Description

Technical Field

[0001] This utility model relates to the field of automotive repair machinery, specifically a novel integrated machine for both polishing and grinding. Background Technology

[0002] A brake disc is a round plate. The vehicle's brake calipers clamp the brake disc to generate braking force, thus slowing down or stopping the vehicle. Brake discs offer better braking performance and are easier to maintain than drum brakes.

[0003] Minor damage to brake discs can be repaired and reused. Damaged brake discs are repaired using corresponding machine tools. Generally, a lathe is used to cut the brake disc surface with a cutting tool, and a grinding machine is needed to grind the brake disc surface, also known as surface grinding. This requires two machine tools, which is costly, takes up space, and requires two clamping operations for both cutting and grinding.

[0004] Currently, there are also integrated grinding and polishing machines that combine cutting and grinding on one machine, but they occupy a large space, are cumbersome to operate, and require loosening and tightening multiple fasteners. Utility Model Content

[0005] This utility model provides a novel integrated machine for both turning and grinding, which aims to overcome the shortcomings of existing technologies and enable the turning and grinding of brake discs on a single machine tool, thereby reducing costs, improving production efficiency, reducing space requirements, and simplifying operation.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] The new type of integrated polishing and grinding machine is characterized by:

[0008] A transverse feed system is installed on the machine base, and a screw is pivotally installed in the transverse feed system. The screw is driven by a motor or handwheel. A longitudinal feed system is installed on the machine base, which is connected to and drives the transverse feed system. The longitudinal feed system is driven by a motor or handwheel.

[0009] The slider is fitted onto the slide rail, and the nut on the slider is screwed onto the screw rod.

[0010] The cutting tool holder is mounted on the slider, and the grinding motor that drives the grinding tool is mounted on the cutting tool holder.

[0011] The lathe tool post is placed on the upper surface of the cutting tool post. The screw and nut assembly passes through the strip-shaped vertical through hole provided on the lathe tool post and the strip-shaped vertical through hole provided on the cutting tool post, so that the lathe tool post is installed on the cutting tool post. The lathe tool post can move back and forth and rotate.

[0012] A lathe tool is mounted on the front end of the tool holder;

[0013] The tool post has an inner cavity, which is connected to the bottom surface of the tool post by a vertical hole and to the top surface of the tool post by a top groove. The top groove extends from the front to the back from the inside to the outside. The inner and outer sides of the tool post have transverse through holes that communicate with the inner cavity.

[0014] The drive shaft has a semi-annular groove in the middle, and the bottom surface of the semi-annular groove has a crank handle through hole that communicates with the outer wall of the drive shaft. The two side walls of the semi-annular groove each have an eccentric through hole parallel to the axis.

[0015] The drive shaft is located inside the tool post, and its two ends pass through the transverse through holes of the tool post;

[0016] The support rod passes through the through hole of the cutting tool holder and the vertical hole of the lathe tool holder and extends into the semi-annular groove of the drive shaft. The protrusion at the bottom of the support rod abuts against the bottom surface of the lathe tool holder. The top of the support rod is fixed with the outer ring of a bearing. The horizontal shaft passes through the inner ring of the bearing. Both ends of the horizontal shaft pass through the eccentric through holes in the side wall of the semi-annular groove.

[0017] The crank handle passes through the crank handle through hole of the drive shaft, and the bottom end of the crank handle is fixedly connected to the horizontal shaft.

[0018] The grinding insert is mounted on the grinding insert shaft, which is inserted into a transverse hole on the grinding tool holder. A grinding motor is mounted on the cutting tool holder, and the output shaft of the grinding motor is connected to and drives the grinding insert shaft to rotate.

[0019] The cutting tool is installed in a groove at the front end of the cutting tool holder.

[0020] The nut is screwed onto the bottom thread of the support rod, and the nut acts as a protrusion that abuts against the bottom surface of the tool holder.

[0021] The advantages of this utility model are:

[0022] This invention enables the simultaneous turning (finishing) and grinding (grinding) of brake discs on a single machine tool, improving machining accuracy and speed. Turning allows for better and faster grinding, while grinding improves the precision and surface finish of the turn. Switching between machining modes is convenient and does not affect the installation of either tool or the feed rate during machining, thus reducing costs and increasing production efficiency. The tool holder can be driven to feed and retract using a handle, allowing the turning tool or grinding insert to be in the working position, simplifying operation and reducing space requirements.

[0023] The structure of this utility model ensures that turning and grinding processes, that is, both [light] and [grind] are carried out on the same track, thereby increasing the machining accuracy and parallelism. Attached Figure Description

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown:

[0032] Longitudinal: The direction toward brake disc 6 is forward, and the direction away from brake disc 6 is backward.

