Technical Field
[0001] This utility model relates to the field of mechanical parts manufacturing technology, specifically to an end cap integrated processing fixture. Background Technology
[0002] Currently, the end caps require machining different surfaces and different machining fixtures. The end caps have high machining accuracy requirements, and frequent fixture changes and workpiece assembly / disassembly will affect machining efficiency and accuracy. Therefore, it is necessary to redesign a set of fixtures to complete the comprehensive machining of different processes and different machined surfaces of the end caps. Utility Model Content
[0003] The purpose of this utility model is to provide an end cap integrated machining fixture to improve machining efficiency and ensure product machining accuracy.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A comprehensive machining fixture for end caps includes a base plate. A first positioning post is vertically arranged at one end of the top of the base plate for positioning the end cap and machining its surface A. A hand screw seat is provided on one side of the base plate of the first positioning post, and a hand screw is screwed onto the hand screw seat for fixing the end cap in conjunction with the first positioning post. A vertical plate is provided on the other side of the top of the base plate, and a second positioning post and a diamond-shaped pin are vertically arranged on the front side of the vertical plate for positioning the end cap and machining its surface B.
[0006] Preferably, there are two of each of the first and second positioning posts, and two of each of the hand-tightening screws and diamond pins that cooperate with them, for processing two end caps at once.
[0007] Preferably, a double-ended screw is screwed onto the base plate between the two first positioning posts, and a pressure plate is fixed to the top of the double-ended screw with a second nut. A double-ended screw is also screwed onto the vertical plate between the two second positioning posts, and a pressure plate is fixed to the front end of the double-ended screw with a second nut, which is used to press down the end cap to be processed.
[0008] Preferably, the first positioning post is fixedly connected to the base plate by the second screw, and the rear end of the second positioning post is provided with an external thread and passes through the rear end of the vertical plate and is fixed by the second nut and washer assembly, which facilitates the replacement of the first and second positioning posts that have been worn for a long time to ensure positioning accuracy.
[0009] Preferably, the double-ended screw is fitted with a spring to prevent the end cap from being crushed.
[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model adopts a multi-station clamping and multi-process processing method. One set of fixtures can process different planes of the workpiece and complete the processing of multiple processes of the workpiece. The fixture utilization rate is high, the processing efficiency is improved, and the influence of the end cap blank face on positioning is effectively avoided. The fixtures do not need to be changed frequently, ensuring the processing accuracy. Attached Figure Description

[0014] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0016] like Figure 1 and Figure 2 As shown, this embodiment of the utility model includes a base plate 1. A first positioning post 6 is vertically arranged at one end of the top of the base plate 1 for positioning the end cap 17 to be machined on its surface A. A hand screw seat 4 is arranged on the base plate 1 on one side of the first positioning post 6, and a hand screw 2 is screwed onto the hand screw seat 4 for cooperating with the first positioning post 6 to fix the end cap 17. A vertical plate 8 is arranged on the other side of the top of the base plate 1. A second positioning post 12 and a diamond pin 11 are vertically arranged on the front side of the vertical plate 8 for positioning the end cap 17 to be machined on its surface B.
[0017] There are two first positioning posts 6 and two second positioning posts 12, and two hand-turning screws 2 and two diamond pins 11 that cooperate with them, for processing two end caps 17 at one time.
[0018] A double-ended screw 16 is screwed onto the base plate 1 between the two first positioning posts 6. A pressure plate 13 is fixed to the top of the double-ended screw 16 with a second nut 15. A double-ended screw 16 is also screwed onto the vertical plate 8 between the two second positioning posts 12. A pressure plate 13 is fixed to the front end of the double-ended screw 16 with a second nut 15, which is used to press down the end cap 17 to be processed.
[0019] Place the end caps 17 in the two stations on the left side of the base plate 1, and fix them with the first positioning pin 6 and the hand screw 2. Then, rotate the pressure plate 13 with the double-headed screw 16 to press the end caps 17, and process the plane A on the end caps 17. After processing, take out the two end caps 17 and install them in the two stations on the right side of the base plate 1. The right station is positioned by the diamond pin 11 and the second positioning pin 12. The pressure plate 13 presses the end caps 17 to process another plane B. After processing, the end caps 17 can be removed. Repeat this process. Two end caps can be completed in one clamping.
