Description

Technical Field

[0001] The present application relates to the technical field of shock absorber production equipment, and in particular to a shock absorber spring feeding auxiliary device. Background Art

[0002] Shock absorbers are devices used to suppress vibrations and play an important role in the vehicle suspension system. The main function of shock absorbers is to quickly attenuate vehicle body vibrations and improve the ride quality and comfort of the vehicle. During vehicle driving, shock absorbers help control the contact between the wheels and the ground, reduce the impact caused by uneven road surfaces, and maintain good contact between the tires and the ground, thereby enhancing the vehicle's handling stability.

[0003] Springs are important components of shock absorbers. Their main function is to absorb the repeated bounces caused by various impacts brought by the road surface, so as to accelerate the attenuation function of the inherent vibration of the springs and provide vehicles with better driving smoothness. Before the springs are assembled to the shock absorbers, they are randomly and disorderly stacked at the loading position. A robotic arm is required to take a spring and put it on the shock absorber body. When the robotic arm grabs the springs from the spring pile, it may grab multiple springs at the same time. In order to reduce the probability of errors when the robotic arm grabs the springs, it is necessary to manually sort out the randomly stacked springs and send them to the spring loading position one by one. It takes a long time to manually sort out the springs and send them to the loading position, which slows down the production rate of the shock absorber. Utility Model Content

[0004] The purpose of the present application is to provide a shock absorber spring feeding auxiliary device to address the above-mentioned problems, which can speed up the production rate of the spring and improve the above-mentioned problems.

[0005] This application is achieved through the following technical solutions:

[0006] In some embodiments, the present application provides a shock absorber spring loading auxiliary device, which includes a positioning assembly including a first turntable, a second turntable and a support shaft, the first turntable and the second turntable are connected by the support shaft, and the axial direction of the support shaft is a first direction; multiple positioning shafts, the positioning shafts are arranged on the first turntable around the axis of the first turntable, the positioning shafts are located between the first turntable and the second turntable, and the positioning shafts extend along the first direction, the first turntable is used to support the spring, and the positioning shafts are used to insert the spring; wherein, the second turntable is provided with multiple positioning holes, the multiple positioning holes correspond one-to-one to the multiple positioning shafts, and the positioning holes are used for the springs to pass through.

[0007] In the technical solution of the embodiment of the present application, the shock absorber spring feeding auxiliary device includes a positioning assembly including a first turntable, a second turntable and a supporting shaft. The first turntable and the second turntable are connected by the supporting shaft, so that there is a certain gap between the first turntable and the second turntable; the positioning shaft is arranged on the first turntable around the axis of the first turntable, and the positioning shaft extends along the first direction to guide the spring inserted in the positioning shaft to be vertical along the first direction. The first turntable is used to support the spring, and the positioning shaft is used to insert the spring; wherein, the second turntable is provided with a plurality of positioning holes, and the plurality of positioning holes correspond one-to-one to the plurality of positioning shafts. The positioning holes are used for the spring to pass through, and a part of the spring inserted in the positioning shaft passes through the positioning holes. The positioning holes limit the position of the head of the spring to avoid the entanglement of the plurality of springs placed on the positioning assembly. The springs are wound or staggered with each other so that the loading equipment (mechanical arm) will only grab one spring at a time, and the positioning axis limits the position of the bottom of the spring and guides the spring to remain vertical; in actual use of the shock absorber spring loading auxiliary device provided by the present application, the springs that fill all the positioning holes or positioning axes of a shock absorber spring loading auxiliary device are considered a batch. After the worker fills a shock absorber spring loading auxiliary device with springs, the shock absorber spring loading auxiliary device with a batch of springs is sent to the loading position. After the springs are taken out, a new shock absorber spring loading auxiliary device with a batch of springs is immediately replaced, and the springs are sent to the loading position in batches, avoiding the impact of the slow speed of manual spring sorting on the spring loading speed, so that the spring loading process remains uniform and fast.

[0008] In some embodiments, in the first direction, the dimension of the positioning axis is h, satisfying 12 cm ≤ h ≤ 18 cm.

