Description

Technical Field

[0001] This utility model relates to the field of stone processing technology, specifically a positioning structure for stone processing. Background Technology

[0002] The stone processing begins with raw stone blocks, and involves processes such as cutting, grinding, polishing, and carving to ultimately produce smooth, flat, and textured finished stone that can be used for architectural decoration and daily life. Stone carving machines are high-precision processing equipment. In actual processing, it is necessary to position and process the workpiece to ensure that the starting position of the carving machine in the X and Y axis directions is accurate. If the positioning is off, it may lead to incorrect finished product dimensions or pattern offset, affecting subsequent installation and overall effect.

[0003] According to Chinese Utility Model Application No. CN202422065621.X, a stone surface pattern carving machine for stone processing is proposed. The utility model describes a stone surface pattern carving machine equipped with a conveying device. This device can quickly transport the stone slab to be carved to the carving position, greatly reducing the time spent on manual handling. Since stone slabs are usually heavy, manual handling is not only laborious but also poses safety risks. The moving table feeding component replaces manual handling through mechanization, reducing the physical burden on workers. A chute is provided at the upper end of the worktable, and rollers allow the conveyor table to move left and right along the chute, making stone slab handling more time-saving and labor-saving. A pull rod is provided for easy hand-pulling of the conveyor table. An insertion hole is provided on the first fixed plate; inserting a block and inserting it into the corresponding slot at the front end of the worktable can fix the conveyor table and prevent movement during carving.

[0004] This stone surface pattern carving machine for stone processing uses a conveying device to move the clamping device and the stone. The carving machine is divided into a carving area and a loading and unloading area. It not only occupies a large area, but also requires the operator to hold both sides of the stone with both hands and move the stone horizontally to the designated position on the top of the conveying device when loading and unloading. Since the stone is heavy, the loading and unloading operation is time-consuming and laborious, which affects the positioning efficiency. Therefore, a positioning structure for stone processing is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a positioning structure for stone processing, which has advantages such as easy positioning and solves the problem that the loading and unloading of heavy stone is time-consuming and labor-intensive, affecting positioning efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning structure for stone processing, including a positioning seat, a transverse positioning mechanism connected to the top of the positioning seat, a longitudinal positioning mechanism connected inside the positioning mechanism, and a pushing mechanism and a circular roller connected to the top of the positioning seat. The positioning mechanism includes two electric push rods, both of which are fixedly connected to the top of the positioning seat, and both of the output ends of the electric push rods are fixedly fitted with transverse clamping plates. The pushing mechanism includes a bin body, which is fixedly connected to the bottom of the positioning seat. A motor is fixedly installed on the outer wall of the bin body. The output end of the motor passes through the bin body and is fixedly installed with a first threaded rod. A first threaded sleeve is installed on the external thread of the first threaded rod. A moving rod that passes through and extends to the top of the first threaded sleeve is fixedly installed. A moving hole matching the moving rod is opened on the top of the positioning seat. A pushing plate is fixedly installed on the top of the moving rod.

[0007] Furthermore, the positioning seat has a concave cross-section, and an mounting plate is fixedly installed at the bottom of the positioning seat.

[0008] Furthermore, each of the two lateral clamping plates has a lateral moving block fixedly installed at its bottom, extending into the positioning seat, and the top of the positioning seat has a lateral moving groove that matches the lateral moving block.

[0009] Furthermore, the longitudinal positioning mechanism includes a second threaded sleeve, which is fixedly connected to the inner top wall of the transverse clamping plate. A second threaded rod is threadedly connected to the inside of the second threaded sleeve. The top of the second threaded rod passes through the transverse clamping plate and is fixedly mounted with a knob. The bottom of the second threaded rod is rotatably mounted with a longitudinal clamping plate, and the bottom of the longitudinal clamping plate is fixedly mounted with an anti-slip pad.

[0010] Furthermore, a longitudinal moving block extending into the interior of the transverse clamping plate is fixedly installed on the side wall of the longitudinal clamping plate, and a longitudinal moving groove matching the longitudinal moving block is provided on the inner side wall of the transverse clamping plate.

[0011] Furthermore, the first threaded rod is rotatably connected to the inner wall of the chamber via a first bearing, and the bottom of the second threaded rod is rotatably connected to the longitudinal clamping plate via a second bearing.

