Description

Technical Field

[0001] This utility model relates to the technical field of bolt thread rolling, and in particular to the technical field of a bolt thread rolling device. Background Technology

[0002] Thread rolling machines are specialized equipment for producing bolts. There are various specifications of thread rolling machines, such as automatic thread rolling machines, flat thread rolling machines, semi-automatic thread rolling machines, fully automatic thread rolling machines, and high-speed thread rolling machines. Thread rolling machines are lightweight, flexible, efficient, and have advantages that other similar equipment cannot replace. Thread rolling machines avoid the limitations of lathes, drilling machines, or manual tapping, saving time and effort, reducing the risk of thread damage, and preventing tap breakage.

[0003] In the existing technology, when feeding a typical thread rolling machine, it is possible to feed more than one blank, which greatly affects the thread rolling effect. In addition, a typical thread rolling machine only has one thread rolling structure, which relies on the drive structure to drive the thread rolling plate to roll the thread, resulting in limited efficiency.

[0004] To address the problems mentioned above, for example, application number CN202022290141.5 discloses a thread rolling machine for bolt processing, including a base. The top of the base is provided with a feeding structure, a thread rolling structure, and two collection boxes from top to bottom. Both the feeding structure and the thread rolling structure are inclined from top to bottom. The height of the feeding structure is higher than that of the thread rolling structure and corresponds to the thread rolling structure. The bottom of the feeding structure is provided with a drive structure. The thread rolling structure includes a feeding groove, a distribution plate, and a reciprocating screw. The thread rolling structure includes two fixed grooves, two moving thread rolling plates, and a stationary thread rolling plate. Relying on the inverted T-shaped feeding groove and the distribution plate, the blanks are sorted, which not only ensures that only one blank enters the thread rolling structure at a time, improving the thread rolling effect, but also allows the blanks to be sent into different thread rolling pipes, providing convenience for subsequent thread rolling.

[0005] While the above-mentioned device achieves a simple structure and convenient use, it does not solve the problem of the cumbersome replacement of the thread rolling plates in existing thread rolling machines.

[0006] To address the problems mentioned above, for example, application number CN202020153017.1 discloses a thread rolling machine for bolt processing, including a support base, a fixing assembly, the bottom of which is fixedly connected to the top of the support base, and two support plates. The bottoms of the two support plates are fixedly connected to the front and rear sides of the top of the support base. The two support plates are located on the front and rear sides of the fixing assembly. By using the fixing assembly, the fixed thread rolling plate can be replaced more conveniently and can be better fixed, improving the ease of use and practicality of the device. The cooperation of the clamping block and the limiting block can fix the fixed thread rolling plate on the device, ensuring that the fixed thread rolling plate will not move during use, thus improving the stability of the device during use.

[0007] However, the above-mentioned device still has the following drawbacks:

[0008] As the bolts are rolled by the moving and stationary thread rolling plates, threads are formed. However, iron filings are also easily shed from the bolts. After the first batch of bolts is rolled, a lot of iron filings tend to stick to the moving and stationary thread rolling plates. If the filings cannot be cleaned in time, they will easily be pressed onto the bolts in the second batch of bolts. This will easily cause more burrs to be generated on the bolts after the second batch of bolts is rolled, which will affect the subsequent use of the bolts and affect the thread rolling effect. Summary of the Invention

[0009] The purpose of this invention is to solve the problems in the prior art and to propose a bolt thread rolling device that can clean the thread rolling surfaces of the moving thread rolling plate and the stationary thread rolling plate in a timely manner, so as to avoid the subsequent bolt processing due to debris adhering to the moving thread rolling plate and the stationary thread rolling plate.

[0010] To achieve the above objectives, this utility model proposes a bolt thread rolling device, including a concave support, a movable thread rolling plate, a stationary thread rolling plate, a drive mechanism, a cleaning mechanism, a concave bracket, a reciprocating screw, a moving block, an electric telescopic rod, a fixed seat, a cleaning roller, a brush, and a chip collection groove. The movable and stationary thread rolling plates are located above the concave support. A drive mechanism is connected to one side of the movable thread rolling plate. A cleaning mechanism is located on the concave support. The cleaning mechanism includes the concave bracket, the reciprocating screw, the moving block, the electric telescopic rod, the fixed seat, the cleaning roller, and the brush. The reciprocating screw is rotated between the concave brackets. A moving block is threaded onto the outer wall of the reciprocating screw. An electric telescopic rod is connected to the lower end of the moving block. A fixed seat is connected to the telescopic end of the electric telescopic rod. The fixed seat has open structures on both sides, and a cleaning roller is rotated on the inner side of each fixed seat. A brush is adhered to the outer wall of each cleaning roller. A chip collection groove is located directly below the movable and stationary thread rolling plates.

