Description

Technical Field

[0001] This utility model relates to the field of surface grinding technology, specifically a surface grinding fixture that can automatically flip over. Background Technology

[0002] A surface grinder, also known as a surface lapping machine, is a commonly used grinding tool for metal products. It uses abrasive grains to cut the surface of the material. Through relative motion, the workpiece and the grinding wheel generate relative friction, thereby removing irregular and rough parts from the workpiece surface to achieve the required dimensions and surface quality. It is widely used in industries such as machinery, molds, instruments, electronics, automobiles, and aerospace. During the use of a surface grinder, it is necessary to use a fixture to hold and fix the workpiece.

[0003] Existing surface grinder fixtures typically require manual operation to clamp the workpiece, which not only increases the workload of workers but is also complex and inefficient. Furthermore, when the workpiece needs to be flipped, traditional fixtures often require the workpiece to be released from the clamp before it can be flipped manually. This process is time-consuming and labor-intensive, and it is not easy to achieve accurate workpiece flipping, which greatly limits the processing efficiency and applicability of surface grinder fixtures.

[0004] Therefore, there is a need for a surface grinder fixture that can automatically flip the workpiece, in order to solve the problems that existing surface grinder fixtures require manual operation and are not easy to flip the workpiece. Utility Model Content

[0005] The purpose of this utility model is to provide a surface grinder fixture that can automatically flip over, so as to solve the problem that the surface grinder fixtures in the prior art require manual operation and that the surface grinder fixtures are not easy to flip over.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a surface grinder fixture that can automatically flip over, comprising a grinder body, a worktable provided on the outer wall of the front end of the grinder body, a base plate installed on the top surface of the worktable, two sets of symmetrically distributed clamping mechanisms provided on the top surface of the base plate, and two sets of rotating components corresponding one-to-one with the two sets of clamping mechanisms provided on the top surface of the base plate.

[0007] Each clamping mechanism includes a T-shaped rod. A movable groove is formed through the outer wall of the front end of the transverse section of the T-shaped rod. A movable block is slidably connected inside the movable groove. An electric actuator is installed on one outer wall of the transverse section of the T-shaped rod. Two symmetrically distributed sliding grooves are formed on one outer wall of the longitudinal section of the T-shaped rod. A slider is slidably connected inside the sliding groove. A clamping plate is fixedly connected to one outer wall of the slider. Two guide grooves, corresponding one-to-one with and communicating with the two sliding grooves, are formed on the other outer wall of each slider. Guide rods are fixedly connected to the other outer walls of both sliders. A fixing plate is fixedly connected to one outer wall of each guide rod, passing through the guide groove. Connecting rods are rotatably connected to the outer walls of both ends of the movable block on one outer wall of each fixing plate.

[0008] It should be noted in the scheme that each set of rotating components includes a housing, a rotating shaft is rotatably connected between the inner walls of the two sides of the housing, a worm gear is fastened to the outer surface of the rotating shaft, a mounting plate is rotatably connected to one side of the outer wall of the rotating shaft through the outer wall of the housing and is coaxially fixedly connected to the rotating shaft, a worm gear is rotatably connected between the inner wall of the top surface and the inner wall of the bottom surface of the housing and meshes with the worm gear, and a motor is installed on the top surface of the housing.

[0009] It is worth noting that two parallel mounting plates are fixedly connected to the outer walls of both ends of the base plate, and a support base is fixedly connected to the center of the top surface of the base plate.

[0010] Furthermore, it should be noted that two parallel electric actuators are installed on both sides of the top surface of the base plate, and two symmetrically distributed fixing rods are fixedly connected to the outer wall of each mounting plate on the side away from the corresponding housing.

[0011] In a preferred embodiment, the output end of each of the electric actuators slides through one side wall of the corresponding movable slot and is fixedly connected to one side outer wall of the corresponding moving block. The two fixed rods on the same mounting plate are fixedly connected to the top and bottom surfaces of the corresponding T-shaped rod transverse section. The output end of the motor rotates through the inner wall of the top surface of the housing and is coaxially fixedly connected to the top end of the worm gear.

[0012] In a preferred embodiment, each of the mounting plates is fixedly connected to the workbench by bolts, and the output ends of the two electric actuators located on the same side are fixedly connected to the bottom surface of the corresponding housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By pulling the moving block with the electric actuator, the moving block drives the two corresponding connecting rods to rotate, which in turn causes the two corresponding clamping plates to move closer to each other. All four clamping plates work simultaneously to clamp the workpiece, eliminating the need for complex manual operations, reducing the workload of the workers, and effectively avoiding the problem of manual operation required for surface grinder fixtures.

[0015] 2. The housing is moved upward by the electric push rod two, and then the motor drives the worm gear to rotate, which in turn drives the worm wheel to rotate. The worm wheel drives the mounting plate to rotate through the rotating shaft, thereby realizing the workpiece flipping operation. There is no need to release the workpiece clamp and then manually flip the workpiece, which saves time and effort and effectively avoids the problem that the fixture of the surface grinder is not easy to flip the workpiece.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example: Figures 1-4As shown, this utility model provides a technical solution, including a grinding machine body 1, a worktable 2 is provided on the outer wall of the front end of the grinding machine body 1, a base plate 3 is installed on the top surface of the worktable 2, two sets of symmetrically distributed clamping mechanisms 4 are provided on the top surface of the base plate 3, and two sets of rotating components 5 corresponding to the two sets of clamping mechanisms 4 are provided on the top surface of the base plate 3.

