Description

Technical Field

[0001] The utility model relates to the field of processing machinery, in particular to the structural design of a feeding transmission mechanism of a precision grinding machine tool. Background Art

[0002] There are two types of feeding and transmission mechanisms for precision grinding machines in the prior art. The first type is belt transmission, which has a simple structure and low cost, but its disadvantages are also obvious, such as insufficient speed ratio and obstruction during transmission, which is unstable and affects the processing accuracy. The second type is a worm gear mechanism, which effectively solves the problems of belt transmission and has the characteristics of a larger speed ratio and relatively stable transmission. However, this type of transmission structure also inevitably has the defects of high cost and troublesome maintenance. Summary of the invention

[0003] The utility model adopts a gear transmission mode, which not only solves the shortcomings of relatively small speed change and unstable transmission caused by belt transmission in the prior art, but also solves the technical problems of high cost and troublesome maintenance caused by worm gear transmission system.

[0004] The utility model is designed to solve the above technical problems. The feeding mechanism of the precision grinding machine tool comprises a power device of the feeding mechanism, a material guide plate for conveying materials to the processing position, and a transmission mechanism connecting the power device and the material guide plate, wherein the transmission mechanism is a gear transmission mechanism.

[0005] The transmission mechanism comprises a driving gear mounted on the output shaft of the power device and a driven gear mounted on the rotating shaft of the material guide plate and meshing with the driving gear.

[0006] The transmission mechanism includes a driving gear mounted on the output shaft of the power device and a driven gear mounted on the rotating shaft of the guide plate, and also includes an intermediate gear disposed between the driving gear and the driven gear and meshing with the above two gears. The module of the driving gear, the driven gear and the intermediate gear is 2, the number of teeth of the driving gear is 20, the number of teeth of the intermediate gear is 70, and the number of teeth of the driven gear is 80. The transmission mechanism also includes an adjustment bracket, the adjustment bracket is provided with a strip-shaped adjustment groove, and the rotating shaft of the intermediate gear is placed in the adjustment groove.

[0007] The utility model adopts a gear transmission system, which not only realizes stable transmission, but also further reduces costs and facilitates maintenance under the premise of meeting the technical accuracy requirements of the precision grinding machine tool. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of a feeding system of a precision grinding machine tool of the utility model. DETAILED DESCRIPTION

[0009] The specific embodiments of the present utility model are described in conjunction with the accompanying drawings.

[0010] Depend on Figure 1 It can be seen that the feeding mechanism of the precision grinding machine tool of the utility model includes a power device 10 of the feeding mechanism, a guide plate 20 for conveying materials to the processing position, and a transmission mechanism 30 connecting the power device 10 and the guide plate 20, and the transmission mechanism 30 is a gear transmission mechanism. The utility model adopts a gear transmission system, which can not only achieve smooth transmission, but also reduce costs and improve maintenance convenience. Of course, when designing and selecting parameters such as the gear module and the number of teeth, it is necessary to specifically consider meeting the technical requirements of workpiece grinding.

[0011] If for a grinding machine with a low speed ratio, the transmission mechanism 30 of the utility model includes a driving gear 31 installed on the output shaft 11 of the power device 10 and a driven gear 32 installed on the rotating shaft 21 of the guide plate 20 and meshing with the above-mentioned driving gear 31. This direct meshing method can further simplify the structure and reduce costs.

[0012] However, for the grinding of high-precision parts, the transmission method with a low gear ratio obviously cannot meet the requirements, so the transmission mechanism 30 of the utility model includes a driving gear 31 installed on the output shaft 11 of the power device 10 and a driven gear 32 installed on the rotating shaft 21 of the guide plate 20, and also includes an intermediate gear 33 arranged between the driving gear 31 and the driven gear 32 and meshing with the above two gears. The specific design parameters are that the module of the driving gear 31, the driven gear 32 and the intermediate gear 33 is 2, the number of teeth of the driving gear 31 is 20, the number of teeth of the intermediate gear 33 is 70, and the number of teeth of the driven gear 32 is 80. The parameter selection in this scheme mainly depends on the grinding accuracy level of the grinder, so as to adjust the grinding wheel speed during grinding. In order to increase the adjustability of the transmission system, the transmission mechanism 30 of the utility model also includes an adjustment bracket 34, on which a strip-shaped adjustment groove 341 is provided, and the rotating shaft 331 of the intermediate gear 33 is placed in the adjustment groove 341, and a fixing or tensioning mechanism is required between the rotating shaft 331 of the intermediate gear 33 and the bracket to keep the intermediate gear in a tightly connected state with the above-mentioned two gears.

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.
