Description

Technical Field

[0001] This utility model relates to the technical field of center tooth base, specifically a center tooth base for a grinding machine. Background Technology

[0002] Currently used center gear bases are made of highly wear-resistant metals to ensure their service life. However, for center gear bases that produce tens or even hundreds of thousands of workpieces, the accumulated wear and tear over time leads to a significant reduction in their accuracy, making them unable to support the workpieces effectively.

[0003] In order to ensure its stability, the existing center tooth base is reinforced with multiple screws. Although screws are simple in structure, they are complicated to tighten, making disassembly inconvenient. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A grinding machine center tooth base includes a support mechanism and a limiting mechanism. The support mechanism includes a support base, a side plate connected to the front side of the support base, a guide rod suspended above the top of the support base and connected to the side plate, a tooth seat fitted to the top of the support base and inserted into the guide rod, and two V-faces provided on the top of the tooth seat. The limiting mechanism includes a cylinder connected to the support base, a lifting plate connected to the movable end of the cylinder, and two rod sleeves movably sleeved at both ends of the guide rod and connected to the lifting plate. The rod sleeves fit against the outer side of the tooth seat.

[0007] By adopting the above technical solution, when replacing the gear seat, the moving end of the control cylinder retracts, and then the lifting plate descends with the rod sleeve. When the rod sleeve descends to the bottom of the gear seat, the worker can remove the gear seat along the guide rod. The structure is simple and the disassembly is convenient.

[0008] In a preferred embodiment, the present invention can be further configured such that the length of the guide rod is greater than the length of the toothed seat, and the support, guide rod, and toothed seat are all made of highly wear-resistant metal material.

[0009] In a preferred embodiment, the present invention can be further configured such that the bottom end of the V-surface is set as an arc surface.

[0010] In a preferred embodiment, the present invention can be further configured such that the support has multiple threaded holes arranged in a matrix.

[0011] In a preferred embodiment, the present invention can be further configured such that: two vertical rods are installed on the support, and the lifting plate is slidably connected between the two vertical rods.

[0012] In a preferred embodiment, the present invention can be further configured such that two vertical rods are located on both sides of the cylinder, and the vertical rods are made of the same material as the guide rods.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, when replacing the gear seat, the movable end of the control cylinder retracts, and then the lifting plate descends with the rod sleeve. When the rod sleeve descends to the bottom of the gear seat, the worker can remove the gear seat along the guide rod. The structure is simple and the disassembly is convenient.

[0015] 2. In this utility model, the tooth holder is attached to the top of the support under the limit of the guide rod. Then, the moving end of the cylinder is in the extended state. Then, the lifting plate connected to the cylinder, with two rod sleeves, is fitted on both ends of the guide rod, thereby preventing the tooth holder from shifting left and right, so that the tooth holder can stably support the workpiece. Under the guidance of the V-surface, the center of the workpiece can be located on the same axis as the output end of the external grinding machine, ensuring the workpiece production effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0025] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0026] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a center tooth base for a grinding machine.

[0027] Example 1:

[0028] Combination Figure 1-3 As shown, the present invention provides a grinding machine center tooth base, including a support mechanism 100 and a limiting mechanism 200. The support mechanism 100 includes a support base 110, a side plate 120 connected to the front side of the support base 110, a guide rod 130 suspended above the top of the support base 110 and connected to the side plate 120, a tooth seat 140 attached to the top of the support base 110 and inserted into the guide rod 130, and two V-surfaces 150 provided on the top of the tooth seat 140.

[0029] The limiting mechanism 200 includes a cylinder 210 connected to the support 110, a lifting plate 220 connected to the movable end of the cylinder 210, and two rod sleeves 230 movably sleeved at both ends of the guide rod 130 and connected to the lifting plate 220. The rod sleeves 230 fit against the outside of the gear seat 140.

[0030] Furthermore, the length of the guide rod 130 is greater than the length of the gear seat 140. The support seat 110, guide rod 130, and gear seat 140 are all made of high wear-resistant metal material. The size design of the guide rod 130 allows it to completely limit the gear seat 140. At the same time, the use of high wear-resistant metal material as the manufacturing material ensures the service life of the support seat 110, guide rod 130, and gear seat 140.

[0031] Furthermore, the bottom end of the V-surface 150 is set as an arc surface. The shape design of the V-surface 150 allows the workpiece supported by the tooth seat 140 to completely fit the V-surface 150.

[0032] Example 2:

[0033] Combination Figure 1-3 As shown, based on Embodiment 1, the support 110 is provided with a plurality of threaded holes 300, which are arranged in a matrix. The threaded holes 300 can be used to firmly connect the support 110 to the external grinding machine.

[0034] Example 3:

[0035] Combination Figure 1As shown in the above embodiment, two vertical rods 400 are installed on the support 110, and the lifting plate 220 is slidably connected between the two vertical rods 400. The vertical rods 400 can guide the lifting plate 220, making the lifting plate 220 rise and fall more smoothly.

[0036] Furthermore, the two vertical rods 400 are located on both sides of the cylinder 210. The vertical rods 400 are made of the same material as the guide rod 130. The layout design of the vertical rods 400 can stably guide the lifting plate 220. At the same time, the use of highly wear-resistant materials can ensure the service life of the vertical rods 400.

[0037] The working principle and usage process of this utility model are as follows: In the initial state, the gear seat 140 is attached to the top of the support seat 110 under the limit of the guide rod 130. Then, the movable end of the cylinder 210 is in an extended state. Then, the lifting plate 220 connected to the cylinder 210, with two rod sleeves 230, is fitted onto both ends of the guide rod 130, thereby preventing the gear seat 140 from shifting left and right and enabling the gear seat 140 to stably support the work. Then, when removing the severely worn gear seat 140, the movable end of the cylinder 210 is controlled to retract, and then the lifting plate 220 with the rod sleeves 230 descends. When the rod sleeves 230 descend to the bottom of the gear seat 140, the operator can remove the gear seat 140 along the guide rod 130. The structure is simple and the disassembly is convenient.

[0038] Although embodiments of the present invention have been shown and described, those skilled in the art will understand 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 claims and their equivalents.
