Description
Technical Field
[0001] The invention relates to the technical field of chip cutting, in particular to an automobile motor housing grinder which is convenient for collecting grinding chips. Background Art
[0002] Automobile motor housing grinding machine is a special equipment used for grinding and polishing the surface of automobile motor housing. Its purpose is to remove burrs, flaws, oxide layers, etc. on the surface of the housing, so that the surface of the housing reaches a certain roughness and flatness requirements to meet the assembly and performance requirements of the motor, and at the same time, it can also improve the appearance quality of the housing.
[0003] The automobile motor housing grinder mainly drives the grinding tools (such as grinding wheels, grinding belts, and grinding heads) to rotate or reciprocate at high speed through motors. When the automobile motor housing is placed on the workbench and fixed, the grinding tool contacts the housing surface and the housing is ground using the abrasive particles on the surface of the grinding tool. For example, the grinding wheel of the grinding machine rotates at high speed driven by the motor, and the abrasive particles on its surface are like countless tiny knives, constantly cutting the material on the housing surface, thereby achieving the purpose of grinding.
[0004] Motor housings are usually divided into various shapes such as cylindrical, square, polygonal, etc. When grinding and clamping cylindrical motor housings, because the outer wall of the housing is arc-shaped, when using conventional clamping methods and clamping parts, the housing and the clamping parts are in line contact or small-area surface contact. Compared with the clamping of flat objects, the friction and support force are limited; when grinding, the vibration and impact force generated by the interaction between the grinding tool and the housing are transmitted along the arc-shaped outer wall, which can easily destroy the balance between the housing and the clamping parts, making the housing very easy to fall off; this not only interrupts the grinding work and affects efficiency, but also may damage the housing, and in severe cases, it may be scrapped and increase costs; if the housing falls off during high-speed grinding, it may collide with tools or other equipment, generating fragments, endangering the safety of operators and damaging the surrounding environment.
[0005] In view of this, the present invention provides an automobile motor housing grinder which is convenient for collecting grinding chips. Summary of the invention
[0006] The object of the present invention is to provide an automobile motor housing grinder which is convenient for collecting grinding chips, so as to solve the problems raised in the above-mentioned background technology.

The clamping assembly moves upward to drive the casing body upward, so that the grinding piece grinds the inner and outer walls of the casing body. When the grinding piece passes through the clamping assembly, it drives the clamping assembly to expand, and the casing body is separated from the clamping assembly.
[0008] As a further improvement of the present technical solution, the grinding assembly also includes a rotating plate, a slide rail is fixedly connected to the inside of the rotating plate near the bottom, a double-headed cylinder is fixedly connected to the top of the slide rail located inside the rotating plate, and grinding parts are provided inside the slide rail near both ends.

[0011] As a further improvement of the technical solution, the sliding member includes two long plates, one of which is fixedly connected to the convex plate, and vertical rods are movably connected inside the long plate near both ends, and the vertical rods are fixedly connected to the top of the collection box.
[0012] As a further improvement of the technical solution, two sliders are movably connected inside the long board, the two sliders are fixedly connected to the two clamping plates respectively, and an elastic member is fixedly connected between the two sliders.
[0013] As a further improvement of the technical solution, the clamping plates are inclined plates, and grooves are provided on the outer walls of the opposite sides of the two clamping plates near the bottom.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. In the automobile motor case grinder that is convenient for collecting grinding chips, the case body is clamped and fixed by a clamping assembly to ensure that the case body does not shake during the complex grinding process; the grinding parts are cleverly placed between the inner and outer walls of the case body through the grinding assembly, forming a secondary clamping mode, which enhances the stability of the case during the grinding process.
[0016] 2. In the automobile motor case grinder that is convenient for collecting grinding chips, the clamping assembly moves upward, thereby driving the case body to move upward.

