Description

Technical Field

[0001] This utility model belongs to the field of workpiece processing, and specifically relates to a workpiece outer diameter machining positioning fixture. Background Technology

[0002] A workpiece outer diameter machining positioning fixture is a specialized device used to fix the outer diameter of a workpiece during machining, ensuring its positional accuracy and machining stability. It improves machining accuracy, efficiency, and quality by restricting the workpiece's degrees of freedom, thus maintaining its correct machining position under the machine tool or cutting tool.

[0003] Existing workpiece outer diameter machining positioning fixtures are designed with manual angle adjustment capabilities, allowing operators to adjust the angle according to actual machining needs. However, the current angle adjustment process mainly relies on the operator's subjective visual observation and experience judgment, lacking a precise quantitative feedback mechanism, which makes it impossible to achieve visualization and precise control of the angle adjustment amount.

[0004] In view of this, the present invention provides a workpiece outer diameter machining positioning fixture to solve the problem of not being able to achieve visual adjustment of the angle adjustment amount. Utility Model Content

[0005] To achieve the above objectives, the present invention provides the following technical solution: a workpiece outer diameter machining positioning fixture, comprising: a housing, a rotating assembly installed inside the housing and extending to the outside, wherein a clamping assembly for fixing the workpiece to be machined is mounted on the side surface of the rotating assembly;

[0006] The rotating assembly includes a micrometer mounted on the side surface of the housing and extending into the interior, a first drive unit connected to the output end of the micrometer, a rotary seat connected to the output end of the first drive unit, and a side plate connected to the side surface of the rotary seat.

[0007] The clamping assembly includes a clamping base mounted on the surface of the side plate, a second drive unit mounted inside the clamping base and extending to the outside, a clamping block connected to the output end of the second drive unit, and a guide unit connected between the clamping block and the clamping base.

[0008] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the first driving part includes a worm gear connected to the output end of the micrometer, a first bearing sleeved on the end of the worm gear and fitted into the inner wall of the housing, a second bearing fitted into the side surface of the housing, a first rotating rod penetrating the interior of the second bearing and connected to the rotating seat, and a worm wheel connected to the surface of the first rotating rod and meshing with the worm gear.

[0009] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the second driving unit includes an adjustment mechanism installed on the side surface of the clamping base and connected to two clamping blocks, and a driving mechanism installed inside the clamping base and connected to the adjustment mechanism.

[0010] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the adjustment mechanism includes a third bearing fitted and mounted on the side surface of the clamping base, a second rotating rod that passes through and is connected inside the third bearing, a gear plate connected to the end of the second rotating rod, and racks that are respectively connected to the side surfaces of the two sets of clamping blocks and mesh with the gear plate.

[0011] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the two racks are arranged in a centrally symmetrical manner with the central axis of the gear disk as the circle.

[0012] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the driving mechanism includes a driven bevel gear connected to the end of the second rotating rod, a drive motor installed on the inner wall of the clamping base, and an active bevel gear connected to the output end of the drive motor and meshing with the driven bevel gear.

[0013] As a preferred embodiment of the workpiece outer diameter machining positioning fixture of this utility model, the guide part includes a guide rail connected to the side surface of the clamping base and guide grooves respectively opened on the side surfaces of two sets of clamping blocks and adapted to the size of the guide rail.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, when the micrometer head rotates, it drives the worm gear to rotate. When the worm gear rotates, it drives the first rotating rod to rotate through the worm wheel. When the first rotating rod rotates, it drives the rotating seat to rotate. When the rotating seat rotates, it drives the clamping assembly to rotate through the side plate. The surface of the micrometer head is provided with a scale, through which the adjustment amount of each rotation can be observed, thereby achieving precise adjustment of the rotation angle.

[0016] This invention utilizes a drive motor to rotate an active bevel gear, which in turn drives a second rotating rod to rotate. The second rotating rod then drives a gear disc to rotate. When the gear disc rotates, it can cause two racks to move in opposite directions. This allows the two racks to drive two clamping blocks to move in opposite directions, thus enabling the positioning of the workpiece's outer diameter during machining. The invention is simple in structure and easy to use. Attached Figure Description

When the first rotating rod 224 rotates, it can drive the rotating seat 23 to rotate. The surface of the micrometer head 21 is provided with a scale, through which the adjustment amount of each rotation can be observed, thereby achieving precise adjustment of the rotation angle.

[0029] Furthermore, the second drive unit 32 includes an adjustment mechanism 321 installed on the side surface of the clamping base 31 and connected to the two clamping blocks 33, and a drive mechanism 322 installed inside the clamping base 31 and connected to the adjustment mechanism 321.
