Figure 4 As shown, the elastic member 30 is used to provide elastic force for separating the plug-in assembly 10 from the handwheel assembly 20. The elastic member 30 is used to provide elastic force for separating the plug-in assembly 10 from the handwheel assembly 20, which helps to avoid the handwheel assembly 20 and the driving shaft 200 from rotating synchronously during the high-speed rotation of the plug-in assembly 10 driven by the driving shaft 200, thereby avoiding the high-speed rotation of the handwheel assembly 20, reducing the phenomenon of the handwheel assembly 20 injuring the operator, and achieving the purpose of reducing the safety risk of the handwheel during the processing process.
[0034] Below, combined Figures 1 to 5 , the above-mentioned self-protection handwheel 100 is further explained.
[0035] like Figure 2 and Figure 4 As shown, the socket 11 includes a socket body 15, a positioning member 16, a blocking member 17 and a mounting member 18. Figure 2 As shown, the seat body 15 is provided with a sleeve hole 151 and a positioning groove 152 communicating with the sleeve hole 151, and the sleeve hole 151 is sleeved with the driving shaft 200. Figure 3 and Figure 4As shown, the positioning member 16 is installed on the driving shaft 200 and inserted into the positioning groove 152, the blocking member 17 is connected to the seat body 15 and forms a slide groove 111 with the seat body 15, and the mounting member 18 is connected to the driving shaft 200 and forms a mounting groove 19 for mounting the seat body 15 with the driving shaft 200, wherein the blocking member 17 is a retaining spring and is clamped on the seat body 15. The mounting groove 19 can prevent the seat body 15 from moving along its axis, which is equivalent to the driving shaft 200, thereby improving the installation stability of the seat body 15.
[0036] Furthermore, if Figure 2 As shown, the seat body 15 includes a connecting portion 153 and an adapter portion 154, the connecting portion 153 is provided with a sleeve hole 151 and a positioning groove 152, the adapter portion 154 is connected to the insertion rod 12, the number of the insertion rods 12 is multiple, and each insertion rod 12 is arranged around the axis of the driving shaft 200, the mounting member 18 includes a blocking shaft 181 and a fixing member 182, the blocking shaft 181 and the driving shaft 200 form a mounting groove 19, the fixing member 182 passes through the blocking shaft 181 and is connected to the driving shaft 200, wherein the fixing member 182 is a screw.
[0037] like Figure 4 As shown, the handwheel assembly 20 is rotatably mounted on the socket 11 and moves closer to or farther away from the plug rod 12 along the slide slot 111 . The handwheel assembly 20 is provided with a socket 221 that cooperates with the plug rod 12 , and the number of the sockets 221 is the same as the number of the plug rod 12 .
[0038] Specifically, Figure 4 As shown, the handwheel assembly 20 includes a slide 21, a mother seat 22 and a wheel disc 23. The slide 21 is slidably installed on the slide groove 111, the mother seat 22 is sleeved on the slide 21, and is provided with a socket 221, and the wheel disc 23 is sleeved on the mother seat 22, wherein the slide 21 is a linear bearing and has an interference fit with the mother seat 22. The slide 21 adopts an interference fit with the mother seat 22, which helps to avoid the slide 21 from getting stuck with the seat body 15, and the slide 21 may injure the operator due to the rigid connection with the mother seat 22, thereby increasing the safety redundancy of the handwheel assembly 20.
[0039] Furthermore, if Figure 4 As shown, the female seat 22 includes a main body 222, a docking portion 223 and a protective portion 224. The docking portion 223 is provided with a socket 221. The protective portion 224 is arranged around the docking portion 223 and extends along the axis of the active shaft 200 toward the direction of the insertion rod 12. The insertion rod 12 is separated from external objects by the protective portion 224, which can effectively reduce the entry of external objects between the docking portion 223 and the adapter portion 154, thereby reducing damage to the high-speed rotating insertion rod 12 or being bounced off by the high-speed rotating insertion rod 12, thereby improving the safety of the use of the insertion rod 12.
[0040] like Figure 4 and Figure 5As shown, the roulette wheel 23 includes a disc body 231 and a touch portion 232. The disc body 231 is sleeved on the mother seat 22 and has an interference fit with the mother seat 22. There are multiple touch portions 232, and each touch portion 232 is arranged around the disc body 231. The touch portion 232 is beneficial to improving the operating accuracy of the operator on the roulette wheel 23, so as to achieve the purpose of improving the control accuracy of the operator.
[0041] like Figure 4 As shown, the elastic member 30 is a spring and is sleeved on the slide slot 111 of the plug assembly 10 to provide elastic force for the hand wheel assembly 20 to move away from the plug rod 12 .
[0042] like Figure 4 As shown, the working principle of the self-protection handwheel 100 described in the utility model is: the elastic member 30 drives the handwheel assembly 20 away from the plug rod 12 through the elastic force provided by it, so that the plug rod 12 is separated from the socket 221. During the high-speed rotation of the active shaft 200, the active shaft 200 drives the socket 11 and the plug rod 12 on the socket 11 to rotate at a high speed. Since the plug rod 12 is separated from the socket 221 at this time, the handwheel assembly 20 can rotate freely relative to the socket 11 rotating at a high speed with the active shaft 200. When the active shaft 200 stops rotating and manual operation is required, the handwheel assembly 20 is controlled to approach the plug rod 12 along the slide groove 111 so that the plug rod 12 is combined with the socket 221, and then the handwheel assembly 20 is rotated, so that the socket 11 can be controlled by the handwheel assembly 20 to drive the active shaft 200 to rotate.
[0043] The beneficial effect of the self-protection handwheel 100 described in the utility model is: the elastic member 30 is used to drive the handwheel assembly 20 away from the insertion rod 12 through the elastic force provided by the elastic member 30, so that the insertion rod 12 is separated from the insertion hole 221, which is conducive to preventing the active shaft 200 from driving the plug-in assembly 10 to rotate at high speed and driving the handwheel assembly 20 to rotate synchronously, thereby avoiding the handwheel assembly 20 from rotating at high speed, reducing the phenomenon of the handwheel assembly 20 injuring the operator, and achieving the purpose of reducing the safety risk of the handwheel during the processing process.
[0044] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0045] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
