Description

Technical Field

[0001] The utility model relates to the technical field of wheel hub production, and more specifically to a device for marking the steel number of a wheel hub curved surface. Background Art

[0002] During the production of aluminum alloy wheels, steel grades need to be stamped on the wheel surface to distinguish different wheels. In the prior art, the steel grade is generally printed on the wheel surface by manually hammering the steel letter code. However, this method cannot ensure the consistency of force applied by workers, resulting in uneven depth of steel grade marks, which looks unsightly, high labor intensity, and easy to hurt hands, posing a safety hazard. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned deficiencies of the prior art and provide a device for marking the curved surface of a hub.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] The utility model discloses a device for striking a steel number on a curved surface of a wheel hub, comprising a positioning piece and a striking piece, wherein a through hole is provided inside the positioning piece, and the striking piece comprises a handle, one end of the handle is connected to a connecting rod, an end of the connecting rod away from the handle is connected to a steel number head, and the end of the connecting rod connected to the steel number head is inserted into the through hole and arranged.

[0006] Furthermore, a limit block is provided at one end of the handle close to the connecting rod, and the diameter of the limit block is greater than the diameter of the through hole.

[0007] Furthermore, the positioning member includes a positioning block, a holding tube and a retaining ring which are connected in sequence, the diameter of the holding tube is smaller than the diameters of the positioning block and the retaining ring, and the steel head is inserted into the through hole at the retaining ring.

[0008] Furthermore, a reinforcement ring is installed on the end surface of the retaining ring away from the holding tube, and the reinforcement ring is arranged around the through hole.

[0009] Furthermore, a positioning groove and a positioning notch are formed on a side of the positioning block away from the holding tube.

[0010] Furthermore, a limiting groove is provided in the positioning member at a position located at the periphery of the through hole, and a convex strip matching the limiting groove is provided at the periphery of the connecting rod.

[0011] The beneficial effect of the utility model is as follows: the positioning piece is placed against the position on the hub curved surface where the steel number needs to be marked, and the end of the connecting rod connected to the steel head is inserted into the through hole. Under the action of gravity, the steel head descends and hits the hub curved surface, so that the steel number can be marked on the hub curved surface. The operation is simple and convenient.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a device for marking a steel number on a curved surface of a wheel hub includes a positioning member 1, a through hole 2 is provided inside the positioning member 1, the through hole 2 is arranged along the length direction of the positioning member 1, and the through hole 2 passes through both ends of the positioning member 1 in the length direction. The positioning member 1 includes a positioning block 8, a holding tube 9 and a retaining ring 10 connected in sequence, and the diameter of the holding tube 9 is smaller than the diameters of the positioning block 8 and the retaining ring 10, so as to facilitate the staff to hold it. The positioning block 8 is used to rest on the curved surface of the wheel hub for positioning. The retaining ring 10 is used to block the handle 4 and limit the descending position of the handle 4. This can prevent the handle 4 from contacting the hand of the staff holding the holding tube 9 when it falls, and can also prevent the steel number head 3 from being hit too hard and causing damage to the curved surface of the wheel hub.

[0021] like Figure 4As shown, the device also includes a striking piece, which includes a handle 4 for the staff to hold. One end of the handle 4 is connected to a connecting rod 5, and the end of the connecting rod 5 away from the handle 4 is connected to a steel head 3. The end of the connecting rod 5 connected to the steel head 3 is inserted into the through hole 2, and the steel head 3 is inserted into the through hole 2 at the retaining ring 10.

[0022] A limit block 6 is provided at one end of the handle 4 close to the connecting rod 5. The diameter of the limit block 6 is larger than the diameter of the through hole 2, so that the limit block 6 cannot enter the through hole 2, thereby playing a limiting role.

[0023] A reinforcing ring 11 is installed on the end surface of the retaining ring 10 away from the gripping tube 9, and the reinforcing ring 11 is arranged around the through hole 2. During long-term use, the retaining ring 10 may be damaged due to the expansion of the limit block 6 on the handle 4 and the retaining ring 10 many times, thereby affecting the position of the limit. By setting the reinforcing ring 11, the reinforcing ring 11 is made of metal and is not easily damaged by collision with the limit block 6, thereby ensuring the accuracy of the limit position of the handle 4. At the same time, the reinforcing ring 11 and the retaining ring 10 are detachably connected, and the reinforcing ring 11 can be removed from the retaining ring 10 for replacement after being worn.

[0024] A positioning groove 12 and a positioning notch 13 are provided on the side of the positioning block 8 away from the holding tube 9. The positioning groove 12 and the positioning notch 13 are set accordingly according to the protruding portion on the hub surface. The positioning groove 12 and the positioning notch 13 are sleeved on the protruding portion to complete the positioning, thereby marking the steel grade at the required position on the hub surface.

[0025] like Figure 5 , Figure 6 As shown, a limiting groove 14 is provided in the positioning member 1 at the periphery of the through hole 2, and a convex strip 15 matching with the limiting groove 14 is provided on the periphery of the connecting rod 5. The cooperation between the limiting groove 14 and the convex strip 15 is used to limit the moving direction of the connecting rod 5 to prevent the connecting rod 5 from rotating or deflecting during the descent process, so as to ensure the consistency of the steel grade position.

[0026] The handle 4 is provided with a plurality of annular grooves 7, which are arranged in parallel. The arrangement of the annular grooves 7 makes the surface of the handle 4 appear concave and convex, so that the staff can hold it better and it is not easy to slip.

[0027] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
