[0085] Optionally, two guide pins 613 are provided, with the two guide pins 613 respectively disposed on the side of the two second through holes 612 away from each other along the second direction Y.

[0086] Furthermore, such as Figure 3 and Figure 5 As shown, one of the body 6 and the clamping plate 2 is provided with a foolproof pin 614, and the other is provided with a foolproof hole 24. The foolproof pin 614 can cooperate with the foolproof hole 24, so that the clamping plate 2 can only be installed on the body 6 in a specific direction, preventing the part from being machined incorrectly due to the clamping plate 2 being installed backwards.

[0087] Optionally, a support column 615 is provided on the top plate 61. The support column 615 can abut against the side of the clamping plate 2 away from the carrier plate 1 to limit the minimum distance between the clamping plate 2 and the top plate 61, preventing the clamping plate 2 from sticking to the top plate 61 and making it difficult to remove the clamping plate 2. Four support columns 615 can be provided, and the four support columns are evenly arranged on the circumferential outer side of the first through hole 611 and the second through hole 612.

[0088] In one specific implementation, such as Figure 4 As shown, the limiting block 32 has at least one protrusion, and the maximum distance between the edge of the protrusion and the axis of the connecting rod 31 is greater than the minimum distance between the edge of the limiting hole 22 and the axis of the connecting rod 31, so that the limiting block 32 can move to a state in which its projection on the clamping plate 2 along the first direction X is at least partially not coincident with the limiting hole 22.

[0089] Optional, such as Figure 3 and Figure 4 As shown, the limiting block 32 has two protrusions, which are symmetrically arranged. The shape of the limiting hole 22 corresponds to the shape of the limiting block 32. The two protrusions can be a single piece, directly installed in the mounting groove at the end of the connecting rod 31, thereby reducing the number of parts of the fixing fixture and facilitating the assembly of the fixing fixture. In this case, the second drive unit 5 can be a rotary pressing cylinder.

[0090] Optional, such as Figure 7 and Figure 8 As shown, the limiting block 32 has six protrusions, which are mounted as a whole at the end of the connecting rod 31.

[0091] Specifically, the second drive unit 5 is connected to the end of the connecting rod 31 without the limiting block 32, and the second drive unit 5 can drive the connecting rod 31 and the limiting block 32 to rotate downward or upward.

[0092] The clamping plate 2 has a limiting groove 21, and a limiting hole 22 penetrates the bottom wall of the limiting groove 21. By adjusting the posture of the connecting rod 31 and the limiting block 32, the limiting block 32 can be rotated upward so that it passes through the limiting hole 22 and enters the limiting groove 21, and then rotates to abut against the bottom wall of the limiting groove 21. Similarly, when the limiting block 32 rotates downward, it can also pass through the limiting hole 22 and leave the limiting groove 21. Therefore, the second driving unit 5 drives the connecting rod 31 and the limiting block 32 to rotate downward so that the limiting part 3 can change from a locked state to an unlocked state, and the second driving unit 5 drives the connecting rod 31 and the limiting block 32 to rotate upward so that the limiting part 3 can change from an unlocked state to a locked state.

[0093] In another specific implementation, such as Figures 6-9 As shown, the limiting part 3 also includes: a limiting member 64 disposed on the top plate 61, the end of the connecting rod 31 without the limiting block 32 passing through the through hole 643 on the limiting member 64 and connected to the second driving part 5, the second driving part 5 being able to drive the connecting rod 31 to move; the limiting member 64 has a sliding groove 641a, the sliding groove 641a being disposed upward along the circumference of the limiting member 64; a sliding rod 33 is disposed on the connecting rod 31, the sliding rod 33 being slidably connected to the sliding groove 641a.

[0094] When the second drive unit 5 drives the connecting rod 31 to move along the first direction X, the sliding rod 33 slides along the slide groove 641a. Since the slide groove 641a is arranged to rise along the circumference of the limiting member 64, the connecting rod 31 rotates, which is either rotating downward or rotating upward.

[0095] Similarly, when the limiting block 32 rotates upward, it can just pass through the limiting hole 22 and enter the limiting groove 21. Then the limiting block 32 rotates until it abuts against the bottom wall of the limiting groove 21, that is, the limiting part 3 changes from the unlocked state to the locked state. When the limiting block 32 rotates downward, the limiting block 32 can just pass through the limiting hole 22 and leave the limiting groove 21, that is, the limiting part 3 changes from the locked state to the unlocked state.

[0096] Specifically, such as Figure 9As shown, the limiting member 64 includes a cylindrical portion 641 and a connecting end 642. A groove 641a is provided on the cylindrical portion 641. The cylindrical portion 641 can extend into the second through hole 612. The size of the connecting end 642 is larger than the size of the second through hole 612, so that the connecting end 642 can abut against the side of the top plate 61 facing the bottom plate 62 and can be fixed on the top plate 61.

[0097] The through hole 643 extends axially through the cylindrical portion 641 and the connecting end 642, and the sliding groove 641a connects the through hole 643 to the outside. The connecting rod 31 and the sliding rod 33 can be separately provided, which facilitates the installation of the sliding rod 33 onto the connecting rod 31 after the connecting rod 31 passes through the through hole 643, thereby facilitating the assembly of the fixing fixture.

[0098] In the above embodiments, such as Figure 10 As shown, the fixture also includes a protective cover 7 and a switch handle 8. The protective cover 7 is located between the top plate 61 and the bottom plate 62, and can protect the first drive unit 4 and the second drive unit 5, so that the first drive unit 4 and the second drive unit 5 can work in a stable state. The first drive unit 4 and the second drive unit 5 can be controlled by the switch handle 8.

[0099] The first drive unit 4 and the second drive unit 5 can be cylinders.

[0100] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
