Description

Technical Field

[0001] This utility model belongs to the technical field of spring processing equipment, and specifically relates to an end face processing device for spring production. Background Technology

[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. During the manufacturing process of a spring, both end faces need to be ground to prevent burrs or protrusions from forming on the end faces.

[0003] Currently, Chinese utility model patent CN221185827U discloses a spring end-face processing device, including a processing base plate. A support frame is fixedly connected to the top of the processing base plate. A groove is formed on the surface of the support frame, and two sliders are slidably connected inside the groove. Threaded rods are threaded inside the two sliders. A rotating shaft is rotatably connected inside the support frame, and the front end of the rotating shaft is fixedly connected to the rear end of the threaded rod. A storage device is provided inside the processing base plate. In this spring end-face processing device, the two sliders slide back and forth, causing two arc-shaped pressure plates to slide back and forth and press against the inner surface of the spring. The two arc-shaped pressure plates can press and fix the inner surface of the spring, thereby preventing the spring from deforming. This not only improves the stability of the spring during end-face grinding but also prevents damage to the spring during production and processing, thus improving the processing quality of the spring.

[0004] In summary, although the device can achieve the function of polishing springs, there are still some problems in its use. For example, it uses single-sided polishing and cannot polish both sides at the same time. After polishing, it is necessary to change sides, which undoubtedly reduces the efficiency and speed of polishing. Utility Model Content

[0005] The purpose of this utility model is to provide an end face processing device for spring production, which has the advantages of double-sided grinding and applicability to springs of different lengths.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a face processing device for spring production, comprising a processing table, a support base bolted to the top of the processing table, brackets symmetrically arranged on the top of the processing table, rotating sleeves rotatably connected to opposite sides of the two brackets, a connecting rod rotatably connected inside the support base and slidably engaged with the rotating sleeve, a rotating shaft rotatably connected to one end of the bracket, a transmission mechanism provided between the rotating shaft and the rotating sleeve, a grinding disc mounted at one end of the rotating shaft, a drive motor mounted on one side of the support base, the output end of the drive motor bolted to the connecting rod, a sliding groove provided on the support base, a first bidirectional threaded rod provided on the back of the support base, and the other end of the bracket penetrating to the back of the support base and threadedly connected to the first bidirectional threaded rod.

[0007] The above technical solution is as follows: This utility model has a rotating sleeve installed on the bracket, and a connecting rod that is slidably engaged with the rotating sleeve inside the support base. When the drive motor is started, it can drive the connecting rod to rotate, which in turn drives the rotating sleeve to rotate. Under the action of the transmission mechanism, it drives the rotating shaft to rotate, thereby completing the simultaneous rotation of the grinding discs installed on the two brackets. When the spring is placed between the two grinding discs, both ends of the spring can be ground simultaneously, improving the grinding efficiency. The back of the support base is designed with a first bidirectional threaded rod. When the first bidirectional threaded rod is rotated, the distance between the two brackets can be adjusted, thereby driving the grinding discs installed on the brackets to move. The distance between the two grinding discs can be adjusted to make it suitable for grinding the two end faces of springs of different lengths.

[0008] The present invention is further configured such that the transmission mechanism includes two synchronous pulleys respectively fixedly sleeved to the rotating shaft and the rotating sleeve, and a synchronous belt is drivingly connected between the two synchronous pulleys.

[0009] The above technical solution is adopted as follows: when the drive motor starts, it can drive the connecting rod to rotate. The rotation of the connecting rod can drive the rotating sleeve to rotate, thereby rotating the synchronous wheel installed on the rotating sleeve. Under the action of the synchronous belt, the synchronous wheel on the rotating shaft will rotate, which in turn drives the grinding disc to rotate.

[0010] The present invention is further configured such that protective covers are fixedly connected to the opposite sides of the two brackets, the rotating shaft and the rotating sleeve are rotatably connected to the protective covers, and protective cover plates are fitted to the opposite sides of the two protective covers, the protective cover plates being rotatably connected to the rotating shaft and the rotating sleeve.

[0011] The above technical solution is adopted to protect the transmission mechanism and prevent dust from falling into it.

[0012] The present invention is further configured such that the top of the processing table is symmetrically provided with limit seats, and rubber pads are fitted on the opposite sides of the two limit seats.

[0013] The above technical solution involves clamping the spring and using a rubber pad to improve its anti-slip properties.

