Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to a workbench for dimensional inspection of refractory bricks. Background Technology

[0002] In the production process of refractory bricks, dimensional inspection is a crucial step, directly affecting the quality of refractory bricklaying and the production safety of steel plants. Therefore, comprehensive dimensional inspection of refractory materials is of great significance. Typically, in refractory material manufacturing enterprises, for both stamping and static pressing forming methods, controlling the dimensions in the non-forming direction is relatively simple, while controlling the dimensions in the forming direction is more difficult. Furthermore, the thickness of different products varies. This necessitates a dimensional inspection device that can adjust the inspection dimensions and is simple and easy to operate, achieving the goal of high-efficiency inspection of the product's thickness direction. Utility Model Content

[0003] The main objective of this invention is to provide a workbench for measuring the dimensions of refractory bricks, so as to meet the requirements of adjustable measuring dimensions, simple operation and high efficiency mentioned in the background art.

[0004] This utility model achieves the above-mentioned objective through the following technical solution: a dimensional inspection workbench for refractory bricks, comprising a base plate and a positive dimension inspection mechanism and a negative dimension inspection mechanism disposed on the base plate. Both the positive dimension inspection mechanism and the negative dimension inspection mechanism include two sleeves vertically disposed on the base plate. A vertical rod is vertically connected to each of the two sleeves. The vertical rod is provided with a scale line along its length direction. A limiting rod is connected between the top ends of the two vertical rods. An adjustment mechanism for controlling the extension length of the vertical rod is connected between the vertical rod and the sleeve. The height of the limiting rod of the positive dimension inspection mechanism is higher than the height of the limiting rod of the negative dimension inspection mechanism.

[0005] Preferably, the adjusting mechanism includes a threaded rod coaxially disposed within the sleeve. The vertical rod has an inner cavity and an opening communicating with the inner cavity on its lower end face. A turntable is coaxially rotatable at the opening. A bushing is coaxially disposed on the upper end face of the turntable. A threaded hole matching the threaded rod is provided at the center of the turntable. The threaded rod passes through the threaded hole and extends into the bushing. A toothed ring is provided at the top of the outer periphery of the bushing. A horizontal sliding groove communicating with the inner cavity is provided at the top of the outer periphery of the vertical rod. A slider is connected in the sliding groove. One end of the slider extending into the inner cavity is provided with a limiting tooth that meshes with the toothed ring. The other end of the slider is connected to a push-pull block. A spring is sleeved on the slider. The two ends of the spring are respectively connected to the circumference of the vertical rod and the side of the push-pull block. The spring is in a stretched state.

[0006] Preferably, the substrate is a stainless steel plate.

[0007] Preferably, the portion of the slider located within the inner cavity is provided with an anti-detachment block.

[0008] The beneficial effects of this utility model are as follows: the maximum and minimum dimensions of the refractory bricks are detected by the positive dimension detection mechanism and the negative dimension detection mechanism, respectively. The refractory bricks are pushed in from the positive dimension detection mechanism side. Refractory bricks that can pass through the limiting rod of the positive dimension detection mechanism but cannot pass through the limiting rod of the negative dimension detection mechanism are qualified products. The workbench is simple to operate, requiring no manual measurement, which improves the detection efficiency. Moreover, the dimensions of the refractory bricks can be detected without the need for electronic measuring equipment, saving equipment costs. The height of the limiting rods can be adjusted by the adjustment mechanism to accommodate products of different specifications, making it highly practical. Attached Figure Description

[0013] The present invention will be further described in detail below with reference to specific embodiments.

[0014] Example:

[0015] like Figure 1 and Figure 2 As shown, this utility model discloses a dimensional inspection workbench for refractory bricks, comprising a base plate 1 and a positive dimension inspection mechanism and a negative dimension inspection mechanism disposed on the base plate 1. Both the positive dimension inspection mechanism and the negative dimension inspection mechanism include two sleeves 2 vertically disposed on the base plate 1. A vertical rod 3 is vertically connected to each of the two sleeves 2. The vertical rod 3 is provided with a scale line along its length direction. A limiting rod 4 is connected between the top ends of the two vertical rods 3. An adjustment mechanism for controlling the extension length of the vertical rod 3 is connected between the vertical rod 3 and the sleeves 2. The height of the limiting rod 4 of the positive dimension inspection mechanism is higher than the height of the limiting rod 4 of the negative dimension inspection mechanism.

[0016] The adjusting mechanism includes a threaded rod 5 coaxially disposed within the sleeve 2. The vertical rod 3 has an inner cavity and an opening on its lower end face that communicates with the inner cavity. A turntable 6 is coaxially rotatable at the opening. A bushing 7 is coaxially disposed on the upper end face of the turntable 6. A threaded hole matching the threaded rod 5 is provided at the center of the turntable 6. The threaded rod 5 passes through the threaded hole and extends into the bushing 7. A toothed ring 8 is provided at the top of the outer periphery of the bushing 7. A horizontal sliding groove 9 communicating with the inner cavity is provided at the top of the outer periphery of the vertical rod 3. A slider 10 is connected in the sliding groove 9. One end of the slider 10 extending into the inner cavity is provided with a limiting tooth 12 that meshes with the toothed ring 8. The other end of the slider 10 is connected to a push-pull block 13. A spring 11 is sleeved on the slider 10. The two ends of the spring 11 are respectively connected to the circumference of the vertical rod 3 and the side of the push-pull block 13. The spring 11 is in a stretched state.

[0017] The substrate 1 is a stainless steel plate.

[0018] The portion of the slider 10 located within the inner cavity is provided with an anti-detachment block 14.

[0019] The positive dimension detection mechanism is used to detect the maximum size of the refractory brick, and the negative dimension detection mechanism is used to detect the minimum size of the refractory brick. The refractory brick is pushed in from one side of the positive dimension detection mechanism. If the refractory brick can pass through the limiting rod 4 of the positive dimension detection mechanism but cannot pass through the limiting rod 4 of the negative dimension detection mechanism, it indicates that the size of the refractory brick is within a reasonable tolerance range. Pull the push-pull block 13 outward to move the limiting tooth 12 away from the toothed ring 8. Pull the vertical rod 3 to adjust the length of the vertical rod 3 extending out of the sleeve 2, and then adjust the height of the limiting rod 4 to accommodate refractory bricks of different specifications. When the vertical rod 3 moves axially along the sleeve 2, the turntable 6 moves axially along the threaded rod 5. The rotation of the turntable 6 drives the toothed ring 8 to rotate. After the adjustment is completed, the push-pull block 13 is released, the slider 10 is reset, and the limiting tooth 12 engages with the toothed ring 8 again to prevent the bushing 7 and the turntable 6 from rotating, thereby keeping the vertical rod 3 and the sleeve 2 fixed.

[0020] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
