Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, specifically to a screw grooving processing fixture. Background Technology

[0002] Screw grooving fixtures are indispensable key equipment in screw manufacturing. They are mainly used to machine grooves of specific shapes into the screw head to meet the tightening and loosening requirements of different applications. Through precise clamping and positioning, the fixture ensures the screw remains stable during the grooving process, thereby guaranteeing the accuracy and quality of the grooving. These fixtures are widely used in construction, machinery manufacturing, automotive, electronics, and aerospace industries, playing a crucial role in improving screw production efficiency and product quality.

[0003] Chinese patent document CN 222243740U discloses a screw grooving fixture, including a support frame, an angle adjusting cylinder vertically upward mounted on the support frame, and a support plate fixed to the piston rod of the angle adjusting cylinder. However, the above technical solution still has the following drawbacks: After the screw grooving is completed, the existing technology requires manual unloading of each screw individually, which is time-consuming and labor-intensive. After unloading, it is necessary to wait for each screw to be loaded before starting the next batch of screws, resulting in a long processing interval and low efficiency.

[0004] Therefore, a screw grooving fixture is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a screw grooving fixture in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A screw grooving fixture includes a base, on the surface of which is provided an alternating moving mechanism. Two support platforms are provided above the alternating moving mechanism. A height adjustment component for adjusting the height of one of the support platforms is installed on the surface of the alternating moving mechanism. A screw clamping component is provided on the top surface of the support platform. An automatic unloading component for controlling the rotation of the screw clamping component is also provided on the top surface of the support platform.

[0008] Furthermore, the alternating movement mechanism includes a first threaded rod and a second threaded rod, both of which are rotatably connected to the inner wall of the base. The threads on the surfaces of the first and second threaded rods are in opposite directions. A first support frame is threadedly connected to the surface of the first threaded rod, and a second support frame is threadedly connected to the surface of the second threaded rod. A first sliding groove is formed through the top surface of the base, and the inner wall of the first sliding groove is slidably connected to the surface of the first support frame. Second sliding grooves are formed through the front and back surfaces of the base, and the inner walls of the second sliding grooves are slidably connected to the surface of the second support frame. The alternating movement mechanism also includes a drive assembly for controlling the synchronous rotation of the first and second threaded rods.

[0009] Furthermore, the drive assembly includes a motor, which is fixedly mounted on the inner wall of the base. The output end of the motor is fixedly connected to a rotating shaft, and the end of the rotating shaft is fixedly connected to a drive wheel. Driven wheels are fixedly sleeved on the surfaces of the first threaded rod and the second threaded rod, and belts mesh between the drive wheel and the two driven wheels.

[0010] Furthermore, the height adjustment assembly includes a first electric push rod, which is fixedly installed inside the second support frame. The telescopic end of the first electric push rod is fixedly connected to a connecting rod, which is fixedly connected to the support platform and movably inserted into the second support frame.

[0011] Furthermore, the screw clamping assembly includes a fixed clamping plate, a sliding column is fixedly connected to the left side of the fixed clamping plate, a movable clamping plate is slidably connected to the surface of the sliding column, grooves adapted to the screw are provided on the opposite sides of the fixed clamping plate and the movable clamping plate, and a second electric push rod is fixedly installed on the surface of the fixed clamping plate, the telescopic end of the second electric push rod is fixedly connected to the movable clamping plate.

[0012] Furthermore, the automatic feeding assembly includes a hinged seat and a bracket, both of which are fixedly connected to the top surface of the support platform. The top of the hinged seat is hinged to a fixed clamping plate, the top surface of the bracket is in contact with the bottom surface of the fixed clamping plate, a third electric push rod is hinged to the top surface of the support platform, and the telescopic end of the third electric push rod is hinged to the fixed clamping plate. The top surface of the support platform is inclined with the right side higher than the left side, and a storage box is fixedly connected to the left side of the top surface of the base.

[0013] The beneficial effects of this utility model are as follows:

[0014] The base is installed on the right side of the grooving equipment. The screw to be processed is placed on the screw clamping assembly on the right side, and the screw is clamped and fixed by the screw clamping assembly. Then, through the operation of the alternating moving mechanism, the two support platforms can be driven to move in opposite directions, so that the right support platform and the screw move to the left and approach the grooving equipment for grooving processing. The other unloaded support platform will move to the right side, and the screw can be loaded. After the screw grooving is completed, the screw clamping assembly is released from its limit. Then, the automatic unloading assembly is operated, controlling the screw clamping assembly to rotate to the left, so that the screw slides down under the action of gravity, and the screw is automatically unloaded. In use, this utility model realizes the effect of automatic unloading of grooved screws, making the processing easier and less labor-intensive. Moreover, the next batch of screws can be loaded while the previous batch of screws is being processed, thus effectively reducing the processing interval and improving the screw processing efficiency.

