Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing technology, specifically to an automotive powertrain positioning fixture that facilitates position adjustment. Background Technology

[0002] Automotive powertrain positioning fixtures are specialized tools or equipment used to accurately position and fix various components of an automotive powertrain during assembly, repair, or testing. A powertrain generally includes an engine, transmission, and related transmission system components. The main function of this fixture is to ensure that these components maintain the correct position and angle during installation or maintenance to ensure the normal operation of the entire system.

[0003] For example, the patent document with announcement number CN221248755 U describes a precision positioning fixture for an automotive powertrain. The described solution is as follows: a first gear is set inside the top of a fixed table. A first rotary motor drives the first gear to rotate, which in turn drives a rack inside a movable seat to move. This allows the movable seat to move laterally between the positioning seat and the top of the automotive engine block. Simultaneously, a second rotary motor inside the movable seat starts, which drives a one-way threaded rod to rotate. The first threaded blocks on both sides of the one-way threaded rod can then drive the positioning seat to move longitudinally through a first connecting block. Through the cooperation between the movable seat and the positioning seat, the position of the top of the positioning seat can be freely adjusted, thereby improving the flexibility and convenience of using the precision positioning fixture for the automotive powertrain.

[0004] In the above cases, the workpiece can only be clamped manually, which is time-consuming and labor-intensive in the long run. In addition, the worktable is difficult to raise or lower, and it cannot meet various work requirements. Utility Model Content

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In one embodiment, such as Figures 1-4As shown, a positioning fixture for an automotive powertrain, facilitating position adjustment, includes: a base plate 100, a top plate 200, a worktable 300, and a clamping assembly. The top plate 200 is positioned above the base plate 100, and the worktable 300 is rotatably connected to the top of the top plate 200. The clamping assembly includes a sliding groove 401, which is located on the top of the worktable 300. A bidirectional lead screw 402 is rotatably connected inside the sliding groove 401, and a limiting rod is also provided inside the sliding groove 401. 403, the two ends of the bidirectional lead screw 402 are threadedly connected to clamping plates 404, the outer wall of the limiting rod 403 is slidably connected to the clamping plate 404, the clamping plate 404 is slidably connected to the top of the worktable 300, and a driving assembly for driving the bidirectional lead screw 402 is provided on one side of the worktable 300; by rotating the bidirectional lead screw 402, the two clamping plates 404 are driven to clamp each other, and the movement direction of the clamping plates 404 is guided and limited by the limiting rod 403 and the sliding groove 401.

[0029] In one embodiment, such as Figure 4 As shown, the drive assembly includes a support block 501, which is disposed on one side of the worktable 300. A first gear 502 is fixedly connected to one end of the bidirectional lead screw 402 near the support block 501. A movable plate 503 is slidably connected inside the support block 501. A handle 504 and a first motor 505 are respectively provided at both ends of one side of the movable plate 503. A connecting column is fixedly connected to the output end of the first motor 505 and one end of the handle 504. A second gear 506 and a third gear 507 are respectively provided on the two connecting columns. A support plate 508 is also provided on one side of the worktable 300. An electric push rod 509 is mounted on one side of the support plate 508. The output end of the push rod 509 is fixedly connected to the movable plate 503. By starting the electric push rod 509, the movable plate 503 is moved, and the position of the handle 504 and the first motor 505 is adjusted by the movable plate 503. When the third gear 507 on the first motor 505 meshes with the first gear 502, the first motor 505 can be started to drive the third gear 507 to rotate, and drive the first gear 502 to rotate, thereby causing the bidirectional lead screw 402 to rotate. When it is necessary to manually rotate the bidirectional lead screw 402, the movable plate 503 is moved to make the second gear 506 mesh with the first gear 502, and the handle 504 is rotated, thereby causing the bidirectional lead screw 402 to rotate.

[0030] In one embodiment, such as Figure 4As shown, the first gear 502 meshes with the second gear 506, and the first gear 502 meshes with the third gear 507. By meshing the first gear 502 with the second gear 506 and the third gear 507 respectively, the rotation mode of the bidirectional lead screw 402 can be changed, making it easier to switch between automatic and manual drive modes, thus improving its usability.

[0031] In one embodiment, such as Figure 1 and 2 As shown, the lifting assembly includes a fixed column 601, with both ends of the fixed column 601 fixedly connected to the interior of the base plate 100 and the interior of the top plate 200. An electric telescopic rod 602 is installed on the outer wall of the fixed column 601, and a movable column 603 is fixedly connected to the output end of the electric telescopic rod 602. A scissor lift 604 is installed on the fixed column 601 and the movable column 603. The top plate 200 and the base plate 100 are provided with a sliding groove 605 corresponding to the position of the movable column 603. The movable column 603 is slidably connected to the interior of the sliding groove 605. By activating the electric telescopic rod 602, the movable column 603 is moved within the sliding groove 605, thereby causing the scissor lift 604 to rise and fall.

[0032] In one embodiment, such as Figure 1 As shown, the base plate 100 is equipped with casters around its perimeter, and the top plate 200 is equipped with handles on both sides; the casters facilitate the movement of the base plate 100.

[0033] In one embodiment, such as Figure 2 As shown, a geared motor 701 is installed on the inner top wall of the top plate 200. The output end of the geared motor 701 passes through the top plate 200 and is fixedly connected to the worktable 300. By starting the geared motor 701, the worktable 300 is driven to rotate.

[0034] In one embodiment, such as Figure 1 and 3 As shown, the two clamping plates 404 clamp the workpiece facing each other; the workpiece is fixed by the clamping plates 404.

[0035] The above embodiments disclose an automotive powertrain positioning fixture that facilitates position adjustment. First, the workpiece is placed on the worktable 300. Then, by activating the electric push rod 509, the moving plate 503 is moved. The moving plate 503 then adjusts the positions of the handle 504 and the first motor 505. When the third gear 507 on the first motor 505 meshes with the first gear 502, activating the first motor 505 rotates the third gear 507, which in turn rotates the first gear 502. This causes the bidirectional lead screw 402 to rotate. When manual adjustment is needed... When the bidirectional lead screw 402 is rotated, the moving plate 503 is moved to make the second gear 506 mesh with the first gear 502, and the handle 504 is turned, thereby causing the bidirectional lead screw 402 to rotate. After the bidirectional lead screw 402 rotates, it drives the two clamping plates 404 to clamp the workpiece in opposite directions. The workpiece is fixed by the clamping plates 404. At this time, the electric telescopic rod 602 can be activated to drive the moving column 603 to move inside the slide groove 605, thereby causing the scissor lift 604 to rise and fall, thereby adjusting the height of the worktable 300 to facilitate working at different heights.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
