Description

Technical Field

[0001] The utility model relates to the technical field of screw tightening structures, in particular to a telescopic structure for tightening. Background Art

[0002] In the assembly process of machinery, electrical appliances and other products, various screw tightening operations are often required. With the increase in labor costs and the acceleration of industrial intelligent manufacturing, a large number of manufacturing companies have begun to use automatic conveying and screw tightening equipment to meet the needs of modern mass production and mechanical automation. Solutions for automatic conveying and automatic tightening of various types of screws, nuts and other materials have also emerged. When tightening screws, tightening equipment is required;

[0003] When tightening the screws with the existing screw tightening equipment, the worker only needs to install the screws on the tightening seat and turn on the tightening equipment to tighten the screws. However, when tightening the screws, the worker needs to hold the tightening equipment and apply pressure to the screws, which causes great damage to the worker's arm muscles and the worker's labor intensity is high. Therefore, we propose a telescopic structure for tightening. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings existing in the prior art. When tightening the screws with the existing screw tightening equipment, the staff only needs to install the screws on the tightening seat and turn on the tightening equipment to tighten the screws.

[0007] As a preferred solution of the utility model, a through hole is provided at the bottom of the protective cover corresponding to the output end of the driving motor, so that the driving motor can easily drive the telescopic rod to rotate after being turned on.

[0008] The technical effect of adopting the above further solution is: through the design of the through hole, when the drive motor is turned on, the drive motor can more conveniently drive the telescopic rod to rotate.

[0009] As a preferred solution of the utility model, the spiral rod is matched with the spiral groove, so that the spiral rod can be freely raised and lowered by rotating inside the spiral groove.

[0010] The technical effect of adopting the above further solution is: by adapting the spiral rod to the spiral groove, when the drive motor drives the telescopic rod and the spiral rod to rotate together, the spiral rod can rotate inside the spiral groove, thereby allowing the spiral rod to rise or fall.

[0011] As a preferred solution of the utility model, the rotating column is rotatably connected to the rotating groove, and the first blocking block is matched with the second blocking block.

[0012] The technical effect of adopting the above further scheme is: through the rotatable connection between the rotating column and the rotating groove and the adaptation of the first blocking block and the second blocking block, when the rotating seat rotates clockwise, the first blocking block can be stuck by the second blocking block, so that the rotating seat can drive the screw rod to rotate together, and when the screw rod rotates counterclockwise, the first blocking block will not be affected by the second blocking block.

[0013] As a preferred solution of the utility model, a tightening seat is fixed at the bottom of the spiral rod and located inside the mounting seat, and a return spring is provided on the outer sleeve of the tightening seat.

[0014] The technical effect of adopting the above further solution is that the screw can be tightened by the tightening seat, and the reset spring can help the spiral rod to reset.

[0015] As a preferred solution of the utility model, a tightening groove is provided at the bottom of the tightening seat, and a telescopic hole is provided at the bottom of the mounting seat corresponding to the tightening seat, and the telescopic hole is adapted to the tightening seat.

[0016] The technical effect of adopting the above further solution is: the screw can be better fixed by the design of the tightening groove, and the tightening seat can be better freely lifted and lowered inside the tightening hole by matching the telescopic hole with the tightening seat.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] In the utility model, through the design of the telescopic rod, the rotating groove, the spiral rod, the spiral groove and the rotating groove, when tightening the screw, the driving motor will drive the telescopic rod and the rotating seat to rotate clockwise together, and the rotating seat can drive the spiral rod to rotate when rotating, and the spiral rod will descend inside the spiral groove when rotating clockwise, thereby driving the tightening seat to rotate and descend at the same time to tighten the screw, and after the screw is tightened, the return spring will also apply pressure to the spiral rod, so that the spiral rod can be rotated and ascended through the spiral groove to recycle the tightening seat, which makes it easier to tighten the screw and reduces the labor intensity of the staff.

[0030] Example 2

[0031] like Figure 1-4As shown, a through hole 102 is provided at the bottom of the protective cover 1 corresponding to the output end of the driving motor 101, so that the driving motor 101 can easily drive the telescopic rod 201 to rotate after being turned on. Through the design of the through hole 102, when the driving motor 101 is turned on, the driving motor 101 can more easily drive the telescopic rod 201 to rotate.

[0032] The spiral rod 301 is adapted to the spiral groove 302, so that the spiral rod 301 can be freely raised and lowered by rotating inside the spiral groove 302. The spiral rod 301 is adapted to the spiral groove 302, so that when the drive motor 101 drives the telescopic rod 201 and the spiral rod 301 to rotate together, the spiral rod 301 can rotate inside the spiral groove 302, so that the spiral rod 301 can rise or fall.

[0033] The rotating column 303 is rotatably connected to the rotating groove 203, and the first blocking block 304 is adapted to the second blocking block 204. By the rotating column 303 being rotatably connected to the rotating groove 203 and the first blocking block 304 being adapted to the second blocking block 204, when the rotating seat 202 rotates clockwise, the first blocking block 304 can be stuck by the second blocking block 204, so that the rotating seat 202 can drive the spiral rod 301 to rotate together, and when the spiral rod 301 rotates counterclockwise, the first blocking block 304 will not be affected by the second blocking block 204.

[0034] A tightening seat 305 is fixed at the bottom of the spiral rod 301 and inside the mounting seat 3. A reset spring 306 is provided on the outer sleeve of the tightening seat 305. The screw can be tightened through the tightening seat 305, and the reset spring 306 can help the spiral rod 301 to reset.

[0035] A tightening groove 307 is provided at the bottom of the tightening seat 305, and a telescopic hole 308 is provided at the bottom of the mounting seat 3 corresponding to the tightening seat 305. The telescopic hole 308 is adapted to the tightening seat 305. The design of the tightening groove 307 allows the screw to be better fixed, and the telescopic hole 308 is adapted to the tightening seat 305, so that the tightening seat 305 can be better freely raised and lowered inside the telescopic hole 308.

[0036] The working process of the utility model is as follows: when a tightening telescopic structure is used to tighten a screw, the worker can first turn on the driving motor 101, and the driving motor 101 will drive the telescopic rod 201 and the rotating seat 202 to rotate clockwise. When the rotating seat 202 rotates, the first blocking block 304 can be stuck by the second blocking block 204, so that the rotating seat 202 can drive the spiral rod 301 to rotate. When the spiral rod 301 rotates clockwise, it will drop inside the spiral groove 302, so that the tightening seat 305 can be driven to rotate and drop at the same time. The screw 301 is lowered to tighten the screw. After the screw is tightened, the staff can control the drive motor 101 to drive the telescopic rod 201 to rotate counterclockwise, and the return spring 306 will also apply pressure to the spiral rod 301, so that the spiral rod 301 can rotate and rise through the spiral groove 302. When the spiral rod 301 rotates, the first blocking block 304 will not be affected by the second blocking block 204, so that the tightening seat 305 can be recovered. Compared with the existing telescopic structure for tightening, it is easier to tighten the screw, which effectively reduces the labor intensity of the staff.
