Description

Technical Field

[0001] The utility model relates to the technical field of stone engraving machines, in particular to an anti-deviation structure of a stone engraving machine. Background Art

[0002] Stone carving mainly refers to various artworks and practical items carved from natural stones such as granite, marble, and wax cactus using techniques such as round carving, relief carving, openwork carving, and line carving. With the development of science and technology, stone carving is becoming more and more inseparable from stone engraving machines. During stone carving, due to the high-speed operation of the engraving machine, the stone will shake and affect the quality of the carving. Therefore, the stone engraving machines in the prior art will be equipped with corresponding anti-deviation structures to fix the stone to be carved.

[0003] Publication number "CN218462594U" provides an anti-deviation structure for a stone engraving machine, which fixes the stone through a combination of a base, a motor, a threaded rod, a movable column, a connecting block, a stabilizing plate, a movable groove, a slide groove and other structures, so that the stone will not shake or deviate during the engraving process, thereby improving the quality of the product, avoiding product damage, and reducing production costs.

[0004] However, the above technical solutions and the prior art have the following defects:

[0005] Although the anti-deviation structure of the stone engraving machine can fix the stone, the slide groove opened makes it easy for some dust or debris generated in the engraving process to fall and adhere to the annular side of the threaded rod. Once dust or debris adheres to the annular side of the threaded rod, it is easy for the moving column to get stuck during the movement. Since the stone itself has a certain weight, and since the stone engraving machine has no ability to lift the stone, after the stone is placed on the upper end surface of the base, it is rather laborious to adjust the forward and backward displacement once it needs to be done. Therefore, its practicality needs to be improved. Utility Model Content

[0006] The utility model aims to provide a stone engraving machine anti-deviation structure to solve the problems raised in the above background technology.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. After the stone plate to be processed is placed at the required position on the end surface of the processing table, by controlling the servo motors on the left and right sides to rotate forward, the servo motors on the left and right sides can drive the clamping plates on the left and right sides to move inward through the worm, worm gear, transmission screw and telescopic rod to clamp and fix the stone plate to be processed, so as to avoid the stone plate to be processed from deflecting during the engraving process. Similarly, when the servo motors on the left and right sides are controlled to rotate reversely, the clamping plates on the left and right sides can be moved outward so that the staff can take away the stone plate to be processed, and this structure will not cause jamming due to adhesion of dust or debris during use;

[0029] Positioning components 5 are symmetrically arranged on the left and right sides of the upper end surface of the processing table 1, and the positioning components 5 are used to clamp and fix the stone plate 3 to be processed placed on the upper end surface of the processing table 1 to prevent the stone plate 3 to be processed from shifting during the carving process. A lifting component 2 is arranged in the middle position inside the processing table 1, and the lifting component 2 is used to lift and guide the stone plate 3 to be processed, so that the stone plate 3 to be processed is more labor-saving during the process of taking and placing.

[0030] The positioning assembly 5 includes a clamping plate 51, a support seat 52, a servo motor 53, a telescopic rod 55, an internal threaded hole 56, a transmission screw 57, a worm 58 and a worm wheel 59. The support seat 52 is symmetrically installed on the left and right sides of the upper end surface of the processing table 1. The support seat 52 can support and limit the telescopic rod 55. The telescopic rod 55 is installed inside the support seat 52. The telescopic rod 55 is connected to the clamping plate 51 and the limit block 551 by welding. The telescopic rod 55 can support the clamping plate 51. The left end of the telescopic rod 55 is provided with a clamping plate 51. The clamping plate 51 is provided with two groups, and the two groups of clamping plates 51 have the same specifications. The two groups of clamping plates 51 have the same specifications.

An internal threaded hole 56 is opened inside the telescopic rod 55, and a transmission screw 57 is installed inside the internal threaded hole 56. The internal threaded hole 56 is meshed with the transmission screw 57. The internal threaded hole 56 facilitates the forward and reverse transmission screw 57 to drive the telescopic rod 55 to move left and right.

The inner wall of the clamping plate 51 is provided with anti-slip texture, and the anti-slip texture makes the inner wall of the clamping plate 51 more anti-slip.

