Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning fixture technology, and in particular to a bidirectional clamping positioning fixture. Background Technology
[0002] When clamping and positioning a product, two drive components are usually needed to drive two clamping components to clamp and position the product from two directions to ensure the accurate positional relationship of the product. However, the setting of two drive components requires the simultaneous configuration of multiple matching sensors or other auxiliary structures, which makes the fixture structure redundant. Moreover, the setting of multiple drive components increases the failure rate of the fixture.
[0003] In related technologies, a dual-push-block clamping carrier is provided, including a base, a positioning block, a clamping assembly, and two wedge blocks. The positioning block is disposed on the top of the base. The clamping assembly includes a main push block and a secondary push block disposed on the top of the base. The main push block can move closer to or away from the positioning block along a first direction, and the secondary push block can move closer to or away from the positioning block along a second direction perpendicular to the first direction. The two wedge blocks are fixedly connected to the main push block and the secondary push block respectively, and the two wedge blocks are slidably connected. When the main push block moves away from the positioning block, it can synchronously drive the secondary push block away from the positioning block through the two wedge blocks. However, during the long-term sliding process, the corresponding sliding surfaces of the two wedge blocks will wear, and the mating clearance of the wedge blocks will increase, causing the main push block and the secondary push block to be unable to clamp or move away synchronously, reducing the clamping reliability.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.
[0049] This embodiment provides a bidirectional clamping and positioning fixture, such as Figure 1 and Figure 2As shown, the fixture includes a fixture body 1, a positioning unit 2, a clamping unit 3, and a linkage unit 4. A driving component 8 is provided on the fixture body 1. The positioning unit 2 is used to position and place the product. The clamping unit 3 includes a first clamping component 31 and a second clamping component 32 that are slidably connected to the fixture body 1. The output end of the driving component 8 is connected to the first clamping component 31 or the second clamping component 32. The first clamping component 31 can approach the product along a first direction, and the second clamping component 32 can approach the product along a second direction. The first direction and the second direction are set at an angle. The linkage unit 4 includes a linkage assembly that is movably connected to the fixture body 1. Both the first clamping component 31 and the second clamping component 32 are connected to the linkage assembly.
[0050] When clamping the product, the drive unit 8 is activated, driving either the first clamping assembly 31 or the second clamping assembly 32 to move. Due to the linkage effect of the linkage assembly, the first clamping assembly 31 moves closer to the product along the first direction, and the second clamping assembly 32 moves closer to the product along the second direction, clamping the product simultaneously. By linking the first clamping assembly 31 and the second clamping assembly 32 through the linkage assembly, the force on the linkage assembly is uniform, avoiding wear or deformation, which helps to improve the synchronicity of clamping the product by the first clamping assembly 31 and the second clamping assembly 32, and the clamping force in the two directions is balanced, avoiding positioning deviation caused by uneven force on the product.
[0051] Specifically, in such Figure 1 and Figure 2 As shown, in this embodiment, the first direction and the second direction are perpendicular to each other. In other embodiments, the angle between the first direction and the second direction is 75°, 60°, or 45°, etc. No limitation is made here. More specifically, in this embodiment, the first direction is... Figure 1 The front and back directions, the second direction is Figure 1 The left and right directions in the middle.
[0052] Specifically, such as Figure 2 As shown, in this embodiment, the output end of the drive member 8 is drive-connected to the first clamping assembly 31. In other embodiments, the output end of the drive member 8 is drive-connected to the second clamping assembly 32. No limitation is made here.
[0053] Specifically, such as Figure 2 As shown, in this embodiment, the output end of the drive component 8 is threadedly connected to the first clamping assembly 31. In other embodiments, the output end of the drive component 8 is connected to the first clamping assembly 31 via a gear and rack, or via a cam mechanism, etc. No limitation is made here. It should be noted that in this embodiment, the drive component 8 is a drive cylinder. In other embodiments, the drive component 8 can also be a linear motor, an electric cylinder, or a rotary motor, etc. No limitation is made here.
