Description

Technical Field

[0001] The utility model relates to the technical field of precision detection equipment for mechanically processed parts, in particular to a detection table for a roundness detection device. Background Art

[0002] The contents of this section merely provide background information related to the present invention and may not constitute prior art.

[0003] At present, the domestic manufacturing industry is developing rapidly, and the quality requirements for products are getting higher and higher. In order to improve the quality requirements of products, the accuracy requirements for workpieces are also getting higher and higher. As an important part of the workpiece accuracy measurement standard, cylindricity is a key indicator of workpiece accuracy. Therefore, roundness meters are usually used in enterprises to detect the roundness or cylindricity of workpieces.

[0004] In the process of inspecting workpieces, manual loading and unloading of workpieces has certain limitations, especially when facing a large amount of inspection. In order to reduce the work pressure of staff and the labor costs of enterprises, using machines to replace manual loading and unloading of workpieces has become the current choice for most people.

[0005] However, in actual use, since the inspection of workpieces is carried out one by one, the workpieces to be inspected and the workpieces that have been inspected need to be placed separately to avoid confusion and increase the time and labor costs of repeated inspections. Therefore, it is usually necessary to set up an area to be inspected and an inspected area on both sides of the inspection table. After a batch of workpieces has been inspected, the workpieces in the area to be inspected and the inspected area are uniformly classified and stored, which brings a certain labor burden to the staff. Summary of the invention

[0006] In order to solve the above technical problems, the purpose of the utility model is to provide a testing table for a roundness detection device, which can facilitate workers to store workpieces and reduce the labor burden of the workers.

[0007] The utility model provides a testing table for a roundness testing device, which adopts the following technical scheme:

[0008] A detection table for a roundness detection device comprises a detection table, and mounting plates are arranged on both side walls of the detection table, the mounting plates are detachably connected to the detection table, wherein an area to be inspected is arranged on one side of the mounting plate, and an inspected area is arranged on the other side of the mounting plate, and a limiting member is arranged on the mounting plate, and the limiting member is used to limit the position of the mounting plate on the detection table.

[0009] By adopting the above technical scheme, in actual use, the workpieces to be inspected are placed in the to-be-inspected area, and the workpieces that have completed the inspection are placed in the inspected area, so as to realize the classification and storage of the workpieces, avoid confusion between the workpieces that have completed the inspection and the workpieces that have not been inspected, reduce the labor burden of the staff, and improve the subsequent work efficiency. When it is necessary to take the workpiece that has completed the inspection, it is only necessary to release the limit of the position of the mounting plate on the inspection table by the limit piece, and then the mounting plate can be removed from the inspection table, thereby realizing the taking of all the inspected workpieces, further facilitating the operation, improving work efficiency, and reducing the labor burden.

[0010] In some possible embodiments, a mounting groove is opened in a horizontal direction on the side wall of the detection table, one side of the mounting groove is opened, a mounting block is slidably arranged in the mounting groove, the mounting block is fixedly connected to the side wall of the mounting plate, and the limiting member is arranged on the mounting block, and the limiting member is used to limit the position of the mounting block in the mounting groove.

[0011] By adopting the above technical solution, when the mounting plate is installed on the testing table, as the mounting plate moves, the mounting block slides in the mounting groove, and the side wall of the mounting block abuts against the inner wall of the mounting groove, which can provide a certain supporting effect on the mounting plate while also guiding the movement of the mounting plate on the side wall of the testing table, making it easier for the staff to install the mounting plate on the testing table.

[0012] In some possible embodiments, the limit member is configured as a limit rod, and the limit member is arranged on the side wall of the mounting block close to the inner wall of the mounting groove.

A limit protrusion is provided on the mounting rod, and two limit protrusions are provided. The two limit protrusions are arranged in a one-to-one correspondence with the two limit members, and the side walls of the two limit protrusions close to each other are used to abut against the two limit members to limit the deflection angle of the limit members.

