Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a mechanical processing fixing jig which is convenient to use. Background Art

[0002] A mechanical processing fixing jig is a tool used to clamp a workpiece to ensure its stability during the mechanical processing. The fixing jig usually consists of components such as a jig base, jig arms, and jig jaws, and ensures that the workpiece does not move or shake during processing by adjusting the position and clamping force of the jig.

[0003] In the utility model patent with the patent authorization announcement number CN220575295U, a mechanical processing fixing jig is disclosed, including a base; a pair of vertical plates are provided on the top of the base; a group of through holes are provided on the side walls of the pair of vertical plates; a thick rod is slidably connected to the through holes; a clamping member is provided at one end of each group of thick rods; a first chute is formed at the other end of the thick rod; a thin rod is slidably connected in the first chute; a pair of thick rods are fixedly connected with a push plate through a spring; a pair of the push plates are distributed on both sides of the base; a first motor is fixedly connected to the top of the base; a transmission member is provided at the output end of the first motor; the push plate is driven by the transmission member; to solve the problem that when clamping an original part with an irregular shape, due to the fixed angle of the clamping device, it is impossible to fit the surface of the clamping member, greatly reducing the contact area between the clamping device and the clamped part, resulting in a significant reduction in the clamping ability; and even causing the clamping member to fall during the processing, creating a safety hazard.

[0004] However, the existing mechanical processing fixing jigs also have certain deficiencies. First of all, although the existing mechanical processing fixing jigs use the cooperation of structures such as air cylinders and clamping plates to complete the clamping and fixing of workpieces, due to the influence of factors such as material friction between the cylinder body and the telescopic end, the telescopic resistance of the air cylinder will be large after long-term use;

[0005] Secondly, when the existing mechanical processing fixing jigs are used, clamping plates in a fixed orientation are mostly used to clamp and fix workpieces. Due to factors such as the difference in the placement position of the workpieces, operators need to continuously manually adjust the orientation, which is obviously not convenient to use. Therefore, the existing technology needs to be improved. Summary of the Utility Model

[0006] The present utility model provides a mechanical processing fixing fixture that is convenient to use, which solves the problem that although the existing mechanical processing fixing fixture uses a combination of structures such as a cylinder and a clamping plate to complete the clamping and fixing of a workpiece, due to the influence of the material friction factor between the cylinder body and the telescopic end, the telescopic resistance of the cylinder will be large after long-term use; and it also solves the technical problem that when the existing mechanical processing fixing fixture is used, clamping plates in a fixed orientation are mostly used to clamp and fix the workpiece. Due to factors such as the difference in the placement position of the workpiece, the operator needs to continuously manually adjust the orientation, which is not convenient to use.

[0007] To solve the above technical problems, a mechanical processing fixing fixture that is convenient to use provided by the present utility model includes a support plate. Two symmetrically distributed handles are fixedly connected to the upper end of the support plate. A support shaft is installed inside the support plate through a bearing. The lower end of the support shaft is fixedly connected to a support frame. A chute is provided in the horizontal part of the support frame. A cylinder is fixedly installed in the vertical part of the support frame. The telescopic end of the cylinder is fixedly connected to a clamping plate. The clamping plate is slidably connected to the chute. A rotating mechanism is jointly provided on the support plate and the support shaft. A lubricating mechanism is provided on the support frame.

[0008] Preferably, the rotating mechanism includes a first gear. The first gear is fixedly sleeved on the outer side of the support shaft. A servo motor is fixedly installed on the left side of the upper end of the support plate. The output shaft of the servo motor is rotatably connected to the support plate. A second gear is fixedly sleeved on the outer side of the output shaft of the servo motor. The second gear meshes with the first gear. A rotating column is fixedly sleeved on the outer side of the output shaft of the servo motor and above the second gear. The rotating column is rotatably connected to the support plate. Through the setting of structures such as the servo motor and the second gear, the first gear can be driven to rotate, so as to drive the support shaft to rotate, and then drive the support frame to rotate, adjust the position of the clamping plate, and improve the adaptability of the clamping of the clamping plate.

[0009] Preferably, two symmetrically distributed limiting pieces are fixedly connected to the lower end of the support plate. Each limiting piece contacts the rotating column. Through the setting of the limiting pieces, rotational limiting treatment can be performed on the rotating column.

[0010] Preferably, the lubrication mechanism includes an oil storage box. The horizontal part of the support frame is fixedly connected with the oil storage box. A diversion pipe is fixedly connected inside the oil storage box. The diversion pipe is fixedly connected with the horizontal part of the support frame. An oil absorption sleeve is fixedly sleeved outside the diversion pipe. A terminal rod is slidably connected inside the oil storage box. A sealing plate is fixedly connected to the lower side of the terminal rod. The sealing plate is slidably connected with the diversion pipe and the oil storage box. A moving disk is fixedly sleeved outside the terminal rod. A spring is arranged outside the terminal rod. By pulling the terminal rod to move away from the clamping plate, the sealing plate is driven to move, and the spring deforms. Eventually, the sealing plate disengages from the diversion pipe. Under the action of the diversion pipe, the lubricating oil can be diverted, and finally the lubricating oil contacts the oil absorption sleeve, thereby lubricating the telescopic end of the cylinder to reduce the telescopic resistance of the cylinder.

[0011] Preferably, the oil absorption sleeve contacts the end face of the cylinder and is slidably connected with the telescopic end of the cylinder. Through the setting of the oil absorption sleeve, the lubricating oil can be adsorbed.

[0012] Preferably, one end of the spring is welded to the moving disk, and the other end of the spring is welded to the oil storage box. Through the setting of the spring, the moving disk can be connected for use.

The second gear 83 meshes with the first gear 81. A rotating column 84 is fixedly sleeved on the outside of the output shaft of the servo motor 82 and above the second gear 83. The rotating column 84 is rotatably connected to the support plate 1. Two symmetrically distributed limiting pieces 85 are fixedly connected to the lower end of the support plate 1. Each limiting piece 85 contacts the rotating column 84. Through the arrangement of the limiting pieces 85, rotational limiting treatment can be carried out on the rotating column 84.

[0023] Please refer to Figure 1 , Figure 2, Figure 3 , Figure 4 , on the support frame 4, a lubricating mechanism 9 is provided. The lubricating mechanism 9 includes an oil storage box 91. The horizontal part of the support frame 4 is fixedly connected with the oil storage box 91. Inside the oil storage box 91, a diversion pipe 92 is fixedly connected. The diversion pipe 92 is fixedly connected with the horizontal part of the support frame 4. An oil absorption sleeve 93 is fixedly sleeved on the outside of the diversion pipe 92. A terminal rod 94 is slidably connected inside the oil storage box 91. A sealing plate 95 is fixedly connected to the lower side of the terminal rod 94. The sealing plate 95 is slidably connected with the diversion pipe 92 and the oil storage box 91. A moving plate 96 is fixedly sleeved on the outside of the terminal rod 94.
