Description

Technical Field

[0001] The utility model belongs to the technical field of top hammer processing, in particular to a clamping mechanism for a top hammer chamfering processing device. Background Art

[0002] Publication number CN217453384U discloses a cemented carbide anvil chamfering processing mechanism, including a fixture and a grinding assembly. The fixture is cylindrical as a whole, and the top of the fixture is provided with four clamping blocks evenly distributed along the circumference. The inner surface of each clamping block is an inclined surface consistent with the conical surface inclination of the top of the cemented carbide anvil. The four-petal clamping blocks enclose a placement cavity that can fit tightly with the top of the cemented carbide anvil. Its technical solution realizes semi-automatic processing of cemented carbide anvil chamfering through the cooperation of the fixture and the grinding assembly. Its technical solution only places the anvil directly on the fixture, and lacks clamping of the upper end and side of the anvil.

[0003] In order to solve the above problems, publication number CN220074254U discloses a clamping mechanism for a top hammer chamfering processing device, including a fixed platform for supporting and rotating the top hammer, a pressure head assembly is provided above the fixed platform, and the pressure head assembly is equipped with a lifting mechanism for realizing the up and down movement of the pressure head assembly, and uniform pressure is applied to the upper end surface of the top hammer through the clamping member, and the friction between the clamping member and the upper end surface of the top hammer is small, making the top hammer more stable, avoiding shaking or offsetting of the top hammer during rotation, and not affecting the chamfering of the top hammer, and having the advantage of making the chamfering of the top hammer more uniform. Its technical solution only realizes the longitudinal clamping of the top hammer, ensuring the stability of the top hammer in the longitudinal direction, but the cemented carbide top hammer is basically a smooth cylindrical structure as a whole, and the chamfering processing mechanism will apply a lateral component of force to the top hammer during grinding. The lack of sufficient lateral support for the top hammer can easily cause the top hammer to swing loosely, and it is difficult to ensure the clamping stability of the cemented carbide top hammer.

Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1

[0022] See also Figure 1-4As shown, a clamping mechanism for a top hammer chamfering processing device includes a fixed table 1, a support plate 2 is vertically arranged on the side of the fixed table 1, and a transverse support assembly 3 is arranged on the support plate 2 for movably contacting the side of the cylindrical part of the top hammer 4.

A top plate 5 is provided on the upper end of the support plate 2, and a pressure head assembly 6 is vertically arranged downward at the other end of the top plate 5. The fixed table 1 includes a table body and a rotating mechanism, wherein the table body can adopt any existing chamfering processing device for having the same inclination angle as the cone surface of the top hammer and realizing coaxial support and positioning of the top hammer, the rotating mechanism can adopt any existing chamfering processing device for causing the top hammer to rotate, or it can adopt a driving motor plus a worm gear structure to be linked with the table body, and the chamfering mechanism is arranged on a side of the fixed table 1 away from the support plate 2. The specific structures of the table body, the rotating mechanism and the chamfering mechanism have been disclosed in the clamping mechanism for the top hammer chamfering processing device disclosed in publication number CN220074254U, and will not be repeated here.

[0023] When the top hammer is grinding through the chamfering mechanism, the top hammer rotates at a uniform speed through the rotating mechanism, and several roller groups contact the side surface of the top hammer in sequence along the circumference of the side surface of the top hammer. Therefore, when the top hammer is grinding, several roller groups can support the side surface of the top hammer, thereby improving the lateral supporting force of the top hammer and further improving the stability of the top hammer during chamfering processing.

[0024] The lateral displacement member includes a first oil cylinder 34, which is horizontally arranged in the left-right direction. The cylinder body of the first oil cylinder 34 is connected to the support plate 2. The piston rod of the first oil cylinder 34 is provided with a roller seat 33. The side of the roller seat 33 near the top hammer 4 is provided with a roller shell 32. While the top hammer is placed on the fixed platform 1, the first oil cylinder 34 is in a retracted state, at which time the plurality of roller assemblies 31 are moved away from the fixed platform 1, reducing the impact of the plurality of roller assemblies 31 on the top hammer during placement on the fixed platform 1. After placement, the first oil cylinder extends, causing the plurality of roller assemblies 31 to fit against the side of the top hammer, ensuring that the plurality of roller assemblies 31 rotates with the top hammer.

[0025] The roller shell 32 includes an arc-shaped plate 35 coaxially arranged with the top hammer 4. A first support plate 36 is provided along the arc of the upper end of the arc-shaped plate 35, and a second support plate 37 is provided along the arc of the lower end of the arc-shaped plate 35. The roller assembly 31 includes a rotating shaft 311, which is arranged vertically along its axis. The upper and lower ends of the rotating shaft 311 are connected to the first support plate 36 and the second support plate 37 respectively via bearings 313. A wheel body 312 is coaxially mounted on the rotating shaft 311. A plurality of wheel bodies 312 are provided, and the plurality of wheel bodies 312 are arranged at equal intervals along the axis of the rotating shaft 311. Two first oil cylinders 34 are provided, and the two first oil cylinders 34 are located on the same horizontal plane and operate synchronously.

[0026] The pressure head assembly 6 includes a pressure plate 61 and a second oil cylinder 64, the second oil cylinder 64 is arranged vertically downward, the cylinder body of the second oil cylinder 64 is connected to the top plate 5, and the piston rod of the second oil cylinder 64 is connected to the pressure plate 61 through a rotating member; the rotating member includes a pressure plate seat 63, and a connecting column 67 is vertically downwardly provided in the middle of the lower end surface of the pressure plate seat 63, and the lower end of the connecting column 67 is coaxially connected to the pressure plate sleeve 65 through a second bearing 66, and the lower end of the pressure plate sleeve 65 is coaxially connected to the upper end surface of the pressure plate 61; there are two second oil cylinders 64, and the two second oil cylinders 64 work synchronously and are respectively located at the front and rear ends of the upper end surface of the pressure plate seat 63. While the top hammer is being placed on the fixed platform 1, the second oil cylinder 64 is in a retracted state. At this time, the pressure plate 61 is located at the top, reducing the influence of the pressure plate 61 on the top hammer during the period of placement on the fixed platform 1. After placement, the second oil cylinder extends to make the lower end surface of the pressure plate 61 fit with the upper end surface of the top hammer, so that the pressure plate 61 rotates with it when the top hammer rotates.

By providing a plurality of brushes, the dust attached to the side of the top hammer can be cleaned before the wheel body 312 contacts the side of the top hammer, further improving the stability of the top hammer during rotation and improving the chamfering accuracy of the top hammer.
