AI Technical Summary
The existing grinders that do not process chamfered parts have problems such as wasting time, and the chamfer size and length cannot be limited, resulting in low processing efficiency and poor product quality.
A grinding fixture including beveled edges, grinding grooves, chamfering mouths and part placement grooves is designed to achieve precise chamfering through beveled edges and grinding grooves. The part placement grooves and chamfering mouths ensure the correct position and size of the chamfering edges.
The processing efficiency is improved, and the average working time for processing a chamfer is shortened to 30 seconds, which improves the efficiency by about 40%. At the same time, the chamfers of the parts are consistent in size and good in quality, and are suitable for parts of different sizes and types.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grinding machine processing fixtures, in particular to a fixture for processing non-through chamfer parts on a grinding machine. Background Technique
[0002] Many existing part products need to be processed with a one-sided non-through chamfer 1. As Figure 1 shown, the non-through chamfer means that the one-sided chamfer does not reach the bottom. Existing fixtures for processing non-through chamfer parts on a grinding machine, as Figure 2 shown, usually adopt a V-shaped iron 2. The part 3 is placed in the V-shaped groove of the V-shaped iron for positioning, and then the one-sided chamfer 4 is processed by a grinding head. There are the following disadvantages when using this fixture to process non-through chamfer parts:
[0003] 1. Due to factors such as different sizes and special shapes of the processed parts, some workpieces are not suitable for clamping due to objective conditions such as the V-shaped iron, and it is time-consuming to process.
[0004] 2. When processing the chamfer in this way, the size of the chamfer cannot be limited, which requires high requirements for chamfering technicians and makes the chamfering process more complicated.
[0005] 3. When processing the non-through chamfer in this way, the length of the chamfer cannot be limited, and the chamfering process is more complicated. Content of the Utility Model
[0006] To solve the above technical problems, the utility model designs a fixture for processing non-through chamfer parts on a grinding machine.
[0007] The utility model adopts the following technical scheme:
[0008] A fixture for processing non-through chamfer parts on a grinding machine, including a fixture body. A bevel edge is provided on the fixture body. A grinding groove is arranged along the bevel edge on the bevel edge of the fixture body. A chamfer opening is horizontally opened on the bevel edge of the fixture body. A part placement groove is arranged corresponding to the lower part of the chamfer opening on the fixture body. The part is placed in the part placement groove, and the chamfered edge to be processed of the part protrudes from the chamfer opening.
[0009] Preferably, a dimension is arranged along the chamfer opening on the fixture body. The length of the one-sided processed chamfer can be accurately determined according to the dimension.
[0010] Preferably, the fixture body is in the shape of a right triangle.
[0011] Preferably, the part placement groove is in the shape of a right triangle, and the chamfer opening is arranged at the right angle position. It is convenient for the chamfered edge to be processed of the part to protrude from the chamfer opening.
[0012] Preferably, positioning and installation holes are opened on the fixture body. It is convenient to install and fix the fixture body.
[0013] The beneficial effects of the present utility model are as follows: (1) The jig of the present utility model is small in size and convenient to use. When chamfering a workpiece by hand on the jig, there is no need for clamping, which improves the processing efficiency. When using this jig to process a blind chamfer, the average working hour for processing one chamfer is 30 seconds, and the efficiency is increased by about 40%; (2) During the process of machining parts, after setting the gap between the grinding wheel and the jig, the chamfers of the machined parts are of the same size, and the quality of the parts is good; (3) The jig has strong versatility, can meet the processing of blind chamfer parts in batches on site, can quickly process parts with different types of chamfers, and is applicable to parts of different sizes and special shapes.

[0019] The technical solutions of the present utility model will be further specifically described below through specific embodiments in conjunction with the accompanying drawings:
[0020] Embodiment: As Figure 3 shown, a jig for machining blind chamfer parts on a grinding machine includes a jig body 5. A bevel edge is provided on the jig body. A grinding groove 6 is arranged along the bevel edge on the bevel edge of the jig body. A chamfer opening 7 is horizontally opened on the bevel edge of the jig body. A part placement groove 8 is provided on the jig body corresponding to the lower part of the chamfer opening. The part is placed in the part placement groove, and the chamfered edge of the part to be machined protrudes from the chamfer opening.
[0021] Dimensions are arranged along the chamfer opening on the jig body. The jig body is in the shape of a right triangle. The part placement groove is in the shape of a right triangle, and the chamfer opening is arranged at the right angle position. Positioning and mounting holes 9 are opened on the jig body. It is convenient to install and fix the jig body.
[0022] As Figure 4 shown, when the present utility model is in use, after setting the gap between the grinding wheel 10 and the jig, the chamfers of the machined parts are of the same size, and the quality of the parts is good.
[0023] The utility model has a small volume and is convenient to use. When chamfering a workpiece by hand on the jig, clamping is not required, which improves the processing efficiency. When using this jig to process blind chamfers, the average working hours for processing one chamfer is 30 seconds, and the efficiency is increased by about 40%. The jig has strong versatility and can meet the processing of blind chamfer parts in batches on site. It can quickly process parts with different types of chamfers and is applicable to parts of different sizes and special shapes.
[0024] The above embodiments are only a preferred solution of the utility model, and do not impose any form of limitation on the utility model. There are other variations and modifications without exceeding the technical solutions recorded in the claims.