[0014] The present invention is further configured such that an adjusting seat is mounted on the top of the processing table, and a second bidirectional threaded rod is rotatably connected inside the adjusting seat. The surface of the second bidirectional threaded rod is symmetrically threaded with a connecting seat that is fixedly connected to the limiting seat, and the connecting seat is slidably connected to the adjusting seat.

[0015] The above technical solution is adopted: when the second bidirectional threaded rod is rotated, the two connecting seats can be moved, thereby adjusting the distance between the two limit seats so that the two limit seats can clamp springs of different sizes.

[0016] The present invention is further configured such that a limiting block is symmetrically fixed to the back of the support base, and the limiting block is rotatably connected to the first bidirectional threaded rod.

[0017] The above technical solution is adopted to limit the rotation of the first bidirectional threaded rod.

[0018] The present invention is further configured such that guide grooves are symmetrically provided inside the sliding groove, and guide blocks that are slidably connected to the guide grooves are mounted on the bracket.

[0019] The above technical solution is adopted: the bracket is slidably limited.

[0020] In summary, this utility model has the following beneficial effects: 1. This utility model has a rotating sleeve installed on the bracket, and a connecting rod that is slidably engaged with the rotating sleeve inside the support base. When the drive motor is started, it can drive the connecting rod to rotate, which in turn drives the rotating sleeve to rotate. Under the action of the transmission mechanism, the rotating shaft is driven to rotate, thereby completing the simultaneous rotation of the grinding discs installed on the two brackets. When the spring is placed between the two grinding discs, both ends of the spring can be ground at the same time, improving the grinding efficiency. 2. This utility model has a first bidirectional threaded rod designed on the back of the support base. When the first bidirectional threaded rod is rotated, the distance between the two brackets can be adjusted, thereby moving the grinding discs mounted on the brackets. The distance between the two grinding discs can be adjusted to make it suitable for grinding the two end faces of springs of different lengths. Attached Figure Description

[0023] The present invention will be further described in detail below with reference to the accompanying drawings.

[0024] Example 1: refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A spring end-face processing device includes a processing table 1, a support base 2 bolted to the top of the processing table 1, and brackets 3 symmetrically arranged on the top of the processing table 1. Rotary sleeves 4 are rotatably connected to opposite sides of the two brackets 3. A connecting rod 5, which is slidably engaged with the rotating sleeve 4, is rotatably connected inside the support base 2. A rotating shaft 6 is rotatably connected to one end of the bracket 3. A transmission mechanism 7 is provided between the rotating shaft 6 and the rotating sleeve 4. A grinding disc 8 is mounted on one end of the rotating shaft 6. A drive motor 9 is mounted on one side of the support base 2. The output end of the drive motor 9 is bolted to the connecting rod 5. By mounting the rotating sleeve 4 on the bracket 3 and the connecting rod 5, which is slidably engaged with the rotating sleeve 4 inside the support base 2, when the drive motor 9 is started, it can drive the connecting rod 5 to rotate, thereby driving the rotating sleeve 4 to rotate. Under the action of the transmission mechanism 7, the rotating shaft 6 is driven to rotate, thus completing the simultaneous rotation of the grinding discs 8 mounted on the two brackets 3. When the spring is placed between the two grinding discs 8, both ends of the spring can be ground simultaneously, improving grinding efficiency.

[0025] refer to Figure 3The transmission mechanism 7 includes two synchronous pulleys 71 that are fixedly sleeved to the rotating shaft 6 and the rotating sleeve 4 respectively. A synchronous belt 72 is connected between the two synchronous pulleys 71. By setting the synchronous pulleys 71 and the synchronous belt 72, when the drive motor 9 starts, it can drive the connecting rod 5 to rotate. The rotation of the connecting rod 5 can drive the rotating sleeve 4 to rotate, thereby rotating the synchronous pulleys 71 installed on the rotating sleeve 4. Under the action of the synchronous belt 72, the synchronous pulleys 71 on the rotating shaft 6 are driven to rotate, which in turn drives the grinding disc 8 to rotate.

[0026] refer to Figure 1 and Figure 3 Each of the two supports 3 has a protective cover 12 fixedly attached to one side opposite to the other. The rotating shaft 6 and the rotating sleeve 4 are rotatably connected to the protective cover 12. Each of the two protective covers 12 has a protective cover 13 mounted on one side opposite to the other. The protective cover 13 is rotatably connected to the rotating shaft 6 and the rotating sleeve 4. By setting the protective cover 12 and the protective cover 13, the transmission mechanism 7 is protected to prevent dust from falling onto the transmission mechanism 7.

