Description

Technical Field

[0001] The utility model relates to the technical field of knife processing, in particular to a device for grinding PCD outer arcs. Background Art

[0002] The rotary cutter head is a tool for machining the thread groove of carbide (PCD rotary cutter) or high-speed steel roll (CBN or carbide rotary cutter).

[0003] like Figure 1 As shown in the rotary cutting head, the existing rotary cutting head production usually adopts the wire cutting method to Figure 1 The outer arc at A in the middle is processed and produced. However, due to the high requirements for the outer circle size accuracy and surface roughness of the outer circle of the rotary cutter head product, ordinary wire cutting equipment cannot meet the accuracy and roughness requirements. The existing production uses high-precision wire cutting equipment, but high-precision wire cutting equipment is expensive and cannot efficiently produce rotary cutter heads. At the same time, a bulge will be formed when the high-precision wire cutting equipment is cut, which requires secondary processing. Utility Model Content

[0004] The utility model aims to solve the problem of producing a rotary cutting tool head by conventional means and provide a device for grinding the outer arc of PCD.

[0005] A device for grinding PCD outer arc, comprising:

[0008] Furthermore, anti-slip patterns are provided on both end surfaces of the fixing groove.

[0009] Furthermore, the slot is configured to be in an arc shape; the bottom of the slot is flush with the bottom surface of the fixing slot.

[0010] Furthermore, conversion sleeves are provided at both ends of the fixing rod; the conversion sleeves are buckled on the ends of the fixing rod.

[0011] Furthermore, first threaded holes are formed through both ends of the fixing rod; second threaded holes corresponding to the first threaded holes are formed on the conversion sleeve; and the first threaded holes and the second threaded holes are tightened and fixed by bolts.

[0012] Furthermore, a center hole is formed at the front end of the conversion sleeve.

[0013] Furthermore, a protective cone is arranged at the front end of the center hole.

[0014] The beneficial effects of the utility model are:

[0015] By connecting the workpiece to the fixed rod and rotating the machine tool to achieve the processing of the outer arc of the rotary cutting head, the operation cost is reduced and the production efficiency is improved;

[0016] By setting the slot, the connection between the workpiece and the fixing rod is more stable, avoiding the problem that the workpiece cannot fit tightly with the bottom of the fixing slot due to the machining accuracy of the machine tool;

[0017] By setting the conversion sleeve, the device can be adapted to different processing machine tools, such as lathes, EDM machines or laser machines, which can facilitate the adaptive processing of different machine tools. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following describes the implementation of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0023] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed at will, and the component layout may also be more complicated. Example

[0024] like Figure 2~Figure 3 As shown:

[0025] A device for grinding PCD outer arc, comprising:

[0026] A fixing rod 1; both ends of the fixing rod 1 are provided with tops 11;

[0027] The fixing rod 1 is provided with a fixing groove 2; both ends of the fixing groove 2 are vertically arranged; and both ends of the fixing groove 2 are provided with anti-slip patterns. By providing the fixing groove 2, the workpiece 4 can be installed, and the square workpiece 4 is bonded in the fixing groove 2 to achieve a stable connection.

[0028] The bottom of the two end surfaces of the fixing groove 2 is provided with slots 22; the slots 22 are arranged in an arc shape; the bottom of the slots 22 is flush with the bottom surface of the fixing groove 2. By providing the slots 22, the workpiece 4 and the fixing groove 2 are better clamped and fixed. In the machining of mechanical equipment, due to the accuracy and angle problems of the tool head, it is impossible to achieve precise machining of the right angles on the workpiece. Therefore, if the slots 22 are not provided at the bottom of the fixing groove 2, and the workpiece 4 is directly installed at a right angle, the bottom of the workpiece 4 cannot fit tightly with the bottom surface. Therefore, the slots 22 are provided, and the problem of the right angle machining accuracy is directly avoided by the slots 22.

[0029] The bottom surface of the fixing groove 2 is provided with a base glue 21. By providing the base glue 21 and the anti-skid pattern on the end surface, the clamping strength is further improved.

[0030] Conversion sleeves 3 are provided at both ends of the fixing rod 1; the conversion sleeve 3 is buckled on the end of the fixing rod 1. First threaded holes 12 are provided at both ends of the fixing rod 1; a second threaded hole 32 corresponding to the first threaded hole 12 is provided on the conversion sleeve 3; the first threaded hole 12 and the second threaded hole 32 are tightened and fixed by bolts 33. A center hole 34 is provided at the front end of the conversion sleeve 3. A protective cone 341 is provided at the front end of the center hole 34. By setting up this scheme, replaceable center hole 34 and top 11 can be realized, which can be adapted to different machine tools; at the same time, since the equipment needs to be disassembled and used many times, a protective cone 341 is provided to protect the center hole 34.

[0031] How this device works

[0032] Place the workpiece 4 in the fixing groove 2. The bottom surface of the fixing groove 2 is provided with a base glue 21. The workpiece 4 is tightly fitted with the base glue 21. After clamping and fixing, choose whether to use the conversion sleeve 3 according to the machine tool model, then install the device on the machine tool, align the coaxiality, and then process the workpiece 4 through the cylindrical grinder.

[0033] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
