They are the basic units of machinery and include bolts, nuts, washers, pins, straight shafts, crankshafts, camshafts, eccentric shafts, stepped shafts, gears, worm gears, worms, etc. During the manufacturing process of mechanical parts, steps such as drilling, bending, and cutting are required. Burrs may appear on the surface of the mechanical parts, necessitating surface grinding. For straight shafts, a clamp is used to hold them in place during grinding to facilitate the process.
[0003] Patent CN222078862U discloses a tooling fixture for grinding mechanical parts. It is designed with a first telescopic cylinder that extends to raise the placement platform and lift the part, thus limiting the placement height of the part and improving the processing accuracy. It is designed with two second motors that rotate to drive the transmission shaft, thereby rotating the connecting plate and realizing the rotation of the clamping assembly, which in turn drives the rotation of the part. This allows for greater adjustment of the part's position and enables the part to rotate and flip, facilitating the grinding of the other end of the part.
[0004] The above-mentioned device is a single-piece clamping design, which can only clamp one mechanical part at a time. This means that the grinding device can only grind a single mechanical part at a time, and cannot adapt to clamping multiple mechanical parts, resulting in low work efficiency. Summary of the Invention
[0005] To solve the above-mentioned technical problems, this utility model utilizes the action of bevel gear two and bevel gear one in each set of clamping assemblies. Only one motor two is needed to achieve synchronous movement of multiple clamping plates. Furthermore, by setting multiple clamping slots and clamping plates, it can accommodate the clamping of multiple mechanical parts, achieving the purpose of grinding multiple parts in a single operation. The following technical solution achieves this:
[0006] This utility model is a mechanical parts grinding fixture, including a base, a processing table rotatably mounted on the top of the base, a plurality of clamping grooves are provided on the outer side of the top of the processing table, and a plurality of sets of clamping assemblies are slidably connected to the top of the processing table, and the clamping assemblies correspond one-to-one with the clamping grooves, and each set of clamping assemblies is rotatably connected to a flipping component.
[0007] The clamping assembly includes a clamping plate slidably connected to the processing table, and a second motor fixedly installed.

[0010] As a preferred embodiment of this utility model, a sliding key is fixedly installed on the hole wall of the clamping plate, and a sliding groove is formed on the surface of the screw, with the sliding groove slidably connected to the sliding key.
[0011] As a preferred technical solution of this utility model, the flipping assembly further includes a rotating shaft rotatably connected to the processing table, and a fixedly installed motor three, wherein the motor three is fixedly installed with the rotating shaft, and the rotating shaft is connected to the spline sleeve through a bevel gear set.
[0012] As a preferred technical solution of this utility model, the two spline sleeves in the flipping assembly are connected by a pulley and belt drive.

[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model utilizes the action of screws and clamping plates, along with the action of clamping plates and clamping slots, to achieve the purpose of clamping mechanical parts. Then, through the action of bevel gear two and bevel gear one in each set of clamping components, multiple clamping plates can be moved synchronously with only one motor two, which can reduce costs.