[0011] Preferably, the driving mechanism includes a fixed base, a turntable, a connecting rod, and a first motor. The turntable is rotatably mounted on the side wall of the fixed base, and a connecting rod is connected to the turntable. The other end of the connecting rod is connected to the side wall of the moving thread rolling plate. The first motor is mounted on the fixed base, and the output shaft of the first motor passes through the side wall of the fixed base and is connected to the turntable.

[0012] Preferably, the concave bracket has a second motor on its side wall, and the output shaft of the second motor passes through the side wall of the concave bracket and is connected to a reciprocating lead screw.

[0013] Preferably, a third motor is provided on the side wall of the fixed base, and the output shaft of the third motor passes through the side wall of the fixed base and is connected to the cleaning roller.

[0014] Preferably, the outer diameter of the fixed base is adapted to the gap between the moving thread rolling plate and the stationary thread rolling plate, and the brush is in close contact with the thread rolling surfaces of the moving thread rolling plate and the stationary thread rolling plate respectively.

[0015] Preferably, the chip collection groove is provided with chip guide plates on both sides below, and a chip collection box is installed below the concave support, with the chip guide plates tilting towards the chip collection box.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model, by setting a cleaning mechanism, can clean the thread-rolling surfaces of the moving and stationary thread-rolling plates. After the first batch of bolts is threaded, the drive mechanism is turned off, causing the moving thread-rolling plate to stop moving. Then, the electric telescopic rod is activated to descend, thereby driving the cleaning rollers on both sides of the fixed base to descend until the brush comes into contact with the thread-rolling surfaces of the moving and stationary thread-rolling plates. Then, the third motor is activated, and the output shaft of the third motor drives the cleaning rollers to rotate, so that the brush can clean the debris attached to the moving and stationary thread-rolling plates. At the same time, the second motor is activated, and the output shaft of the second motor drives the reciprocating screw to rotate. The forward and reverse rotation of the reciprocating screw drives the moving block to move back and forth, so that the brush can clean the thread-rolling surfaces of the moving and stationary thread-rolling plates during the movement, thereby ensuring a uniform cleaning effect and avoiding the problem of debris adhering to the moving and stationary thread-rolling plates affecting subsequent bolt processing. This solves the problem of debris adhering to the thread-rolling plates affecting subsequent bolt processing.

[0018] 2. This utility model, through the combined action of the chip collection trough, chip guide plate, and chip collection box, can collect the debris after sweeping. When the brush sweeps the debris down during rotation, the debris falls into the chip collection trough and slides down to the chip collection box through the chip guide plate, thus completing the collection.

Detailed Implementation

[0024] See Figures 1 to 4 This utility model discloses a bolt thread rolling device, comprising a concave support 1, a movable thread rolling plate 2, a stationary thread rolling plate 3, a drive mechanism 4, a cleaning mechanism 5, a concave bracket 501, a reciprocating screw 502, a moving block 503, an electric telescopic rod 504, a fixed seat 505, a cleaning roller 506, a brush 507, and a chip collection groove 6. The movable thread rolling plate 2 and the stationary thread rolling plate 3 are located above the concave support 1. The drive mechanism 4 is connected to one side of the movable thread rolling plate 2. The cleaning mechanism 5 is located on the concave support 1. The cleaning mechanism 5 includes the concave bracket 501, the reciprocating screw 502, the moving block 503, the electric telescopic rod 504, the fixed seat 505, the cleaning roller 506, and the brush 507. The reciprocating screw 502 is rotatably mounted between the concave brackets 501. The moving block 503 is threadedly connected to the outer wall of the reciprocating screw 502. An electric telescopic rod 504 is connected to the lower end of block 503. The telescopic end of the electric telescopic rod 504 is connected to a fixed base 505. The fixed base 505 has an open structure on both sides and a cleaning roller 506 is mounted on the inner side of each fixed base 505. A brush 507 is attached to the outer wall of each cleaning roller 506. A chip collection groove 6 is provided directly below the moving shaving plate 2 and the stationary shaving plate 3. The cleaning roller 506 is rotated by the output shaft driven by the third motor 5055, so that the brush 507 can clean the debris attached to the moving shaving plate 2 and the stationary shaving plate 3. At the same time, the second motor 5011 drives the output shaft to rotate, which in turn drives the reciprocating screw 502 to rotate. The forward and reverse rotation of the reciprocating screw 502 drives the moving block 503 to move back and forth, so that the brush 507 can clean the shaving surfaces of the moving shaving plate 2 and the stationary shaving plate 3 during the movement.

