[0032] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0033] Reference Figures 1 to 3 The present embodiment provides a camshaft processing tool, including a housing 1, wherein a accommodating cavity 11 with a top opening is provided in the housing 1, and a cooling fluid 12 is provided in the accommodating cavity 11. The cooling fluid 12 is cooling oil, cooling water or cooling gas, and is used to perform oil cooling, water cooling or air cooling on the workpiece 5.

[0034] Reference Figures 1 to 3, further comprising a transverse movement assembly 2, mounted on the top surface of the side wall of the box body 1; the transverse movement assembly 2 comprises a slide rail 22, an electric pulley mounted on the slide rail 22, and a slide plate 21 mounted on the electric pulley. The electric pulley is capable of moving synchronously with the slide plate 21 on the slide rail 22. The box body 1 further comprises a diagonal bracing assembly 3, comprising a diagonal bracing rod 31, one end of which is positioned on the upper surface of the slide plate 21 and connected to the slide plate 21 via a hinge, and the other end of which is positioned within the accommodating cavity 11.

[0035] Reference Figure 2 and Figure 3 The slide rails 22 are provided in two groups and are respectively provided on the left and right side walls of the box body 1; each group of the slide rails 22 is provided with two electric pulleys and two slide plates 21 installed corresponding to the electric pulleys. The transverse movement components 2 are provided in four groups and are installed in pairs, and each pair of the diagonal support components 3 cross each other to form an X shape. Figure 3 The left and right slides 21 form a group and maintain synchronous movement to drive a pair of transverse moving components 2 to translate along the length direction of the box 1. The spacing between the two groups of slides 21 can be changed to adjust the spacing between the two pairs of transverse moving components 2, which is used to adapt to the overlap of workpieces 5 of different lengths.

[0036] Reference Figure 2 The two ends of the workpiece 5 are respectively overlapped on the intersection of the two pairs of transverse movement components 2 to achieve positioning, which can avoid the problem of uneven cooling of the crimping position of the workpiece 5 caused by the workpiece 5 being pressed against the bottom plate of the inner cavity of the box body 1; at the same time, the transverse movement component 2 only contacts the end of the workpiece 5, which can ensure that the working surface of the workpiece 5 is completely immersed in the cooling fluid 12 without contacting the bottom plate.

[0037] Reference Figure 3 and Figure 4 , further comprising four lifting assemblies 4, each connected to one of the four diagonal brace assemblies 3. Each lifting assembly 4 is used to lift or lower the end of a corresponding diagonal brace 31. When the ends of a pair of diagonal braces 31 are lifted simultaneously, the workpiece 5 positioned at the intersection of the diagonal braces 31 is lifted upward until it is lifted out of the cooling fluid 12. This avoids the difficulty of submerging the fixture in the cooling fluid 12 to hold the workpiece 5, as is common with conventional techniques.

[0038] Reference Figures 3 to 5The lifting assembly 4 includes a pulley block 41, a cable 42, and a winch 43. The pulley block 41 is mounted on the slide 21 on the hinge side. One end of the cable 42 is connected to the lower end of the diagonal support rod 31, and the other end of the cable 42 is connected to the winch 43. The middle of the cable 42 is pressed against the pulley block 41. Each pulley block 41 includes two pulleys, which extend from the slide 21 to the sides and extend outward from the edge of the slide 21 to prevent the cable 42 from contacting and wearing the top of the side wall of the box body 1.

[0039] The outer edge of the slide plate 21 extends downward to form an extension plate 211, and the winch 43 is fixedly connected to the extension plate 211. The extension plate 211 is used to provide installation space for the winch 43. When the electric pulley moves, it can drive the winch 43 to move synchronously to adapt to the movement of the diagonal support rod 31, the cable 42 and the pulley block 41, thereby maintaining normal transmission of the lifting assembly 4.

[0040] Reference Figure 4 The slide plate 21 and the extension plate 211 are fixedly connected in a 7-shape (for example, through an integrated fixed connection).

[0041] Reference Figure 4 and Figure 6 The bottom end of the extension plate 211 is mounted with a support wheel 212. The outer wall of the box body 1 is mounted with a support rail 13 (for example, fixedly connected by bolts). The upper surface of the support rail 13 is provided with a rolling groove, and the support wheel 212 is pressed into the rolling groove. The cross-section of the rolling groove is an inverted trapezoid.

[0042] The side wall of the housing 1 is provided with a feed inlet and a discharge inlet, with the feed inlet located at the top end of the side wall and the discharge inlet located at the bottom end. The feed inlet is connected to and communicates with the feed pipe, while the discharge inlet is connected to and communicates with the discharge pipe. A first valve body is mounted on the feed pipe, while a second valve body is mounted on the discharge pipe. Cooling fluid 12 from an external storage container flows through the feed pipe into the accommodating chamber 11 of the housing 1 using a liquid pump, an air pump, or its own pressure. The user periodically opens the second valve body to drain and replace the cooling fluid 12 in the accommodating chamber 11.

[0043] The utility model further includes an electrical cabinet, which is bolted to the outer wall of the housing 1. The electric pulley and the winch 43 are connected to the electrical cabinet via wires and signal lines. The electrical cabinet is also connected to an external power supply and an external computer via wires and signal lines. The computer controls the start and stop of the electric pulley and the winch 43 through the electrical cabinet to achieve adaptive motion.

[0044] A first robotic arm and a second robotic arm are respectively provided on the workbenches on the left and right sides of the box body 1. When in use, the first robotic arm grabs the high-temperature workpiece 5 and places it on the upper end of the diagonal support rod 31, and then the workpiece 5 rolls along the diagonal support rod 31 to the intersection position; after the oil cooling / water cooling / air cooling is completed, the lifting component 4 pulls up the diagonal support rod 31 until the diagonal support rod 31 lifts the workpiece 5 out of the cooling fluid 12, and then the second robotic arm grabs the workpiece 5 and places it on the next processing station. Compared with the traditional clamping cooling method, it can avoid the problem of the robotic arm being occupied for a long time.

[0045] The utility model has a simple structure and reliable function; the diagonal support rods 31 of the diagonal support assembly 3 are arranged in an X shape and cross-wise, which are used to lift and position the workpiece 5 to prevent the workpiece 5 from sinking to the bottom; the lifting assembly 4 can pull the lower end of the diagonal support rod 31 upward, so that the diagonal support rod 31 lifts the workpiece 5 out of the cooling fluid 12 for subsequent clamping / grasping; the transverse movement assembly 2 can drive the diagonal support assembly 3 to move laterally to adjust the spacing between the two pairs of transverse movement assemblies 2, so as to adapt to the overlap of workpieces 5 of different lengths.
