[0002] A surface grinder is generally used to grind the horizontal surface of a workpiece. It primarily uses a rotating grinding wheel to grind the workpiece surface to achieve the required flatness. Its structure typically includes a worktable mounted on the machine bed, a grinding head with a grinding wheel structure mounted above the worktable, and the grinding head being mounted on the machine bed via a support and movement device on one side of the worktable. A clamping and fixing device is also provided on the worktable to hold and fix the workpiece to be ground.

[0003] When grinding aluminum base workpieces, due to the small size and large number of aluminum bases, if the grinding method is used to grind them one by one, it will not only be time-consuming and labor-intensive, but the grinding efficiency will still be low. Moreover, the workload of this purely manual operation method will increase dramatically, resulting in a high labor intensity for the grinding operation. Utility Model Content

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments are not intended to limit the present invention.

[0023] Reference Figure 1 , 2 As shown, the batch pressing grinding fixture of this utility model includes: a base 1; a lower support plate 2, which is mounted on the base 1 and is used to support the workpiece to be processed; a support frame 3, which is mounted on the base 1; a fixed mounting plate 5, which is mounted on the base 1, and the fixed mounting plate 5 and the support frame 3 are respectively located on opposite sides of the lower support plate 2; a pressing assembly 4, which is mounted on the support frame 3 and the fixed mounting plate 5, and is used to press the workpiece to be processed on the lower support plate 2; and a pushing power source 6, which is mounted on the fixed mounting plate 5, and the pushing power source 6 is connected to a plurality of push rods 7, which are used to drive the plurality of push rods 7 to push the workpiece to be processed on the lower support plate 2 into contact with the side wall of the support frame 3.

[0024] In the above structure, the lower support plate 2, support frame 3, and fixed mounting plate 5 form a U-shaped structure. The support frame 3 and fixed mounting plate 5 are respectively located on both sides of the lower support plate 2 and are positioned opposite each other. A stack of workpieces to be processed can be placed within the U-shaped area formed by the lower support plate 2, support frame 3, and fixed mounting plate 5. By driving several push rods 7 through the push power source 6, the stack of workpieces to be processed is pushed until it contacts the side wall of the support frame 3, thereby aligning the stack of workpieces. Specifically, the end face of the support frame 3 opposite to the fixed mounting plate 5 is provided with an inclined surface 31. While the push rods 7 push the workpieces to abut against the small plane of the support frame 3, their inclined surface 31 simultaneously contacts the inclined surface of the workpieces, thereby fully positioning the workpieces.

[0025] Reference Figure 3 As shown, the pushing power source 6 is a hydraulic cylinder. The output end of the pushing power source 6 is connected to the fixed mounting plate 5. A T-shaped plate 61 is connected to the outer wall of the pushing power source 6. One end of the push rod 7 passes through the T-shaped plate 61, and the push rod 7 is floatingly connected to the T-shaped plate 61. Several push rods 7 are arranged in a row, and each push rod 7 corresponds to a stack of workpieces to be processed. The pushing power source 6 drives the T-shaped plate 61 forward. During the forward movement of the T-shaped plate 61, the pushing force is transmitted to the push rods 7 to push the push rods 7 to move. When the pushing power source 6 drives several push rods 7 to move synchronously, the push rod 7 can push the corresponding workpiece to be processed until it contacts the inclined surface 31.

[0026] In the above structure, a spring 71 is fitted onto the push rod 7. Both ends of the spring 71 abut against the T-shaped plate 61 and the push rod 7, respectively. Specifically, a limiting plate is provided at the end of the push rod 7 furthest from the fixed mounting plate 5. One end of the spring 71 abuts against the side wall of the T-shaped plate 61, and the other end of the spring 71 abuts against the limiting plate. The main function of the spring 71 is to force the push rod 7 forward, achieving floating positioning of the workpiece. The spring's function allows the positioning rod 7 to achieve floating positioning of the workpiece, compensating for dimensional differences in the workpiece itself.

[0027] In the above structure, a guide rod 62 is connected to the fixed mounting plate 5, and a linear bearing is installed on the T-shaped plate 61. The guide rod 62 passes through the linear bearing and can slide along the linear bearing, thereby realizing the linear sliding of the guide rod. The fixed mounting plate 5 is provided with a guide post mounting hole 51. One end of the guide rod 62 is installed in the guide post mounting hole 51. The T-shaped plate 61 is installed with a linear bearing, and the guide rod 62 passes through the linear bearing, thereby causing the T-shaped plate 61 to drive the pusher power source 6 to move along the axial direction of the guide rod 62. The fixed mounting plate 5 is also provided with several guide holes 52. A finely ground guide sleeve is installed in the guide hole 52. Several push rods 7 are arranged one-to-one with several guide holes 52. The push rods 7 pass through the finely ground guide sleeves and can slide along the finely ground guide sleeves.

[0028] Reference Figure 3 As shown, the pressing assembly 4 includes a support beam 40, a pressing power source 41, and a pressing plate 42. The two ends of the support beam 40 are respectively mounted on the upper ends of the support frame 3 and the fixed mounting plate 5. The pressing power source 41 is fixedly mounted on the support beam 40. The pressing plate 42 is connected to the output end of the pressing power source 41, and the pressing plate 42 is located directly above the lower support plate 2. The pressing power source 41 is preferably a hydraulic cylinder.

[0029] In the above structure, the lower pressure plate 42 and the lower support plate 2 have an upper limit boss 421 on their opposite end faces, which is used to limit the position of the workpiece to be processed. The upper end face of the cooperating lower support plate 2 has a lower limit boss 21, which is used to limit the position of the workpiece to be processed. The upper limit boss 421 and the lower limit boss 21 respectively position the workpiece from the upper and lower ends of the workpiece to be processed. Preferably, this utility model is applicable to workpieces with grooves on both the upper and lower surfaces. The upper limit boss 421 and the lower limit boss 21 are rectangular blocks, and the two long sides of the upper limit boss 421 and the lower limit boss 21 are both set as inclined surface structures. The inclined surface structures on both sides of the upper limit boss 421 and the lower limit boss 21 play an auxiliary role in positioning the workpiece.

[0030] In the above structure, the lower pressure plate 42 is connected to a second guide post 422, and the supporting beam 40 is provided with a guide sleeve 43. The second guide post 422 and the guide sleeve 43 are slidably connected. The second guide post 422 is cylindrical. Preferably, the number of second guide posts 422 is set to four, and the number of cooperating guide sleeves 43 is also four. The four guide sleeves 43 and the four second guide posts 422 are arranged in a one-to-one correspondence. The cross-section of the lower pressure plate 42 is rectangular, and the four second guide posts 422 are respectively located at the four corners of the lower pressure plate 42, thus ensuring the stability of the lower pressure plate 42 during movement.

[0031] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
