Description

Technical Field

[0001] The utility model relates to the technical field of parts polishing, in particular to a polishing device for a lathe. Background Art

[0002] When machining shaft parts on a lathe, the surface roughness of the machined part is generally not more than 1.6 to 3.2, or even lower, due to the influence of the machine tool, tool performance, and machining parameters. If a higher roughness is to be achieved, grinding is required. However, if the roughness requirement is not particularly high, a polishing machine can be used on the lathe for polishing (1.6 to 0.8), without the need for grinding on a grinder.

[0003] The utility model patent with announcement number CN202910698U discloses a lathe polishing device, which includes a manual angle grinder, and the manual angle grinder is clamped and ground to be converted into a structure capable of clamping a polishing wheel. Then it is clamped on the lathe tool holder to work, the cutting speed is doubled, and the workpiece surface meets the roughness requirement. The above polishing device can polish ordinary shaft parts normally, but for shaft parts with flanges, such as Figure 6 and Figure 7 As shown, the polishing device is installed on both sides of the tool holder. Due to the width of the tool holder and the width of the polishing device, when polishing the outer circle between the two flanges, the left and right sides are restricted, resulting in the inability to polish the middle part. Utility Model Content

[0004] The purpose of the utility model is to provide a lathe polishing device to solve the problem that when the existing polishing device is used to polish the outer circle between two flanges, the left and right sides are restricted, resulting in the inability to polish the middle part. In order to achieve the above purpose, the utility model solves the problem through the following technical solutions:

[0005] The utility model provides a polishing device for a lathe, comprising a polishing frame and an angle grinder;

[0006] Wherein, the polishing frame comprises:

[0007] The clamping block is arranged transversely and is used to connect the lathe tool holder;

[0008] A bracket, connected to the clamping block, used to support the angle grinder and arrange the polishing wheel rotation axis in a transverse direction;

[0009] In the transverse direction, the polishing wheel is located on one of the left and right sides of the clamping block; in the longitudinal direction, the polishing wheel is located on the front side of the clamping block.

[0010] As a further technical solution, the angle grinder is tilted, and one end of the polishing wheel is lower than the other end.

[0011] As a further technical solution, the bracket is a triangular bracket, which is composed of an L-shaped bracket and a connecting rod.

[0012] As a further technical solution, the clamping block is a rectangular block, and the vertical side of the L-shaped bracket is vertically connected to the clamping block.

[0013] As a further technical solution, the L-shaped bracket is welded to the connecting rod, and the L-shaped bracket is welded to the clamping block.

[0014] As a further technical solution, a reinforcing rib is provided between the L-shaped bracket and the clamping block.

[0015] As a further technical solution, the body of the angle grinder is mounted on the connecting rod so as to maintain an inclined posture.

[0016] As a further technical solution, at least one fixing hoop for fixing the angle grinder body is provided on the connecting rod.

[0017] As a further technical solution, one fixing hoop is provided at the top and one at the bottom.

[0018] As a further technical solution, the polishing wheel is a flap wheel.

[0019] The beneficial effects of the above utility model are as follows:

[0020] (1) The utility model arranges the clamping block horizontally, extends the bracket to the front side, and limits the position of the polishing wheel. After the polishing machine frame is installed, the angle grinder and its polishing wheel can be installed on the front part of the lathe tool holder, thereby reducing the restricted size, completing the polishing of the middle part of the part, and further realizing the polishing of the entire area between the two flanges.

[0021] (2) The utility model tilts the angle grinder at a certain angle through a tripod, thereby avoiding the problem of instability caused by excessive overhang when the angle grinder is installed horizontally, and the problem that the angle grinder fixing hoop is close to the outer circle of the part to be processed when the angle grinder is installed vertically, and when the grinding wheel is ground small, the fixing hoop may contact the outer circle of the part.

DETAILED DESCRIPTION

[0031] The technical solutions in typical embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] like Figure 1 As shown, this embodiment provides a polishing device for a lathe, including a polishing frame 100 and an angle grinder 200 .

[0033] like Figure 2 As shown, the polishing frame 100 includes:

[0034] The clamping block 110 is arranged transversely and is used to connect the lathe tool rest 300. In this embodiment, the clamping block 110 is a rectangular block and can be clamped in the front part of the lathe tool rest 300 transversely.