[0019] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For examples, see Figure 1-Figure 4 As shown, the purpose of this embodiment is to provide an automobile motor housing grinder that is convenient for collecting grinding chips, including a vertical plate 1, a top plate 11 is fixedly connected to the outer wall of the vertical plate 1 near the top, a grinding assembly 13 is provided at the bottom of the top plate 11, and the grinding assembly 13 includes a grinding piece 133; A collection box 12 is fixedly connected to the outer wall of the vertical plate 1 near the bottom, a clamping assembly 14 is provided between the top of the collection box 12 and the outer wall of the vertical plate 1, and a housing body 2 is provided between the clamping assembly 14 and the grinding member 133; The grinding piece 133 and the clamping assembly 14 both clamp and fix the housing body 2. The clamping assembly 14 moves upward to drive the housing body 2 upward, so that the grinding piece 133 grinds the inner and outer walls of the housing body 2. When the grinding piece 133 passes through the clamping assembly 14, it drives the clamping assembly 14 to expand, and the housing body 2 is separated from the clamping assembly 14. The improvement of this embodiment is that: during the working process of the automobile motor housing grinder, firstly, the housing body 2 is initially clamped and fixed by the clamping assembly 14 to ensure that the housing body 2 is firmly fixed; on this basis, the grinding piece 133 is cleverly placed between the inner and outer walls of the housing body 2, thereby constructing a secondary clamping system, adding a solid defense line for the stability of the housing; during grinding, no matter how external factors interfere, such as the high-frequency vibration generated by the grinding tool, the uneven force in the grinding direction, etc., the housing body 2 can maintain extremely high stability by virtue of the double clamping, effectively avoiding the problem of reduced grinding accuracy due to shaking, and laying a solid foundation for high-quality grinding; Secondly, by the upward movement of the clamping assembly 14, the casing body 2 is driven to move upward synchronously. At this time, the grinding piece 133 located between the inner and outer walls of the casing rotates and grinds, so that the inner and outer walls of the casing body 2 are simultaneously grinded from top to bottom; this synchronous grinding method greatly improves the grinding efficiency while ensuring the consistency of the grinding quality of the inner and outer walls; and, when the clamping assembly 14 gradually moves to the critical node of the end of the grinding piece 133 near the bottom, the grinding piece 133 will apply an expansion force in a specific direction to the clamping assembly 14. This expansion force causes the casing body 2 to automatically and smoothly detach from the clamping assembly 14 at the moment of grinding. The entire process does not require manual intervention, and all operations from grinding to releasing the casing body 2 are completed smoothly and efficiently.
[0022] First, the specific structure of the grinding assembly 13 is disclosed. The grinding assembly 13 also includes a rotating plate 130. A slide rail 131 is fixedly connected to the bottom of the rotating plate 130. A double-headed cylinder 132 is fixedly connected to the top of the slide rail 131 located inside the rotating plate 130. Grinding parts 133 are provided near both ends of the slide rail 131. See also Figure 4 and Figure 5 As shown, the grinding piece 133 is moved between the inner and outer walls of the casing body 2 by the double-headed cylinder 132, so that the casing body 2 is clamped and the inner and outer walls of the casing body 2 are grinded later; the rotating plate 130 is driven to rotate by the output shaft of the motor, so that the rotating plate 130 drives the slide rail 131 and the double-headed cylinder 132 to rotate simultaneously, so that the grinding piece 133 rotates between the inner and outer walls of the casing body 2, and the inner and outer walls of the casing body 2 are grinded simultaneously; The grinding member 133 includes four supporting rods 1330, two supporting rods 1330 are movably connected near the two ends of the slide rail 131, a grinding wheel 1331 is coaxially connected near the bottom of the supporting rod 1330, and a supporting plate 1332 is fixedly connected to the top of the outermost supporting rods 1330 at both ends of the slide rail 131, and the two supporting plates 1332 are fixedly connected to the two ends of the double-head cylinder 132 respectively; See also Figure 2 and Figure 6 As shown, the double-headed cylinder 132 drives the support plate 1332 to move toward the center of the slide rail 131, so that the support rods 1330 near the two ends of the slide rail 131 push the two support rods 1330 near the center of the slide rail 131 toward the center of the slide rail 131, and then the double-headed cylinder 132 drives the support plate 1332 to move toward the two ends of the slide rail 131, and moves the support rods 1330 near the two ends of the slide rail 131 outward, so as to facilitate the placement of the housing body 2 between the support rod 1330 near the center of the slide rail 131 and the support rod 1330 near the end of the slide rail 131; The double-headed cylinder 132 drives the support plate 1332 to move toward the center of the slide rail 131 again, so that the grinding wheels 1331 at the ends of the support rods 1330 located at both ends of the slide rail 131 clamp the outer wall of the casing body 2; a micro motor (not shown in the figure) is coaxially connected between the grinding wheel 1331 and the support rod 1330, which is used to drive the grinding wheel 1331 to rotate at high speed; the rotating plate 130 rotates to drive multiple support rods 1330 to rotate with the rotating plate 130 as the center, so that the two support rods 1330 near the center of the slide rail 131 are squeezed close to the inner wall of the casing body 2 under the centrifugal effect of rotation, so that the two support rods 1330 located at both ends of the slide rail 131 are clamped on the inner wall of the casing body 2; at the same time, the multiple grinding wheels 1331 rotate, so that while clamping the inner and outer walls of the casing body 2, the inner and outer walls can be polished simultaneously.
