Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a jig with an adjustable head for shaft rod processing. Background Technique

[0002] Shaft rods are components that must be used in many mechanical devices. According to the characteristics of the shaft rods required by different devices, they are cut, polished, turned, stamped, etc. to enable them to provide the required effects during the operation of the devices.

[0003] In the traditional processing of shaft rods, there is a way that both ends need to be processed. The traditional treatment is to clamp the shaft rod with a jig. After one end is processed, the jig is loosened, the shaft rod is turned around, and then it is clamped again by the jig, and finally the other end is processed.

[0004] The inventor found that the following problems in the prior art were not well solved during the implementation of this solution: Although the operation is simple, there are many steps, and the efficiency cannot be improved. Moreover, after turning around, the position from the processed end to the end of the processing equipment needs to be recalibrated, which wastes time. And manually adjusting the jig repeatedly will also reduce the work efficiency. Content of the Utility Model

[0005] The main purpose of the utility model is to provide a jig with an adjustable head for shaft rod processing, which can effectively solve the problems in the background technique.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An adjustable-head fixture for shaft rod processing, comprising an L-shaped seat. A first gear, a second gear and a third gear are respectively rotatably connected to the top of the L-shaped seat. The first gear meshes with the third gear, and the third gear meshes with the second gear. Above the L-shaped seat between the first gear, the second gear and the third gear, a first gantry is fixed. Inside the first gantry at the position of the first gear, a motor is fixed. Inside the first gantry at the position of the second gear, a hydraulic rod is fixed. The output end of the motor is fixed with a shaft body, and the bottom of the shaft body is fixed to the top of the first gear. The telescopic end of the hydraulic rod is fixed with a second gantry. A seat body is fixed to the top of the second gear. At both ends of the top of the seat body, lower V-shaped seats are fixed. An upper V-shaped seat is arranged between the lower V-shaped seats. At the position of the upper V-shaped seat, the second gantry is threadedly connected with an adjusting screw rod, and the bottom of the adjusting screw rod is rotatably connected to the top of the upper V-shaped seat. At the rear end of the L-shaped seat at the position of the seat body, a slide rail is fixed. At one end of the slide rail close to the seat body, a first slider is slidably connected. At one end of the slide rail far from the seat body, a second slider is slidably connected. A baffle is fixed to the top of the second slider. At both ends of the inside of the slide rail, ear grooves are dug. On the side walls of the first slider at the position of the ear grooves, screw rods are fixed, and nuts are threadedly connected to the outer walls of the screw rods.

[0008] Preferably, at the four corners of the top of the upper V-shaped seat, slide rods are fixed, and the slide rods respectively penetrate through the second gantry and are slidably connected.

[0009] Preferably, at the four corners of the bottom of the second gantry, pressure rods are fixed, and at the bottoms of the pressure rods, first inclined blocks are fixed.

[0010] Preferably, at both ends of the side walls of the seat body, second inclined blocks are fixed, and the inclined surfaces of the first inclined blocks are respectively in contact with the inclined surfaces of the second inclined blocks with matching positions.

[0011] Preferably, the screw rods respectively penetrate through and communicate with the ear grooves, and the nuts are respectively located outside the ear grooves.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. By using the motor, the first gear, the shaft body, the second gear, the third gear, the seat body and the hydraulic rod in cooperation, after the lower V-shaped seat and the upper V-shaped seat clamp the shaft rod and complete the processing of one end, they can automatically turn the head and process the other end of the shaft rod. This method does not require manual adjustment of the fixture and the shaft rod, saves time, speeds up the working efficiency of single-piece processing, and the rotation of the adjusting screw rod can adjust the initial clamping height of the upper V-shaped seat, so that the upper V-shaped seat and the lower V-shaped seat can stably clamp shaft rods of more sizes.

[0014] 2. Before the shaft rod is clamped and processed by the upper V seat and the lower V seat, the center position calibration effect can be achieved by abutting against the baffle. After the calibration is completed and the clamping is completed, the baffle can slide at the rear end of the slide rail through the second slider, avoiding affecting the rotation during its turning. The position where the second slider slides close to the seat body in the slide rail is the key to calibrating the center position of the shaft rod processing. The stop position of its movement can be limited by the threaded connection between the screws at both ends of the first slider passing through the ear slots and the nuts, so that the second slider can stop according to the center position of workpieces in different batches when moving.

