Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of spring processing equipment, and specifically relates to a spring end face grinding device. Background Technology
[0002] A spring is a mechanical part that works by utilizing elasticity. Parts made of elastic materials deform under external force and return to their original shape after the force is removed. The two ends of a spring generally need to be ground flat to ensure even force distribution. Currently, spring end face grinding is mainly done by hand holding the spring while grinding it on a grinding machine. This method is extremely inefficient, unsuitable for mass production, and makes it difficult to control the flatness of the surface.
[0003] Chinese utility model patent CN215999800U discloses a face grinding device for spring processing, including a base, a movable plate, a limiting movable plate, a grinding shaft mounting plate, a turntable, and several grinding shafts. The grinding shaft mounting plate is fixed on the base, and the several grinding shafts pass through the grinding shaft mounting plate and are rotatably connected to it. One end of each grinding shaft has a through hole, and the other end is fixedly connected to a connecting arm. The connecting arm is connected to the turntable via a connecting shaft. The turntable is connected to a drive motor via a "Z"-shaped drive shaft. The drive motor sits on a first mounting platform. The movable plate and the limiting movable plate are slidably mounted on the base, and the limiting movable plate has several through holes. Several insert shafts are fixed at positions corresponding to the through holes on the end face of the movable plate. The insert shafts pass through the through holes and are movably inserted into the through holes on the grinding shafts. The back of the movable plate with the insert shafts is connected to a first cylinder via a telescopic shaft. The first cylinder sits on a second mounting platform.
[0004] During use, the aforementioned patent does not have a debris collection mechanism, and the metal debris generated during grinding is prone to accumulate in the gaps between the equipment or on the surface of the spring, which not only pollutes the processing environment but may also aggravate equipment wear or scratch the surface of the spring. Secondly, the turntable and drive shaft that drive the grinding shaft are complex to set up, which takes up space and is not very stable. Furthermore, this device cannot adjust the hole diameter of the limit moving plate and the diameter of the pin according to the size of the spring. Utility Model Content
[0005] In view of the above-mentioned shortcomings in the prior art, the present invention provides a spring end face grinding device to solve the problems in the background art.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A spring end face grinding device, comprising a base, wherein a moving assembly, a rotating assembly and a collecting assembly are mounted on the base, and the base is symmetrically provided with slide rails, as well as a first slider and a second slider slidably mounted on the slide rails; the moving assembly comprises a first support block fixedly mounted on the base, a first cylinder and a second cylinder fixed on the first support block, a T-shaped connecting rod fixedly connected with the telescopic rod of the first cylinder, a limiting plate fixedly connected with the end of the T-shaped connecting rod away from the first cylinder, a C-shaped connecting frame fixedly connected with the telescopic rod of the second cylinder, and a first fixing plate fixedly connected with the end of the connecting frame away from the second cylinder; the bottom of the limiting plate is connected with the first slider, and the bottom of the first fixing plate is fixedly connected with the second slider; the rotating assembly comprises a second support block fixedly mounted on the base, a servo motor fixed on the second support block, a gear set connected with the output end of the servo motor, and a grinding shaft driven to rotate by the gear set; the moving assembly and the rotating assembly are arranged opposite to each other in the horizontal direction; the collecting assembly comprises a funnel-shaped collecting trough located below the grinding shaft and fixed on the base, a collecting hole opened at the bottom of the collecting trough, and a collecting pipe communicated with the collecting hole.
[0007] Further, the T-shaped connecting rod penetrates through the middle part of the first fixing plate and is fixedly connected with the limiting plate; a mounting block is arranged on the side of the first fixing plate facing the limiting plate, a horizontally arranged mounting rod is in threaded connection with the mounting block, and the axis of the mounting rod coincides with the axis of the grinding shaft.
[0008] Further, the middle part of the mounting rod penetrates through the limiting plate and is in clearance fit with the limiting plate, and its end away from the first fixing plate is inserted into a positioning hole opened at the end of the grinding shaft.
[0009] Further, the limiting plate is in a shape of "convex", and through holes perpendicular to the direction of the slide rails are arranged on both sides of its protruding part; the side of the first slider is provided with mounting holes corresponding to the through holes, and the limiting plate and the first slider are fixed by screws passing through the through holes and the mounting holes.
[0010] Further, the gear set comprises a driving gear fixedly connected with the output end of the servo motor and a driven gear meshed with the driving gear.
[0011] Further, the driven gear is fixedly connected with the end of the grinding shaft away from the mounting rod.
[0012] Further, a second fixing plate is fixed on the base, and the middle part of the grinding shaft penetrates through the second fixing plate and is rotatably connected with the second fixing plate.
