Description

Technical Field

[0001] The present invention relates to the field of spring production equipment, and particularly relates to a clockwork spring production equipment. Background Art

[0002] A clockwork spring, also known as a volute spring, is a spring with one end fixed and a torque acting on the other end. Under the action of the torque, the spring material produces bending elastic deformation, causing the spring to twist in a plane, and the magnitude of the deformation angle is proportional to the torque. The traditional clockwork spring is formed by winding a spring steel strip in a straight state or a prefabricated steel coil from the previous process in the defined reverse direction into a clockwork spring with elasticity and fixing it in a steel ring, and finally assembling it into a corresponding housing for use. However, the existing equipment for winding the prefabricated steel coil in the reverse direction is large and has a relatively complex structure, resulting in low production efficiency. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a clockwork spring production equipment with a compact structure and high production efficiency.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0005] A clockwork spring production equipment includes a workbench, a feeding device, and a spring winding device; the feeding device includes a feeding roller vertically arranged on the workbench, the feeding roller is used for installing a prefabricated steel coil, a right-angle hook is provided at the end of the outermost circle of the prefabricated steel coil, and a folding hook is provided at the end of the innermost circle of the prefabricated steel coil; the spring winding device includes a rotatable turntable arranged on the workbench, an installation hole is provided at the center of the turntable, a rotating column is installed in the installation hole, a clamping groove for fixing the right-angle hook is provided on the rotating column, a motor is provided below the workbench, the motor drives the rotating column to rotate so that the prefabricated steel coil is wound from the feeding roller to the rotating column, a convex block is provided on the side of the turntable, a sensor for cooperating with the convex block is provided on the workbench, a fixed column is further provided on the turntable between the feeding device and the rotating column, when the rotating column drives the prefabricated steel coil to complete winding, the folding hook hooks the fixed column to drive the turntable to rotate so that the convex block cooperates with the sensor, the sensor controls the motor to stop, a reset spring for connecting with the turntable is further provided on the workbench, when the motor reversely rotates to release the steel coil, the production of the clockwork spring is completed, and the reset spring drives the turntable to reset.

[0006] A production device for a spiral spring according to an embodiment of the present invention has at least the following beneficial effects: During operation, first install the prefabricated steel coil on the loading roller, then pull out the right-angle hook at the outermost end of the loading roller and fix it in the card slot of the rotating column. After the fixing is completed, the motor can be started. The motor drives the rotating column to rotate, so that the prefabricated steel coil is wound from the loading roller to the rotating column. When the rotating column drives the prefabricated steel coil to complete winding, the folding hook hooks the fixed column, thereby driving the turntable to rotate so that the convex block cooperates with the sensor, and the sensor controls the motor to stop. It should be noted that when the motor stops, the rotating column no longer rotates. At this time, put the steel ring on the outer ring of the steel belt wound around the rotating column, and then the motor reverses several turns. The steel belt bounces outwards under the action of elastic force and is fixed together with the steel ring. At this time, the folding hook is released from the fixed column, and the return spring drives the turntable to reset under the action of elastic force. Finally, take out the spiral spring, thus completing the production of the spiral spring. Therefore, the production device for this spiral spring has a compact structure and high production efficiency.

[0007] According to some embodiments of the present invention, it further includes a partition device. The partition device includes a lifting plate, a first cylinder for driving the lifting plate, and a column for installing the first cylinder. The lifting plate is used to cover the upper part of the rotating column, and the column is installed on the workbench.

[0008] Beneficially, by setting the lifting plate, when the prefabricated steel belt is wound from the loading roller to the rotating column and the motor reverses and releases, it can cover the upper part of the rotating column to prevent the steel coil from popping up upwards from the rotating column due to elastic force.

[0009] According to some embodiments of the present invention, the lifting plate is circular.

[0010] Beneficially, the lifting plate is set to be circular and matches the shape of the spiral spring, which can help save space and effectively cover the upper part of the rotating column.

[0011] According to some embodiments of the present invention, it further includes a guiding device located between the loading device and the spring coiling device. The guiding device includes a fixed seat arranged on the workbench, a cantilever installed on the fixed seat, and a guide wheel installed on the cantilever. The guide wheel is used to abut against the steel belt coming out of the prefabricated steel coil so that the steel belt can be wound around the rotating column closely against the fixed column.

[0012] Beneficially, the guiding device abuts against the steel belt through the guide wheel, so that the steel belt can be wound around the rotating column closely against the fixed column. On the one hand, it can provide tension for the steel belt, and on the other hand, it ensures that when the winding is completed, the folding hook hooks the fixed column, thereby driving the turntable to rotate so that the convex block cooperates with the sensor.