[0054] Optionally, such as Figure 1 and Figure 2 As shown, the fixture body 1 includes a first body 11 and a second body 12. The first body 11 has a first through hole 111 and a second through hole 112. The first through hole 111 extends along a first direction, and the second through hole 112 extends along a second direction. A portion of the first clamping assembly 31 is accommodated in the first through hole 111, and a portion of the second clamping assembly 32 is accommodated in the second through hole 112. The second body 12 and the first body 11 are arranged parallel to each other along a third direction. The driving member 8 is disposed on the second body 12, and the linkage unit 4 is movably connected to the second body 12. Another portion of the first clamping assembly 31 and another portion of the second clamping assembly 32 are slidably connected to the second body 12. The driving member 8, the linkage unit 4, the other portion of the first clamping assembly 31, and the other portion of the second clamping assembly 32 are located between the first body 11 and the second body 12. The first direction, the second direction, and the third direction are perpendicular to each other. Part of the first clamping assembly 31 and part of the second clamping assembly 32 are disposed within the through hole, and the driving component 8, the linkage unit 4, another part of the first clamping assembly 31, and another part of the second clamping assembly 32 are located between the first body 11 and the second body 12, so that the first clamping assembly 31 and the second clamping assembly 32 clamping the product are exposed, while other structures are located between the first body 11 and the second body 12. This protects the internal components and makes the overall structure simpler, avoiding unnecessary structures from interfering with the clamping operation. Specifically, in this embodiment, along the third direction, the first body 11 is disposed above the second body 12. In other embodiments, along the third direction, the first body 11 is disposed below the second body 12, etc. No limitation is made here. It should be noted that the third direction is... Figure 1 The up and down directions in the middle.
[0055] Optionally, such as Figure 1 As shown, the bidirectional clamping and positioning fixture also includes a product presence detection element 7 disposed on the fixture body 1. The product presence detection element 7 is electrically connected to the drive element 8 and is used to detect whether the product is positioned in the positioning unit 2. When the product presence detection element 7 detects that the product is positioned in the positioning unit 2, the drive element 8 is activated. This prevents the drive element 8 from running idle when there is no product, reduces mechanical wear and accidental risks, improves safety, reduces manual intervention steps, and enhances the degree of automation.
[0056] Specifically, in this embodiment, the product has a detection component 7, which is an existing structure. Any existing detection component can be used. Further details are omitted here.
[0057] Optionally, in this embodiment, the bidirectional clamping and positioning fixture further includes a controller, and both the product presence detection element 7 and the driving element 8 are electrically connected to the controller. Specifically, in this embodiment, the controller is a conventional structure. Any controller with a conventional structure can be used. Further details are omitted here.
[0058] Optionally, such as Figure 1 As shown, the positioning unit 2 includes multiple positioning blocks 21 arranged at intervals, and the product can be engaged and positioned with the positioning blocks 21. The arrangement of multiple positioning blocks 21 enables multi-point positioning of the product and also reduces the material required for the positioning unit 2. It should be noted that the positioning unit 2 is disposed on the first main body 11.
[0059] Optionally, such as Figures 1-3 As shown, the linkage assembly includes a first link 41, a V-shaped link 42, and a second link 43. The first link 41 is rotatably connected to the first clamping assembly 31. The first end of the V-shaped link 42 is rotatably connected to the first link 41 via a first rotating shaft, and the tip of the V-shaped link 42 is rotatably connected to the fixture body 1. The second link 43 is connected to the second clamping assembly 32, and the second link 43 is rotatably connected to the second end of the V-shaped link 42 via a second rotating shaft. When the driving member 8 drives the first clamping assembly 31 to approach the product along a first direction, the first link 41 moves, causing the V-shaped link 42, which is rotatably connected to the first link 41, to rotate around its tip. Simultaneously, this drives the second link 43 to move, so that the second clamping assembly 32 moves towards the product along a second direction, achieving bidirectional clamping of the product. Specifically, in this embodiment, the tip of the V-shaped link 42 is rotatably connected to the second body 12.
