Description

Technical Field

[0001] The utility model relates to the field of automobile repair machinery, in particular to a combined lathe and grinder for repairing brake discs. Background Art

[0002] A brake disc is a circular plate. The vehicle's brake calipers clamp the brake disc to generate braking force, playing a role in decelerating or stopping the vehicle. The brake disc has good braking effect and is easier to maintain than drum brakes.

[0003] If the brake disc is slightly damaged, it can be reused after repair. The damaged brake disc is repaired by a corresponding processing machine tool. Generally, a lathe uses a turning tool to cut the brake disc surface, and in addition, a grinding machine is required to grind the brake disc surface. In this way, two machine tools are needed, resulting in high costs, large floor space, and two clamping processes for cutting and grinding. Summary of the Utility Model

[0004] The utility model provides a combined lathe and grinder for repairing brake discs, aiming to solve the shortcomings of the prior art and realizing turning and grinding of brake discs on one machine tool, reducing costs and improving production efficiency.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows:

[0006] The combined lathe and grinder for repairing brake discs is characterized in that:

[0007] A transverse feed system is installed on the machine table. A screw rod is pivotally arranged in the transverse feed system and is driven by a motor or a handwheel.

[0008] A longitudinal feed system is installed on the machine table. The longitudinal feed system is connected to and drives the transverse feed system and is driven by a motor or a handwheel.

[0009] The nut of the turning system is in threaded cooperation with the screw rod of the transverse feed system.

[0010] The turning system has a tool holder, and a turning tool is installed at the end of the tool holder.

[0011] A grinding system is hinged to the outside of the tool holder. The support rod of the grinding system is hinged to the outside of the tool holder by a hinge shaft, and a grinding motor is installed at the end of the support rod. The output shaft of the grinding motor is connected to and drives the grinding blade to rotate.

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

[0013] The transverse feed system includes a slide rail, and the slider of the turning system is fitted and embedded on the slide rail.

[0014] There are two turning systems. The threads of the nuts of the two turning systems are reversed. 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] There is a stop block on the outside of the tool rest. When the support rod of the grinding system is mounted on the card slot to support the support rod, the grinding blade corresponds to the brake disc.

It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be construed as a limitation on the present invention. In addition, the terms "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0024] As Figure 1 shown:

[0025] A transverse feed system 3 is installed on the machine table 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 handwheel.

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

[0027] The slider 41 of the turning system 4 is fitted and embedded on the slide rail 31, and the nut 44 on the slider 41 is in screw fit with the screw rod 31.

[0028] A tool holder 42 is installed on the slider 41, and a turning tool 40 is installed at the end of the tool holder 42.

[0029] A grinding system 5 is hinged to the outside of the tool holder 42. The support rod 53 of the grinding system 5 is hinged to the outside of the tool holder 42 by a hinge shaft 54. A grinding motor 52 is installed at the end of the support rod 53, and the output shaft 51 of the grinding motor 52 is connected to and drives the grinding blade 50 to rotate.

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

[0031] There are two turning systems 4, and the threads of the nuts 4 of the two turning systems 4 are reverse. In this way, when the screw rod 31 rotates, the two turning systems 4 approach or move away from each other relatively. At the same time, the two grinding systems 5 also approach or move away from each other relatively.

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

[0033] The outer side of the tool rest 42 has a clamping groove 43 as a stop block. As Figure 1 shown in the state where the grinding blade 50 corresponds to the brake disc 6, the support rod 53 of the grinding system 5 is erected on the clamping groove 43 to support the support rod 53. As Figure 2 shown, when the grinding blade 50 is retracted, the support rod 53 rotates around the hinge shaft 54 and rests on the slider 41, and the grinding blade 50 is located behind the tool rest 42.

[0034] The clamping groove can also be installed on the support rod 53 and open downward. In this way, Figure 1 in the state, the clamping groove is erected on the tool rest 42 to support the support rod 53.

[0035] During use:

[0036] When the brake disc 6 needs to be ground, as Figure 1 shown, the support rod 53 is erected on the clamping groove 43, the grinding blade 50 is located in the front, the transverse 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, and the grinding motor 52 is started, and the grinding blade 50 rotates to grind the brake disc 6.

[0037] When the brake disc 6 needs to be turned, as Figure 2 shown, the support rod 53 rotates around the hinge shaft 54 and rests on the slider 41, the grinding blade 50 is located behind the tool rest 42, and the working position of the turning tool 40 is vacated. 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 turn the brake disc 6 with the turning tool 40.

[0038] In this specification, each embodiment is described in a progressive manner. The key point of each embodiment is to illustrate the differences from other embodiments. The same or similar parts among the embodiments can be referred to each other. The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be obvious to those skilled in the art. 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 herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