[0009] In the technical solution of the embodiment of the present application, in the first direction, the size of the positioning axis is h. When 12cm≤h≤18cm is satisfied, the size of the portion of the spring that is restricted from bending by the positioning axis is longer, which better maintains the spring in a vertical state. At the same time, after the spring is grabbed by the feeding equipment, it only needs to move a shorter distance along the first direction to allow the spring to escape from the limit of the positioning axis, thereby reducing the risk of the spring bending due to the lateral movement of the spring when the spring is grabbed because the distance moved along the first direction is not enough to allow the spring to escape from the positioning axis.

[0010] In some embodiments, a frame is further included, the frame is provided with running wheels, and the positioning assembly is rotatably arranged on the frame.

[0011] In the technical solution of the embodiment of the present application, the frame is provided with running wheels, and the positioning assembly on which the springs are placed is moved on the ground or the work platform by the running wheels, thereby reducing the difficulty of transporting batches of springs. The positioning assembly is rotatably arranged on the frame, and the positioning assembly can be rotated to deliver the next grasped spring to the grasping position of the loading equipment (mechanical arm, etc.), thereby reducing the path that the loading equipment needs to move to grasp the spring, thereby reducing the time required for spring loading and accelerating the production rate of the shock absorber.

[0012] In some embodiments, the frame is further provided with a first driving member, the first driving member is placed on the frame, the first turntable is detachably connected to the frame, and the first driving member is used to drive the first turntable to rotate axially in a first direction.

[0013] In the technical solution of the embodiment of the present application, the first turntable is detachably connected to the frame, which makes it easy to remove the empty positioning assembly from the frame and then replace it with the positioning assembly filled with springs. The frame is then used to send the positioning assembly filled with springs to the loading position. The first driving member is used to drive the first turntable to rotate axially in the first direction. The first driving member drives the first turntable and the second turntable to rotate so as to rotate the corresponding spring to the corresponding position for grabbing. Through mechanical cooperation, the spring loading process is more continuous and faster.

[0014] In some embodiments, it also includes a first plate, a second plate and a plurality of ball bearings, the opposite surfaces of the first plate and the second plate are provided with annular grooves for placing the ball bearings, the plurality of ball bearings are supported between the first plate and the second plate, the first driving member is fixed to the first plate, the second plate is connected to the output end of the first driving member, and the second plate supports the first turntable.

[0015] In the technical solution of the embodiment of the present application, annular grooves for placing ball bearings are provided on the opposing surfaces of the first plate and the second plate, a plurality of ball bearings are supported between the first plate and the second plate, the second plate is connected to the output end of the first driving member, the axis of rotation of the second plate driven by the first output member is coaxial with the annular grooves on the opposing surfaces of the first plate and the second plate, the second plate supports the first turntable and drives the first turntable to rotate, the second plate provides a support surface for the first turntable, so that the weight of the positioning assembly and the spring can be dispersed on the support surface in contact with the second plate, reducing the risk of deformation of the positioning assembly due to stress concentration caused by the large weight of the loaded spring and the small area of ​​the support surface.

[0016] In some embodiments, a surface of the second plate facing away from the first plate is provided with a plurality of protrusions, and the first turntable is provided with a plurality of limiting openings for the protrusions to pass through, and the plurality of protrusions are matched with the plurality of limiting openings one by one.

[0017] In the technical solution of the embodiment of the present application, a plurality of protrusions are provided on the surface of the second plate facing away from the first plate, and a plurality of limiting openings are provided on the first turntable. When the first turntable is placed on the second plate, the plurality of protrusions match with the plurality of limiting openings one by one, and the protrusions are inserted into the limiting openings. The cooperation between the protrusions and the limiting openings limits the rotation of the first turntable relative to the second plate, so that the force of the first driving member driving the first turntable to rotate can be stably transmitted to the first turntable.

[0018] In some embodiments, a support assembly is also included, which includes a second driving member and a support block. The second driving member is arranged on the first plate, and the support block is arranged at the output end of the second driving member. The second driving member drives the support block to rise or fall in a first direction to lift the positioning assembly from the frame and then place it on the second plate after the frame leaves.