[0060] Optionally, such as Figure 3 As shown, the fixture body 1 has a first sliding groove 121 and a second sliding groove 122 arranged at intervals. The first rotating shaft can be slidably connected to the first sliding groove 121, and the second rotating shaft can be slidably connected to the second sliding groove 122. When the linkage assembly is linked with the first clamping assembly 31 and the second clamping assembly 32, the first rotating shaft slides in the first sliding groove 121, and the second rotating shaft slides in the second sliding groove 122. The two sliding grooves respectively restrict and guide the sliding trajectory of the two rotating shafts, ensuring that the linkage assembly does not interfere with other structures during movement, and also enabling precise control of the movement posture of the linkage assembly. The design of the first sliding groove 121 and the second sliding groove 122 achieves multiple effects of guidance, limitation, anti-interference, and posture stabilization.
[0061] Specifically, such as Figure 3As shown, in this embodiment, both the first groove 121 and the second groove 122 are arc-shaped waist grooves. The radius of the first groove 121 is the same as the length of the first arm of the V-shaped connecting rod 42, and the radius of the second groove 122 is the same as the length of the second arm of the V-shaped connecting rod 42. The arc-shaped waist groove design better conforms to the movement trajectory of the first and second rotating shafts. When the rotating shaft slides, it will apply a radial force to the arc-shaped waist groove. The curved surface structure of the arc-shaped waist groove can evenly distribute the force to the entire contact arc segment, avoiding stress concentration.
[0062] Optionally, such as Figure 2 and Figure 4 As shown, the first clamping assembly 31 includes a first clamping body 311 and a first buffer 312. The first clamping body 311 is connected to the output end of the driving member 8. The first buffer 312 is disposed on the first clamping body 311 and can clamp the product along a first direction. When the driving member 8 drives the first clamping body 311 to approach the product along the first direction, the first buffer 312 disposed on the first clamping body 311 clamps the product. The first buffer 312 can provide a certain buffering capacity for clamping the product and avoid damage to the clamped product. It should be noted that in this embodiment, the first clamping body 311 is an L-shaped clamping block. In other embodiments, the first clamping body 311 is a square clamping block or a clamping plate, etc. No limitation is made here.
[0063] Specifically, such as Figure 4 As shown, the first buffer 312 includes a fixing part 3121, a buffer part 3122, an elastic part 3123, and a locking part 3124. The fixing part 3121 is embedded in the first clamping body 311, the buffer part 3122 passes through the fixing part 3121, and the elastic part 3123 is sleeved on the buffer part 3122. Along the sliding direction of the buffer part 3122, one end of the elastic part 3123 abuts against the buffer part 3122, and the other end abuts against the fixing part 3121. When the first buffer 312 approaches the product, the buffer part 3122 is first squeezed by the product and slides away from the product relative to the fixing part 3121. The elastic part 3123 is squeezed and generates an elastic force opposite to the product's squeezing force, providing a buffering effect for the buffer part 3122 and avoiding damage to the product from hard contact. It should be noted that in this embodiment, the elastic part 3123 is a spring. In other embodiments, the elastic part 3123 is an elastic pad, a rubber sleeve, or a silicone sleeve, etc. No restrictions are imposed here. It should be noted that the sliding direction of the buffer section 3122 is the first direction.
[0064] Specifically, in this embodiment, the buffer portion 3122 is a stepped buffer rod, with the larger radius end located on one side of the product. In other embodiments, the buffer portion 3122 can be other structures such as pistons and piston rods, etc. No limitations are imposed here.
[0065] Specifically, in this embodiment, the fixing part 3121 is a sleeve. In other embodiments, the fixing part 3121 is a linear bearing, etc. No limitation is made here.
