Description

Technical Field

[0001] The utility model relates to the technical field of spring processing, in particular to a novel 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 external forces and return to their original shape after the external force is removed. They are generally made of spring steel. There are many types of springs. According to their shapes, they mainly include helical springs, scroll springs, leaf springs, special-shaped springs, etc.

[0003] After mass production, springs usually need to have their ends ground. However, spring end grinding devices usually do not have a fixing mechanism that can be adjusted according to the diameter and length of the spring, which limits the scope of use of the device and makes the work efficiency relatively low. Utility Model Content

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] Reference Figure 1-3A novel spring end surface grinding device comprises a workbench 1, a grinding machine 2 installed on the workbench 1, and a positioning mechanism 5 and a driving assembly installed on the workbench 1. The positioning mechanism 5 comprises a limit seat 501, a placement slot plate 502, a threaded rod 503, a slide rail 504, a moving seat 505 and a connecting rod 506. The limit seat 501 is provided with a plurality of slots with gradually increasing diameters. The placement slot plates 502 are multiple and arranged one by one at the slots of the limit seat 501. The moving seat 505 is multiple and slides on the workbench 1 through the slide rail 504. The threaded rod 503 is rotatably installed on the moving seat 505 and is arranged corresponding to the placement slot plate 502. The multiple moving seats 505 can be connected in series through the connecting rod 506.

[0024] The driving assembly includes an electric push rod 4, a fixed block 6 and a connector 7. The electric push rod 4 slides along the guide rail 3 fixed on the workbench 1. The fixed block 6 is fixed at the output end of the electric push rod 4. The connector 7 can connect the handle 5051 at the end surface of the movable seat 505 and the fixed block 6; the grinder 2 is installed on the workbench 1, and a groove is opened on the workbench 1 to make room for the grinding plate of the grinder 2, so that after the spring is placed, the lower end of the grinding plate can be ground.

[0025] The curvature of the placement slot plate 502 matches the diameter of a group of slots on the corresponding limiting seat 501; multiple placement slot plates 502 and multiple slots on the limiting seat 501 facilitate the corresponding placement of springs of different sizes.

[0026] Embodiment 1: The center point of the notch of the limit seat 501 is on the same horizontal line as the center point of the corresponding set of threaded rods 503. The spring to be ground is selected from a suitable notch on the limit seat 501 according to its diameter and placed on a corresponding set of placement slot plates 502. Then, the electric push rod 4 can be moved on the guide rail 3 to move the output end of the electric push rod 4 to a corresponding set of moving seats 505, so that the fixed block 6 at the end of the electric push rod 4 is close to the handle 5051. The connector 7 can be inserted into the inner side of the handle 5051 and the middle of the fixed block 6 to facilitate connecting the handle 5051 and the fixed block 6 and removing the connector 7 to separate the handle 5051 and the fixed block 6. Then, the connector 7 is inserted to connect the fixed block 6 and the handle 5051. The threaded rod 503 is rotated to make its end contact with one end of the spring.

[0027] After the above operation is completed, the grinding machine 2 can be driven, and the electric push rod 4 can be driven to push the moving seat 505 to move along the slide rail 504, and then the threaded rod 503 can be controlled to push the spring to the limit seat 501, so that the end of the spring contacts the grinding machine 2, and the grinding process is performed on it. According to the different diameters of the spring, after adaptive placement, the spring processing can be automatically realized;

[0028] Embodiment 2: On the basis of the above-mentioned embodiment 1, the following operation can also be performed. A through hole is opened in the middle of the movable seat 505 for inserting the connecting rod 506 to connect multiple movable seats 505. When springs of multiple different diameters need to be smoothed, multiple groups of movable seats 505 are arranged neatly in advance, and then the connecting rod 506 is passed through the multiple groups of movable seats 505 to connect the multiple movable seats 505. Then, the electric push rod 4 is moved to the middle position of the guide rail 3, and the fixed block 6 at the end of the electric push rod 4 is connected to the handle 5051 on the group of movable seats 505 located in the middle. After the springs are placed one by one on the corresponding group of placement slot plates 502, the threaded rod 503 is rotated so that the corresponding threaded rod 503 is in contact with the corresponding spring end, thereby ensuring that when the springs have different diameters and lengths, they can still be synchronously pushed to the smoothing machine 2 for smoothing, saving manpower operation.

[0029] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
