Description

Technical Field

[0001] This utility model relates to the field of workpiece processing tooling technology, and more specifically, to a tooling for workpiece grinding. Background Technology

[0002] After the workpiece is cast, its ends need to be ground. The current practice is for workers to hold the workpiece close to the grinding wheel of a grinding machine, allowing the rotating wheel to grind the ends. However, this process presents several problems: 1. The worker's hand is too close to the grinding wheel, increasing the risk of injury and posing a significant safety hazard. 2. The heat generated during grinding is directly transferred to the worker's hands, potentially causing burns. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a workpiece grinding fixture. When the workpiece is assembled on the workpiece grinding fixture and ground by a grinding wheel, it can effectively eliminate the safety hazard of the grinding wheel injuring the worker's hands, and can effectively overcome the problem of hot hands during the workpiece grinding process.

[0004] This utility model provides a workpiece grinding fixture, including a support base and a handle rod; the upper end of the handle rod is welded and fixed to the middle of the outer bottom of the support base, and the upper end of the support base is provided with a cavity for the workpiece to be inserted from top to bottom, and the inner contour shape of the cavity is adapted to the outer contour shape of the workpiece.

[0005] By adopting the above-described structure, this utility model allows the workpiece to be inserted into the cavity before grinding. Then, the worker holds the handle to bring the upper end of the workpiece close to the grinding wheel of the grinding machine. Due to the support base and handle, the worker's hands are kept away from the grinding wheel, thus effectively eliminating the safety hazard of the grinding wheel injuring the worker's hands. Furthermore, the support base and handle effectively prevent the heat generated during workpiece grinding from being transferred to the worker's hands, thereby effectively overcoming the problem of scalding hands during workpiece grinding.

[0006] In one possible implementation, the handle bar has a rectangular cross-section; by adopting a handle bar with this cross-sectional shape, the rotation of the handle bar relative to the user's hand can be effectively prevented when the user holds the handle bar, thereby improving the reliability and stability of the user's grip on the handle bar.

[0007] In one possible implementation, a heat-insulating rubber sleeve is fitted over the lower end of the handle, and the heat-insulating rubber sleeve fits tightly with the handle. By fitting the heat-insulating rubber sleeve over the lower end of the handle, the heat-insulating rubber sleeve can effectively isolate the transfer of heat, thereby further preventing the heat generated during workpiece grinding from being transferred to the user's hand through the support and handle, thus further achieving the purpose of preventing burns. Furthermore, the heat-insulating rubber sleeve can further increase the friction between the handle and the user's hand, thereby further achieving the purpose of preventing slippage. The aforementioned heat-insulating rubber sleeve is an existing component on the market, so it will not be described in detail here.

[0008] In one possible implementation, a plurality of annular anti-slip grooves are provided on the outer peripheral wall of the heat-insulating rubber sleeve, and the plurality of annular anti-slip grooves are spaced apart along the vertical direction of the heat-insulating rubber sleeve; by adopting this structure, when the user's hand holds the heat-insulating rubber sleeve, the friction between the hand and the heat-insulating rubber sleeve can be further increased, thereby further achieving the purpose of anti-slip.

[0009] In one possible implementation, a number of circumferentially distributed reinforcing blocks are provided at the connection between the upper end of the handle and the outer bottom of the support base. The reinforcing blocks are welded and fixed to the outer wall of the upper end of the handle and the outer bottom of the support base. By welding and fixing the reinforcing blocks at the connection between the handle and the support base, the connection strength between the upper end of the handle and the outer bottom of the support base can be further improved, so as to effectively prevent the handle from detaching from the support base.

[0016] The present application will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0017] See Figure 1-3 As shown in the figure, this application discloses a workpiece grinding fixture, including a support base 1 and a handle rod 2; the upper end of the handle rod 2 is welded and fixed to the middle of the outer bottom of the support base 1, and the upper end of the support base 1 is provided with a cavity 11, which is used for the workpiece 3 to be inserted from top to bottom, and the inner contour shape of the cavity 11 is adapted to the outer contour shape of the workpiece 3.

[0018] The handle 2 has a rectangular cross-section. By adopting this cross-sectional shape, the handle can be effectively prevented from rotating relative to the user's hand when the user holds it, thereby improving the reliability and stability of the user's grip.

[0019] A heat-insulating rubber sleeve 4 is fitted onto the lower end of the handle 2, and the heat-insulating rubber sleeve 4 fits tightly with the handle 2. By fitting the heat-insulating rubber sleeve onto the lower end of the handle, the heat-insulating rubber sleeve can effectively isolate the transfer of heat, thereby further preventing the heat generated during workpiece grinding from being transferred to the user's hand through the support base and the handle, thus further achieving the purpose of preventing burns. Furthermore, the heat-insulating rubber sleeve can further increase the friction between the handle and the user's hand, thereby further achieving the purpose of preventing slippage. The aforementioned heat-insulating rubber sleeve is an existing component on the market, so it will not be described in detail here.

[0020] The outer peripheral wall of the heat-insulating rubber sleeve 4 is provided with several annular anti-slip grooves 41, which are distributed at intervals along the vertical direction of the heat-insulating rubber sleeve 4. By adopting this structure, when the user's hand holds the heat-insulating rubber sleeve, the friction between the hand and the heat-insulating rubber sleeve can be further increased, thereby further achieving the purpose of anti-slip.

[0021] Several reinforcing blocks 5 are arranged in a circumferential manner at the connection between the upper end of the handle rod 2 and the outer bottom of the support base 1. The reinforcing blocks 5 are welded and fixed to the outer side wall of the upper end of the handle rod 2 and the outer bottom of the support base 1. By welding and fixing several circumferentially distributed reinforcing blocks at the connection between the handle rod and the support base, the connection strength between the upper end of the handle rod and the outer bottom of the support base can be further improved, so as to effectively prevent the handle rod from detaching from the support base.