[0019] In the technical solution of the embodiment of the present application, the support assembly includes a second drive member and a support block, the support block is used to support the first turntable, the contact area between the support block and the first turntable is large, so that the weight of the positioning assembly and the spring can be evenly dispersed on the contact surface between the first turntable and the support block, reducing the risk of deformation and damage to the supporting area of ​​the first turntable due to excessive concentration of supporting force. The second drive member drives the support block to rise or fall in the first direction to lift the positioning assembly from the second plate or place it on the second plate. The second drive member can drive the support block to lift the positioning assembly off the second plate to facilitate replacement of the positioning assembly. When the second drive member drives the support block to place the positioning assembly on the second plate, the support block can support the bottom surface of the first turntable, reducing the risk of deformation or flipping of the first turntable.

[0020] In some embodiments, the number of the supporting components is multiple, and the multiple supporting components are arranged around the second plate.

[0021] In the technical solution of the embodiment of the present application, multiple support components are arranged around the second plate, and the multiple support components can lift or put down the positioning component at the same time. The positioning component is supported by the multiple support components, reducing the risk of flipping caused by the center of gravity offset of the positioning component.

[0022] In some embodiments, the support shaft is a telescopic rod, and the support shaft is telescopic to change the spacing distance between the first turntable and the second turntable.

[0023] In the technical solution of the embodiment of the present application, the support shaft is a telescopic rod, which is telescopic to change the spacing distance between the first turntable and the second turntable, so that the spacing distance between the first turntable and the second turntable can be adapted to the use of springs of different lengths, so that a part of the spring inserted in the positioning shaft can pass through the positioning hole, and the length of the part of the spring that exceeds the second turntable in the first direction is sufficient for the loading equipment (robotic arm, etc.) to grasp it, thereby improving the versatility of the shock absorber spring loading auxiliary device provided by the present application.

[0042] Taking the positioning assembly 2 as an example, the position close to the first rotating disk 20 is the bottom, and the position close to the second rotating disk 21 is the top.

[0043] The X direction shown in the figure is the first direction X.

[0044] In the first direction X, the top of the spring 1 exceeds the top surface of the second rotating disk 21 .

[0045] There may be a gap between the positioning shaft 3 and the second rotating disk 21 ; or, the positioning shaft 3 may pass through the positioning hole 210 .

[0046] The diameter of the positioning shaft 3 is smaller than the inner diameter of the spring 1 .

[0047] The diameter of the positioning hole 210 may be slightly larger than the outer diameter of the spring 1 .

[0048] There may be a plurality of support shafts 22 , and the plurality of support columns are disposed around the axis of the first turntable 20 and the second turntable 21 .

[0049] The number of the plurality of positioning axes 3 may be twenty, twenty-five, thirty, thirty-five, forty, forty-five, fifty, fifty-five, sixty or more.

[0050] The auxiliary device for feeding the shock absorber spring 1 includes a positioning component 2 including a first turntable 20, a second turntable 21 and a support shaft 22. The first turntable 20 and the second turntable 21 are connected by the support shaft 22, so that there is a certain gap between the first turntable 20 and the second turntable 21; the positioning shaft 3 is arranged on the first turntable 20 around the axis of the first turntable 20, and the positioning shaft 3 extends along the first direction X to guide the spring 1 inserted in the positioning shaft 3 to be vertical along the first direction X. The first turntable 20 is used to support the spring 1, and the positioning shaft 3 is used to insert the spring 1; wherein, the second turntable 21 is provided with a plurality of positioning holes 210, and the plurality of positioning holes 210 correspond one by one to the plurality of positioning shafts 3. The positioning holes 210 are used for the spring 1 to pass through, and a part of the spring 1 inserted in the positioning shaft 3 passes through the positioning holes 210. The positioning holes 210 limit the position of the head of the spring 1 to avoid the positioning component 2, multiple springs 1 placed on the feeding auxiliary device are entangled or interlaced with each other, so that the feeding device (mechanical arm) will only grab one spring 1 at a time, and the positioning shaft 3 limits the position of the bottom of the spring 1 and guides the spring 1 to remain vertical; in actual use of the shock absorber spring 1 feeding auxiliary device provided by the present application, the springs 1 that fill all the positioning holes 210 or positioning shafts 3 of a shock absorber spring 1 feeding auxiliary device are considered as a batch. After the worker fills a shock absorber spring 1 feeding auxiliary device with springs 1, the shock absorber spring 1 feeding auxiliary device with a batch of springs 1 is sent to the feeding position. After the springs 1 are taken out, a new shock absorber spring 1 feeding auxiliary device with a batch of springs 1 is immediately replaced, and the springs 1 are sent to the feeding position in batches, avoiding the influence of the slow speed of manual spring sorting on the feeding speed of the spring 1, so that the feeding process of the spring 1 remains uniform and fast.