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-4As shown in the figure, a fixture with an adjustable head for shaft rod processing includes an L-shaped seat 1. At the top of the L-shaped seat 1, a first gear 5, a second gear 6, and a third gear 7 are respectively rotatably connected. The first gear 5 meshes with the third gear 7, and the third gear 7 meshes with the second gear 6. Above the L-shaped seat 1 between the first gear 5, the second gear 6, and the third gear 7, a first gantry 2 is fixed. At the inner top of the first gantry 2 at the position of the first gear 5, a motor 3 is fixed. At the inner top of the first gantry 2 at the position of the second gear 6, a hydraulic rod 4 is fixed. The output end of the motor 3 is fixed with a shaft body 51, and the bottom of the shaft body 51 is fixed to the top of the first gear 5. The telescopic end of the hydraulic rod 4 is fixed with a second gantry 41. A seat body 8 is fixed to the top of the second gear 6. At both ends of the top of the seat body 8, lower V-shaped seats 9 are fixed. Between the lower V-shaped seats 9, an upper V-shaped seat 91 is provided. At the position of the upper V-shaped seat 91, the second gantry 41 is threadedly connected with an adjusting screw 11, and the bottom of the adjusting screw 11 is rotatably connected to the top of the upper V-shaped seat 91. At the rear end of the L-shaped seat 1 at the position of the seat body 8, a slide rail 10 is fixed. At one end of the slide rail 10 close to the seat body 8, a first slider 101 is slidably connected. At the other end of the slide rail 10 away from the seat body 8, a second slider 1011 is slidably connected. A baffle 102 is fixed to the top of the second slider 1011. At both ends of the inner part of the slide rail 10, ear slots 103 are drilled. On the side walls of the first slider 101 at the positions of the ear slots 103, screws 104 are fixed, and nuts 105 are threadedly connected to the outer walls of the screws 104.

[0022] Specifically, at the four corners of the top of the upper V-shaped seat 91, slide rods 12 are fixed. The slide rods 12 respectively penetrate through the second gantry 41 and are slidably connected, making the movement of the upper V-shaped seat 91 more vertical during adjustment.

[0023] Specifically, at the four corners of the bottom of the second gantry 41, pressure rods 13 are fixed. At the bottom of the pressure rods 13, first inclined blocks 14 are fixed. At both ends of the two side walls of the seat body 8, second inclined blocks 15 are fixed. The inclined surfaces of the first inclined blocks 14 are respectively in contact with the inclined surfaces of the second inclined blocks 15 that match in position. When the upper V-shaped seat 91 descends under the traction after the hydraulic rod 4 works, the contact between the two inclined surfaces can make the upper V-shaped seat 91 and the lower V-shaped seat 9 clamp the shaft rod more stably, ensuring the stability during processing.

[0024] Specifically, the screws 104 respectively penetrate through and communicate with the ear slots 103, and the nuts 105 are respectively located outside the ear slots 103, which can fix the position of the first slider 101 and make it play an effect of calibrating and stopping when the second slider 1011 moves.

[0025] Working principle: The motor 3 drives the gear 5 to rotate through the shaft body 51. The gear 5 drives the gear 2, the seat body 8, and the lower V seat 9 to rotate through the gear 3, so as to realize the turning work after one end of the processing is completed. After the hydraulic rod 4 works, it drives the upper V seat 91 to lift and lower, enabling the fixture to complete the loosening and clamping work, which is convenient for disassembling and assembling the shaft rod. This method does not require manual adjustment of the fixture and the shaft rod, saving time and accelerating the working efficiency of single-piece processing. The rotation of the adjusting screw 11 can adjust the initial clamping height of the upper V seat 91, so that the upper V seat 91 and the lower V seat 9 can stably clamp shaft rods of more sizes. Before the shaft rod is clamped and processed by the upper V seat 91 and the lower V seat 9, the center position can be calibrated by abutting against the baffle 102. After the calibration and clamping are completed, the baffle 102 can slide at the rear end of the slide rail 10 through the slider 2 1011, avoiding affecting its rotation during turning. The position where the slider 2 1011 slides in the slide rail 10 close to the seat body 8 is the key to calibrating the center position of the shaft rod processing. The stop position of its movement can be limited by the threaded connection of the screw 104 at both ends of the slider 1 101 passing through the ear slot 103 and the nut 105, so that the slider 2 1011 can stop according to the center position of workpieces in different batches when moving.