[0013] Compared with the prior art, the utility model has the following beneficial effects: 1. The limiting plate and the first slider are detachably connected by screws, and the mounting rod and the mounting block are detachably engaged by threads. When processing springs of different diameters, simply unscrew the screws and replace the limiting plate with the corresponding size (such as adjusting the through hole size to adapt to springs of different wire diameters), rotate and remove the mounting rod to replace it with a specification that matches the length and diameter. Without modifying the main structure of the device, it can quickly adapt to diverse processing needs and significantly improve the versatility of the equipment.
[0014] 2. The mounting rod and the grinding shaft axis are strictly aligned. With the rigid limiting plate, the spring sleeve can form stable radial support and axial positioning. At the same time, the first and second sliders slide independently along the slide rail. The positions of the limiting plate and the mounting rod are adjusted by the first and second cylinders respectively, which can accurately control the contact pressure between the spring and the grinding shaft, reducing the problem of insufficient grinding flatness caused by positioning deviation. Meanwhile, the gear transmission is stable, and the servo motor can accurately control the grinding shaft speed, ensuring consistent grinding flatness of the spring end face.
[0015] 3. The funnel-shaped collection trough, in conjunction with the collection components of an external dust collection device, can remove grinding debris in real time, preventing debris from accumulating in the grinding area and affecting processing accuracy. At the same time, it reduces the cleaning workload of operators, reduces wear and tear on moving parts of the equipment caused by metal debris, and extends the service life of the device.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0020] In the description of this utility model, unless otherwise explicitly specified and limited, the term "connection" or similar designation indicating the connection relationship between components should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Example 1: like Figure 1-5 As shown, this utility model provides a spring end face grinding device, comprising a base 1. A moving component, a rotating component, and a collecting component are mounted on the base 1. These functional components are assembled in an orderly manner to achieve efficient grinding of the spring end face. Two parallel slide rails 16 are symmetrically arranged on the top of the base 1. Two first sliders 14 and a second slider 17 are slidably mounted on the slide rails 16, providing guiding support for the translation of the moving component.
[0022] In this embodiment, the moving component includes a first support block 11 fixedly mounted on the base 1, a first cylinder 2 and a second cylinder 132 fixedly mounted on the first support block 11, a T-shaped connecting rod 21 fixedly connected to the telescopic rod of the first cylinder 2, a limiting plate 22 fixedly connected to the end of the T-shaped connecting rod 21 away from the first cylinder 2, a C-shaped connecting frame 133 fixedly connected to the telescopic rod of the second cylinder 132, and a first fixing plate 13 fixedly connected to the end of the connecting frame 133 away from the second cylinder 132. The bottom of the limiting plate 22 is connected to the first slider 14, and the bottom of the first fixing plate 13 is fixedly connected to the second slider 17. The limiting plate 22 is convex, and its protruding part has through holes perpendicular to the direction of the slide rail 16 on both sides. The side of the first slider 14 has mounting holes corresponding to the through holes. The limiting plate 22 and the first slider 14 are fixed by screws 15 passing through the through holes and mounting holes, ensuring that the limiting plate 22 can slide stably along the slide rail 16 with the first slider 14. Figure 5 As shown, the U-shaped connecting bracket 133 is connected to both ends of the first fixing plate 13. This specific shape design ensures that the two cylinders will not interfere with each other.
[0023] Meanwhile, the T-shaped connecting rod 21 passes through the middle of the first fixing plate 13 and is fixedly connected to the limiting plate 22. The first fixing plate 13 has a mounting block 131 on the side facing the limiting plate 22. A horizontally arranged mounting rod 23 is threaded onto the mounting block 131, and the axis of the mounting rod 23 coincides with the axis of the grinding shaft 33. The middle part of the mounting rod 23 passes through the limiting plate 22 and is clearance-fitted with it. The end of the mounting rod away from the first fixing plate 13 is inserted into the positioning hole 331 at the end of the grinding shaft 33.
[0024] In this embodiment, the moving component and the rotating component are arranged opposite each other in the horizontal direction.
[0025] The rotating assembly includes a second support block 12 fixedly mounted on the base 1, a servo motor 3 fixedly mounted on the second support block 12, a gear set 31 connected to the output end of the servo motor 3, and a grinding shaft 33 driven to rotate by the gear set 31. The gear set 31 includes a driving gear 311 fixedly connected to the output end of the servo motor 3 and a driven gear 312 meshing with the driving gear 311. The driven gear 312 is fixedly connected to the end of the grinding shaft 33 away from the mounting rod 23. A second fixing plate 32 is fixed on the base 1, and the middle part of the grinding shaft 33 passes through the second fixing plate 32 and is rotatably connected to the second fixing plate 32, which ensures the rotational stability of the grinding shaft 33 and limits its axial position.
