Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a spring end surface grinding device. Background Art

[0002] A spring is a mechanical part that uses elasticity to work. Parts made of elastic materials deform under the action of external force and return to their original shape after the external force is removed. They are also called "springs" and are generally made of spring steel. There are many types of springs. According to their shapes, there are mainly coil springs, scroll springs, leaf springs, special-shaped springs, etc. After the spring is produced and processed, there will be some defects on the end face. When the end face defects need to be processed, grinding equipment is needed. Grinding is a surface modification technology. It generally refers to a processing method that uses rough objects, sandpaper containing higher hardness particles, etc. to change the physical properties of the material surface through friction. The main purpose is to obtain a specific surface roughness.

[0003] After searching, a spring end face grinding machine with a publication number of CN212665638U specifically discloses a spring end face grinding machine, including a base, a hole on the right side of a fixing block connected to the left side of a spring fixing rod, an outer surface of the spring fixing rod fixedly connected to the inner side of an airbag, a hole on the top of the outer surface of the spring fixing rod connected to the inside of the airbag, and an outer surface of the airbag fits the inner wall of the spring. The utility model moves the motor together with the grinding disc forward by rotating the first handle, and then rotates the second handle to drive the spring fixing rod to move to the right. After the spring is inserted into the spring fixing rod, the end face of the spring to be polished is placed on the right and protrudes to the right, and then the air pump is turned on. The gas generated by the air pump passes through the bellows, the air guide tube, the fixing block and the spring fixing rod, and finally enters the airbag. After the airbag is inflated, it expands to fill the gap of the spring, completing the fixing of the spring, thereby reducing the wear of the outer surface of the spring caused by fixing the spring by clamping.

[0004] The grinding device proposed in the above patent cannot fix springs with different inner diameters. When encountering a spring with a larger or smaller inner diameter, a larger gap will occur between the spring and the spring fixing rod, resulting in poor spring stability, causing the spring to shake during the grinding process, affecting the grinding effect of the grinding device.

[0005] Therefore, it is necessary to invent a spring end surface grinding device to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a spring end surface grinding device to solve the problems raised in the above background technology.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a spring end surface grinding device, comprising a shell, a support rod is arranged at the upper end of the shell, damping reset rods are installed at both ends of the upper end of the support rod, a movable sleeve is arranged at the other end of the damping reset rod, a connecting rod is arranged at the upper end of the support rod, a screw rod passes through the upper end of the connecting rod, the lower end of the screw rod is connected to a limiting plate, and the outer wall of the movable sleeve is movably connected to a spring.

[0008] A shock-absorbing spring rod is fixedly installed at the lower end of the shell, and a base is fixedly installed at the lower end of the shock-absorbing spring rod.

[0009] A bottom groove is provided on the upper end surface of the shell, a collecting drawer is movably connected inside the bottom groove, and a grille is provided at the upper end of the bottom groove.

[0010] The collecting drawer is movably connected to the bottom groove, and the inner wall size of the bottom groove is consistent with the outer wall size of the collecting drawer.

[0011] An electric slide rail is arranged at the upper end of the grille, a slider is movably connected to the upper end of the electric slide rail, and a bracket is fixedly installed on the upper end of the slider.

[0012] A rotating shaft is connected to one side of the bracket, one end of the rotating shaft is movably connected to a driving motor, and the other end of the rotating shaft is connected to a grinding disc.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. Through the arrangement of the support rod, damping reset rod, movable sleeve, connecting rod, screw and limit plate, the arrangement of the support rod can play a supporting and fixing role for the spring during processing, and the damping reset rods arranged at the upper and lower ends of the support rod can drive the movable sleeve and the support rod to contract. When facing springs with different inner diameters, the movable sleeve can be adjusted to different positions to ensure that the outer side of the movable sleeve fits the inner side of the spring, so as to support the spring and prevent the spring end face from being poorly fixed during grinding, thereby affecting the grinding effect. The arrangement of the limit plate can further limit the spring on the support rod, improve the stability of the spring during processing, make the spring grinding more convenient, and will not cause the spring to shake;

[0015] 2. Through the setting of the bottom groove, the collection drawer and the grille, the cooperation between the bottom groove and the collection drawer can collect the waste chips generated during the spring grinding, preventing the waste chips from being scattered on the outer shell, causing inconvenience to the subsequent cleaning of the waste chips and affecting the processing environment. The setting of the collection drawer can play a role in unified recycling and processing of the collected waste chips, making the waste chip processing more convenient.

The setting of the shock-absorbing spring rod 2 can reduce the vibration generated during the processing of the shell 1, thereby improving the stability of the shell 1 when used.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a bottom groove 4 is provided on the upper end surface of the shell 1, and a collecting drawer 5 is movably connected inside the bottom groove 4. The collecting drawer 5 and the bottom groove 4 are movably connected. The inner wall size of the bottom groove 4 matches the outer wall size of the collecting drawer 5. The setting of the collecting drawer 5 can collect the waste generated when the end face of the spring 13 is polished, and prevent the waste from splashing, which makes subsequent cleaning inconvenient. A grille 6 is provided at the upper end of the bottom groove 4. The setting of the bottom groove 4 is convenient for the collection drawer 5 to be placed, and the collection drawer 5 is used in conjunction with the collection drawer 5.

[0027] like Figure 1 and Figure 3 As shown, an electric slide rail 14 is provided at the upper end of the grille 6, a slider 15 is movably connected to the upper end of the electric slide rail 14, a bracket 16 is fixedly installed on the upper end of the slider 15, and the cooperation between the electric slide rail 14 and the slider 15 can adjust the position of the grinding disc 19 according to the position of the end face of the spring 13.

During the sleeve setting process of the spring 13, the movable sleeve 9 arranged on the support rod 7 is squeezed, and during the compression process of the movable sleeve 9, it will shrink to the maximum bearing range of the inner diameter of the spring 13, thereby playing a supporting and fixing role for the spring 13, wherein the limit plate 12 is adjusted by the screw rod 11, so that the limit plate 12 limits and fixes the spring 13, so that when the spring 13 is fixed After it is set, turn on the switch of the electric slide 14, so that the electric slide 14 drives the bracket 16 to adjust the position. After the grinding disc 19 set on the bracket 16 is adjusted to a suitable position, turn off the switch of the electric slide 14, and then turn on the switch of the drive motor 18, so that the drive motor 18 drives the grinding disc 19 to rotate. During the rotation of the grinding disc 19, the end surface of the spring 13 is processed. After the spring 13 is processed, other springs 13 can be replaced for processing. When the device is not in use, the external power supply of the device can be cut off.