[0017] By adopting the above technical solution, when driving the mounting block to slide into the mounting groove, since the limiting piece is arranged at the end of the mounting block, the roller on the limiting piece first abuts against the notch of the sliding groove. Since there are two limiting pieces, there are also two corresponding rollers. The two limiting pieces are symmetrically arranged one above and one below, which guides and supports the mounting block, further facilitating the staff to drive the mounting block to slide into the mounting groove. At the same time, by providing the limiting protrusion, the deflection angle of the limiting piece can be limited, thereby improving the reliability of the device during actual use.

DETAILED DESCRIPTION

[0038] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0039] The following reference Figures 1 to 7 The utility model is described in further detail.

[0040] Reference Figure 1 A detection table for a roundness detection device includes a detection table 1, on which a three-jaw chuck 6 is arranged. A workpiece 16 is clamped by the three-jaw chuck 6, and then the cylindricality of the workpiece 16 can be detected by a roundness meter (not shown in the figure). Mounting plates 11 are arranged on both side walls of the detection table 1, and the mounting plates 11 are detachably connected to the detection table 1, wherein a to-be-detected area 12 is arranged on one side of the mounting plate 11, and a detected area 13 is arranged on the other side of the mounting plate 11.

[0041] During actual use, the workpiece 16 to be inspected is placed in the inspected area 12, and the workpiece 16 that has completed the inspection is placed in the inspected area 13, so as to achieve classified storage of the workpiece 16, avoid confusion between the workpiece 16 that has completed the inspection and the workpiece 16 that has not been inspected, reduce the labor burden of the staff, and improve the subsequent work efficiency.

[0042] Among them, refer to Figure 1 A receiving cavity 14 is provided at the top of the mounting plate 11 , and receiving holes 15 for placing workpieces 16 are provided at the bottom of the receiving cavity 14 , and a workpiece 16 is placed in each receiving hole 15 .

[0043] The mounting plates 11 on both sides of the testing platform 1 have the same structure. One side is artificially divided into a waiting area 12 for placing workpieces 16 to be tested, and the other side is divided into an inspected area 13 for placing workpieces 16 that have been tested.

[0044] Reference Figure 2-5 , a limiting member 2 is provided on the mounting plate 11, specifically as follows Figure 5 As shown, the position limiter 2 is used to limit the position of the mounting plate 11 on the testing platform 1. When the workpiece 16 that has been tested needs to be taken, it is only necessary to release the position limiter 2 on the mounting plate 11 on the testing platform 1, and then the mounting plate 11 can be removed from the testing platform 1, thereby realizing the taking of all the tested workpieces 16, which further facilitates the operation, improves the work efficiency, and reduces the labor burden.

[0045] Reference Figure 2 , 3, a mounting groove 3 is provided in the horizontal direction on the side wall of the testing platform 1, and the mounting groove 3 is provided on both sides of the testing platform 1, and one side of the mounting groove 3 is provided with an opening, and a mounting block 31 is slidably provided in the mounting groove 3, and the mounting block 31 is fixedly connected to the side wall of the mounting plate 11, and a limiter 2 is provided on the mounting block 31, and the limiter 2 is used to limit the position of the mounting block 31 in the mounting groove 3. When the mounting plate 11 is installed on the testing platform 1, as the mounting plate 11 moves, the mounting block 31 slides in the mounting groove 3, and the side wall of the mounting block 31 abuts against the inner wall of the mounting groove 3, which can provide a certain support effect for the mounting plate 11, and also guide the movement of the mounting plate 11 on the side wall of the testing platform 1, so that the staff can install the mounting plate 11 on the testing platform 1.

[0046] Reference Figure 2-5 As an embodiment of the present invention, the limiter 2 is configured as a limiter rod, the limiter 2 is disposed on the side wall of the mounting block 31 close to the inner wall of the mounting groove 3, a sliding groove 4 for sliding the limiter 2 is provided on the inner wall of the mounting groove 3 along the length direction of the mounting groove 3, and one side of the sliding groove 4 is provided with an opening. Specifically, the sliding groove 4 is connected to the mounting groove 3, the sliding groove 4 and the mounting groove 3 form a T-shaped groove as a whole, the mounting block 31 is slidably disposed in the mounting groove 3, the limiter 2 is disposed at the end of the mounting block 31, a sliding block 41 is fixedly disposed on the side wall of the mounting block 31 close to the sliding groove 4, the shape and size of the sliding block 41 are adapted to the sliding groove 4, one end of the sliding block 41 is arranged flush with the mounting block 31, and the overall length of the sliding block 41 is shorter than that of the mounting block 31, and the stability of the mounting block 31 and the mounting plate 11 during movement can be further improved by providing the sliding block 41.

