Description

Technical Field

[0001] This application relates to the field of spring processing, and in particular to a grinding apparatus for double-sided grinding. Background Technology

[0002] Mechanical buffer springs are a common mechanical component used to reduce or eliminate the impact and vibration generated during the operation of mechanical equipment, thereby improving the stability of the equipment. To enhance the stability of the spring in mechanical equipment, grinding equipment is usually used to grind the two ends of the spring flat.

[0003] A Chinese utility model patent with publication number CN213136104U discloses a spring end face grinding machine device, including a main body, a support block connected to the main body, a support cavity formed in the support block, a rotating disk rotatably connected in the support cavity, a grinding tube for placing the spring on the rotating disk, a rotating component for driving the rotating disk to rotate on the main body, a locking component for fixing the spring to the grinding tube, and a grinding component for grinding the spring on the main body. The spring to be ground is placed in the grinding tube, and the rotation of the rotating disk transports the spring to the grinding wheel for grinding, thereby making the end of the spring flat.

[0004] Existing grinding equipment only grinds one end of the spring. After grinding one end, the spring needs to be flipped over and put back into the machine for grinding the other end, resulting in low grinding efficiency. Summary of the Invention

[0005] In order to improve the grinding efficiency of springs, this application provides a grinding device for double-sided grinding.

[0006] The grinding equipment for double-sided grinding provided in this application adopts the following technical solution: A double-sided grinding device includes a machine body, on which a turntable is rotatably mounted. Several placement cylinders are arranged circumferentially on the turntable. A fixing member is provided inside each placement cylinder to fix a spring. Placement holes are provided on each placement cylinder, penetrating both ends along the length of the placement cylinder. Two sets of grinding mechanisms are provided inside the machine body, and the two sets of grinding mechanisms are respectively located at both ends along the length of the placement cylinder. The turntable drives the placement cylinder to rotate between the two sets of grinding mechanisms by rotating.

[0007] By adopting the above technical solution, the spring is fixed inside the placement cylinder, so that both ends of the spring extend out of the placement cylinder from both ends along the length of the placement cylinder. The placement cylinder is transported between two sets of grinding mechanisms by a rotating disk for grinding. The grinding efficiency of the spring is improved by grinding both ends of the spring simultaneously by two sets of grinding mechanisms.

[0008] Optionally, sliding plates are slidably inserted at both ends of the placement cylinder along its length. The sliding plates slide along the length of the placement cylinder, and an abutment plate is horizontally arranged at the end of the sliding plate away from the placement cylinder.

[0009] By adopting the above technical solution, the abutment plate is inserted into the spring near the grinding area along the length of the spring, which can limit the spring from being compressed by force, reduce the probability of the spring being compressed by force during grinding, and thus reduce the probability of poor grinding effect due to spring compression.

[0010] Optionally, a drive spring is provided between the sliding plate and the placement cylinder. The drive spring drives the sliding plate to slide toward the placement cylinder. Both sliding plates have wedge-shaped surfaces at opposite ends. A drive plate is slidably disposed inside the placement cylinder. The drive plate slides toward or away from the sliding plates. Both ends of the drive plate abut against the wedge-shaped surfaces of the two sliding plates respectively. The drive plate slides toward the sliding plates and drives the sliding plates to slide away from each other.

[0011] By adopting the above technical solution, the drive spring and drive block, together with the wedge surface, are used to drive the sliding plate to slide in two directions, thereby realizing the sliding adjustment of the sliding plate.

[0012] Optionally, a drive bolt is rotatably provided on the turntable, the drive bolt passes through the turntable and is inserted into the placement cylinder, and one end of the drive bolt inserted into the placement cylinder is rotatably connected to the drive plate.

[0013] By adopting the above technical solution, the drive bolt is used to drive the drive plate to slide, and at the same time has a fixing function, reducing the probability of the sliding plate sliding due to external force.

[0014] Optionally, the abutment plate has a guide surface at the end opposite to the sliding plate.

[0015] By adopting the above technical solution, the opening of the guide surface can facilitate the insertion of the abutment plate into the spring.