[0026] In this embodiment, the collection assembly includes a funnel-shaped collection groove 4 located below the grinding shaft 33 and fixed to the base 1, a collection hole 41 opened at the bottom of the collection groove 4, and a collection tube 42 communicating with the collection hole 41. The collection tube 42 can be connected to an external vacuum cleaner to achieve the purpose of quickly collecting the debris during spring grinding.
[0027] In use, the appropriate mounting rod 23 and limiting plate 22 are selected according to the size of the spring to be ground. The mounting rod 23 is rotated to install it on the mounting block 131, and the limiting plate 22 is fixed on the first slider 14. The spring is sleeved on the mounting rod 23, and the extension or retraction of the telescopic rod of the second cylinder 132 is used to adjust the position of the first fixing plate 13 through the connecting bracket 133. This roughly adjusts the distance between the mounting rod 23 and the limiting plate 22 and the grinding shaft 33, ensuring that the end of the mounting rod 23 away from the first fixing plate 13 can be inserted into the positioning hole 331 of the grinding shaft 33, and one end of the spring abuts against the end face of the limiting plate 22 facing the grinding shaft 33. At this time, the position of the mounting rod 23 is fixed. The first cylinder 2 is activated, and its telescopic rod extends or retracts, driving the limiting plate 22 to move along the slide rail 16 via the T-shaped connecting rod 21. The limiting plate 22 moves towards the grinding shaft 33 until the other end face of the spring is in close contact with the end face of the grinding shaft 33, ensuring that the spring is compressed. This prevents the spring from being affected by its elasticity during subsequent grinding. The servo motor 3 is then activated, and its output shaft drives the drive gear 311 to rotate. The drive gear 311, through meshing transmission, drives the driven gear 312 to rotate, which in turn drives the grinding shaft 33 to rotate. The rotating end face of the grinding shaft 33 rubs against the end face of the spring, achieving the grinding process on the spring end face.
[0028] During the grinding process, metal shavings fall into the collection tank 4 below under the action of gravity. Since the collection tank 4 is funnel-shaped, the shavings will gather towards the collection hole 41 at the bottom and be sucked away by the external dust collection device through the collection pipe 42, thereby avoiding the accumulation of shavings from affecting the grinding accuracy and the normal operation of the equipment.
[0029] After grinding is completed, turn off the servo motor 3, the first cylinder 2, and the second cylinder 132 in sequence. The telescopic rod of the first cylinder 2 retracts, causing the limit plate 22 to move away from the grinding shaft 33; the telescopic rod of the second cylinder 132 retracts, causing the mounting rod 23 to move away from the grinding shaft 33. At this time, the ground spring can be removed from the mounting rod 23.
[0030] If different sizes of springs need to be ground, the limit plate 22 of different specifications can be replaced by removing screw 15, or the position of the first fixing plate 13 can be adjusted to adapt to springs of different lengths, or the mounting rod 23 of different diameters can be replaced to adapt to springs of different inner diameters, so as to achieve the universality of the device.
[0031] The spring to be ground is fitted onto the mounting rod 23, with one end of the spring naturally abutting against the end face of the limiting plate 22. At this point, the first cylinder 2 is activated, and its extension rod extends and pushes the T-shaped connecting rod 21, causing the limiting plate 22 and the first slider 14 to move along the slide rail 16 towards the rotating assembly until the other end face of the spring is in close contact with the end face of the grinding shaft 33. The spring is then compressed to ensure that its elasticity does not affect the grinding effect during subsequent grinding. Subsequently, the servo motor 3 is activated, and its output torque is transmitted to the grinding shaft via the drive gear 311. The moving gear 312 drives the grinding shaft 33 to rotate at a set speed. The end face of the rotating grinding shaft 33 rubs against the end face of the spring, achieving grinding of the spring end face. During the grinding process, metal chips generated fall into the collection groove 4 below under the action of gravity. They are then quickly sucked away by an external dust suction device through the collection hole 41 and collection pipe 42, preventing chip accumulation from affecting the grinding accuracy. When the grinding is completed, the servo motor 3 stops working, the extension rod of the first cylinder 2 retracts, driving the limit plate 22 and the first slider 14 to reset. At this time, the ground spring can be removed, completing one grinding operation. Through the above structural cooperation, the device can stably realize automated grinding of the spring end face, combining processing efficiency and accuracy.