[0023] Each clamping mechanism 4 includes a T-shaped rod 41. A movable groove 42 is provided through the outer wall of the front end of the transverse section of the T-shaped rod 41. A moving block 43 is slidably connected inside the movable groove 42. An electric push rod 411 is installed on one side of the outer wall of the transverse section of the T-shaped rod 41. Two symmetrically distributed sliding grooves 44 are provided on one side of the outer wall of the longitudinal section of the T-shaped rod 41. A slider 45 is slidably connected inside the sliding groove 44. A clamping plate 46 is fixedly connected to one side of the outer wall of the slider 45. Two guide grooves 47 are provided on the other side of the outer wall of the longitudinal section of the T-shaped rod 41, which correspond one-to-one with and communicate with the two sliding grooves 44. A guide rod 48 is fixedly connected to the other side of the outer wall of each slider 45. A fixing plate 49 is fixedly connected to one side of the outer wall of each guide rod 48 through the guide groove 47. A connecting rod 410 is rotatably connected to one side of the outer wall of each of the two fixing plates 49 and the outer walls of the two ends of the moving block 43.

[0024] Further as Figure 1 and Figure 4 As shown, it is worth noting that each set of rotating components 5 includes a housing 51, a rotating shaft 52 is rotatably connected between the inner walls of the two sides of the housing 51, a worm gear 53 is fastened to the outer surface of the rotating shaft 52, a mounting plate 54 is rotatably connected to one side of the outer wall of the housing 51 and is coaxially fixedly connected to one side of the outer wall of the rotating shaft 52, a worm 55 is rotatably connected between the inner wall of the top surface and the inner wall of the bottom surface of the housing 51 and meshes with the worm gear 53, and a motor 56 is installed on the top surface of the housing 51.

[0025] Further as Figure 1 As shown, it is worth noting that two parallel mounting plates 6 are fixedly connected to the outer walls of both ends of the base plate 3, and a support base 7 is fixedly connected to the center of the top surface of the base plate 3.

[0026] Further as Figure 1 and Figure 4 As shown, it is worth noting that two parallel electric actuators 8 are installed on both sides of the top surface of the base plate 3, and two symmetrically distributed fixing rods 9 are fixedly connected to the outer wall of each mounting plate 54 on the side away from the corresponding housing 51.

[0027] Further as Figure 2 and Figure 4As shown, it is worth noting that the output end of each electric actuator 411 slides through one side wall of the corresponding movable slot 42 and is fixedly connected to one side outer wall of the corresponding moving block 43. The electric actuator 411 drives the moving block 43 to move, thereby causing the clamping plate 46 to clamp the workpiece through the connecting rod 410. The two fixed rods 9 on the same mounting plate 54 are fixedly connected to the top and bottom surfaces of the transverse section of the corresponding T-shaped rod 41. The rotation of the mounting plate 54 drives the T-shaped rod 41 to rotate, thereby turning the workpiece over. The output end of the motor 56 rotates through the inner wall of the top surface of the housing 51 and is coaxially fixedly connected to the top of the worm gear 55. The motor 56 drives the worm gear 55 to rotate, so that the worm wheel 53 can drive the mounting plate 54 to rotate through the rotating shaft 52.

[0028] Further as Figure 1 and Figure 4 As shown, it is worth noting that each mounting plate 6 is fixedly connected to the worktable 2 by bolts, which facilitates the installation and disassembly of the base plate 3 and the worktable 2. The output ends of the two electric actuators 8 located on the same side are fixedly connected to the bottom surface of the corresponding housing 51 to prevent the base plate 3 from interfering with the rotation of the workpiece due to insufficient height.

[0029] In summary, when using this fixture, the base plate 3, clamping mechanism 4, and rotating assembly 5 are first installed onto the top surface of the worktable 2 using the mounting plate 6 and bolts. Then, the workpiece is placed on the top surface of the support base 7 and positioned between the four clamping plates 46. Simultaneously, the two electric actuators 411 are activated, which pull the moving block 43 to slide. Through the connecting rod 410, the corresponding two fixed plates 49 are brought closer together, thereby bringing the corresponding two clamping plates 46 closer together to clamp both ends of the workpiece. The two sets of clamping plates 46 work simultaneously to achieve the clamping operation of the workpiece. This eliminates the need for complex manual operations, reduces the workload of the operator, and effectively avoids the problem of manual operation required for surface grinder fixtures.

[0030] When it is necessary to flip the workpiece, multiple electric actuators 8 are activated simultaneously to push the two housings 51 and move the workpiece upward. When it reaches the appropriate height, two motors 56 are activated simultaneously to drive the two worm gears 55 to rotate. Under meshing action, the two worm gears 55 drive the two worm wheels 53 to rotate, which in turn drive the two clamping mechanisms 4 to rotate in the same direction through the two rotating shafts 52. This causes the clamped and fixed workpiece to rotate, realizing the workpiece flipping operation. It is not necessary to release the workpiece clamp and then manually flip it, which saves time and effort and effectively avoids the problem that it is not easy to flip the workpiece with the fixture of the surface grinder.

[0031] The electric actuator 411, motor 56, and electric actuator 8 can be purchased from the market and are mature technologies in this field, which have been fully disclosed. Therefore, they will not be described again in the specification.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
