Description

Technical Field

[0001] This utility model relates to the field of positioning tooling technology, specifically a positioning tooling for machine frame processing. Background Technology

[0002] The frame is the main structure for the fixed installation of a machine. It bears the weight of the entire machine and plays a supporting and positioning role for the various components of the machine. All kinds of machines, equipment, and devices need a basic frame for support and fixation.

[0003] According to a positioning fixture for frame processing published in the public notice (Announcement No.: CN212946554U), after the adjustment is completed as described in the above application, the frame is placed on the top of the rotary table and clamped and positioned by the clamping claw. This fixture can be adjusted according to the shape and size of the frame and is applicable to frames of different shapes and sizes, with strong applicability.

[0004] However, in actual use, the frames of the aforementioned equipment are generally frame structures, and the frames of different machines have different and irregular shapes. Current positioning fixtures are generally only applicable to specific frames, have poor applicability, and are extremely inconvenient for positioning. In view of this, we propose a positioning fixture for frame processing. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for frame processing to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for machine frame processing, including a mounting base, a fixing frame snapped onto the upper surface of the mounting base, an adjusting plate detachably connected to the side wall of the fixing frame via bolts, a fixing mechanism disposed above the mounting base, and a promoting mechanism disposed above the mounting base, the fixing mechanism comprising:

[0007] An adjustment hole is provided on the side wall of the adjustment plate. A protrusion is fixedly installed on the side wall of the fixing frame. A support rod is fixedly installed on the side wall of the fixing frame. A movable groove is provided on the lower surface of the adjustment plate. An adjustment groove is provided on the side wall of the fixing frame. A threaded rod is threadedly connected to the surface of the adjustment plate.

[0008] A clamping plate is rotatably mounted on the end of a threaded rod. A stabilizing rod is fixedly mounted on the side wall of the clamping plate. A groove is provided on the side of the clamping plate away from the stabilizing rod. A stabilizing sleeve is fixedly mounted on the inner wall of the groove via a rotating shaft.

[0009] Preferably, the promoting mechanism includes a straight rod, which is fixedly mounted on the inner wall of the clamping plate. A torsion spring is fixedly connected to the arc surface of the straight rod, and the end of the torsion spring away from the clamping plate is fixedly connected to the inner wall of the support plate. A rubber ring is fixedly mounted on the surface of the support plate.

[0010] Preferably, the side wall of the pallet is provided with a rotating hole, the diameter of which is adapted to the diameter of the straight rod, and the pallet is sleeved on the arc surface of the straight rod, so that the pallet can rotate on the arc surface of the straight rod.

[0011] Preferably, the surface of the clamping plate is provided with a fixing groove, the shape of which is adapted to the shape of the straight rod, and the straight rod is fixedly installed on the inner wall of the fixing groove.

[0012] Preferably, the position of the support rod is at the same horizontal line as the movable groove, so that the adjusting plate can move through the support rod.

[0013] Preferably, the surface of the stabilizing sleeve is provided with a rubber threaded strip, which allows the clamping plate to fit better against the surface of the frame.

[0014] Preferably, the number of grooves is set to several, and the several grooves are arranged in a linear array on the surface of the clamping plate. Several stabilizing sleeves can be set in the several grooves to ensure the positioning of the frame.

[0015] Compared with the prior art, the present invention provides a positioning fixture for machine frame processing, which has the following advantages:

[0016] 1. This positioning fixture for machine frame processing has a fixing mechanism that clamps the fixing frame onto the surface of the mounting base. The position of the clamping plate is adjusted by adjusting the position of the adjusting plate. The support rod ensures the stability of the adjusting plate. The threaded rod is adjusted to clamp the clamping plate onto the surface of the machine frame. The rubber stabilizing sleeve fits better against the surface of the machine frame, thus conforming to the concave and convex surfaces of the machine frame and adapting to different models of machine frames.

[0017] 2. The positioning fixture for this frame processing is equipped with a facilitating mechanism. The support plate, in conjunction with the rubber ring, can lift the surface of the frame. Under the action of the torsion spring, the support plate rotates on the surface of the straight rod, thereby providing a lifting or auxiliary fixing effect on the lower end of the frame.

[0025] In addition, the promoting mechanism 4 includes a straight rod 401, which is fixedly mounted on the inner wall of the clamping plate 309. A torsion spring 402 is fixedly connected to the arc surface of the straight rod 401. The end of the torsion spring 402 away from the clamping plate 309 is fixedly connected to the inner wall of the support plate 403. A rubber ring 404 is fixedly mounted on the surface of the support plate 403. A rotating hole is opened on the side wall of the support plate 403. The diameter of the rotating hole is adapted to the diameter of the straight rod 401. The support plate 403 is sleeved on the arc surface of the straight rod 401, so that the support plate 403 can rotate on the arc surface of the straight rod 401.

[0026] In this embodiment of the utility model, a fixing groove is provided on the surface of the clamping plate 309. The shape of the fixing groove is adapted to the shape of the straight rod 401. The straight rod 401 is fixedly installed on the inner wall of the fixing groove.

The surface of the stabilizing sleeve 310 is provided with a rubber threaded band. The rubber threaded band makes the clamping plate 309 fit better against the surface of the frame. A number of grooves 308 are provided. The grooves 308 are arranged in a linear array on the surface of the clamping plate 309.