[0047] Reference Figure 4 , 5 A slot 42 for the end of the limiting member 2 to be inserted into is provided on the inner wall of the sliding groove 4, and a first elastic member 43 is provided on the mounting block 31, and the first elastic member 43 is used to drive the limiting member 2 to move in a direction away from the mounting block 31.

[0048] As the mounting block 31 moves in the mounting groove 3, the mounting block 31 drives the limiting member 2 to move in the mounting groove 3. At this time, under the action of the first elastic member 43, the end of the limiting member 2 away from the mounting block 31 abuts against the inner wall of the sliding groove 4. When the limiting member 2 moves to the position of the card slot 42, the limiting member 2 is carded into the card slot 42 under the action of the first elastic member 43, thereby limiting the position of the mounting block 31 in the mounting groove 3, and further limiting the position of the mounting plate 11 on the side wall of the detection table 1.

[0049] Among them, refer to Figure 4 , 5The limiting member 2 is arranged at the end of the mounting block 31, and a mounting shaft 44 is rotatably arranged on the side wall of the mounting block 31 away from the mounting plate 11. As an embodiment of the utility model, the first elastic member 43 is arranged as a torsion spring, and the first elastic member 43 is sleeved on the mounting shaft 44. One end of the first elastic member 43 is fixedly connected to the mounting shaft 44, and the other end is fixedly connected to the side wall of the mounting block 31. The mounting shaft 44 is fixedly connected to one end of the limiting member 2, and a roller 45 is rotatably arranged at the end of the limiting member 2 away from the mounting shaft 44, and the roller 45 is parallel to the rotation axis of the mounting shaft 44.

[0050] During the movement of the limit member 2 in the sliding groove 4, the roller 45 effectively reduces the friction between the end of the limit member 2 and the inner wall of the sliding groove 4, which facilitates the movement of the limit member 2 in the sliding groove 4 and the movement of the mounting block 31 in the mounting groove 3. By setting the roller 45, it is also convenient for the staff to drive the limit member 2 to disengage from the slot 42 by applying external force, thereby improving the practicability of the device during actual use.

[0051] As an implementation mode of the present utility model, refer to Figure 5 The slot 42 is set to be an arc-shaped groove, and the diameter of the slot 42 is larger than the diameter of the roller 45. In the actual installation and disassembly process, the limit member 2 is deflected under the action of the first elastic member 43, thereby driving the roller 45 to be stuck in the slot 42. Without applying external force, since the slot 42 is an arc-shaped groove and the first elastic member 43 acts on the limit member 2, the roller 45 can always be kept in the position in the slot 42. When the staff applies an external force to the mounting plate 11 to drive the mounting plate 11 to move in the direction away from the detection platform 1, and then drives the mounting block 31 to move in the mounting slot 3, the mounting block 31 can drive the roller 45 to disengage from the slot 42, thereby realizing the disassembly of the mounting block 31 and the mounting plate 11. The operation is simple and convenient, and it has good practicality.

[0052] Reference Figure 3 , 5 There are two limit members 2, which are symmetrically arranged on the same side of the mounting rod along the length direction of the mounting block 31. A limit protrusion 46 is arranged on the mounting rod. There are two limit protrusions 46, which are arranged one by one with the two limit members 2. The side walls of the two limit protrusions 46 close to each other are used to abut against the two limit members 2 to limit the deflection angle of the limit members 2.