[0025] See Figure 1 The driving mechanism 4 includes a fixed base 401, a turntable 402, a connecting rod 403, and a first motor 404. The turntable 402 is rotatably mounted on the side wall of the fixed base 401, and the connecting rod 403 is connected to the turntable 402. The other end of the connecting rod 403 is connected to the side wall of the movable thread rolling plate 2. The first motor 404 is mounted on the fixed base 401. The output shaft of the first motor 404 passes through the side wall of the fixed base 401 and is connected to the turntable 402. The first motor 404 drives the output shaft to rotate, thereby driving the turntable 402 to rotate, so that the connecting rod 403 drives the movable thread rolling plate 2 to move back and forth. At the same time, the slider (not shown in the figure) below the movable thread rolling plate 2 slides back and forth on the slide rail (not shown in the figure), thereby rolling the threads of the bolt.

[0026] See Figure 1 The concave bracket 501 is provided with a second motor 5011 on its side wall. The output shaft of the second motor 5011 passes through the side wall of the concave bracket 501 and is connected to the reciprocating screw 502. The output shaft is driven to rotate forward and backward by the second motor 5011, which in turn drives the reciprocating screw 502 to rotate forward and backward, so that the moving block 503 can reciprocate.

[0027] See Figure 3 and Figure 4 The side wall of the fixed base 505 is provided with a third motor 5055. The output shaft of the third motor 5055 passes through the side wall of the fixed base 505 and is connected to the cleaning roller 506. The cleaning roller 506 is driven to rotate by the third motor 5055, which in turn drives the brush 507 to rotate, so that the brush 507 can clean the shaving surface of the shaving plate.

[0028] See Figure 1 The outer diameter of the fixed seat 505 is adapted to the gap between the moving thread rolling plate 2 and the stationary thread rolling plate 3, and the brush 507 is in close contact with the thread rolling surfaces of the moving thread rolling plate 2 and the stationary thread rolling plate 3 respectively, so that the fixed seat 505 can fall into the gap between the moving thread rolling plate 2 and the stationary thread rolling plate 3 without getting stuck. In addition, an arc-shaped baffle (not shown in the figure) is installed on the upper side of the fixed seat 505 to prevent the debris from splashing outward and to allow the debris to fall downward.

[0029] See Figure 2 The chip collection trough 6 is provided with chip guide plates 601 on both sides below it, and a chip collection box 7 is installed below the concave support 1. The inclined direction of the chip guide plates 601 points to the chip collection box 7. When the brush 507 sweeps away the debris during rotation, the debris falls into the chip collection trough 6 and slides down to the chip collection box 7 through the chip guide plates 601, thus completing the collection.

[0030] The working process of this utility model:

[0031] In the operation of this bolt thread rolling device, after the first batch of bolts has been rolled, the drive mechanism 4 is closed, causing the moving thread rolling plate 2 to stop moving. Then, the electric telescopic rod 504 is activated to descend, thereby driving the cleaning rollers 506 on both sides of the fixed base 505 to descend until the brush 507 comes into contact with the rolling surfaces of the moving thread rolling plate 2 and the stationary thread rolling plate 3. Subsequently, the third motor 5055 is activated, and the output shaft of the third motor 5055 drives the cleaning rollers 506 to rotate, so that the brush 507 can remove the debris adhering to the moving thread rolling plate 2 and the stationary thread rolling plate 3. During the cleaning process, the second motor 5011 is started. The second motor 5011 drives the output shaft to rotate, which in turn drives the reciprocating screw 502 to rotate. The forward and reverse rotation of the reciprocating screw 502 drives the moving block 503 to reciprocate, so that the brush 507 can clean the rubbing surfaces of the moving rubbing plate 2 and the stationary rubbing plate 3 during the movement, thereby ensuring a uniform cleaning effect. When the brush 507 sweeps away the debris during the rotation, the debris falls into the debris collection trough 6 and slides down to the debris collection box 7 through the debris guide plate 601, thus completing the collection.

[0032] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0033] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