[0013] According to some embodiments of the present invention, a plurality of limiting columns for restricting the prefabricated steel coil from popping outwards are provided on the circumference of the turntable.

[0014] Advantageously, the provision of the limit posts can prevent the clockwork spring from popping outwards from the rotating column when the motor rotates in the reverse direction to loosen the steel coil.

[0015] According to some embodiments of the present invention, multiple said limit posts are arranged uniformly in a circle.

[0016] Advantageously, such an arrangement matches the shape of the clockwork spring, which is beneficial for each limit post to play its role.

[0017] According to some embodiments of the present invention, a second cylinder is provided under the workbench, the motor is installed on the second cylinder, and the second cylinder can drive the motor to lift so as to drive the rotating column to lift.

[0018] Advantageously, by providing the second cylinder to drive the motor to lift, and thus drive the rotating column to lift, when the clockwork spring production is completed, the rotating column can descend and separate from the clockwork spring, which is beneficial for workers to take out the clockwork spring.

[0019] According to some embodiments of the present invention, a bearing is provided under the turntable, the turntable is connected to the workbench through the bearing, the bearing is provided with a through hole, and the motor is connected to the rotating column through the through hole.

[0020] Advantageously, such an arrangement of the bearing can well install the turntable to make the turntable rotatable. In addition, it is also beneficial for the connection and installation of the motor and the rotating column.

[0021] According to some embodiments of the present invention, the feeding device further includes a support seat, the top surface of the support seat is at the same height as the top surface of the turntable, and the feeding roller is vertically installed on the support seat.

[0022] Advantageously, such an arrangement can ensure that the prefabricated steel coil of the feeding roller is smoothly wound onto the rotating column.

[0023] According to some embodiments of the present invention, a first connection block is provided below the turntable, a second connection block is provided on the workbench, and the return spring connects the first connection block and the second connection block.

[0024] Advantageously, such an arrangement for installing the return spring has a simple structure and at the same time plays a good resetting role.

[0036] The following refers to Figures 1 - 4 A clockwork spring production device will be described in detail with a specific embodiment. It should be understood that the following description is only an exemplary illustration and not a specific limitation of the invention.

[0037] As Figure 1 Figure 2 As shown, a clockwork spring production device includes a workbench 100, a feeding device, and a spring coiling device.

[0038] Among them, the feeding device includes a feeding roller 110 erected on the workbench 100. The feeding roller 110 is used to install a prefabricated steel coil 120. A right-angle hook 130 is provided at the end of the outermost circle of the prefabricated steel coil 120, and a folding hook 140 is provided at the end of the innermost circle of the prefabricated steel coil 120. The spring coiling device includes a rotatable turntable 150 provided on the workbench 100. An installation hole 160 is provided at the center of the turntable 150. A rotating column 170 is installed in the installation hole 160. A clamping groove 180 for fixing the right-angle hook 130 is provided on the rotating column 170. A motor 190 is provided below the workbench 100. The motor 190 drives the rotating column 170 to rotate, so that the prefabricated steel coil 120 is wound from the feeding roller 110 onto the rotating column 170. A convex block 200 is provided on the side of the turntable 150, and a sensor 210 for cooperating with the convex block 200 is provided on the workbench 100. A fixed column 220 is also provided on the turntable 150 between the feeding device and the rotating column 170. When the rotating column 170 drives the prefabricated steel coil 120 to complete winding, the folding hook 140 hooks the fixed column 220, thereby driving the turntable 150 to rotate so that the convex block 200 cooperates with the sensor 210, and the sensor 210 controls the motor 190 to stop. A return spring 230 for connecting with the turntable 150 is also provided on the workbench 100. When the motor 190 reverses to release the steel coil, the production of the clockwork spring is completed, and the return spring 230 drives the turntable 150 to reset.