[0066] Specifically, such as Figure 4 As shown, the first buffer 312 also includes a locking part 3124, which is connected to the buffer part 3122. Along the sliding direction of the buffer part 3122, the locking part 3124 and the elastic part 3123 are located on both sides of the fixed part 3121, and the locking part 3124 can abut against the fixed part 3121. The locking part 3124 can restrict the sliding of the buffer part 3122 in the fixed part 3121 along the first direction, and in particular, prevents the buffer part 3122 from dislodging from the fixed part 3121 due to the elastic force of the elastic part 3123 when the first clamping body 311 moves away from the product, thereby ensuring the stability and normal operation of the overall structure of the first buffer 312.
[0067] Specifically, such as Figure 4 As shown, in this embodiment, the outer wall of the buffer portion 3122 at the end furthest from the product has an annular groove, and the locking portion 3124 is engaged within the annular groove. This arrangement ensures that the buffer portion 3122 experiences uniform force in the circumferential direction, making the connection more stable. It should be noted that in this embodiment, the locking portion 3124 is an elastic retaining ring. In other embodiments, the outer wall of the buffer portion 3122 at the end furthest from the product has a through hole, and the locking portion 3124 is a cotter pin, etc. No limitations are imposed here.
[0068] Specifically, in this embodiment, two first buffer members 312 are provided, and the two first buffer members 312 are arranged parallel to each other and spaced apart along the second direction. In other embodiments, one, three, or four first buffer members 312 are provided, etc. No limitation is made here.
[0069] Optionally, such as Figure 2 and Figure 4 As shown, the second clamping assembly 32 includes a second clamping body 321 and a second buffer 322. The second clamping body 321 is slidably connected to the second body 12, and the second buffer 322 is disposed on the second clamping body 321. The second buffer 322 can clamp the product along a second direction. When the driving member 8 drives the first clamping body 311 to approach the product along the first direction, the linkage assembly will drive the second clamping body 321 to move synchronously along the second direction. The second buffer 322 disposed on the second clamping body 321 clamps the product. The second buffer 322 can provide a certain buffering capacity for clamping the product and avoid damage to the clamped product. It should be noted that in this embodiment, the second clamping body 321 is an L-shaped clamping block. In other embodiments, the second clamping body 321 is a square clamping block or a clamping plate, etc. No limitation is made here.
[0070] Specifically, such as Figure 4 As shown, the second buffer 322 has the same structure as the first buffer 312, and will not be described in detail here.
[0071] Optionally, such as Figure 5 As shown, the bidirectional clamping and positioning fixture also includes a first guide unit 5. The first guide unit 5 includes a first guide rail 51 and a first slider 52 that are slidably connected. The first guide rail 51 extends along a first direction. One of the first guide rail 51 and the first slider 52 is disposed on the fixture body 1, and the other is disposed on the first clamping assembly 31. The slidably connected first guide rail 51 and first slider 52 can provide precise guidance for the first clamping assembly 31 along the first direction, ensuring that it maintains a stable motion trajectory during movement.
[0072] Specifically, such as Figure 5 As shown, in this embodiment, the first guide rail 51 is disposed on the second body 12, and the first slider 52 is disposed on the first clamping body 311. In other embodiments, the first guide rail 51 is disposed on the first clamping body 311, and the first slider 52 is disposed on the second body 12, etc. No limitation is made here.
[0073] Specifically, in this embodiment, the first guide rail 51 is threaded to the second body 12, and the first slider 52 is threaded to the first clamping body 311. In other embodiments, the first guide rail 51 is bonded to the second body 12, and the first slider 52 is snapped to the first clamping body 311, etc. No limitations are imposed here.
[0074] Optionally, such as Figure 5 As shown, multiple first guide units 5 are provided, and these multiple first guide units 5 are arranged parallel to each other along a direction perpendicular to the first direction. The arrangement of multiple first guide units 5 can more stably constrain and guide the movement direction of the first clamping body 311, improving the overall structural stability and guiding accuracy. Specifically, in this embodiment, two first guide units 5 are provided, and these two first guide units 5 are arranged parallel to each other along the second direction. In other embodiments, two first guide units 5 are provided, and these two first guide units 5 are arranged parallel to each other along a third direction; or, three first guide units 5 are provided, and these three first guide units 5 are arranged parallel to each other along the second direction, etc. No limitation is made here.
