Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of axle housing, in particular to a novel adjustable clamping device. BACKGROUND

[0002] At present, the same industry adopts the mode that the screw rod controls the clamping block to clamp the axle housing, and the clamping and loosening of the clamping block need manual rotation of the screw rod to adjust the clamping block to the position, which not only is time-consuming and laborious, but also when the manual adjustment of the screw rod is not in place, the axle housing cannot be in the correct clamping state, and the safety risk is easy to produce in the subsequent assembly process.

[0003] The existing online clamping device of the axle assembly assembly is manually adjusted, and if the adjustment is not in place, the axle assembly is at risk of overturning and falling during the assembly process, which affects the safety of the workers during the assembly process. If the manual adjustment of the screw rod is not in place, the axle housing cannot be in the correct clamping state, and at this time, the axle housing has no reaction point during the torque process, and the axle assembly is easy to overturn due to the gravity and inertia of the main reducer assembly, which is easy to cause the risk of personnel bumping or the axle assembly falling. Moreover, at the present stage, the manual adjustment of the clamping device affects the process rhythm and reduces the work efficiency of the workers. UTILITY MODEL CONTENTS

[0004] The utility model provides a novel adjustable clamping device, which solves the problem that the axle assembly cannot be quickly and accurately clamped during online assembly.

[0005] The technical scheme of the utility model is as follows:

[0006] A novel adjustable clamping device, comprising a device base body, a cavity is formed in the inside of the device base body, openings are formed in the left and right sides of the device base body, the openings are communicated with the cavity, clamping blocks are slidably connected to the left and right ends of the top of the device base body, the two clamping blocks slide relative to each other, a through hole is formed in the middle of the top of the device base body, a middle shaft is vertically inserted into the through hole, a sliding sleeve is movably sleeved on the lower end of the middle shaft, large connecting rods are hingedly connected to the left and right sides of the sliding sleeve, a double-ear hydraulic oil cylinder is hingedly connected between the lower ends of the two large connecting rods, small connecting rods are hingedly connected to the upper ends of the two large connecting rods, and the two small connecting rods are hingedly connected to the two clamping blocks respectively.

[0007] Through the above technical solution, the cooperation of the large connecting rod, small connecting rod, and hydraulic connecting rod assembly allows the upper ends of the two large connecting rods to move towards each other simply by activating the hydraulic connecting rod assembly. When the two large railings approach each other, the small connecting rod drives the two clamping blocks to move towards each other, thereby clamping and fixing the end of the bridge housing located between the two clamping blocks. The design of the sliding sleeve and intermediate shaft improves the stability of the movement of the large connecting rods and prevents the large and small connecting rods from shifting or overturning when driving the clamping blocks. The entire clamping process is fast and improves clamping efficiency.

[0008] Optionally, guide blocks are fixedly connected to both the left and right ends of the top of the device base. The guide blocks are provided with guide grooves. The sides of the guide grooves are isosceles trapezoidal. The clamping blocks are slidably connected in the guide grooves.

[0009] Through the above technical solution, the setting of guide blocks and guide grooves makes the movement of clamping blocks accurate and stable, further improving the stability and firmness of clamping the end of the bridge housing when the clamping blocks move towards each other.

[0010] Optionally, the clamping block includes an upper clamping block and a lower slider. The lower slider is strip-shaped, and the side of the lower slider is an isosceles trapezoid. The lower slider is in clearance fit with the guide groove. The top of the lower slider is fixedly connected to the bottom of the upper clamping block. The upper clamping block is rectangular and integrally connected with the lower slider.

[0011] Through the above technical solution, the design of the upper clamping block and the lower sliding block can improve the firmness of the upper end of the clamping block clamping the bridge housing, and also improve the stability of the lower end of the clamping block moving back and forth.

[0012] Optionally, the longitudinal section of the through hole is T-shaped, the intermediate shaft is T-shaped, and the lower end of the intermediate shaft extends vertically through the through hole into the cavity.

[0013] Through the above technical solution, the shape design of the through hole and the intermediate shaft can improve the stability of the intermediate shaft in the through hole and avoid collision or unevenness after the bridge housing is placed on the top of the device base.

[0014] Optionally, the two large connecting rods are connected to the double-eared hydraulic cylinder in a U-shape. Each large connecting rod includes a bent rod and a straight rod. The upper end of the bent rod is hinged to the end of the small connecting rod, and the lower end of the bent rod is hinged to the end of the double-eared hydraulic cylinder. A straight rod is fixedly connected to the inner side of the bent rod, and the end of the straight rod is fixedly connected to the non-bent part of the bent rod. The straight rod and the bent rod are integrally connected. The sliding sleeve, the straight rod, the lower end of the bent rod, and the double-eared hydraulic cylinder are all located in the cavity.

[0015] Through the above technical solution, the lower curved rod can move flexibly during the entire clamping and retraction process of the connecting rod, avoiding interference with the base. The straight rod can smoothly drive the sliding sleeve to slide up and down during the movement of the connecting rod. The arc shape of the lower part of the connecting rod can not only avoid the potential for injury to the human body caused by the right angle structure during the movement, but also make the movement smoother.

[0016] Optionally, the straight rod and the bent rod are integrally connected.

[0017] After adopting the above technical solution, the beneficial effects of this utility model are:

[0018] The clamping device in this invention uses the outer end face of the square cross-section of the axle housing as a limit to prevent the axle housing assembly from flipping or shifting, which would affect the assembly of subsequent components. Automatic clamping is achieved through connecting rods and hydraulic rods, ensuring that the axle assembly will not flip or fall during assembly, thus not affecting subsequent assembly. The connecting rod and hydraulic rod structure is easy to operate, saving time and effort, and greatly improving operational safety. This clamping device controls the movement of each connecting rod through hydraulic rods, making the adjustment of the clamping blocks simple and convenient, resulting in high work efficiency. The clamping device uses a self-weight connecting sleeve to achieve automatic workpiece clamping, saving time and effort and increasing work efficiency. Attached Figure Description

[0027] This application discloses a novel adjustable clamping device.

