Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fixture positioning, and particularly relates to a workpiece positioning device for a hydraulic fixture. Background Art
[0002] In the mechanical processing industry, workpieces need to be positioned during the processing process to achieve consistency in repeated clamping. When the existing fixture positions the workpiece, the positioning pins on the fixture need to enter the positioning pin holes on the workpiece and contact and cooperate with each other to form positioning. During the descent of the fixture plate, when the positioning pins enter the holes for positioning, due to various deviations, it is difficult for the positioning pins to enter the holes, and they will inevitably contact with the positioning pins, causing scratches and scratches. The scratches and scratches of the positioning pin holes will affect the positioning of subsequent processes, causing a series of adverse consequences. With the rapid development of new technologies, the performance requirements of new energy and general vehicles are increasing, and the processing accuracy of automotive parts is also increasing. Therefore, it is necessary to take important measures to improve the positioning accuracy during product processing to avoid affecting the processing accuracy due to scratches and scratches on the positioning pin holes. Utility Model Content
[0003] In order to make up for the deficiencies of the prior art, the utility model provides a workpiece positioning device for a hydraulic clamp, which can position smoothly and quickly and avoid damaging the workpiece.
[0004] The utility model is realized through the following technical solutions:
[0005] A workpiece positioning device for a hydraulic clamp comprises a positioning support seat, on which a clamp support plate is provided, and is characterized in that a positioning round pin and a positioning diamond pin are provided on both sides of the clamp support plate, respectively, a round pin guide portion with a length of 10 mm and a guide angle of 30° is provided on the top of the positioning round pin, and a diamond pin guide portion with a length of 10 mm and a guide angle of 30° is provided on the top of the positioning diamond pin.
[0006] The beneficial effects of the utility model are: sufficient clearance and guide are provided to guide the positioning pin hole of the workpiece to quickly and smoothly enter the positioning pin, thereby avoiding scratches and marks on the positioning pin hole, achieving good positioning, and thus improving product quality. BRIEF DESCRIPTION OF THE DRAWINGS
[0007] The utility model is further described below in conjunction with the accompanying drawings.
[0008] Attached Figure 1 It is a structural schematic diagram of the utility model;
[0009] Attached Figure 2 This is a schematic diagram of the positioning round pin structure of the utility model;
[0010] Attached Figure 3 This is a schematic diagram of the positioning diamond pin structure of the utility model;
[0011] In the figure, 1 is a positioning support seat, 2 is a fixture support plate, 3 is a positioning round pin, 4 is a positioning diamond pin, 5 is a round pin guide part, and 6 is a diamond pin guide part. DETAILED DESCRIPTION
[0012] The attached figure shows a specific embodiment of the utility model. The embodiment comprises a positioning support seat 1, a fixture support plate 2 is arranged on the positioning support seat 1, a positioning round pin 3 and a positioning diamond pin 4 are arranged on both sides of the fixture support plate 2, a round pin guide portion 5 with a length of 10 mm and a guide angle of 30° is arranged on the top of the positioning round pin 3, and a diamond pin guide portion 6 with a length of 10 mm and a guide angle of 30° is arranged on the top of the positioning diamond pin 4.
[0013] By adopting the workpiece positioning device for the hydraulic clamp of the utility model, after the workpiece is pushed into the clamp support plate 2, the clamp support plate 2 will fall, and the positioning round pin 3 and the positioning diamond pin 4 on the clamp will enter the positioning pin hole on the workpiece, and the guiding length of the round pin guide part 5 and the diamond pin guide part 6 will be lengthened to 10 mm, and the guiding angle will be inclined to 30 degrees, so that during the descending process of the clamp support plate 2, there will be enough clearance and guide to guide the workpiece positioning pin hole into the positioning pin and the pin can be smoothly inserted. When the workpiece is successfully inserted, the inner wall of the pin hole can be avoided from being crushed after the clamp performs the clamping action, thereby achieving good positioning and ensuring the processing quality of the workpiece.