[0032] Embodiment 2:

[0033] On the basis of Example 1, in this embodiment, by controlling the extension of the electric hydraulic push rod 24, the electric hydraulic push rod 24 can drive multiple guide wheels 21 to rise together through the lifting plate 22 to lift the stone slab 3 to be processed, so that the staff can adjust the forward and backward displacement or pick up and place the stone slab 3 to be processed more easily. When the electric hydraulic push rod 24 is controlled to retract, the electric hydraulic push rod 24 can drive multiple guide wheels 21 to descend to the limit groove 25 together through the lifting plate 22, so as to prevent the guide wheels 21 from affecting the stability of the stone slab 3 to be processed placed on the upper end surface of the processing table 1.

[0034] The lifting assembly 2 includes a guide wheel 21, a lifting plate 22 and an electric hydraulic push rod 24. The lifting plate 22 is installed on the upper side of the processing table 1. The front and rear length of the lifting plate 22 is the same as the front and rear length of the processing table 1. The lifting plate 22 can support the guide wheel 21. The electric hydraulic push rods 24 are symmetrically installed on the front and rear sides of the lower end of the lifting plate 22. Two groups of electric hydraulic push rods 24 are installed, and the specifications of the two groups of electric hydraulic push rods 24 are the same. The two groups of electric hydraulic push rods 24 are connected to the external control panel through wires. The electric hydraulic push rods 24 can drive the lifting plate 22 up and down when working. Movement, multiple guide wheels 21 are symmetrically installed on the left and right sides of the upper end surface of the lifting plate 22. The multiple guide wheels 21 have the same specifications. The guide wheels 21 are fixed casters.

The limiting groove 25 facilitates the lifting plate 22 to descend inside the processing table 1. An installation cavity 23 is provided in the middle position inside the processing table 1. The installation cavity 23 facilitates the installation of the electric hydraulic push rod 24 inside the processing table 1.

[0035] Working principle: The staff first controls the electric hydraulic push rod 24 to extend, so that the electric hydraulic push rod 24 drives the lifting plate 22 to move upward, and the lifting plate 22 drives the multiple guide wheels 21 to rise together, and rises until the height of the upper end of the guide wheel 21 is higher than the height of the upper end surface of the processing table 1. At this time, the stone plate 3 to be processed can be placed on the upper end of the multiple guide wheels 21 and pushed to the rear side. In this process, the multiple guide wheels 21 make the stone plate 3 to be processed more labor-saving in the process of moving backward. When the stone plate 3 to be processed moves backward to the desired position, the electric hydraulic push rod 24 can be controlled to retract, so that the lifting plate 22 drives the multiple guide wheels 21 to move backward. The plurality of guide wheels 21 are lowered into the limit grooves 25, and the height of the upper ends of the guide wheels 21 is lower than the height of the upper end surface of the processing table 1, so that the stone plate 3 to be processed can be placed on the upper end surface of the processing table 1; then the staff can respectively control the servo motors 53 on the left and right sides to rotate forward through the external servo motor 53 controller, so that the servo motors 53 on the left and right sides drive the worms 58 on the left and right sides to rotate forward together, and the forward-rotating worm 58 will drive the transmission screws 57 on the left and right sides to reverse through the worm gear 59, and then the transmission screw 57 drives the clamping plates 51 on the left and right sides to move inward through the telescopic rod 55 to clamp and fix the stone plate 3 to be processed (refer to Figure 2 or Figure 3 ), to avoid the deviation of the stone plate 3 to be processed during the processing by the stone engraving machine body 4, and then the stone plate 3 to be processed can be engraved with the help of the stone engraving machine body 4; when the stone plate 3 to be processed is processed, the servo motors 53 on the left and right sides are controlled to reverse, so that the worm 58 can drive the clamping plates 51 on the left and right sides to move outward through the worm gear 59, the transmission screw 57 and the telescopic rod 55, so as to release the clamping fixation of the stone plate 3 to be processed, and then the electric hydraulic push rod 24 is controlled to extend, so that the electric hydraulic push rod 24 lifts the stone plate 3 to be processed through the lifting plate 22 and the guide wheel 21, and the lifted stone plate 3 to be processed will be separated from the upper end surface of the processing table 1, and the staff can move the stone plate 3 to be processed to the rear side or move it to the front side to take it away.