[0051] According to some embodiments of the present application, optionally, Figure 2 , Figure 4 and Figure 6 As shown, in the first direction X, the dimension of the positioning axis 3 is h, which satisfies 12 cm ≤ h ≤ 18 cm.

[0052] When h is less than 12 cm, the length of the positioning shaft 3 is shorter, the size of the portion of the spring 1 sleeved on the positioning shaft 3 and limited by the positioning shaft 3 is smaller, and the risk of the portion of the spring 1 not guided by the positioning shaft 3 being bent and intertwined with other springs 1 is higher.

[0053] In the first direction X, the size of the positioning axis 3 is h. When 12cm≤h≤18cm is satisfied, the size of the portion of the spring 1 that is restricted from bending by the positioning axis 3 is longer, so that the effect of keeping the spring 1 in a vertical state is better. At the same time, after the spring 1 is grabbed by the feeding equipment, the spring 1 needs to move a shorter distance along the first direction X to allow the spring 1 to escape from the limit of the positioning axis 3, thereby reducing the risk of the spring 1 bending due to the lateral movement of the spring 1 when the spring 1 is grabbed due to the distance it moves along the first direction X is not enough to allow the spring 1 to escape from the positioning axis 3.

[0054] According to some embodiments of the present application, optionally, Figure 1 to Figure 6 As shown, the vehicle frame 4 is also included. The vehicle frame 4 is provided with running wheels 40 , and the positioning assembly 2 is rotatably arranged on the vehicle frame 4 .

[0055] The number of the running wheels 40 may be four, five, six, seven, eight, nine, ten or more.

[0056] The running wheel 40 can be a straight-running wheel, an omnidirectional wheel, a ball wheel, a universal wheel, etc.

[0057] The frame 4 is provided with running wheels 40, and the positioning assembly 2 with the springs 1 placed thereon is moved on the ground or the work platform by the running wheels 40, thereby reducing the difficulty of transporting batches of springs 1. The positioning assembly 2 is rotatably arranged on the frame 4, and the positioning assembly 2 can deliver the next grasped spring 1 to the grasping position of the loading equipment (mechanical arm, etc.) by rotation, thereby reducing the path that the loading equipment needs to move to grasp the spring 1, thereby reducing the time required for loading the spring 1 and accelerating the production rate of the shock absorber.

[0058] According to some embodiments of the present application, optionally, Figure 1 to Figure 4 and Figure 6 As shown, the frame 4 is further provided with a first driving member 41, which is placed on the frame 4, and the first turntable 20 is detachably connected to the frame 4. The first driving member 41 is used to drive the first turntable 20 to rotate axially in the first direction X.

[0059] The first turntable 20 can be connected to the frame 4 by threads, snaps, pins, latches, hinges, etc.; or, the first turntable 20 can be supported by the frame 4.

[0060] The first turntable 20 is detachably connected to the frame 4, so that an empty positioning assembly 2 can be removed from the frame 4 and then replaced with a positioning assembly 2 filled with springs 1. The positioning assembly 2 filled with springs 1 can then be sent to the loading position using the frame 4. The first driving member 41 is used to drive the first turntable 20 to rotate axially in the first direction X. The first driving member 41 drives the first turntable 20 and the second turntable 21 to rotate so as to rotate the corresponding spring 1 to the corresponding position for grabbing. Through mechanical cooperation, the loading process of the spring 1 is made more continuous and faster.

[0061] According to some embodiments of the present application, optionally, Figure 1-2 , Figure 4-5As shown, it also includes a first plate 42, a second plate 43 and a plurality of ball bearings 44. The opposite surfaces of the first plate 42 and the second plate 43 are provided with annular grooves for placing the ball bearings 44. The plurality of ball bearings 44 are supported between the first plate 42 and the second plate 43. The first driving member 41 is fixed to the first plate 42. The second plate 43 is connected to the output end of the first driving member 41. The second plate 43 supports the first turntable 20.