[0035] The bracket is connected to the clamping block 110, and is used to support the angle grinder 200 and arrange the rotation axis of the polishing wheel 220 transversely. That is, the rotation axis of the polishing wheel 220 is arranged parallel to the clamping block 110. Figure 3 As shown, the polishing wheel 220 on the angle grinder 200 rotates tangentially to the outer circle of the part 400 to be processed for polishing.

[0036] In the horizontal direction, the polishing wheel 220 is located on one side of the clamp block 110 to avoid the lathe tool holder 300 from limiting the polishing area. In addition, it should be noted that in order to achieve the complete polishing of the area between the two flanges, two polishing devices are required, with the polishing wheel 220 being located on each side of the clamp block 110. Figure 4 and Figure 5 In the longitudinal direction, the polishing wheel 220 is located at the front side of the clamping block 110 , so that the working position of the polishing wheel 220 is located at the front part of the lathe tool post 300 .

[0037] In the prior art, such as Figure 6 and Figure 7 As shown in FIG. 1 , the polishing stroke is less than half of the polishing area, and after two polishing strokes, the middle part cannot be polished. Figure 4 and Figure 5 As shown, one polishing stroke exceeds half of the polishing area, and the two polishing strokes overlap in the middle part, so the middle part can be polished.

[0038] In this embodiment, by arranging the clamping block 110 horizontally, extending the bracket to the front side, and limiting the position of the polishing wheel 220, the angle grinder 200 and its polishing wheel 220 can be installed to the front of the lathe tool holder after the polishing machine frame 100 is installed, thereby reducing the restricted size, completing the polishing of the middle part of the part, and further realizing the polishing of the entire area between the two flanges.

[0039] The angle grinder 200 is installed on the front of the lathe tool holder 300. If the angle grinder 200 is installed horizontally, the length of the angle grinder 200 is too large, resulting in excessive overhang and instability; if the angle grinder 200 is installed vertically, the fixed hoop of the angle grinder 200 is close to the outer circle of the part to be processed 400. When the grinding wheel is ground small, the fixed hoop may contact the outer circle of the part. Therefore, it is necessary to tilt the angle grinder 200 at a certain angle, and this is achieved through a tripod. The angle grinder 200 is tilted, and one end of the polishing wheel 220 is lower than the other end, that is, the head of the body 210 is lower than the tail.

[0040] The bracket of this embodiment is a triangular bracket, which is composed of an L-shaped bracket 120 and a connecting rod 130. The L-shaped bracket 120 and the connecting rod 130 are welded to form a triangular bracket, and the L-shaped bracket 120 and the clamping block 110 are welded.

[0041] During installation, one side of the L-shaped bracket 120 is placed vertically, and the vertical side is vertically connected to the clamping block 110 .

[0042] In order to increase the connection strength between the L-shaped bracket 120 and the clamping block 110 , a reinforcing rib 160 is provided between the L-shaped bracket 120 and the clamping block 110 , and the two are connected by welding.

[0043] The connecting rod 130 is welded to the L-shaped bracket 120 and is in an inclined state, so the body 210 of the angle grinder 200 is mounted on the connecting rod 130 to keep the inclined posture.

[0044] The connecting rod 130 is provided with at least one fixing hoop for fixing the body 210 of the angle grinder 200. In this embodiment, one fixing hoop is provided at the top and one at the bottom, namely an upper fixing hoop 140 and a lower fixing hoop 150. The upper fixing hoop 140 fixes the tail of the body 210 of the angle grinder 200, and the lower fixing hoop 150 fixes the head of the body 210 of the angle grinder 200.

[0045] The upper fixing hoop 140 and the lower fixing hoop 150 are both composed of two semicircular hoops and are detachable structures. The two semicircular hoops are fastened to the angle grinder 200 by bolts.

[0046] In this embodiment, the polishing wheel 220 is a flap wheel. The specific structure of the flap wheel belongs to the existing technology and can be purchased in the market according to demand, so it will not be described in detail here.

[0047] Although the utility model has been disclosed as above in the form of a preferred embodiment, it is not intended to limit the utility model. Any technical personnel in this field can make possible changes and modifications to the technical solution of the utility model by using the methods and technical contents disclosed above without departing from the spirit and scope of the utility model. Therefore, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model are within the protection scope of the technical solution of the utility model.
