Description

Technical Field

[0001] This utility model relates to the field of sensor assembly technology, and in particular to a sensor component positioning and clamping fixture. Background Technology

[0002] Sensor component positioning and clamping fixtures are devices used to fix and position sensors, typically during sensor testing, processing, or installation.

[0003] Due to the differences between the styles of different sensor components, when a general-purpose clamping fixture is used for different types of sensor components, the positioning clamping fixture may not be able to clamp and position the different types of sensor components well. This may cause the sensor components to shift during subsequent processing and affect the processing effect of the sensor components. Utility Model Content

[0004] In view of this, the present invention addresses the deficiencies of the existing technology and its main objective is to provide a sensor component positioning and clamping fixture. This fixture solves the problem that when different types of sensor components are all using a general-purpose clamping fixture, the positioning and clamping fixture sometimes cannot effectively clamp and position different types of sensor components, which may cause the sensor components to shift during subsequent processing and affect the processing effect of the sensor components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a sensor component positioning and clamping fixture, including a worktable and a mold core disposed on the worktable, wherein a workpiece is placed on the mold core, characterized in that: a drive cylinder is provided at the lower part of the worktable, and the output shaft of the drive cylinder passes through the mold core and is connected to a limit component; During operation, the output shaft moves from the bottom to the top of the worktable, causing the overlapping part in the limiting assembly to unfold and overlap the top of the workpiece.

[0006] Furthermore, the mold core has a channel in the middle that runs through the worktable, and the output shaft is located in the channel; during operation, the limiting component moves out from the top of the channel, and when changing workpieces, the limiting component is stored in the channel.

[0007] Furthermore, the mold core includes a template adapted to the workpiece, and a protrusion on the template adapted to the inner cavity of the workpiece, with the channel located in the middle of the protrusion.

[0008] Furthermore, the channel includes a first section that runs through the workbench and the mold core, and a second section that connects to the top of the workbench and the first section, with a limiting component located within the second section.

[0009] Furthermore, the limiting assembly includes a base installed in the second part, and traction members disposed on both sides of the opening on the base. The overlapping part contains two members and is movably connected to the two traction members and the output shaft respectively.

[0010] Furthermore, the traction component includes mounting seats installed on both sides of the opening, and connecting pieces that movably connect to the mounting seats, with the connecting pieces movably connected to the overlapping portion.

[0011] Furthermore, the overlapping portion includes an overlapping plate and an overlapping frame connected to the overlapping plate, the overlapping frame being concave and clamping the connecting piece.

[0012] Furthermore, the overlapping frame is provided with a first connecting rod and a second connecting rod, the connecting piece is sleeved on the first connecting rod, and the output shaft is sleeved on the second connecting rod.

[0013] Furthermore, the top of the output shaft is located between the two connecting pieces, and the opposite sides of the two connecting pieces are provided with arc-shaped openings, with the two sides of the top of the output shaft respectively matching the two arc-shaped openings.

[0014] Furthermore, the output shaft includes a shaft body and an extrusion plate connected to the upper end of the shaft body. The extrusion plate is held by an overlap bracket, and the extrusion plate is parallel to the side of the connecting plate.

[0015] Compared with the prior art, this utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, the workpiece placed on the mold core is clamped by using a drive cylinder to drive the limiting component to move, so as to avoid the workpiece shifting in subsequent processing. In addition, since the drive cylinder is located below the worktable, it can avoid obstructing the view of the operator in subsequent processing, making it more convenient for the operator to process the workpiece.

[0016] To more clearly illustrate the structural features and effects of this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description

Detailed Implementation

[0022] Please refer to Figure 1-4 As shown, it illustrates the specific structure of a preferred first embodiment of the present invention, which is a sensor component positioning and clamping fixture, including a worktable 10 and a mold core 20 disposed on the worktable 10, on which a workpiece 30 is placed. The feature is that a drive cylinder 40 is provided at the lower part of the worktable 10, and the output shaft 41 of the drive cylinder 40 passes through the mold core 20 and is connected to a limit assembly 50. During operation, the output shaft 41 moves from the bottom to the top of the worktable 10, causing the overlapping portion 51 in the limiting assembly 50 to unfold and overlap the top of the workpiece 30. Compared to existing sensor component positioning and clamping fixtures, which use a drive cylinder located above the sensor component to drive the extruder for universal clamping and positioning of the workpiece, this sensor component positioning and clamping fixture uses a drive cylinder 40 to drive the limiting assembly 50 to move and clamp the workpiece 30 placed on the mold core 20. This prevents the workpiece 30 from shifting during subsequent processing. In addition, because the drive cylinder 40 is located below the worktable 10, it avoids obstructing the operator's view during subsequent processing, making it easier for the operator to process the workpiece 30.

[0023] like Figure 1 As shown, for example, the mold core 20 has a channel 11 that passes through the worktable 10 in the middle, and the output shaft 41 is located in the channel 11. During operation, the limiting component 50 moves out from the top of the channel 11. When changing the workpiece 30, the limiting component 50 is stored in the channel 11. The mold core 20 is installed on the upper end face of the worktable 10, and the drive cylinder 40 is installed on the lower end face of the worktable 10. The workpiece 30 is placed on the mold core 20. In order for the drive cylinder 40 to drive the limiting component 50 to clamp the workpiece 30 on the mold core 20, a channel 11 that passes through the worktable 10 is opened in the middle of the mold core 20, and the output shaft 41 of the drive cylinder 40 extends into the channel 11 and connects with the limiting component 50 located in the channel 11. This allows the operator to activate the drive cylinder 40 to push the overlapping part 512 in the limiting component 50 to unfold and overlap the workpiece 30 on the mold core 20.