[0028] Example

[0029] according to Figures 1 to 5 As shown, a novel adjustable clamping device includes a device base 1, with a cavity 2 inside the device base 1. Openings are provided on both the left and right sides of the device base 1, and the openings communicate with the cavity 2. Guide blocks 10 are fixedly connected to the left and right ends of the top of the device base 1. Guide blocks 10 have guide grooves, and the sides of the guide grooves are isosceles trapezoidal. Clamping blocks 3 are slidably connected in the guide grooves. The two clamping blocks 3 slide relative to each other. The clamping blocks 3 include an upper clamping block 11 and a lower slider 12. The lower slider 12 is strip-shaped, and the sides of the lower slider 12 are isosceles trapezoidal. The lower slider 12 is clearance-fitted with the guide groove. The top of the lower slider 12 is fixedly connected to the bottom of the upper clamping block 11. The upper clamping block 11 is rectangular, and the upper clamping block 11 and the lower slider 12 are integrally connected.

[0030] A through hole 4 is provided in the middle of the top of the device base 1. The through hole 4 is located between the two guide blocks 10. An intermediate shaft 5 is vertically inserted into the through hole 4. The intermediate shaft 5 is fixed in the through hole 4 and cannot move. The longitudinal section of the through hole 4 is T-shaped. The intermediate shaft 5 is also T-shaped. The lower end of the intermediate shaft 5 extends vertically through the through hole 4 into the cavity 2. A sliding sleeve 6 is movably sleeved on the outer side of the lower end of the intermediate shaft 5. Large connecting rods 7 are hinged to both the left and right sides of the sliding sleeve 6. The lower ends of the two large connecting rods 7 are movably connected to double-ear hydraulic cylinders 9. Small connecting rods 8 are hinged to the upper ends of the large connecting rods 7. The end of the small connecting rod 8 away from the large connecting rod 7 is hinged to the side of the clamping block 3.

[0031] Two large connecting rods 7 are connected to the double-eared hydraulic cylinder 9 in a U-shape. The large connecting rods 7 include a bent rod 13 and a straight rod 14. The upper end of the bent rod 13 is hinged to the end of the small connecting rod 8, and the lower end of the bent rod 13 is hinged to the end of the double-eared hydraulic cylinder 9. A straight rod 14 is fixedly connected to the inner side of the bent rod 13, and the end of the straight rod 14 is fixedly connected to the non-bent part of the bent rod 13. The straight rod 14 and the bent rod 13 are integrally connected. The sliding sleeve 6, the straight rod 14, the lower end of the bent rod 13, and the double-eared hydraulic cylinder 9 are all located in the cavity 2. The double-eared hydraulic cylinder 9 is existing technology; its specific structure will not be described in detail here. The manufacturer of the double-eared hydraulic cylinder 9 is Shanghai Jinxiang Hydraulic Equipment Co., Ltd., and its model number is HSGL01-40 / dE.

[0032] In this utility model, the displacement of the clamping block 3 of the clamping device is driven by the small connecting rod 8 and the large connecting rod 7. The large connecting rod 7 is driven by the hydraulic rod. The coordinated displacement of the large connecting rod 7 and the automatic clamping of the device are achieved by the sliding sleeve 6 connected to the large connecting rod 7. The sliding sleeve 6 is sleeved on the intermediate shaft 5 and moves up and down. The automatic displacement and clamping of the hydraulic push rod, the large connecting rod 7, etc. are achieved by its own weight.

[0033] Working principle:

[0034] The bridge housing is lifted, and two clamping devices of this invention are placed below the two ends of the bridge housing. The bridge housing is then hoisted until the square sections at both ends of the bridge housing are located at the top of the device base 1, that is, the square sections of the bridge housing are located between the two clamping blocks 3. In the initial state, the distance between the two clamping blocks 3 is the largest. When it is necessary to clamp and fix the ends of the bridge housing, the double-ear hydraulic cylinder 9 is activated. The double-ear hydraulic cylinder 9 pushes the lower end of the large connecting rod 7, and the lower end of the large connecting rod 7 moves away from the double-ear hydraulic cylinder 9, that is, the lower ends of the two large connecting rods 7 move in opposite directions. The upper end of the large connecting rod 7 moves towards the intermediate shaft 5, that is, the upper ends of the two large connecting rods 7 move towards each other. During the movement, the large connecting rod 7 drives the sliding sleeve 6 to move downward along the intermediate shaft 5 through the straight rod 14. The upper ends of the two large connecting rods 7 push the clamping blocks 3 towards the intermediate shaft 5 through the small connecting rod 8. The clamping blocks 3 move in the guide groove, thereby quickly clamping and fixing the square sections at the ends of the bridge housing.

[0035] When it is necessary to separate the clamping device from the axle housing, the double-ear hydraulic cylinder 9 is activated in reverse. The lower end of the connecting rod 7 moves towards each other, while the upper ends of the straight rod 14 and sliding sleeve 6 move away from each other. During this movement, the connecting rod 7 drives the sliding sleeve 6 to move upward along the intermediate shaft 5 via the straight rod 14. The two clamping blocks 3 move away from each other, thereby releasing the end of the axle housing. The cooperation of the straight rod 14, sliding sleeve 6, and intermediate shaft 5 provides guidance and stability for the movement of the connecting rod 7.