[0027] refer to Figure 1 and Figure 4 The top of the processing table 1 is symmetrically provided with limit holders 14. Each of the two limit holders 14 is equipped with a rubber pad 15 on the opposite side. By setting the limit holders 14 and the rubber pads 15, the spring is clamped. The rubber pads 15 can improve the anti-slip properties of the spring.

[0028] refer to Figure 1 and Figure 4 The top of the processing table 1 is equipped with an adjustment seat 16. The interior of the adjustment seat 16 is rotatably connected to a second bidirectional threaded rod 17. The surface of the second bidirectional threaded rod 17 is symmetrically threaded with a connecting seat 18 that is fixedly connected to the limiting seat 14. The connecting seat 18 is slidably connected to the adjustment seat 16. By setting the adjustment seat 16, the second bidirectional threaded rod 17 and the connecting seat 18, when the second bidirectional threaded rod 17 is rotated, the two connecting seats 18 can be moved, thereby adjusting the distance between the two limiting seats 14, so that the two limiting seats 14 can clamp springs of different sizes.

[0029] Brief description of the usage process: Place the spring between the two limit holders 14 and make the two limit holders 14 engage the spring. Start the drive motor 9, which can drive the connecting rod 5 to rotate, and then drive the rotating sleeve 4 to rotate. Under the action of the transmission mechanism 7, the rotating shaft 6 is driven to rotate, thereby completing the simultaneous rotation of the grinding discs 8 installed on the two brackets 3. When the spring is placed between the two grinding discs 8, both ends of the spring can be ground at the same time, improving the grinding efficiency.

[0030] Example 2: refer to Figure 1 and Figure 2 A face processing device for spring production includes a processing table 1, a support base 2 bolted to the top of the processing table 1, and brackets 3 symmetrically arranged on the top of the processing table 1. Rotary sleeves 4 are rotatably connected to opposite sides of each of the two brackets 3. A connecting rod 5, which is slidably engaged with the rotating sleeve 4, is rotatably connected inside the support base 2. A rotating shaft 6 is rotatably connected to one end of each bracket 3. A transmission mechanism 7 is provided between the rotating shaft 6 and the rotating sleeve 4. A grinding disc 8 is mounted on one end of the rotating shaft 6. A drive motor 9 is mounted on one side of the support base 2. The output end of the drive motor 9 is connected to the connecting rod 5. The support base 2 is bolted together and has a sliding groove 10. A first bidirectional threaded rod 11 is provided on the back of the support base 2. The other end of the bracket 3 passes through the back of the support base 2 and is threadedly connected to the first bidirectional threaded rod 11. The first bidirectional threaded rod 11 is designed on the back of the support base 2. When the first bidirectional threaded rod 11 is rotated, the distance between the two brackets 3 can be adjusted, thereby moving the grinding disc 8 installed on the bracket 3. The distance between the two grinding discs 8 can be adjusted to make it suitable for grinding the two ends of springs of different lengths.

[0031] refer to Figure 2 A limiting block 19 is symmetrically fixed to the back of the support base 2. The limiting block 19 is rotatably connected to the first bidirectional threaded rod 11. By setting the limiting block 19, the rotation of the first bidirectional threaded rod 11 is limited.

[0032] refer to Figure 1 and Figure 2 The sliding groove 10 has symmetrically opened guide grooves 20 inside, and the bracket 3 is equipped with a guide block 21 that is slidably connected to the guide groove 20. By setting the guide groove 20 and the guide block 21, the bracket 3 is slidably limited.

[0033] Brief description of the usage process: When the first bidirectional threaded rod 11 is rotated, the distance between the two brackets 3 can be adjusted, and the distance between the two rotating shafts 6 can be adjusted, thereby moving the grinding disc 8 installed on the rotating shaft 6. Furthermore, the connecting rod 5 and the rotating sleeve 4 are slidably engaged. When the rotating sleeve 4 slides on the surface of the connecting rod 5, it does not affect the connecting rod 5 from rotating the rotating sleeve 4, and thus does not affect the rotating sleeve 4 from rotating the rotating shaft 6 under the action of the transmission mechanism 7. The distance between the two grinding discs 8 can be adjusted to make it suitable for grinding the two ends of springs of different lengths.

[0034] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