[0033] Lateral: The direction towards brake disc 6 is inward, and the direction away from brake disc 6 is outward.

[0034] A transverse feed system 3 is installed on the machine base 1. The transverse feed system 3 includes a slide rail 32 and a screw 31 pivotally mounted in the slide rail 31. The screw 31 can be driven by a motor or a handwheel.

[0035] The machine tool 1 is equipped with a longitudinal feed system 2, which 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.

[0036] The slider 41 is fitted onto the slide rail 32, and the nut 44 on the slider 41 is screwed onto the screw rod 31.

[0037] A cutting tool holder 42 is mounted on the slider 41, and a grinding blade 50 is mounted on a grinding blade shaft 51. The grinding blade shaft 51 is inserted into a transverse hole 421 on the grinding tool holder 42. A grinding motor is mounted on the cutting tool holder 42, and the output shaft of the grinding motor is connected to and drives the grinding blade shaft 51 to rotate, which also drives the grinding blade 50 to rotate.

[0038] The tool holder 9 is placed on the upper surface of the cutting tool holder 42. The screw and nut assembly 43 passes through the strip-shaped vertical through hole 95 provided on the tool holder 9 and the strip-shaped vertical through hole 423 provided on the cutting tool holder 42, thereby installing the tool holder 9 on the cutting tool holder 42. The tool holder 9 can move back and forth and rotate.

[0039] A cutting tool 40 is mounted on the groove 91 at the front end of the tool holder 9.

[0040] The tool post 9 has an inner cavity, which is connected to the bottom surface of the tool post 9 by a vertical hole 94. The inner cavity is connected to the top surface of the tool post 9 by a top groove 93. The top groove 93 gradually extends from the inside to the outside from front to back, that is, the top groove 93 is inclined, with the front end closer to the inside and the rear end closer to the outside, and gradually transitions. The inner and outer sides of the tool post 9 each have transverse through holes 92 that communicate with the inner cavity.

[0041] The drive shaft 96 has a semi-annular groove 98 in the middle. The bottom surface of the semi-annular groove 98 has a crank handle through hole 90 that communicates with the outer wall of the drive shaft 96. The two side walls of the semi-annular groove 98 each have an eccentric through hole 97 parallel to the axis.

[0042] The drive shaft 96 is placed inside the tool post 9, with both ends passing through the transverse through holes 92 of the tool post 9.

[0043] The support rod 8 passes through the through hole 422 of the cutting tool holder 42 and the vertical hole 94 of the turning tool holder 9 and extends into the semi-annular groove 98 of the drive shaft 96. The nut 81 is screwed onto the bottom thread of the support rod 8. The nut 81 acts as a protrusion and abuts against the bottom surface of the turning tool holder 42. The top of the support rod 8 is fixed with the outer ring of a bearing 82. The horizontal shaft 83 passes through the inner ring of the bearing 82. Both ends of the horizontal shaft 83 pass through the eccentric through holes 97 on the side wall of the semi-annular groove 98.

[0044] The crank handle 99 passes through the crank handle through hole 90 of the drive shaft 96, and the bottom end of the crank handle 99 is fixedly connected to the horizontal shaft 83.

[0045] When using:

[0046] When it is necessary to machine brake disc 6, such as Figure 1 As shown, adjust the transverse feed system 3 and the longitudinal feed system 2. At this time, the crank handle 99 is in the rearward position, and the tip of the cutting tool 40 is located in front of and inside the grinding insert 50.

[0047] In this way, when the cutting tool 40 cuts the brake disc 6, the grinding insert 50 is located behind and outside the tip of the cutting tool 40, and will not touch the brake disc 6.

[0048] When it is necessary to grind the brake disc 6, push the crank handle 99 forward. Since the horizontal shaft 83 is the eccentric shaft of the drive shaft 96 and the crank handle 99 moves in the inclined top groove 93, the tool holder 9 moves backward and rotates outward relative to the screw and nut assembly 43, and the tip of the cutting tool 40 is displaced to the rear and outside of the grinding insert 50.

[0049] In this way, when the grinding insert 50 grinds the brake disc 6, the grinding insert 50 is located in front of and inside the tip of the cutting tool 40, and the tip of the cutting tool 40 will not touch the brake disc 6.

[0050] The various embodiments described in this specification are presented in a progressive manner, with each embodiment focusing on its differences from other embodiments. Similar or identical parts between embodiments can be referred to interchangeably. The above description of the disclosed embodiments enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
