[0020] The technical scheme of the utility model is further illustrated below in combination with the drawings and through specific embodiments.

[0021] As shown in one embodiment of the present application, a tool clamp for automobile wheel hub rim covering is provided, which comprises a bottom supporting ring 10, a side block 11, a lower pressing plate 12 and a locking bolt 13. Figures 1 to 4 The first through holes are at least three in number, and the number of the side blocks 11 and the lower pressing plates 12 is the same as that of the first through holes. The side block 11 is tightly installed on the top of the bottom supporting ring 10, and the side block 11 is tightly installed on the top of the side block 11. The locking bolt 13 passes through the first through holes, the second through holes and the strip-shaped limiting holes 14 in sequence, and the side block 11 and the lower pressing plate 12 are detachably installed above the bottom supporting ring 10.

[0022] In the operation of covering the rim of the automobile wheel hub, the locking bolt 13 is loosened first, and the lower pressing plates 12 installed on the bottom supporting ring 10 are all slid outward, so that the inner end of the lower pressing plate 12 is slid and contracted into the top surface area of the side block 11. Then, the stainless steel edge 50 is placed on the upper surface of the bottom supporting ring, and the stainless steel edge 50 is blocked by the side blocks 11 around the corresponding positions. The inner end of the lower pressing plate 12 is slid inward and pressed on the top of the outer edge of the stainless steel covering, the locking bolt 13 is tightened, and then the stainless steel edge 50 is coated with glue. Finally, the automobile wheel hub is pressed into the stainless steel edge 50, when the automobile wheel hub moves to the lower pressing plate, the locking bolt 13 is loosened, the lower pressing plate 12 is pulled out outward, and finally the rim of the automobile wheel hub is completely attached to the stainless steel and taken out.

[0023] Preferably, the side blocks 11 are multiple, and the sizes of the side blocks 11 along the radial direction of the bottom supporting ring 10 are different. The different sizes of the side blocks 11 can make the tool clamp clamp different sizes of automobile wheel hubs, such as 17 to 20 inch size stainless steel edges 50, which can be stably clamped. The buckle part 15 facilitates the manual pulling and sliding of the lower pressing plate 12 by the operator.

[0024] Preferably, the side stoppers 11 are made of aluminum, and the bottom supporting ring 10 is made of nylon.

[0025] Preferably, the plurality of side stoppers 11 installed on the bottom supporting ring are installed on the same annular member, so that the side stoppers 11 are more convenient to replace or install.

[0026] Another embodiment of the present application is shown in Figure 5 Compared with the above embodiment, the tool clamp further comprises a base 16 and a telescopic cylinder 17; the bottom supporting ring is attached to the base 16; the telescopic cylinder 17 is installed on the base 16 at the peripheral area of the bottom supporting ring; the telescopic driving end of the telescopic cylinder 17 is arranged along the radial direction of the bottom supporting ring and is connected to the outer end of the lower pressing plate 12; under the driving of the telescopic cylinder 17, the lower pressing plate 12 can slide relative to the side stopper. The telescopic cylinder 17 is used to pull out the lower pressing plate 12, so that the tool clamp does not need to manually pull out the lower pressing plate 12, and the degree of automation of the tool clamp is improved, and the clamping operation of the stainless steel rim 50 is facilitated.

[0027] Preferably, the inner end of the lower pressing plate 12 is provided with a sensor 18 for detecting whether the automobile hub is in contact with the inner end of the lower pressing plate; the sensor 18 is electrically connected to the telescopic cylinder 17. When the rim of the automobile hub is attached to the stainless steel rim 50, the lower pressing plate 12 will hinder the automobile hub. Therefore, in order to ensure that the rim of the automobile hub is smoothly attached to the stainless steel rim 50, the lower pressing plate 12 needs to be pulled out at the right time. If the lower pressing plate 12 is pulled out too early, the stainless steel rim 50 will lose the lower pressing force too early, and deformation will occur, which will make the clamping and positioning effect of the tool clamp unsatisfactory. If the lower pressing plate 12 is pulled out too late, it will hinder the automobile hub. Therefore, the sensor 18 is arranged to detect whether the automobile hub is in contact with the lower pressing plate 12. When it is detected that the two are in contact, the telescopic cylinder 17 immediately pulls out the lower pressing plate 12. This is the most efficient and accurate control method.

[0028] Preferably, the sensor 18 is a laser sensor 18 or a pressure sensor 18. There are many ways to detect whether the automobile hub is in contact with the lower pressing plate 12. When the sensor 18 is a laser sensor 18, the distance between the inner end of the lower pressing plate 12 and the automobile hub can be detected by the laser sensor 18, and then whether the automobile hub is in contact with the lower pressing plate 12 can be quickly and accurately detected. When the sensor 18 is a pressure sensor 18, the lower pressing plate 12 will be subjected to the force of the automobile hub after the automobile hub comes into contact with the lower pressing plate 12. The pressure sensor 18 can detect the change in force on the lower pressing plate 12 in real time, and can also quickly and accurately detect whether the automobile hub is in contact with the lower pressing plate 12, which can further improve the clamping accuracy and efficiency of the tool clamp.