[0012] Furthermore, the top of the positioning seat is provided with a groove, and there are multiple grooves and multiple rollers. The multiple grooves are evenly and equidistantly distributed on both sides of the moving hole. The multiple rollers are rotatably connected to the inner sidewalls of the multiple grooves through a third bearing. The tops of the multiple rollers are flush with each other, higher than the top of the positioning seat, and lower than the bottom of the transverse clamping plate and the bottom of the pusher plate.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects: This positioning structure for stone processing, consisting of a positioning seat, a transverse positioning mechanism, a longitudinal positioning mechanism, a pushing mechanism, and a circular roller, first places the stone on the top edge of the positioning seat. Then, the stone is pushed so that one side of the stone aligns with the pushing mechanism, causing the circular roller to rotate and reducing friction. Next, the transverse positioning mechanism positions the two sides of the stone, and finally, the longitudinal positioning mechanism positions the top of the stone. After processing, the top of the stone is released from positioning using the longitudinal positioning mechanism, and the two sides are released from positioning using the transverse positioning mechanism. Then, the pushing mechanism moves the stone to the top edge of the positioning seat, where the circular roller rotates again, reducing friction. Finally, the stone is unloaded by holding both sides with both hands. This design not only occupies less space but also saves time and effort in loading and unloading, improving positioning efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3The positioning structure for stone processing in this embodiment includes a positioning seat 1 with a U-shaped cross section. A transverse positioning mechanism 2 is connected to the top of the positioning seat 1. The stone is placed in the recess of the positioning seat 1. The transverse positioning mechanism 2 is located in the protrusion of the positioning seat 1. A longitudinal positioning mechanism 3 is connected inside the positioning mechanism 2. A pushing mechanism 4 and a roller 5 are connected to the top of the positioning seat 1. Mounting plates 6 with mounting holes are fixedly installed at the four corners of the bottom of the positioning seat 1.

[0018] Specifically, the positioning seat 1 is installed at the designated position on the engraving machine using bolts and mounting plate 6. First, the stone is placed on the top edge of the positioning seat 1, and then the stone is pushed so that one side of the stone is in contact with the pushing mechanism 4. The stone drives the roller 5 to rotate, reducing some friction. Then, the transverse positioning mechanism 2 is used to position the two sides of the stone, and finally, the longitudinal positioning mechanism 3 is used to position the top of the stone. After the engraving machine finishes engraving the top middle position of the stone, the longitudinal positioning mechanism 3 is used to release the top of the stone, and then the transverse positioning mechanism 2 is used to release the two sides of the stone. Then, the pushing mechanism 4 is used to move the stone to the top edge of the positioning seat 1, and the stone drives the roller 5 to rotate, reducing some friction. Finally, the stone is unloaded by holding both sides with both hands. This method not only occupies less area, but also saves time and effort in loading and unloading, improving positioning efficiency.

[0019] In this embodiment, the positioning mechanism 2 includes two electric push rods 21, both of which are fixedly connected to the top of the positioning seat 1. The output ends of the two electric push rods 21 are fixedly installed with transverse clamping plates 22. The bottom of the two transverse clamping plates 22 is fixedly installed with three transverse moving blocks extending into the positioning seat 1. The top of the positioning seat 1 is provided with transverse moving slots that match the transverse moving blocks.

[0020] Specifically, by activating the two electric push rods 21, the two electric push rods 21 drive the two transverse clamping plates 22 to move relative to each other, and the inner sidewalls of the two transverse clamping plates 22 respectively position the two sides of the stone.

[0021] In this embodiment, the longitudinal positioning mechanism 3 includes a second threaded sleeve 31, which is fixedly connected to the inner top wall of the transverse clamping plate 22. A second threaded rod 32 is threadedly connected to the inside of the second threaded sleeve 31. The top of the second threaded rod 32 passes through the transverse clamping plate 22 and is fixedly mounted with a knob 33. The bottom of the second threaded rod 32 is rotatably mounted with a longitudinal clamping plate 34 via a second bearing. A longitudinal moving block extending into the transverse clamping plate 22 is fixedly mounted on the side wall of the longitudinal clamping plate 34. A longitudinal moving groove matching the longitudinal moving block is opened on the inner side wall of the transverse clamping plate 22. In another embodiment, two limiting rods that pass through and extend above the transverse clamping plate 22 are fixedly mounted on the top of the longitudinal clamping plate 34. A limiting plate is fixedly mounted on the top of each of the two limiting rods. A rubber anti-slip pad 35 is fixedly mounted on the bottom of the longitudinal clamping plate 34.