[0033] Example 1
[0034] Please see Figures 1-3 , Figure 5 As shown, this utility model is a mechanical parts grinding fixture, including a base 1, a processing table 2 rotatably mounted on the top of the base 1, ten clamping slots 5 are opened on the outer side of the top of the processing table 2, and ten sets of clamping assemblies 3 are slidably connected to the top of the processing table 2, and the clamping assemblies 3 correspond one-to-one with the clamping slots 5. The clamping assembly 3 includes a clamping plate 31 slidably connected to the processing table 2, and a motor 32 fixedly installed. A screw 33 is fixedly installed at the output end of the motor 32, and the screw 33 is rotatably connected to the processing table 2. The screw 33 is threadedly connected to the clamping plate 31. A sliding key 37 is fixedly installed on the hole wall of the clamping plate 31. A sliding groove 38 is opened on the surface of the screw 33, and the sliding groove 38 is slidably connected to the sliding key 37.
[0035] The mechanical part to be clamped is placed on the processing table 2, and one end of the part is pressed against the clamping groove 5. Then, the screw 33 is rotated by the motor 32. By using the sliding key 37 and the sliding groove 38, and by using the sliding action between the clamping plate 31 and the processing table 2, the clamping plate 31 moves closer to the axis of the processing table 2, clamping the other end of the mechanical part. Thus, the mechanical part to be polished can be clamped by the cooperation of the clamping groove 5 and the clamping plate 31.
[0036] To achieve simultaneous loading and unloading of multiple mechanical parts, please refer to [link / reference needed]. Figure 2 , Figure 3 , Figure 5 , Figure 8 , Figure 9 As shown, a specific application of this embodiment is as follows: an outer tube 36 is rotatably connected to the top of the base 1, a bevel gear 35 is fixedly installed on the outside of the outer tube 36, and a bevel gear 34 that meshes with the bevel gear 35 is fixedly installed at one end of the screw 33.
[0037] Through the interaction between bevel gear 2 35 and bevel gear 1 34 in each clamping assembly 3, when the screw 33 in one clamping assembly 3 rotates, it drives bevel gear 1 34 to rotate, which in turn drives bevel gear 2 35 to rotate, which in turn drives the outer tube 36 to rotate, thereby driving bevel gear 1 34 in the remaining nine clamping assemblies 3 to rotate, which in turn drives the screw 33 to rotate. This causes the ten clamping plates 31 to move synchronously toward the axis of the processing table 2, achieving synchronous clamping of multiple mechanical parts. This method is suitable for grinding multiple mechanical parts. Only one motor is needed to achieve synchronous movement of the clamping plates 31 in the ten clamping assemblies 3, thereby reducing the cost.
[0038] To prevent waste generated during the grinding of mechanical parts from falling onto the screw 33 via the slide groove on the processing table 2, thus affecting the transmission between the screw 33 and the clamping plate 31, a dustproof curtain can be connected between the slide groove and the clamping plate 31.
[0039] When grinding mechanical connections, please refer to Figure 3 , Figure 6 As shown, a specific application of this embodiment is as follows: a motor 6 is fixedly installed on one side of the top upper surface of the base 1, an eccentric wheel 7 is fixedly installed at the output end of the motor 6, a grooved wheel 8 is fixedly installed on the processing table 2, the grooved wheel 8 is slidably connected to the eccentric wheel 7, and the number of through grooves on the upper surface of the grooved wheel 8 corresponds one-to-one with the number of fixture assemblies 3.
[0040] Motor 6 drives eccentric wheel 7 to rotate. Each rotation of eccentric wheel 7 pushes grooved wheel 8 to rotate one-tenth of a revolution, which in turn causes processing table 2 to rotate one-tenth of a revolution, i.e., processing table 2 rotates one grinding station. When the mechanical part is rotated directly under the grinding equipment, the grinding equipment grinds the part while eccentric wheel 7 is rotating and not pushing grooved wheel 8 to rotate. After grinding, eccentric wheel 7 rotates one revolution again. At this time, grooved wheel 8 and processing table 2 rotate one-tenth of a revolution again, rotating the mechanical part at the second station directly under the grinding equipment, and then grinding the mechanical part. The above operation is repeated until all ten mechanical parts are completely ground. When all parts are ground, motor 32 reverses screw 33, which then pushes clamping plate 31 away from the axis of processing table 2, releasing the clamping of the parts. Then the ground mechanical parts are removed from processing table 2 for clamping of the next mechanical parts.
[0041] Example 2
[0042] To ensure thorough grinding of all parts during the grinding process, please refer to [link / reference needed]. Figures 3-5 , Figures 7-9 As shown, a specific application of this embodiment is as follows: each set of clamping components 3 is rotatably connected to a flipping component 4. The flipping component 4 includes two splined shafts 46 rotatably connected to the clamping plate 31, and two splined sleeves 45 rotatably connected to the processing table 2. The splined shafts 46 and splined sleeves 45 cooperate with each other. Rubber rollers 47 are fixedly installed on the surfaces of the splined shafts 46 and splined sleeves 45. The flipping component 4 also includes a rotating shaft 42 rotatably connected to the processing table 2, and a fixedly installed motor 43. The motor 43 is fixedly installed with the rotating shaft 42. The rotating shaft 42 is connected to the splined sleeves 45 through a bevel gear set. The two splined sleeves 45 in the flipping component 4 are connected by a pulley and a belt drive.
[0043] The motor 43 drives the rotating shaft 42 to rotate, and the rotating shaft 42 drives one of the spline sleeves 45 to rotate through the bevel gear set. The spline sleeve 45 and the spline shaft 46 drive the rubber roller 47 and the mechanical parts on it to rotate, thereby turning the mechanical parts over. In order to make the two spline sleeves 45 rotate synchronously, the two spline sleeves 45 can be driven by pulleys and belts, thereby driving the other spline sleeve 45 and the rubber roller 47 on the spline shaft 46 to rotate, thereby fully polishing the outer surface of the parts.
[0044] To reduce the number of motors used in each set of flipping components 4, please refer to Figures 2-5 , Figure 7As shown, a specific application of this embodiment is as follows: the top of the base 1 is rotatably connected to an inner tube 48, the inner tube 48 is sleeved on the outer side of the bottom of the processing table 2, and the outer tube 36 is sleeved on the outer side of the inner tube 48. A spur gear 41 is fixedly installed on the surface of the inner tube 48, and a spur gear 44 that meshes with the spur gear 41 is fixedly installed on the outer side of the rotating shaft 42.
[0045] When the rotating shaft 42 in one of the sets of flipping components 4 rotates, the action of the first spur gear 41 and the second spur gear 44 in each set of flipping components 4 drives the rotating shaft 42 in the other nine sets of flipping components 4 to rotate, so that the spline sleeve 45 in the ten sets of flipping components 4 rotates synchronously. Furthermore, with the use of the motor, during the grinding process of mechanical parts, the spline sleeve 45 in the ten sets of flipping components 4 is always in a rotating state, without the need for frequent starting and stopping of the motor, which can reduce the wear of the motor.