[0023] Secondly, the specific structure of the clamping assembly 14 is disclosed. The clamping assembly 14 includes two sliding members 141, two clamping plates 140 are arranged between the two sliding members 141, and the housing body 2 is arranged between the two clamping plates 140. A convex plate 142 is fixedly connected to the outer wall of one of the sliding members 141, and a single-head cylinder 143 is fixedly connected to the top of the convex plate 142; the clamping plate 140 is an inclined plate, and a groove is arranged near the bottom of the outer wall of the opposite side of the two clamping plates 140; See also Figure 7 As shown, by pulling the two clamping plates 140 to stretch them inside the sliding member 141, the casing body 2 is placed between the two clamping plates 140. When the sliding member 141 drives the two clamping plates 140 to rebound, the casing body 2 is clamped and connected between the two clamping plates 140 through the grooves near the bottom of the clamping plates 140. The convex plate 142 is driven to move up and down by the single-head cylinder 143, so that the convex plate 142 drives the sliding member 141 to move up and down on the top of the collection box 12. The sliding member 141 moves, thereby driving the two clamping plates 140 and the casing body 2 to move up and down synchronously. See also Figure 3 As shown, when the casing body 2 moves upward, the inner and outer walls of the casing body 2 will rub between the outer walls of the multiple grinding wheels 1331, so that in the process of the casing body 2 moving upward, the multiple grinding wheels 1331 rotate to grind its inner and outer walls; when the clamping plate 140 moves near the bottom to the end of the grinding wheel 1331, the grinding wheel 1331 also grinds to the bottom of the casing body 2, and the grinding wheels 1331 located near the two ends of the slide rail 131 will push the clamping plate 140 to expand to the two ends, so that when the casing body 2 is polished, it loses the supporting force of the two clamping plates 140 to clamp and fix it, and falls off from between the two clamping plates 140 and moves downward; at the same time, the relative inclined surfaces of the two clamping plates 140 guide the debris generated during the grinding process, and block the debris and guide it into the collection box 12; The splint 140 is made of high manganese steel, which is a very hard alloy steel containing a high proportion of manganese and has excellent wear resistance and impact resistance. Due to its extremely high hardness, when the grinding wheel 1331 touches the splint 140, the hardness of the material exceeds the abrasive hardness of the grinding wheel 1331, so the grinding wheel 1331 has difficulty in grinding the surface of the splint 140. The sliding member 141 includes two long plates 1410, one of which is fixedly connected to the convex plate 142, and a vertical rod 1413 is movably connected near both ends of the long plate 1410, and the vertical rod 1413 is fixedly connected to the top of the collection box 12; two sliders 1411 are movably connected inside the long plate 1410, and the two sliders 1411 are respectively fixedly connected to the two clamping plates 140, and an elastic member 1412 is fixedly connected between the two sliders 1411; See also Figure 8 and Fig. 9 As shown, by pulling the two clamping plates 140, the sliders 1411 at both ends thereof are driven to move inside the long plate 1410. During the movement, the two sliders 1411 inside the same long plate 1410 will pull the elastic member 1412 between the two sliders 1411 to stretch. When the clamping plate 140 loses the pulling force, the elastic member 1412 will shrink and rebound to drive the two sliders 1411 to move quickly closer inside the long plate 1410, and drive the two clamping plates 140 to move closer to each other to clamp and fix the housing body 2. When the convex plate 142 moves up and down, one of the long plates 1410 is driven to move up and down. The long plate 1410 moves up and down on the outer wall of the vertical rod 1413. The plurality of vertical rods 1413 provide stability for the movement of the long plate 1410.
[0024] In order to collect the debris conveniently and receive the housing body 2 that falls off between the two clamping plates 140, a filter screen 120 is fixedly connected to the inside of the collection box 12 near the top, and the filter screen 120 is located directly below the housing body 2; Figure 3 and Figure 4 As shown, the casing body 2 falling downward is received and intercepted by the filter 120, and at the same time, the debris passes through the mesh of the filter 120 and is filtered inside the collection box 12, so as to facilitate the separation of the casing body 2 and the debris.