[0016] Optionally, the grinding mechanism includes a grinding table, a grinding motor, and a grinding wheel. The grinding table is mounted on the machine body, the grinding motor is mounted on the grinding table, the grinding motor shaft is oriented towards the placement cylinder, and the grinding wheel is mounted on the grinding motor shaft.

[0017] By adopting the above technical solution, the grinding motor drives the grinding wheel to rotate and grind the spring that rotates to the bottom of the grinding wheel.

[0018] Optionally, a driving component is provided between the machine body and the grinding table, and the driving component drives the grinding table to slide along the height direction of the machine body.

[0019] By adopting the above technical solution, the driving component can drive the grinding mechanism to adjust the height of the grinding wheel, thereby adjusting the grinding wheel according to the overall length of the spring and the grinding amount, and improving the grinding accuracy of the spring.

[0020] Optionally, the machine body is provided with a dust collection device, which includes a dust collection hood located near the grinding mechanism on the machine body, and a dust collection pipe is installed on the dust collection hood.

[0021] By adopting the above technical solution, the dust hood and dust suction pipe can vacuum the grinding area, reducing the probability that grinding debris will accumulate in the machine and affect subsequent grinding.

[0022] Optionally, the dust collection device further includes suction pipes, which are installed on the machine body at the point where the placement cylinder enters the machine body. There are two suction pipes, which are respectively installed at both ends of the length direction of the placement cylinder.

[0023] By adopting the above technical solution, the impurity suction tube is used to absorb impurities at the spring machining end, reducing the impact of impurities on subsequent grinding.

[0024] In summary, this application includes at least one of the following beneficial technical effects: 1. Fix the spring inside the placement cylinder, so that both ends of the spring extend out of the placement cylinder along its length. The placement cylinder is transported between two grinding mechanisms by a rotating disk for grinding. The grinding efficiency of the spring is improved by grinding both ends of the spring simultaneously by the two grinding mechanisms. 2. Insert the abutment plate into the spring along the length of the spring, close to the grinding area. This helps to limit the spring from being compressed by force, reducing the probability of the spring being compressed during grinding, and thus reducing the probability of poor grinding results due to spring compression. 3. The drive spring and drive block, together with the wedge-shaped surface, are used to drive the sliding plate to slide in two directions, thereby realizing the sliding adjustment of the sliding plate. The drive bolt is used to drive the drive plate to slide, and also has a fixing function, reducing the probability of the sliding plate sliding due to external force. 4. The driving component can drive the grinding mechanism to adjust the height of the grinding wheel, thereby adjusting the grinding wheel according to the overall length of the spring and the grinding amount, and improving the grinding accuracy of the spring; 5. The dust hood, together with the dust suction hose, can vacuum the grinding area, reducing the probability that grinding debris will accumulate inside the machine and affect subsequent grinding. 6. The impurity suction tube is used to absorb impurities at the machining end of the spring, reducing the impact of impurities on subsequent grinding. Attached Figure Description

[0031] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0032] This application discloses a grinding device for double-sided grinding, referring to... Figure 1 The system includes a rectangular body 1 vertically mounted on the ground. A work platform 18 is mounted on the body 1. A geared motor 19 is mounted on the ground-facing side of the work platform 18, with its shaft passing through and rotating on the platform. A circular turntable 2 is rotatably mounted on the side of the work platform 18 away from the ground. The turntable 2 is fixed to the shaft of the geared motor 19 and rotates on the work platform 18 via a speed motor. Half of the turntable 2 is located inside the body 1, and half is located outside. Several placement cylinders 3 are evenly installed around the turntable 2. In this embodiment, ten placement cylinders 3 are provided. A fixing member 4 is installed inside each placement cylinder 3 to secure a spring. In this embodiment, the fixing member 4 is a clamping plate, with the clamping plate facing towards or away from the ground. The spring slides along the inner wall of the placement cylinder 3 in one direction, and is clamped and fixed by the sliding of the fixing part 4. The placement cylinder 3 has placement holes 5 that pass through both ends of the length direction of the placement cylinder 3. When the spring is placed in the placement holes 5 of the placement cylinder 3, both ends of the spring extend out of the placement cylinder 3 from both ends of the placement cylinder 3. The machine body 1 is equipped with two sets of grinding mechanisms 6, which are respectively set at both ends of the length direction of the placement cylinder 3. The turntable 2 drives the placement cylinder 3 to rotate between the two sets of grinding mechanisms 6, bringing the spring between the two sets of grinding mechanisms 6 for simultaneous grinding of both ends. The placement cylinder 3 is transported between the two sets of grinding mechanisms 6 for grinding by the turntable. The grinding efficiency of the spring is improved by grinding both ends of the spring simultaneously by the two sets of grinding mechanisms 6.

