Description

Technical Field

[0001] The invention relates to the field of mechanical processing, in particular to the structural design of a material guide plate of a precision grinding machine tool. Background Art

[0002] For the grinding of precision parts, the positioning and clamping of the workpiece must be accurate and firm. Ordinary clamping mechanisms are difficult to ensure accurate positioning. Therefore, a disc-type feeding mechanism is generally used in precision grinding machines. The workpiece is placed in the clamping position of the guide disc, which is both simple and accurate. In addition, since the gap between the clamping position and the workpiece is very small, it also prevents the workpiece from moving during the processing, which affects the processing accuracy. Based on the above requirements, the current precision grinding machine uses a steel guide disc for grinding small and fine workpieces. This steel guide disc not only meets the requirements for hardness and wear resistance, but also improves durability. However, although this steel guide disc meets the requirements for hardness and wear resistance, it lacks consideration and necessary protection measures for the protection of the workpiece. For example, for parts with relatively high surface requirements for the workpiece, after being processed with the above-mentioned steel guide disc, it is difficult to avoid scratches on the surface of the workpiece, thereby affecting the product qualification rate and increasing production costs. Summary of the invention

[0003] The present invention adopts a material guide disc made of non-metallic material or sets a non-metallic clamping position on the material guide disc to solve the technical problem of easily scratching the surface of the workpiece in the prior art.

[0004] The material guide plate of the precision grinding machine designed by the present invention to solve the above-mentioned technical problems includes a material guide plate body installed on the output shaft of the precision grinder feeding mechanism, and a plurality of material placement parts for placing the workpieces are arranged along the periphery of the material guide plate body, and the material bin arranged in the material placement part is made of non-metallic material.

[0005] The improvement of the present invention lies in that the material guide plate body, the material placement portion and the material bin are integrally made of non-metallic materials.

[0006] A further improvement of the present invention is that the material placing part and the material bin are assembled separately. A more specific solution is that the material placing part includes a movable mounting seat, a fixed seat is provided at the rear end of the material bin, and the material bin is fixed to the material placing part by the cooperation between the fixed seat and the movable mounting seat; or the material placing part is a concave part, and the material bin is a support embedded in the concave part.

[0007] A further improvement of the present invention is that the non-metallic material used to make the silo is glass fiber synthetic material, bakelite or nylon material.

[0008] The present invention adopts a material guide plate made of non-metallic material or sets a non-metallic clamp on the material guide plate. On the basis of meeting the hardness and wear resistance requirements of the material guide plate, it more effectively protects the surface of the workpiece from being scratched, effectively improves the qualified rate, improves production efficiency and reduces production costs.

[0010] Figure 2 It is a schematic diagram of the dovetail groove assembly method of the material guide plate of the present invention.

[0011] Figure 3 It is a schematic diagram of the supporting assembly method of the material guide tray of the present invention. DETAILED DESCRIPTION

[0012] The specific embodiments of the present invention are described in conjunction with the above drawings.

[0013] Depend on Figures 1 to 3 It can be seen that the guide plate of the precision grinding machine designed by the present invention includes a guide plate body 10 installed on the output shaft of the feed mechanism of the precision grinder, and a plurality of material placement parts 20 for placing the workpieces to be processed are arranged along the periphery of the guide plate body 10, and the material bin 21 arranged in the material placement part 20 is made of non-metallic material. The non-metallic material used to make the material bin 21 is a glass fiber synthetic material, and the non-metallic material used to make the material bin 21 can also be selected as bakelite or nylon material according to the material of the workpiece to be processed. The present invention adopts a material bin made of non-metallic material, so that the material bin and the workpiece will not scratch the surface of the workpiece during processing. Of course, for the selection of non-metallic materials, it is necessary to consider that the material must have sufficient hardness and must meet the requirements of sufficient support for the stress that may be generated during the processing of the workpiece. At the same time, in order to improve the economy and resist factors such as friction that may be generated during the processing, the material must also have certain wear resistance and high temperature resistance.

[0014] Depend on Figure 1 It can be seen that the material guide plate body 10, the material placement portion 20 and the material bin 21 are made of non-metallic materials in one piece.

[0015] Depend on Figure 2 and Figure 3It can be seen that the material placement part 20 and the material bin 21 of the present invention are assembled separately; more specific designs include: the material placement part 20 includes a movable mounting seat 22, and the tail end of the material bin 21 is provided with a fixed seat 23, and the material bin 21 is fixed to the material placement part 20 through the matching installation between the fixed seat 23 and the movable mounting seat 22. This structure fully limits the radial movement of the material bin and ensures the processing accuracy. In the assembly process, cold installation or appropriate transition fit can also limit the axial movement to a certain extent. For double-sided grinding machine processing, the axial thrust generated during the processing is negligible, which can fully meet the requirements of processing accuracy. The second solution can be that the material placement part 20 is a concave part, and the material bin 21 is a liner embedded in the concave part. This structure is relatively simple to assemble, and the liner processing is also relatively simple, with lower cost. Selecting an appropriate assembly method can fully meet the processing requirements.

[0016] The above contents are further detailed descriptions of the present invention in combination with specific preferred embodiments, and it cannot be determined that the specific implementation of the present invention is limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