[0025] In summary, the working principle of this solution is as follows: First, by pulling the two clamping plates 140, the pulling force will be transmitted to the sliders 1411 at both ends of the clamping plates 140, so that the sliders 1411 move inside the long plate 1410; since there are two sliders 1411 inside each long plate 1410, the elastic member 1412 located between the two will be stretched during their movement; when the pulling force on the clamping plates 140 disappears, the elastic member 1412 begins to shrink and rebound by virtue of its elastic force, and this rebound action will drive the two sliders 1411 to quickly approach each other inside the long plate 1410; at the same time, the groove near the bottom of the clamping plate 140 comes into play, which can firmly clamp the housing body 2 between the two clamping plates 140, thereby effectively clamping and fixing the housing body 2; this method of driving the clamping plate 140 by the elastic member 1412 not only ensures the stability of the clamping, but also provides convenience for subsequent operations; The reciprocating motion of the double-headed cylinder 132 is used to prepare for the placement of the casing; the double-headed cylinder 132 first drives the support plate 1332 to move toward the center of the slide rail 131, and in this process, the support rods 1330 near the two ends of the slide rail 131 are pushed toward the center of the slide rail 131; then, the double-headed cylinder 132 drives the support plate 1332 to move toward the two ends of the slide rail 131, which in turn moves the support rods 1330 near the two ends of the slide rail 131 outward; through such a reciprocating operation, it is convenient to place the casing body 2 between the support rod 1330 near the center of the slide rail 131 and the support rod 1330 near the end of the slide rail 131, so as to prepare for the subsequent clamping and grinding operations. The position of the support rod 1330 is accurately controlled by the double-headed cylinder 132 during the whole process to ensure the accuracy and convenience of casing placement; By starting the double-headed cylinder 132 again, it drives the support plate 1332 to move toward the center of the slide rail 131; this action causes the grinding wheels 1331 at the ends of the support rods 1330 at both ends of the slide rail 131 to clamp the outer wall of the housing body 2; it should be noted here that the grinding wheel 1331 is coaxially connected to the support rod 1330 and is also connected to a micro motor (not shown in the figure). The function of this micro motor is to drive the grinding wheel 1331 to rotate at a high speed to reserve energy for subsequent grinding work. Through this design, the outer wall of the housing is stably clamped and prepared for grinding. The rotating plate 130 is driven to rotate by the motor output shaft, and the rotation of the rotating plate 130 will drive the slide rail 131 and the double-headed cylinder 132 to rotate simultaneously; during this rotation process, multiple support rods 1330 will perform circular motion with the rotating plate 130 as the center; as the rotation, the two support rods 1330 near the center of the slide rail 131 will squeeze close to the inner wall of the casing body 2 under the action of centrifugation, thereby completing the clamping of the inner wall of the casing body 2 together with the two support rods 1330 located at both ends of the slide rail 131; at the same time, multiple grinding wheels 1331 rotate at high speed driven by the micro motor, so that the inner and outer walls of the casing body 2 can be clamped while being polished synchronously, which greatly improves the polishing efficiency and polishing quality and ensures the uniformity of the inner and outer wall polishing; When the single-head cylinder 143 starts working, it drives the convex plate 142 to move up and down, and the movement of the convex plate 142 will drive one of the long plates 1410 to move up and down; the long plate 1410 moves up and down on the outer wall of the vertical rod 1413, and the multiple vertical rods 1413 provide stable support for the movement of the long plate 1410 to ensure the stability of its movement process; when the casing body 2 moves upward driven by the long plate 1410, the inner and outer walls of the casing body 2 will generate friction with the outer walls of the multiple grinding wheels 1331; in this upward movement process, since the grinding wheel 1331 rotates at a high speed, it can The inner and outer walls of the housing body 2 can be continuously polished; when the clamping plate 140 moves to the end of the grinding wheel 1331 near the bottom, it means that the housing body 2 has also moved to the bottom position for polishing. At this time, the grinding wheels 1331 located near the two ends of the slide rail 131 will exert an expansion force on the clamping plate 140 toward both ends; this expansion force causes the housing body 2 to lose the support force provided by the clamping and fixing of the two clamping plates 140 at the moment when the polishing is completed, so that the housing body 2 falls off from between the two clamping plates 140 and moves downward, realizing the function of automatic disengagement, and improving the automation degree of the entire polishing process; During the grinding process, the relative inclined surfaces of the two clamps 140 play an important role in guiding the debris; the debris generated during the grinding process will be blocked by the inclined surfaces of the clamps 140 and guided to the inside of the collection box 12; at the same time, a filter screen 120 is provided inside the collection box 12. When the casing body 2 falls off from between the clamps 140 and moves downward, the filter screen 120 will receive and intercept the casing body 2 to prevent the casing body 2 from falling into the debris, while the debris can pass through the mesh of the filter screen 120, be filtered and remain in the collection box 12, thereby conveniently separating the casing body 2 from the debris, keeping the working environment clean, and facilitating the subsequent processing of the debris.
