Description

A modular splicing marble measuring tool Technical Field

[0001] This utility model relates to the field of measuring tool technology, specifically a modular splicing marble measuring tool. Background Technology

[0002] Marble measuring tools are instruments made of natural or artificial marble as the base material, precision machined for measuring geometric quantities such as length, angle, and flatness. Due to their unique physical and chemical properties, they have wide applications in the field of precision measurement.

[0003] A search revealed a utility model patent with Chinese patent publication number CN220313102U, which discloses a granite V-shaped block, comprising: a work frame, a worktable fixedly installed on the top of the work frame, a movable groove opened on the top of the worktable, a bidirectional threaded rod A movably inserted into the inner wall of the movable groove, and movable blocks rotatably sleeved on the two outer threaded outer walls of the bidirectional threaded rod A, and V-shaped block bodies fixedly installed on the inner walls of the two movable blocks by screws.

[0004] Existing measuring tools are generally integrally molded. When a part of the measuring tool is damaged, the entire measuring tool often needs to be replaced because it is a whole structure. This not only wastes resources but also increases the cost of use. Therefore, a modular splicing marble measuring tool is proposed. Summary of the Invention

[0005] The purpose of this utility model is to provide a modular splicing marble measuring tool to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular splicing marble measuring tool, comprising a receiving frame, a V-shaped block one, and a V-shaped block two. Both V-shaped blocks one and two are slidably inserted into a groove inside the receiving frame. A splicing assembly is installed between V-shaped blocks one and two. The splicing assembly includes a plug rod, which is fixedly connected to the outer wall of one side of V-shaped block two. A slot adapted to the plug rod is opened inside V-shaped block one. A lead screw is threadedly connected inside the receiving frame, and a pressing block is rotatably connected to one end of the lead screw. The pressing block is slidably connected inside the receiving frame. Two limiting rods are slidably inserted inside the receiving frame, and both limiting rods are fixedly connected to the outside of the pressing block.

[0007] The two V-blocks can be used together. Even if one V-block is damaged, it can be replaced accordingly, which will not cause too much waste and will help save costs. Insert the external rod of V-block 2 into the internal slot of V-block 1. Since the rod is rectangular, it can keep V-block 1 and V-block 2 on the same horizontal plane when used with the slot. Then put them into the receiving frame and start rotating the screw by turning the knob. The extrusion block cannot rotate under the restriction of the two limit rods. The screw can drive the extrusion block to move closer to V-block 2. Under the extrusion of the extrusion block, the positions of V-block 1 and V-block 2 will be firmly restricted. At this time, it can be used.

[0008] As a further preferred embodiment of this technical solution, a limiting block is provided on the side of the receiving frame and the extrusion block that are close to each other, and a positioning groove adapted to the limiting block is provided on the outer wall of the side of the V-shaped block one and V-shaped block two that are far from each other.

[0009] As a further preferred embodiment of this technical solution, two barrier components are installed on the outside of the receiving frame, and the two barrier components are respectively located on the outer walls at both ends of the receiving frame.

[0010] As a further preferred embodiment of this technical solution, the barrier component includes two extension blocks fixedly connected to one end of the top outer wall of the receiving frame. The same sliding frame is fixedly connected to one end of the outer wall of the two extension blocks. The same mounting rod is slidably sleeved on the two sliding frames. The barrier block is slidably sleeved on the outside of the mounting rod. The upper half of the barrier block is stepped.

[0011] Pushing the barrier block causes the mounting rod to slide, and the mounting rod will move along the sliding frame closer to V-block one and extend to an appropriate degree. When V-block two is squeezed again, the groove formed by V-block one and V-block two will have a greater load-bearing capacity under the obstruction of the two barrier blocks, and ensure that the two are in a stable state. The barrier block can slide along the mounting rod, which can prevent it from affecting the splicing work.

[0012] As a further preferred embodiment of this technical solution, the thread helix angle of the external thread of the lead screw is smaller than the equivalent friction angle.

[0013] As a further preferred embodiment of this technical solution, the edge of the insertion rod near the V-shaped block is set as an arc edge.

[0014] As a further preferred embodiment of this technical solution, both V-shaped block one and V-shaped block two are made of marble.

[0015] This utility model provides a modular splicing marble measuring tool, which has the following beneficial effects:

[0016] (1) By setting up a splicing component, the two V-blocks can be spliced ​​together. Even if one V-block is damaged, it can be replaced accordingly, which will not cause too much waste and is conducive to saving costs. The external rod of the second V-block is inserted into the internal slot of the first V-block. Since the rod is rectangular, it can keep the first V-block and the second V-block on the same horizontal plane when it is in conjunction with the slot. Then, the two are placed inside the receiving frame. The screw is driven to start rotating by the knob. The extrusion block cannot rotate under the restriction of the two limit rods. The screw can drive the extrusion block to move closer to the second V-block. Under the extrusion of the extrusion block, the positions of the first V-block and the second V-block will be firmly restricted. At this time, it can be used.