[0024] like Figure 1As shown, exemplarily, the mold core 20 includes a template 21 adapted to the workpiece 30, and a protrusion 22 on the template 21 adapted to the inner cavity of the workpiece 30, with the channel 11 located in the middle of the protrusion 22. When the template 21 is adapted to the workpiece 30, it can prevent bending deformation of a part of the workpiece 30 due to the gap between the workpiece 30 and the template 21 when the workpiece 30 is squeezed by the overlapping part 51. The protrusion 22 adapted to the shape of the inner cavity of the workpiece 30 can further ensure the stability of the workpiece 30 when placed on the mold core 20.

[0025] like Figure 2 As shown, exemplarily, the channel 11 includes a first portion 111 penetrating the worktable 10 and the mold core 20, and a second portion 112 communicating with the top of the worktable 10 and the first portion 111. A limiting component 50 is disposed within the second portion 112. Because the limiting component 50 is disposed within the channel 11, to prevent the limiting component 50 from falling out of the channel 11 unnecessarily, the channel 11 is divided into the first portion 111 and the second portion 112. The diameter of the second portion 112 is larger than that of the first portion 111, so that the limiting component 50 placed within the second portion 112 is effectively supported.

[0026] like Figure 3 As shown, exemplarily, the limiting component 50 includes a base 52 installed within the second part 112, and traction members 53 opposite to each other on both sides of the opening 54 on the base 52. The overlapping portion 51 contains two parts and is movably connected to the two traction members 53 and the output shaft 41, respectively. The base 52 is adapted to the second part 112, and the center of the base 52 has an opening 54 for the output shaft 41 to pass through. When the output shaft 41 passes through the opening 54, it connects with the overlapping portion 51 installed on the traction member 53. When the output shaft 41 moves towards the upper end face of the worktable 10, the pressure of the output shaft 41 on the overlapping portion 51 causes the overlapping portion 51 to move towards the top of the channel 11 and unfold to overlap the workpiece 30 on the mold core 20 through the linkage with the traction member 53.

[0027] like Figure 3 As shown, exemplarily, the traction member 53 includes mounting seats 531 installed on both sides of the opening 54, and a connecting piece 532 movably connected to the mounting seats 531. The connecting piece 532 is movably connected to the overlapping portion 51. The movable connection between the connecting piece 532, the overlapping portion 51, and the mounting seat 531 allows the overlapping portion 51 connected to the connecting piece 532 to be displaced around the mounting seat 531.

[0028] Specifically, the mounting base 531 includes two oppositely arranged fixing blocks 5311 located on one side of the opening 54, a third connecting rod 5312 inserted between the two fixing blocks 5311, and a connecting piece 532 sleeved on the third connecting rod 5312.

[0029] In this embodiment, as the output shaft 41 is pressed, the connecting piece 532 moves around the third connecting rod 5312, changing from an inclined state to a vertical state, so that the overlapping part 51 moves up to the top of the channel 11, allowing the unfolded overlapping part 51 to overlap the workpiece 30 on the upper end face mold core 20 of the workbench 10.

[0030] like Figure 4 As shown, exemplarily, the overlapping portion 51 includes an overlapping plate 511 and an overlapping frame 512 connected to the overlapping plate 511. The overlapping frame 512 is concave and clamps the connecting piece 532. The overlapping plate 511 is used to overlap the workpiece 30, and the overlapping frame 512 is connected to the connecting piece 532 and the output shaft 41. When the overlapping frame 512 is concave, the connecting piece 532 and the output shaft 41 are both located in the open inner cavity of the overlapping frame 512. In addition, the connecting piece 532 is located above the output shaft 41, so that when the output shaft 41 is upward, it can squeeze the connecting piece 532 to move around the third connecting rod 5312 and push the overlapping frame 512 to move upward.

[0031] Specifically, the overlapping frame 512 is provided with a first connecting rod 513 and a second connecting rod 514. The connecting piece 532 is sleeved on the first connecting rod 513, and the output shaft 41 is sleeved on the second connecting rod 514. The first connecting rod 513 is located above the second connecting rod 514. This design allows the upward movement of the output shaft 41 to push the connecting piece 532 upward, and the overlapping frame 512 unfolds under the pressure of the output shaft 41 to overlap the workpiece 30.

[0032] like Figure 4 As shown, for example, the top of the output shaft 41 is located between the two connecting pieces 532, and the two connecting pieces 532 have arc-shaped openings 533 on opposite sides. The two sides of the top of the output shaft 41 are respectively adapted to the two arc-shaped openings 533. Through the design of the arc-shaped openings 533 on the connecting pieces 532, and the adaptation of the output shaft 41 to the arc-shaped openings 533, when the output shaft 41 moves upward, the connecting pieces 532 can more easily change from an inclined state to a vertical state and lift the overlapping frame 511.

[0033] like Figure 4 As shown, exemplarily, the output shaft 41 includes a shaft body 411 and an extrusion plate 412 connected to the upper end of the shaft body 411. The overlapping bracket 512 clamps the extrusion plate 412, and the extrusion plate 412 is parallel to the side of the connecting plate 532. To facilitate the insertion of the output shaft 41 into the overlapping bracket 512, the output shaft 41 is divided into a shaft body 411 connected to the drive cylinder 40 and an extrusion plate 412 away from the drive cylinder 40. The thickness of the extrusion plate 412 is the same as that of the moving plate 532 to ensure the stability of the overlapping bracket 512 after clamping the extrusion plate 412 and the moving plate 532.

[0034] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