[0033] Reference Figure 2 The grinding mechanism 6 includes a rectangular grinding table 61 mounted on the machine body 1, a grinding motor 62 mounted on the grinding table 61, and a grinding wheel 63 mounted on the shaft of the grinding motor 62. The shaft of the grinding motor 62 is oriented towards the placement cylinder 3. The grinding motor 62 drives the grinding wheel 63 to rotate and grind the spring that has rotated to the bottom of the grinding wheel 63. A driving component 16 is provided between the machine body 1 and the grinding table 61. The driving component 16 is an electric cylinder. The driving component 16 drives the grinding table 61 to slide along the height direction of the machine body 1. The driving component 16 can drive the grinding mechanism 6 to adjust the height of the grinding wheel 63, thereby adjusting the grinding wheel 63 according to the overall length of the spring and the amount of grinding, and improving the grinding accuracy of the spring.

[0034] Reference Figure 2 and Figure 3Sliding plates 7 are slidably inserted at both ends of the placement cylinder 3 along its length. The sliding plates 7 slide along the length of the placement cylinder 3. An abutment plate 8 is horizontally positioned at the end of the sliding plate 7 facing away from the placement cylinder 3. A guide surface 15 is provided at the end of the abutment plate 8 facing away from the sliding plate 7. The abutment plate 8 is guided by the guide surface 15 and inserted into the gap of the next ring of the spring to be processed area, abutting against the ring containing the spring to be processed area. During grinding, the abutment plate 8 can prevent the spring from being compressed, thereby reducing the probability of the spring being compressed when the grinding wheel 63 grinds the spring, and reducing the probability of poor grinding effect due to spring compression. The sliding of the sliding plate 7 can carry... The movable abutment plate 8 adjusts its abutment position, thereby adjusting the insertion position of the abutment plate 8 into the spring according to springs of different lengths; a drive spring 9 is provided between the sliding plate 7 and the placement cylinder 3, a connecting plate 10 is fixed on the sliding plate 7, and a connecting groove 11 is opened on the placement cylinder 3 corresponding to the connecting plate 10. The drive spring 9 is placed in the connecting groove 11, with one end fixed to the connecting plate 10 and the other end fixed in the groove of the connecting groove 11. The drive spring 9 drives the connecting plate 10 to slide, thereby driving the sliding plate 7 to slide closer to the placement cylinder 3. Both sliding plates 7 have a wedge-shaped surface 12 at one end facing each other, and a drive plate 13 is slidably arranged inside the placement cylinder 3. The drive plate 13 slides towards or away from the sliding plate 7. Both ends of the drive plate 13 abut against the wedge-shaped surfaces 12 of the two sliding plates 7. When the drive plate 13 slides towards the sliding plate 7, it drives the sliding plates 7 to slide away from each other. When the drive plate 13 slides away from the sliding plate 7, the sliding plates 7 slide towards each other under the elastic force of the drive spring 9 until the wedge-shaped surfaces 12 abut against the drive plate 13. A drive bolt 14 is rotatably mounted on the turntable 2. The drive bolt 14 penetrates the turntable 2 and is inserted into the placement cylinder 3. One end of the drive bolt 14 inserted into the placement cylinder 3 is rotatably connected to the drive plate 13. Tightening the drive bolt 14 causes it to enter a placement cylinder... Inside the cylinder 3, the drive plate 13 is moved towards the sliding plate 7, causing the two sliding plates 7 to slide away from each other, and causing the corresponding two abutment plates 8 to slide away from each other. The drive bolt 14 is loosened, and the end of the drive bolt 14 inserted into the placement cylinder 3 moves away from the placement cylinder 3, causing the drive plate 13 to slide away from the sliding plate 7. Under the elastic force of the drive spring 9, the sliding plates 7 slide towards each other, causing the corresponding two abutment plates 8 to slide towards each other. The position of the abutment plate 8 is adjusted by tightening and loosening the drive bolt 14. At the same time, the drive bolt 14 can also assist in the installation and fixation of the placement cylinder 3 on the turntable 2.