[0039] During operation, as Figure 2 shown, first install the prefabricated steel coil 120 on the feeding roller 110, and then pull out the right-angle hook 130 at the end of the outermost circle of the feeding roller 110 and fix it in the clamping groove 180 of the rotating column 170. After the fixing is completed, the motor 190 can be started. The motor 190 drives the rotating column 170 to rotate, so that the prefabricated steel coil 120 is wound from the feeding roller 110 onto the rotating column 170. As Figure 3As shown, when the winding column 170 drives the prefabricated steel coil 120 to complete winding, the folding hook 140 hooks the fixed column 220 to drive the turntable 150 to rotate so that the convex block 200 cooperates with the sensor 210, and the sensor 210 controls the motor 190 to stop. It should be noted that when the motor 190 stops, the winding column 170 no longer rotates. At this time, the steel ring 370 is sleeved on the outer ring of the steel strip wound around the winding column 170, and then the motor 190 reverses several turns. Under the action of elastic force, the steel strip bounces outwards and is fixed together with the steel ring 370, as Figure 4 shown. At this time, the folding hook 140 is loosened from the fixed column 220, and the return spring 230 drives the turntable 150 to reset under the action of elastic force. Finally, the clockwork spring is taken out, thus completing the production of the clockwork spring. Therefore, the structure of this clockwork spring production equipment is compact and the production efficiency is high.

[0040] As Figure 1 shown, it further includes a partition device. The partition device includes a lifting plate 240, a first cylinder 250 for driving the lifting plate 240, and a column 260 for installing the first cylinder 250. The lifting plate 240 is used to cover the upper part of the winding column 170, and the column 260 is installed on the workbench 100. By setting the lifting plate 240, when the prefabricated steel strip is wound from the feeding roller 110 to the winding column 170 and when the motor 190 reverses and loosens, the upper part of the winding column 170 can be covered to prevent the steel coil from popping up upwards from the winding column 170 due to elastic force.

[0041] Specifically, the lifting plate 240 is circular. The lifting plate 240 is set to be circular to match the shape of the clockwork spring, which can help save space and effectively cover the upper part of the winding column 170.

[0042] Moreover, it further includes a guiding device located between the feeding device and the spring winding device. The guiding device includes a fixed seat 270 arranged on the workbench 100, a cantilever 280 installed on the fixed seat 270, and a guide wheel 290 installed on the cantilever 280. The guide wheel 290 is used to abut against the steel strip coming out of the prefabricated steel coil 120 so that the steel strip can be wound around the fixed column 220 and then onto the winding column 170 closely. The guiding device abuts against the steel strip through the guide wheel 290, so that the steel strip can be wound around the fixed column 220 and then onto the winding column 170 closely. On the one hand, it can provide tension for the steel strip, and on the other hand, it ensures that when the winding is completed, the folding hook 140 hooks the fixed column 220 to drive the turntable 150 to rotate so that the convex block 200 cooperates with the sensor 210.

[0043] In addition, a plurality of limiting columns 300 for restricting the prefabricated steel coil 120 from popping outwards are arranged on the circumference of the turntable 150. The arrangement of the limiting columns 300 can prevent the clockwork spring from popping outwards from the winding column 170 when the motor 190 reverses and loosens the steel coil.

[0044] Furthermore, multiple limiting posts 300 are arranged evenly in a circle. This setting matches the shape of the clockwork spring, which is beneficial for each limiting post 300 to play its role.

[0045] In some specific embodiments of the present invention, as Figure 1 shown, a second cylinder 310 is provided under the workbench 100, and the motor 190 is installed on the second cylinder 310. The second cylinder 310 can drive the motor 190 to lift and thus drive the rotating column 170 to lift. By setting the second cylinder 310 to drive the motor 190 to lift and thus drive the rotating column 170 to lift, when the clockwork spring production is completed, the rotating column 170 can descend and separate from the clockwork spring, which is beneficial for workers to take out the clockwork spring.

[0046] It should be noted that a bearing 320 is provided under the turntable 150. The turntable 150 is connected to the workbench 100 through the bearing 320. The bearing 320 is provided with a through hole 330, and the motor 190 is connected to the rotating column 170 through the through hole 330. Such a setting of the bearing 320 can well install the turntable 150, make the turntable 150 rotatable, and is also beneficial for the connection and installation of the motor 190 and the rotating column 170.

[0047] It can be understood that the feeding device further includes a support seat 340. The top surface of the support seat 340 is at the same height as the top surface of the turntable 150, and the feeding roller 110 is vertically installed on the support seat 340. Such a setting can ensure that the prefabricated steel coil 120 of the feeding roller 110 is smoothly wound onto the rotating column 170.

[0048] It is worth mentioning that, as Figure 1 and Figure 2 shown, a first connection block 350 is provided under the turntable 150, and a second connection block 360 is provided on the workbench 100. The return spring 230 connects the first connection block 350 and the second connection block 360. Such a setting for installing the return spring 230 has a simple structure and at the same time plays a good resetting role.

[0049] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to the above embodiments. Within the knowledge scope of those of ordinary skill in the art in the said technical field, various changes can be made without departing from the purpose of the present invention.
