Description

Technical Field

[0001] The invention relates to the field of automobile maintenance machinery, in particular to a polishing and grinding machine. Background Art

[0002] The brake disc is a round plate. The brake caliper of the vehicle clamps the brake disc to generate braking force, which plays the role of slowing down or stopping the car. The brake disc has a good braking effect and is easier to maintain than drum brakes.

[0003] If the brake disc is slightly damaged, it can be repaired and used again. The damaged brake disc is repaired by the corresponding processing machine tools. Generally, the lathe uses a turning tool to cut the brake disc surface, and the grinder is required to grind the brake disc surface, also known as light grinding. In this way, two machine tools are required, which is costly and occupies space. In addition, the cutting and grinding processes require two clamping processes.

[0004] Currently, there are solutions that integrate cutting and grinding on one device, but they take up a lot of space. Summary of the invention

[0005] The present invention provides a polishing and grinding machine, the purpose of which is to solve the shortcomings of the prior art, to achieve turning and grinding of brake discs on one machine tool, to reduce costs, to improve production efficiency, and to reduce occupied space.

[0006] The technical solution adopted by the present invention to solve its technical problem is:

[0007] The polishing and grinding machine is characterized by:

[0008] A transverse feed system is installed on the machine platform, and a screw is provided in the inner pivot of the transverse feed system, and the screw is driven by a motor or a hand wheel; a longitudinal feed system is installed on the machine platform, and the longitudinal feed system is connected to and drives the transverse feed system, and the longitudinal feed system is driven by a motor or a hand wheel;

[0009] The slider is embedded in the slide rail, and the nut on the slider is screwed with the screw rod;

[0010] A grinding motor of the grinding system is installed on the slider, and an output shaft of the grinding motor is connected to and drives the grinding blade to rotate;

[0011] The top end of the tool holder of the turning system is equipped with a turning tool, and the bottom end of the tool holder is hinged to the slide block by a hinge shaft;

[0012] The motor shaft of the brake disc motor installed on the machine is connected to and drives the brake disc to rotate.

[0013] When the turning tool corresponds to the state of the brake disc, the turning tool holder is located above the output shaft of the grinding motor, and the turning tool extends out in front of the grinding blade.

[0014] The utility model has two nuts, the threads of the two nuts are opposite to each other, and the position of the brake disc corresponds to the middle position of the two turning tools and also corresponds to the middle position of the two grinding blades.

[0015] A front limit stopper is provided on the front side of the tool holder and a rear limit stopper is provided on the rear side. The front limit stopper and the rear limit stopper are installed on the slide block or on the housing of the grinding motor.

[0016] The hinge shaft is located behind the output shaft of the grinding motor or in front of the output shaft.

[0017] The present invention is beneficial in that:

[0018] The present invention can realize turning and grinding of brake discs on one machine tool, and the switching of processing states is convenient, and the installation of two tools and the feeding during processing are not affected, thereby reducing costs and improving production efficiency. In addition, the hinge shaft of the tool holder is behind the output shaft of the grinding motor, so when the tool holder is put down, the tool holder, the grinding motor and the grinding blade can overlap in the horizontal direction, thereby reducing the occupied space.

In addition, the terms "first", "second", "third", etc., etc. are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0024] like Figure 1 As shown:

[0025] A transverse feed system 3 is installed on the machine platform 1. The transverse feed system 3 includes a slide rail 32 and a screw rod 31 pivotally arranged in the slide rail 31. The screw rod 31 can be driven by a motor or a hand wheel.

[0026] A longitudinal feeding system 2 is installed on the machine platform 1. The longitudinal feeding system 2 is connected to and drives the transverse feeding system 3 to move longitudinally. The longitudinal feeding system 2 can be driven by a motor or a hand wheel.

[0027] The slide block 71 is embedded in the slide rail 31 , and the nut 72 on the slide block 71 is threadedly mounted on the screw rod 31 .

[0028] The grinding motor 52 of the grinding system 5 is mounted on the slider 71 , and the output shaft 51 of the grinding motor 52 is connected to and drives the grinding blade 50 to rotate.

[0029] The turning system 4 has a turning tool holder 42, a turning tool 40 is installed at the top of the turning tool holder 42, and the bottom of the turning tool holder 42 is hinged to the slider 71 by a hinge shaft 41, or can be hinged to the housing of the grinding motor 52, which is equivalent to being hinged to the slider 71. Preferably, the hinge shaft 41 is located behind the output shaft 51 of the grinding motor 52 (it can also be located in front of the output shaft 51 to achieve the same purpose).

[0030] The motor shaft 62 of the brake disc motor 61 installed on the machine platform 1 is connected to and drives the brake disc 6 to rotate.

[0031] There are two nuts 72, and the threads of the two nuts 72 are opposite to each other. In this way, when the screw rod 71 rotates, the two grinding systems 5 are relatively close to or far away from each other, and the two turning systems 4 are also relatively close to or far away from each other.

[0032] The position of the brake disc 6 corresponds to the middle position of the two turning tools 40 , and also corresponds to the middle position of the two grinding blades 50 .

[0033] The front side of the tool holder 42 has a front limit stopper, and the rear side has a rear limit stopper (not shown in the figure). The front limit stopper and the rear limit stopper can be installed on the slider 71 or on the housing of the grinding motor 52. Figure 1 As shown, the turning tool 40 is retracted, and the turning tool holder 42 rotates around the hinge shaft 41 and rests on the rear limit stopper.

[0034] like Figure 2 The turning tool 40 shown corresponds to the state of the brake disc 6 , at which time the turning tool holder 42 is horizontally placed on the limit block, and the turning tool holder 42 is located above the output shaft 51 of the grinding motor 52 , and the turning tool 40 extends in front of the grinding blade 50 .

[0035] When using:

[0036] When the brake disc 6 needs to be ground, Figure 1 As shown, the tool holder 42 is retracted so that it does not interfere with the grinding system 5 , the lateral feed system 3 and the longitudinal feed system 2 are adjusted so that the grinding blades 50 on both sides clamp the brake disc 6 , the grinding motor 52 is started, and the grinding blades 50 rotate to grind the brake disc 6 .

[0037] When the brake disc 6 needs to be turned, Figure 2 As shown, the tool holder 42 is lowered, and the tool 40 corresponds to the brake disc 6. The transverse feed system 3 is adjusted, the brake disc motor 61 is started to rotate the brake disc 6, and the longitudinal feed system 2 is started to make the tool 40 turn the brake disc 6.

[0038] In this specification, each embodiment is described in a progressive manner, and each embodiment focuses on the differences from other embodiments, and the same and similar parts between the embodiments can be referred to each other. The above description of the disclosed embodiments enables professionals and technicians in this field to implement or use the present invention. Various modifications to these embodiments will be obvious to professionals and technicians in this field, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to these embodiments shown in this article, but will comply with the widest range consistent with the principles and novel features disclosed herein.