[0062] On a plane perpendicular to the first direction X, the size of the first plate 42 may be larger than that of the second plate 43 , and the size of the second plate 43 may be smaller than that of the first turntable 20 .

[0063] The plurality of balls 44 are arranged in a ring shape along the annular groove, and the connection between the output end of the first driving member 41 and the second plate 43 is located at the center of the circle surrounded by the plurality of balls 44 .

[0064] The opposing surfaces of the first plate 42 and the second plate 43 are provided with annular grooves for placing balls 44, and a plurality of balls 44 are supported between the first plate 42 and the second plate 43. The second plate 43 is connected to the output end of the first driving member 41. The axis of rotation of the second plate 43 driven by the first output member is coaxial with the annular grooves on the opposing surfaces of the first plate 42 and the second plate 43. The second plate 43 supports the first turntable 20 and drives the first turntable 20 to rotate. The second plate 43 provides a supporting surface for the first turntable 20, so that the weight of the positioning assembly 2 and the spring 1 can be dispersed on the supporting surface in contact with the second plate 43, thereby reducing the risk of deformation of the positioning assembly 2 due to stress concentration caused by the large weight of the loaded spring 1 and the small area of ​​the supporting surface.

[0065] According to some embodiments of the present application, optionally, Figure 2 As shown, a plurality of protrusions 430 are provided on the surface of the second plate 43 facing away from the first plate 42, and a plurality of limiting openings are provided on the first turntable 20 for the protrusions 430 to pass through, and the plurality of protrusions 430 are matched with the plurality of limiting openings one by one.

[0066] The number of the plurality of protrusions 430 may be two, three, four, five, six, seven, eight, nine, or ten.

[0067] The number of the plurality of protrusions 430 is preferably two.

[0068] At least one protrusion 430 among the plurality of protrusions 430 is disposed at the axis of the first rotating disk 20 , and the other protrusions 430 are disposed around the axis of the first rotating disk 20 .

[0069] Among the plurality of protrusions 430 , the size of the protrusion 430 disposed at the axis center of the first rotating disk 20 is larger than that of the other protrusions 430 .

[0070] A plurality of protrusions 430 are provided on the surface of the second plate 43 facing away from the first plate 42, and a plurality of limiting openings are provided on the first turntable 20 for the protrusions 430 to pass through. When the first turntable 20 is placed on the second plate 43, the plurality of protrusions 430 cooperate with the plurality of limiting openings one by one, and the protrusions 430 are inserted into the limiting openings. The cooperation between the protrusions 430 and the limiting openings restricts the first turntable 20 from rotating relative to the second plate 43, so that the force of the first driving member 41 driving the first turntable 20 to rotate can be stably transmitted to the first turntable 20.

[0071] According to some embodiments of the present application, optionally, Figure 1 to Figure 6 As shown, it also includes a support assembly 5, which includes a second driving member 50 and a support block 51. The second driving member 50 is arranged on the first plate 42, and the support block 51 is arranged at the output end of the second driving member 50. The second driving member 50 drives the support block 51 to rise or fall along the first direction X to lift the positioning assembly 2 from the second plate 43 or place it on the second plate 43.

[0072] The position where the support block 51 supports the first turntable 20 is the area where the first turntable 20 exceeds the second plate 43 and faces the first plate 42 .

[0073] The support assembly 5 includes a second driving member 50 and a support block 51. The support block 51 is used to support the first turntable 20. The contact area between the support block 51 and the first turntable 20 is large, so that the weight of the positioning assembly 2 and the spring 1 can be evenly distributed on the contact surface between the first turntable 20 and the support block 51, reducing the risk of deformation and damage of the supporting area of ​​the first turntable 20 due to excessive concentration of the supporting force. The second driving member 50 drives the support block 51 to rise or fall along the first direction X to lift the positioning assembly 2 from the frame 4 and then place it on the second plate 43 after the frame 4 leaves. The second driving member 50 can drive the support block 51 to lift the positioning assembly 2 from the second plate 43 to facilitate replacement of the positioning assembly 2.