[0027] like Figures 1 to 6As shown, a screw grooving fixture includes a base 1. An alternating movement mechanism 2 is provided on the surface of the base 1. The alternating movement mechanism 2 includes a first threaded rod 204 and a second threaded rod 205, both of which are rotatably connected to the inner wall of the base 1. The threads on the surfaces of the first threaded rod 204 and the second threaded rod 205 have opposite directions. A first support frame 208 is threadedly connected to the surface of the first threaded rod 204, and a second support frame 209 is threadedly connected to the surface of the second threaded rod 205. A first sliding groove 206 is provided through the top surface of the base 1, and the inner wall of the first sliding groove 206 is slidably connected to the surface of the first support frame 208. Second sliding grooves 207 are provided through the front and back surfaces of the base 1, and the inner wall of the second sliding groove 207 is slidably connected to the surface of the second support frame 209. The alternating movement mechanism 2 also includes a drive assembly for controlling the synchronous rotation of the first threaded rod 204 and the second threaded rod 205. It should be noted that by controlling the rotation of the first threaded rod 204 and the second threaded rod 205 through the drive component, the first support frame 208 will slide along the inner wall of the first slide groove 206 and the second support frame 209 will slide along the inner wall of the second slide groove 207 under the action of the thread, thereby driving the two support platforms 4 to move in opposite directions and realizing the alternating switching of the positions of the two support platforms 4.

[0028] The drive assembly includes a motor 201, which is fixedly mounted on the inner wall of the base 1. A rotating shaft 202 is fixedly connected to the output end of the motor 201, and a drive wheel 203 is fixedly connected to the end of the rotating shaft 202. Driven wheels are fixedly sleeved on the surfaces of the first threaded rod 204 and the second threaded rod 205. Belts mesh between the drive wheel 203 and both driven wheels. More specifically, the operation of the motor 201 drives the rotating shaft 202 to rotate, which in turn drives the drive wheel 203 to rotate. Under the transmission of the belts, the driven wheels rotate, thereby controlling the synchronous rotation of the first threaded rod 204 and the second threaded rod 205.

[0029] Two support platforms 4 are provided above the alternating movement mechanism 2. A height adjustment component 3 for adjusting the height of one of the support platforms 4 is installed on the surface of the alternating movement mechanism 2. The height adjustment component 3 includes a first electric push rod 301, which is fixedly installed inside the second support frame 209. A connecting rod 302 is fixedly connected to the telescopic end of the first electric push rod 301, and the connecting rod 302 is fixedly connected to the support platform 4 and movably inserted into the second support frame 209. It should be noted that by operating the first electric push rod 301, the connecting rod 302 is driven to move upward, which in turn drives the support platform 4 to move upward, making one support platform 4 higher than the other, thereby avoiding interference when the two support platforms 4 are close to each other.

[0030] The top surface of the support platform 4 is provided with a screw clamping assembly 5, which includes a fixed clamping plate 501. A sliding column 502 is fixedly connected to the left side of the fixed clamping plate 501, and a movable clamping plate 503 is slidably connected to the surface of the sliding column 502. Grooves adapted to screws are provided on the opposite sides of both the fixed clamping plate 501 and the movable clamping plate 503. A second electric push rod 504 is fixedly mounted on the surface of the fixed clamping plate 501, and the telescopic end of the second electric push rod 504 is fixedly connected to the movable clamping plate 503. More specifically, the screw is first placed in the groove on the surface of the fixed clamping plate 501, and then the second electric push rod 504 is operated to pull the movable clamping plate 503 to slide along the surface of the sliding column 502, thereby clamping and fixing the screw.

[0031] The top surface of the support platform 4 is also equipped with an automatic unloading assembly 6 for controlling the rotation of the screw clamping assembly 5. The automatic unloading assembly 6 includes a hinge seat 601 and a bracket 602, and both the hinge seat 601 and the bracket 602 are fixedly connected to the top surface of the support platform 4. The top end of the hinge seat 601 is hinged to the fixed clamping plate 501, and the top surface of the bracket 602 is in contact with the bottom surface of the fixed clamping plate 501. A third electric push rod 603 is hinged to the top surface of the support platform 4, and the telescopic end of the third electric push rod 603 is hinged to the fixed clamping plate 501. The top surface of the support platform 4 is inclined with the right side higher than the left side. A storage box 604 is fixedly connected to the left side of the top surface of the base 1. It should be noted that when the screw clamping assembly 5 releases its grip on the screw, the third electric push rod 603 drives its telescopic end to extend, thereby pushing the fixed clamping plate 501 to rotate around the top of the hinge seat 601. The screw on the surface of the screw clamping assembly 5 will fall to the top of the support platform 4. Under the action of the inclined surface, it can slide to the left and fall into the storage box 604 for storage, realizing automatic unloading.

[0032] In summary: The base 1 is installed on the right side of the grooving equipment. The screw to be processed is placed on the screw clamping assembly 5 on the right side, and the screw is clamped and fixed by the screw clamping assembly 5. Then, by operating the alternating moving mechanism 2, the two support platforms 4 can be driven to move in opposite directions, so that the right support platform 4 and the screw move to the left and approach the grooving equipment for grooving processing. The other unloaded support platform 4 will reach the right side, and the screw can be loaded. After the screw grooving is completed, the screw is released by the screw clamping assembly 5. Then, by operating the automatic unloading assembly 6, the screw clamping assembly 5 is rotated to the left, so that the screw slides down under the action of gravity, and the screw is automatically unloaded. In use, this utility model realizes the effect of automatically unloading the grooved screws, making the processing easier and less labor-intensive. Moreover, the next batch of screws can be loaded while the previous batch of screws is being processed, thus effectively reducing the processing interval and improving the screw processing efficiency.
