[0002] Customers of the guide pillar part of the mold accessories usually require the end face of the accessory support part to have a high hardness to ensure that the end face is not easily damaged by knocking. Therefore, it is necessary to perform high-frequency quenching treatment on the end face of the support part of the workpiece. The traditional method for quenching the end face of the workpiece is: relying on the operator to hold the workpiece by hand and rotate the workpiece manually for end face heating. When mass production is required, due to the fact that the operator holds the workpiece and rotates it for heating by hand, the labor intensity is relatively high. In addition, due to factors such as high labor intensity and easy fatigue. Especially when performing high-frequency quenching treatment on large workpieces, it is more likely to appear defective products. Content of the Utility Model

BRIEF DESCRIPTION OF THE DRAWINGS
[0013] Figure 1 It is a schematic structural diagram of the present utility model. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0014] The present utility model is developed to reduce the labor intensity of workers, improve the production efficiency of high-frequency heating of the workpiece end face, and enhance the competitiveness of products in the market. The following further elaborates on the present utility model with reference to the drawings and embodiments.
[0015] As Figure 1 shown, the present utility model includes a first fixing seat 1 and a second fixing seat 4, a spacing adjustment structure for adjusting the spacing between the first fixing seat 1 and the second fixing seat 4, a first workpiece support and rotation structure 11 provided on the first fixing seat 1, and a second workpiece support and rotation structure 7 provided on the second fixing seat 4. The first workpiece support and rotation structure 11 and the second workpiece support and rotation structure 7 cooperate to support the workpiece, and the workpiece 10 is rotatably connected to the first workpiece support and rotation structure 11 and the second workpiece support and rotation structure 7.
[0016] By adopting the first workpiece support and rotation structure and the second workpiece support and rotation structure to support the workpiece, the labor intensity of workers is greatly reduced. Moreover, when the worker rotates the workpiece for end face 101 heating, it will be smoother, with good actual use effect, simple operation and relatively high processing efficiency.
[0017] Preferably, both the first workpiece support and rotation structure 11 and the second workpiece support and rotation structure 7 in this example adopt a bearing group composed of two bearings in a cooperation and limiting manner.
[0018] The first workpiece support and rotation structure 11 includes a first bearing and a second bearing arranged in parallel. The first bearing and the second bearing are fixed to one side of the first fixed seat 1 through a bearing fixing core seat 12. One end of the workpiece 10 is placed on the limiting groove 8 in front of the first bearing and the second bearing. The second workpiece support and rotation structure 7 includes a third bearing and a fourth bearing arranged in parallel. The third bearing and the fourth bearing are fixed to one side of the second fixed seat 4 through a bearing fixing core seat 12. The other end of the workpiece 10 is placed on the limiting groove 8 in front of the third bearing and the fourth bearing.
[0019] The first fixed seat 1 and the second fixed seat 4 are respectively provided with mounting hole positions for fixing the bearing fixing core seat 12 and locking holes communicated with the mounting hole positions. Core shaft locking screws 13, 6 are arranged in the locking holes. During installation, the core shaft locking screws 13, 6 are tightened to abut against the bearing fixing core seat 12, thereby fixing the bearing fixing core seat 12 on the first fixed seat 1 and the second fixed seat 4.
[0020] The four bearings in this example are symmetrically arranged in pairs on the first fixed seat 1 and the second fixed seat 4. To reduce the installation difficulty of the first bearing, the second bearing, the third bearing and the fourth bearing and avoid interference between the first bearing, the second bearing, the third bearing and the fourth bearing and the first fixed seat 1 and the second fixed seat 4 when supporting the workpiece 10, an avoidance groove 9 is further provided on the upper surfaces of the first fixed seat 1 and the second fixed seat 4, and the position of the avoidance groove 9 corresponds to that of the limiting groove 8.
[0021] When the workpiece 10 is rotated, the first bearing, the second bearing, the third bearing and the fourth bearing also rotate accordingly, reducing the friction between the jig and the workpiece 10, making the rotation of the workpiece 10 smoother and effectively improving the working efficiency.
[0022] Preferably, during the use of this example, the position of the first fixed seat 1 is fixed relative to the distance from the heating device. To achieve the consistency of the machining of the end face 101 of the workpiece 10, this example is also provided with a sensor for limiting the placement position of the workpiece 10, so that the position of the end face 101 relative to the heating device is controllable.
[0023] As an embodiment of the present utility model, in this example, the spacing adjustment structure respectively penetrates through the optical axes 3 disposed on the first fixed seat 1 and the second fixed seat 4. The first fixed seat 1 and the second fixed seat 4 are respectively provided with mounting holes for fixing the optical axes and locking holes communicated with the mounting holes. Optical axis locking screws 2 and 5 are provided in the locking holes. During installation, tighten the optical axis locking screws 2 and 5 so that they abut against the optical axis 12, thereby locking the optical axis in the mounting holes of the first fixed seat 1 and the second fixed seat 4. When the spacing needs to be adjusted, only need to loosen the optical axis locking screw 5 on the second fixed seat 4 to release the limit on the optical axis 3, and then it is convenient to adjust the spacing of the second fixed seat 4 relative to the first fixed seat 1 along the optical axis 3.
[0024] As another embodiment of the present utility model, the spacing adjustment structure is a slide rail and other structures disposed below the first fixed seat and the second fixed seat.
[0025] The working principle of the present utility model is as follows:
[0026] During operation, the operator places the workpiece 10 between two bearing groups, adjusts its distance from the inductor, and after setting the corresponding parameters, can manually and easily rotate the workpiece to perform high-frequency heating on its end face.
[0027] If different workpiece lengths need to be adapted, the second fixed seat 4 can be adjusted in position according to the workpiece length.
[0028] From the above description, it can be seen that the traditional end face heating of workpieces mainly relies on the method of manually rotating the workpiece by the operator to perform end face heating. Rotating the workpiece is not smooth enough, relying on the operator's own experience, affected by human factors, and the work efficiency is relatively low. The high-frequency quenching fixture for the end face of this workpiece is simple and convenient to operate, greatly reducing the labor intensity of workers, and has the advantages of simple structure, strong practicability, and low cost. Since this fixture places the workpiece between two pairs of bearings, it is easier and smoother to manually rotate the workpiece. The high-frequency quenching fixture for the end face of this workpiece has a reasonable structure, low cost, easy and simple operation, and good actual use effect.
[0029] The above-described specific embodiments are the preferred embodiments of the present utility model, and do not limit the specific implementation scope of the present utility model. The scope of the present utility model includes but is not limited to this specific embodiment. All equivalent changes made in accordance with the present utility model are within the protection scope of the present utility model.