[0035] Reference Figure 3 and Figure 4The abutment plate 8 has a groove 20 on the side facing the placement cylinder 3. The fixing member 4 is slidably and rotatably set in the groove 20. The fixing member 4 is rotatably embedded in the groove 20, thereby reducing the impact on the insertion of the spring into the abutment plate 8. After the spring is inserted into the abutment plate 8, the fixing member 4 is rotated to disengage from the groove 20 and the fixing member 4 is slidably moved so that the fixing member 4 abuts the spring against the inner wall of the placement hole 5 opened in the placement cylinder 3 to clamp and fix the spring. Both ends of the abutment plate 8 in the width direction have sliding grooves 21, which are connected to the groove 20. A sliding screw 22 slides in the sliding groove 21 and is fixed on the fixing member 4. The end of the sliding screw 22 away from the fixing member 4 passes through the sliding groove 21 and extends out of the abutment plate 8. The end of the sliding screw 22 extending out of the abutment plate 8 is threadedly connected to a sliding nut 23. Tightening the sliding nut 23 fixes the fixing member 4, and loosening the sliding nut 23 allows the sliding fixing member 4 to be rotated.

[0036] Reference Figure 1 and Figure 5 The machine body 1 is equipped with a dust collection device 17, which includes a dust collection hood 171 located near the grinding mechanism 6 on the machine body 1. A dust collection pipe 172 is installed on the dust collection hood 171. An air extraction device is installed at the end of the dust collection pipe 172 away from the dust collection hood 171. The dust collection hood 171, together with the dust collection pipe 172, can collect dust from the grinding area, reducing the probability of grinding debris accumulating in the machine body 1 and affecting subsequent grinding. The dust collection device 17 also includes a debris suction pipe 173, which is located on the machine body 1 at the point where the placement cylinder 3 enters the machine body 1. There are two debris suction pipes 173, which are respectively located at both ends of the length direction of the placement cylinder 3. The end of the debris suction pipe away from the machine body 1 is connected to the air extraction device. In this embodiment, the air extraction device is a blower. The debris suction pipe 173 is used to absorb impurities at the spring processing end, reducing the impact of impurities on subsequent grinding.

[0037] The implementation principle of this application embodiment is as follows: the spring is placed in the placement hole 5 and both ends of the spring extend out of the two ends of the placement cylinder 3. Then, according to the length of the spring, the drive bolt 14 is rotated to adjust the position of the abutment plate 8, and the abutment plate 8 is inserted into the spring. The sliding nut 23 is loosened and the fixing member 4 is rotated and slid to abut the spring against the inner wall of the placement cylinder 3. Then, the sliding nut 23 is tightened so that the fixing member 4 fixes the spring on the placement cylinder 3. The positions of the two sets of grinding mechanisms 6 are adjusted according to the length of the spring. Then, the placement cylinder 3 with the spring fixed is rotated and sent into the machine body 1 for grinding through the turntable 2. Before the spring enters the machine body 1, it passes through the suction pipe 173. The suction pipe 173 removes the debris adhering to the end of the spring to be ground. When the spring is being ground, the dust suction pipe 172 removes the debris generated by grinding. After the spring is ground, the turntable 2 drives the spring 9 to detach from the machine body 1. Then, the spring is taken out from the placement cylinder 3 and replaced with an unprocessed spring.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
