Description

Technical Field

[0001] The utility model relates to a device for adjusting the axial end play of a guide roll, and belongs to the technical field of guide roll production equipment. Background Art

[0002] The KOCKS rolling mill has relatively high rolling accuracy, and the corresponding requirements for the axial end play of the guide roll it is equipped with are also increased. When adjusting the axial end play of the guide roll at present, it is necessary to first install the guide roll into the guide guard, and then use a dial indicator with a universal magnetic base to measure its axial end play. According to the measured axial end play, gaskets with appropriate thickness are inserted into the guide roll to adjust the axial end play of the guide roll within the qualified range. The process is relatively cumbersome and there will be a large difference between the measured axial end play of the guide roll and the actual axial end play due to the axial displacement of the guide roll support arm. The need to speed up the adjustment of the axial end play of the guide roll and improve the adjustment accuracy is very urgent. Content of the Utility Model

[0017] Refer to Figure 1 - Figure 2As shown in the figure, the technical solution adopted in this specific embodiment is as follows: It includes a vise 1, a universal shaft 2, and a dial indicator 3. One end of the universal shaft 2 is fixed to one side of the vise 1, and the other end of the universal shaft 2 is connected to the dial indicator 3. The dial indicator 3 is located at the central axis position of the vise 1 and abuts against the axis of the main shaft 6. In this embodiment, the dial indicator is the main tool for measuring the endplay. The traditional measurement method is to install the pre-installed guide roller in the guide guard for measurement, and both the disassembly and assembly are rather troublesome. Therefore, in this embodiment, a vise is used to fix the guide roller. At the same time, a universal shaft is provided on the vise, and the dial indicator is connected through the universal shaft. According to the position of the guide roller after fixation, the position of the dial indicator is adjusted to ensure that it abuts against the main shaft pre-installed in the guide roller. At this time, the dial indicator will obtain an initial data. During measurement, the main shaft is pushed forward and backward, and the data of the dial indicator will change. Combining the initial data, the endplay can be obtained. Observe whether it is controlled between 0.01 - 0.06 mm. If it is not within the qualified value range, place a gasket in the guide roller and measure again until the endplay is between 0.01 - 0.06 mm. Since the guide roller is fixed to the vise, it can be disassembled and assembled conveniently, and using the universal shaft to fix the dial indicator can conveniently adjust the fixed position of the dial indicator, thus effectively improving the measurement efficiency of the endplay of the guide roller.

[0018] More specifically, the front end of the dial indicator 3 is a thimble 31, and the thimble 31 abuts against the axis of the main shaft 6. An elastic thimble is provided at the front end of the dial indicator, and the thimble abuts against the axis position of the main shaft. During measurement, it is necessary to make the thimble be pressed by the main shaft to obtain an initial data. When the main shaft is pushed from both sides, the thimble is further pressed or released, generating two new measurement data. Combining the initial data, the specific actual endplay can be calculated.

[0019] More specifically, the universal shaft 2 is of a three-section structure. The front end of the first section of the shaft is movably arranged on the side wall of the vise 1, and the two sections of the shaft are connected by a ball head that can be tightened. The end of the second section of the shaft is provided with a ball head that can be tightened to connect to the third section of the shaft, and the third section of the shaft is then connected to the dial indicator 3. In this embodiment, a universal shaft of a three-section structure is adopted, and the ends of each section of the shaft are connected and fixed by ball heads that can be tightened. The front end of the first shaft is movably arranged on the side wall of the vise. After adjusting the position of the first section of the shaft, lock the front ball head, and the first section of the shaft can no longer move. Then adjust the angle between the two sections of the shaft to move the dial indicator to the axis position of the main shaft and lock the ball head between the two sections of the shaft. At this time, the second section of the shaft can no longer move. When the thimble of the dial indicator abuts against the axis of the main shaft, lock the ball head on the third section of the shaft, and the fixation of the dial indicator is completed. The overall structure is simple and easy to use, and can quickly position and fix the dial indicator, thus realizing the rapid measurement of the endplay.

[0020] More specifically, the flat-jaw vice 1 includes a clamping block 11, a tail plate 12, and a base 14. The clamping block 11 is slidably disposed on the base 14. The tail plate 12 is disposed at the end of the base 14 and is an integral structure with the base 14. A clamping cavity 13 is formed between the clamping block 11 and the tail plate 12. The front end of the base 14 is a fixed plate, and a rocker 4 is disposed on the fixed plate. The rocker 4 is a screw threadedly engaged with the fixed plate at the front end of the base 14. The rocker 4 passes through the fixed plate and is fixedly connected to the clamping block 11. In this embodiment, the guide roller is placed in the clamping cavity. Rotating the rocker to push the clamping block forward to clamp the guide roller. By using the flat-jaw vice, the guide roller can be quickly fixed and disassembled, so that the end play can be quickly adjusted, reducing the working intensity of the pre-installation of the guide guard, improving the guiding accuracy and rolling accuracy of the guide guard, and reducing the incidence of production accidents.

[0021] More specifically, anti-slip pads are provided on the inner walls of the opposite sides of the tail plate 12 and the base 14. The anti-slip pads can not only increase the stability when the guide roller is fixed, but also prevent scratches on the surface of the guide roller.

[0022] The working principle of the present invention: Install the bearing into the guide roller 5, cover the dust cover, install the main shaft 6, sleeved the sleeve on the threaded end of the main shaft, screw the nut onto the thread of the main shaft and tighten it with a wrench. Rotate the guide roller 5 and the main shaft 6 clockwise and counterclockwise for several turns respectively, and then gently tap the main shaft 6 axially on both sides of the main shaft 6 with a hammer, so that the subsequent measurement of the axial end play of the guide roller 5 can be more accurate. Clamp the installed guide roller 5 with the flat-jaw vice 3 (the dust cover should not be clamped). Push the main shaft 6 axially back and forth on both sides of the main shaft 6. According to the change of the dial indicator reading, calculate the axial end play of the guide roller 5; disassemble the guide roller 5, insert a gasket with a suitable thickness into the guide roller 5 according to the measured axial end play, and then assemble the guide roller 5. Measure the axial end play again to observe whether it is controlled within 0.01 - 0.06 mm. If the axial end play is not within this range, the thickness of the inserted gasket needs to be readjusted. In this way, the guide roller 5 can be quickly disassembled and assembled and the axial end play can be measured, and the axial end play can be quickly adjusted.

[0023] The above is only used to illustrate the technical solution of the present invention and not to limit it. Any other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention should be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