[0017] (2) By setting up a barrier component, the present invention pushes the barrier block to drive the mounting rod to slide. The mounting rod will then move along the sliding frame to approach the V-block one and select an appropriate extension degree. When the V-block two is squeezed again, under the barrier of the two barrier blocks, the groove formed by the V-block one and the V-block two will have a greater load-bearing capacity and ensure that the two are stable enough. The barrier block can slide along the mounting rod, which can avoid affecting the splicing work. Attached Figure Description

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] This utility model provides a technical solution: As shown in Figures 1 and 2, in this embodiment, a modular splicing marble measuring tool includes a receiving frame 1, a V-shaped block 1 2, and a V-shaped block 2 3. The V-shaped block 1 2 and the V-shaped block 2 3 are slidably inserted into the groove inside the receiving frame 1. A splicing component 4 is installed between the V-shaped block 1 2 and the V-shaped block 2 3. The splicing component 4 includes an insert rod 405, which is fixedly connected to the outer wall of one side of the V-shaped block 2 3. The V-shaped block 1 2 has a slot 404 adapted to the insert rod 405. A lead rod 401 is threadedly connected inside the receiving frame 1. One end of the lead rod 401 is rotatably connected to a pressing block 403. The pressing block 403 is slidably connected inside the receiving frame 1. Two limiting rods 402 are slidably inserted inside the receiving frame 1, and both limiting rods 402 are fixedly connected to the outside of the pressing block 403.

[0025] A limiting block 408 is provided on the side of the receiving frame 1 and the extrusion block 403 that are close to each other. A positioning groove 407 adapted to the limiting block 408 is provided on the outer wall of the side of the V-shaped block 2 and V-shaped block 3 that are far from each other. With the cooperation of the limiting block 408 and the positioning groove 407, the position of V-shaped block 2 and V-shaped block 3 can be more stable.

[0026] Insert the external rod 405 of V-block 2 3 into the internal slot 404 of V-block 1 2. Since the rod 405 is rectangular, it can keep V-block 1 2 and V-block 2 3 on the same horizontal plane when used with the slot 404. Then place them into the receiving frame 1. Drive the screw 401 to start rotating by turning the knob. The pressing block 403 cannot rotate under the restriction of the two limit rods 402. The screw 401 can drive the pressing block 403 to move closer to V-block 2 3. Under the pressure of the pressing block 403, the positions of V-block 1 2 and V-block 2 3 will be firmly restricted. At this time, it can be used.

[0027] As shown in Figures 1 and 3, two barrier components 5 are installed on the outside of the receiving frame 1, and the two barrier components 5 are located at the outer walls of both ends of the receiving frame 1.

[0028] The barrier component 5 includes two extension blocks 501 fixedly connected to one end of the top outer wall of the receiving frame 1. The same sliding frame 502 is fixedly connected to one end of the outer wall of the two extension blocks 501. The same mounting rod 503 is slidably sleeved on the two sliding frames 502. A barrier block 504 is slidably sleeved on the outside of the mounting rod 503. The upper part of the barrier block 504 is stepped.

[0029] If the diameter of the object to be measured is large, it will not be stable when placed in the overall structure composed of V-block 1 2 and V-block 2 3. First, release the pressure on V-block 2 3, push the barrier block 504 to drive the mounting rod 503 to slide. The mounting rod 503 will then move along the sliding frame 502 closer to V-block 1 2 and select an appropriate extension degree. When V-block 2 3 is pressed again, under the obstruction of the two barrier blocks 504, the groove formed by V-block 1 2 and V-block 2 3 will have a greater load-bearing capacity and ensure that the two are in a stable state. The barrier block 504 can slide along the mounting rod 503, which can avoid affecting the splicing work.

[0030] As shown in Figure 1, the thread helix angle of the external thread of the lead screw 401 is less than the equivalent friction angle, giving it a self-locking property, thereby ensuring that the position of the extrusion block 403 connected to it will not change during use.

[0031] As shown in Figure 2, the edge of the insertion rod 405 near the V-block 2 is set as an arc edge 406, which makes the splicing process of the two more convenient and has a higher fault tolerance.

[0032] As shown in Figures 1 and 2, both V-block 1 (2) and V-block 2 (3) are made of marble. This material has a low coefficient of thermal expansion, is less affected by temperature changes, and can maintain long-term dimensional stability. It is also relatively soft and easy to process, enabling higher surface finish and dimensional accuracy.

[0033] This utility model provides a modular splicing marble measuring tool, the specific working principle of which is as follows:

[0034] When assembling the device, the external insertion rod 405 of V-block 2 3 is inserted into the internal slot 404 of V-block 1 2. Since the insertion rod 405 is rectangular, it can keep V-block 1 2 and V-block 2 3 on the same horizontal plane when used with the slot 404. Then, the two are placed inside the receiving frame 1. The screw 401 is driven to rotate by the knob. The pressing block 403 cannot rotate under the restriction of the two limit rods 402. The screw 401 can drive the pressing block 403 to move closer to V-block 2 3. Under the pressure of the pressing block 403, the positions of V-block 1 2 and V-block 2 3 will be firmly restricted. At this time, it can be used. If the measuring tool needs to be used like the patent with announcement number CN220313102U, a mounting block adapted to the driving component can be welded to the bottom wall of the receiving frame 1. If the diameter of the object to be measured is large, it will not be stable when placed in the overall structure composed of V-block 1 2 and V-block 2 3. First, release the pressure on V-block 2 3, push the barrier block 504 to drive the mounting rod 503 to slide. The mounting rod 503 will then move along the sliding frame 502 closer to V-block 1 2 and select an appropriate extension degree. When V-block 2 3 is pressed again, under the obstruction of the two barrier blocks 504, the groove formed by V-block 1 2 and V-block 2 3 will have a greater load-bearing capacity and ensure that the two are in a stable state. The barrier block 504 can slide along the mounting rod 503, which can avoid affecting the splicing work.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
