Technical Field

[0001] The invention relates to the technical field of tooling fixtures, and in particular to an automatic clamping device for lathe processing of a roller body. Background Art

[0002] In the field of mechanical processing, roller body is a common mechanical component, which is widely used in various mechanical equipment, such as conveying systems. The design and processing quality of the roller body directly affect the operating efficiency and stability of the mechanical equipment. Figure 1 As shown, in order to ensure that the roller can be installed, it is usually necessary to drill a through hole on the side wall of the bottom groove of the roller body.

[0003] Existing roller body processing technology mainly relies on traditional fixtures and manual operation. These fixtures usually include a fixed base, a clamping mechanism and a positioning mechanism. During the processing process, the operator needs to manually place the roller body on the fixture, ensure its position is accurate through the positioning mechanism, and then manually operate the clamping mechanism to fix the roller body for drilling and other processing operations. However, the manual clamping process is time-consuming and inefficient, especially in mass production. This low efficiency will significantly increase production costs. Moreover, due to its reliance on manual operation, it is difficult to maintain consistent clamping force on the roller body, which may cause errors in the processing process and affect product quality. This also reflects that the operation of the fixture requires the operator to have certain skills and experience to ensure the correct installation and fixation of the roller body, thereby increasing the complexity of the operation and the requirements for operator skills.

[0016] like Figures 2 to 4As shown, an automatic clamping device for roller body lathe processing, a base 1, a positioning groove 3 for placing a workpiece 2, a positioning flat pin 4 for inserting into the bottom end groove of the workpiece 2 and a clamping mechanism for clamping the workpiece 2 are provided on the base 1, a positioning flat pin through hole 5 corresponding to the drilling station of the workpiece 2 is opened on the positioning flat pin 4, and the clamping mechanism includes a pressing plate 6a for pressing on the workpiece 2, a driving rod 6b hinged to one end of the pressing plate 6a, and a support rod 6c respectively hinged to the middle of the pressing plate 6a and the base 1, the bottom end of the driving rod 6b passes through the base 1 and is connected to a transmission arm 6d, and the transmission arm 6d is arranged on the base 1, the middle part of the transmission arm 6d is hinged to the groove 7, one end of the transmission arm 6d extends to the center of the bottom of the base 1 and is hinged to the piston rod of the cylinder; when the piston rod of the cylinder moves downward, it can pull the transmission arm 6d to make its top end move upward, thereby pushing the driving rod 6b to move upward, and then lifting one end of the pressing plate 2 so that the other end of the pressing plate 2 is pressed tightly on the workpiece 2; when the piston rod of the cylinder moves upward, it can push the transmission arm 6d to make its top end move downward, thereby pulling the driving rod 6b to move downward, and then pulling one end of the pressing plate 2 so that the other end of the pressing plate 2 is lifted from the workpiece 2.

[0017] In the above structure, the transmission arm 6d is tiltedly arranged in the groove 7, a support 8 for the transmission arm 6d to pass through is fixedly installed in the groove 7, and the middle part of the transmission arm 6d is hinged to the support 8.

[0018] Preferably, the base 1 is detachably mounted with a first fixing block 9, and the positioning groove 3 is a V-shaped groove provided on the top surface of the first fixing block 9. One end of the fixing block 9 extends below the positioning flat pin through hole 5 and is correspondingly provided with a positioning groove through hole 10. The detachable design allows the first fixing block 9 to be quickly replaced according to different processing requirements, thereby improving the flexibility and adaptability of the equipment and facilitating the processing of roller bodies of different specifications.

[0019] In addition, a second fixing block 11 is detachably mounted on the base 1. The second fixing block 11 is provided with a horizontal through hole. One end of the positioning flat pin 4 is inserted into the horizontal through hole. A locking bolt for locking the positioning flat pin 4 is passed downward from the top of the second fixing block 11.

[0020] Furthermore, the other end of the positioning flat pin 4 is provided with a head structure for inserting into the bottom end groove of the workpiece 2, the outer end surface of the head structure is set as an arc end surface matching the bottom surface of the groove of the bottom end groove of the workpiece 2, and the upper and lower end surfaces of the head structure are also respectively provided with guide wedge blocks 4a for easy insertion into the bottom end groove of the workpiece 2, and the positioning flat pin through hole 5 is located in the head structure.

The cylinder is started to move the piston rod of the cylinder downward, and the pressure plate 6a is pulled by the transmission arm 6d and the driving rod 6b, so that one end of the pressure plate 6a is lifted up and the other end is pressed on the workpiece 2, and then the drilling tool on the lathe is started and rotated at high speed. The lathe can achieve feed by driving the clamping device to move or by allowing the drilling tool to move while rotating, thereby completing the drilling process. After the processing is completed, the cylinder is started to move the piston rod upward, and the transmission arm 6d and the driving rod 6b move accordingly, and the pressure plate 6a is lifted from the workpiece 2, so that the workpiece 2 withdraws from the cooperation with the positioning flat pin 4 and is taken out of the positioning groove 3.

[0022] The principle of the present invention is to use an automated clamping mechanism to drive the transmission arm and the driving rod through a cylinder to achieve automatic clamping and release of the roller body, thereby replacing the traditional manual operation. The device accurately positions the roller body through the positioning groove and the positioning flat pin on the base to ensure stability and accuracy during the processing.