[0053] In the actual installation process, when the mounting block 31 does not enter the mounting groove 3, the side wall of the limiter 2 abuts against the limiter protrusion 46, thereby limiting the deflection angle of the limiter 2 and limiting the linear distance between the axes of the two rollers 45. Furthermore, assuming that the diameter of the roller 45 is d and the height of the mounting block 31 is h, when the mounting block 31 does not enter the mounting groove 3, the linear distance between the axes of the two rollers 45 is L, that is, h<L<d+h. In the process of driving the mounting block 31 into the mounting groove 3, the end of the mounting block 31 first enters the mounting groove 3, thereby driving the roller 45 to contact the notch of the sliding groove 4. With the further movement of the mounting block 31, the two rollers 45 are deflected toward each other under the squeezing of the notch of the sliding groove 4, thereby making the two rollers 45 enter the sliding groove 4. Afterwards, with the movement of the mounting block 31, the sliding block 41 also slides into the sliding groove 4 until the roller 45 is stuck in the slot 42, thereby limiting the position of the mounting block 31 in the mounting groove 3. Since h<L<d+h, it can ensure that the roller 45 can smoothly enter the sliding groove 4 to avoid being stuck.

[0054] Reference Figure 6 , 7 A hinge seat 17 is installed on the side wall of the detection platform 1, and a support rod 5 is rotatably installed on the hinge seat 17. A support portion 51 is slidably provided at one end of the support rod 5 away from the detection platform 1. The support portion 51 is slidably provided along the length direction of the support rod 5. A support groove 52 for the support portion 51 to be inserted is provided at the bottom of the mounting plate 11. A second elastic member 53 is provided on the support rod 5. The second elastic member 53 is used to drive the support portion 51 to move in a direction away from the support rod 5. A fixing member 54 is provided on the support rod 5. The fixing member 54 is used to limit the position of the support portion 51 on the support rod 5. By supporting the bottom of the mounting plate 11 by the support rod 5, the stability of the mounting plate 11 during the actual detection process can be further improved, and the practicality and reliability of the overall device can be further improved.

[0055] Among them, refer to Figure 7 A strip groove 55 is slidably provided on the support rod 5 along the length direction of the support rod 5, a strip block 56 is slidably provided in the strip groove 55, one end of the strip block 56 is fixedly connected to the support portion 51, a second elastic member 53 is provided in the strip groove 55, the second elastic member 53 is used to drive the strip block 56 to move in the strip groove 55, and the fixing member 54 is used to limit the position of the strip block 56 in the strip groove 55.

[0056] As an implementation mode of the present utility model, refer to Figure 7The strip groove 55 is set as a T-shaped groove, and the strip block 56 is set as a T-shaped block adapted to the strip groove 55; as another possible implementation manner of the utility model, the strip groove 55 can also be set as a dovetail groove, in which case the strip block 56 is set as a dovetail block adapted to the strip groove 55.

[0057] Reference Figure 7 The second elastic member 53 is configured as a compression spring. The second elastic member 53 is disposed in the strip groove 55 . One end of the second elastic member 53 abuts against the side wall of the strip block 56 , and the other end abuts against the inner wall of the strip groove 55 .

[0058] Reference Figure 7 As an embodiment of the present invention, the fixing member 54 is configured as a fixing bolt, a mounting hole 57 is provided on the side wall of the support rod 5, the mounting hole 57 is communicated with the strip groove 55, and a fixing hole 58 for threaded connection of the fixing bolt is provided on the side wall of the strip block 56. Since there is one support groove 52, there is only one corresponding mounting hole 57. When the support portion 51 is located in the support groove 52, the mounting hole 57 coincides with the fixing hole 58. At this time, the position of the strip block 56 in the strip groove 55 can be limited by the fixing bolt.

[0059] As an embodiment of the present invention, a ball bearing (not shown in the figure) is embedded in the end of the support portion 51 away from the support rod 5, and the ball bearing is used to roll with the bottom of the mounting plate 11. The ball bearing can effectively reduce the friction between the support portion 51 and the bottom of the mounting plate 11, making it convenient for the staff to drive the support portion 51 to move, thereby improving the practicality of the device.