[0022] Specifically, by rotating the knob 33, the knob 33 drives the second threaded rod 32 to rotate inside the second threaded sleeve 31. The second threaded sleeve 31 drives the longitudinal clamping plate 34 and the anti-slip pad 35 to move downwards, and the anti-slip pad 35 positions the top of the stone.

[0023] In this embodiment, the pushing mechanism 4 includes a bin body 41, which is fixedly connected to the bottom of the positioning seat 1. A motor 42 is fixedly installed on the outer wall of the bin body 41. The output end of the motor 42 passes through the bin body 41 and is fixedly installed with a first threaded rod 43. The first threaded rod 43 is rotatably connected to the inner wall of the bin body 41 through a first bearing. A first threaded sleeve 44 is installed on the outer thread of the first threaded rod 43. A moving rod 45 that passes through and extends above the positioning seat 1 is fixedly installed on the top of the first threaded sleeve 44. A moving hole matching the moving rod 45 is opened on the top of the positioning seat 1. A pushing plate 46 is fixedly installed on the top of the moving rod 45. The side wall of the pushing plate 46 is flush with the inner side wall of the two transverse clamping plates 22.

[0024] Specifically, by turning on the motor 42, the motor 42 drives the first threaded rod 43 to rotate, and the first threaded rod 43 drives the first threaded sleeve 44, the moving rod 45, the pusher plate 46 and the stone to move in a straight line.

[0025] In this embodiment, the top of the positioning seat 1 is provided with a groove. The number of grooves and the number of rollers 5 are both sixteen. The number of grooves and the number of rollers 5 can also be set according to the actual use. The sixteen grooves are evenly distributed on both sides of the moving hole, with eight on each side. The sixteen rollers 5 are rotatably connected to the inner sidewall of the sixteen grooves through the third bearing. The tops of the sixteen rollers 5 are flush with each other and higher than the top of the positioning seat 1, but lower than the bottom of the transverse clamping plate 22 and the bottom of the pusher plate 46.

[0026] Specifically, when the stone moves horizontally on the top of the positioning seat 1, the stone drives the roller 5 to rotate, reducing some of the friction.

[0027] The working principle of the above embodiments is as follows: The positioning seat 1 is installed in the designated position on the engraving machine using bolts and mounting plate 6. The operator first places the stone on the top edge of the positioning seat 1, then pushes the stone so that the side wall of the pusher plate 46 and the inner side wall of the two transverse clamping plates 22 are in contact with one side of the stone. The stone drives the roller 5 to rotate, reducing some friction. Then, the two electric push rods 21 are activated, causing the two transverse clamping plates 22 to move relative to each other. The inner side walls of the two transverse clamping plates 22 position the two sides of the stone respectively. Finally, the two knobs 33 are rotated, causing the two second threaded rods 32 to rotate inside the two second threaded sleeves 31 respectively. The two second threaded sleeves 31 respectively drive the two longitudinal clamping plates 34 and the two anti-slip pads 35 to move downwards. The two anti-slip pads 35 position the top of the stone. After the engraving machine finishes carving the top center of the stone, the two knobs 33 are rotated again, causing the two second threaded rods 32 to rotate inside the two second threaded sleeves 31 respectively. The inside of sleeve 31 rotates, and the two second threaded sleeves 31 drive the two longitudinal clamping plates 34 and the two anti-slip pads 35 to move upward respectively. The two anti-slip pads 35 release the positioning of the top of the stone. Then, the two electric push rods 21 are turned on, and the two electric push rods 21 drive the two transverse clamping plates 22 to move in opposite directions. The inner sidewalls of the two transverse clamping plates 22 release the positioning of the two sides of the stone respectively, so that the inner sidewalls of the two transverse clamping plates 22 form a small gap with the two sides of the stone. Then, the motor 42 is turned on, and the motor 42 drives the first threaded rod 43 to rotate. The first threaded rod 43 drives the first threaded sleeve 44, the moving rod 45, the pusher plate 46 and the stone to move in a straight line. The two transverse clamping plates 22 guide the movement direction of the stone until the stone moves to the top edge of the positioning seat 1. The stone drives the roller 5 to rotate, reducing some of the friction. Finally, the stone is unloaded by holding both sides with both hands. This not only occupies less area, but also saves time and effort in loading and unloading, improving positioning efficiency.
