[0002] Mold steel material is a type of steel used to manufacture molds such as cold stamping dies, hot forging dies, and die-casting molds. Mold steel materials have different shapes. When processing mold steel materials, they need to be fixed to improve processing stability.

[0003] At present, when processing cylindrical mold steel materials, arc-shaped fixtures are usually used to position the workpiece. Because the curvature of the fixture cannot be adjusted, the fixture needs to be replaced when positioning workpieces of different specifications. The cost is too high and the operation is complicated. When the position of the fixture is frequently adjusted, it is difficult to ensure that the workpiece is always in the processing center position, and the processing accuracy of the workpiece is easily affected by position deviation. Utility Model Content

[0004] In order to overcome the above-mentioned defects, the utility model provides a fixing device for steel processing, which solves the problem that the clamp needs to be replaced during the positioning operation of workpieces of different specifications, which is too costly and complicated to operate. When the position of the clamp is frequently adjusted, it is difficult to ensure that the workpiece is always in the processing center position, and the processing accuracy of the workpiece is easily affected by position deviation.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixing device for steel processing, comprising a mounting base, a support frame is fixed on the top of the mounting base, a processing table is installed on the support frame, positioning components are respectively installed on both sides of the top of the processing table, the positioning components include a slide seat, a nut is clamped in the slide seat, an adjustment component is connected to the inner thread of the nut, and a driving component is respectively installed at one end of the two adjustment components close to each other;

[0006] The two ends of the slide seat are respectively hinged with connecting rods through pin shafts, the other end of the connecting rod is connected to a hinged rod, the end of the hinged rod away from the connecting rod is provided with a support bearing, the support bearing is clamped on the processing table, the hinged rod is connected to an extension rod through the support bearing, the end of the extension rod away from the support bearing is installed with a rotating shaft, and a positioning roller is outer-mounted on the rotating shaft.

[0008] As a further solution of the utility model: both sides of the top of the processing table are respectively provided with blanking holes, and the four corners of the processing table are respectively provided with mounting holes.

[0009] As a further solution of the utility model: a through hole is opened in the middle of the support frame, the driving assembly is installed in the through hole, and the screw rod is arranged through the through hole.

[0010] As a further solution of the utility model: the driving assembly includes a motor, the motor is installed in the through hole, a driving gear is fixed on the output shaft of the motor, two driven gears are meshed on the driving gear, and the driven gear is fixed to one end of the screw rod.

[0011] As a further solution of the utility model: a heat sink is fixed to the bottom of the motor, the heat sink is clamped in the through hole, and a plurality of heat dissipation holes are opened on the heat sink.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The fixing device for steel processing places a mold steel workpiece on a processing table, controls a driving component to drive two adjusting components to rotate, and nuts outside the adjusting components drive a slide to move. When the two slides approach each other, the slide pulls a connecting rod and drives a hinged rod to deflect, and the hinged rod drives an extension rod to rotate, and the extension rod drives a positioning roller to rotate via a rotating shaft, so that the four positioning rollers can approach the workpiece synchronously until the four positioning rollers fit the workpiece. The synchronously moving positioning rollers can correct the deviation of the workpiece, thereby achieving the purpose of calibrating the center of the workpiece, ensuring that the workpiece is at the center of the processing table, and thereby improving the processing accuracy of the workpiece.

[0014] The fixing device for steel processing controls the operation of a motor to drive a driving gear to rotate, and the driving gear drives the lead screws to rotate respectively through two driven gears. The threads outside the two lead screws have the same direction, so that the nuts outside the two lead screws can move relatively, which is convenient for synchronous adjustment of the positions of the two slides. The slide drives the positioning rollers on the extension rod to move through the connecting rod, the hinged rod and the extension rod, so that the four positioning rollers can be freely expanded or brought together, which is convenient for fixing workpieces of different specifications, abandoning the traditional method of replacing the fixture, improving the convenience of operation and reducing the cost of use.

DETAILED DESCRIPTION

[0020] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0021] like Figure 1-4 As shown, the utility model provides a technical solution: a fixing device for steel processing, comprising a mounting base 1, a support frame 2 is fixed on the top of the mounting base 1, a through hole 7 is opened in the middle of the support frame 2, a driving component 8 is installed in the through hole 7, and a screw rod 601 is arranged through the through hole 7;

[0022] A processing table 3 is installed on the support frame 2. Both sides of the top of the processing table 3 are respectively provided with drop holes, and four corners of the processing table 3 are respectively provided with mounting holes. Due to the drop holes, some of the debris generated during processing will fall through the drop holes to prevent the debris from accumulating on the processing table 3.

[0023] Positioning components 4 are respectively installed on both sides of the top of the processing table 3, and the positioning component 4 includes a slide seat 401, a nut 5 is clamped in the slide seat 401, and an adjustment component 6 is connected to the inner thread of the nut 5. The adjustment component 6 includes a screw rod 601, and the screw rod 601 passes through the support frame 2. A bearing seat 602 is provided at one end of the screw rod 601 away from the driving component 8, and the bearing seat 602 is fixed under the processing table 3. Because the bearing seat 602 is provided, the bearing seat 602 can support the screw rod 601, thereby improving the rotation stability of the screw rod 601;

[0024] The driving components 8 are respectively installed at the ends of the two adjustment components 6 close to each other. The driving components 8 include a motor 801, which is installed in the through hole 7. A driving gear 802 is fixed on the output shaft of the motor 801. Two driven gears 803 are meshed on the driving gear 802. The driven gear 803 is fixed to one end of the screw rod 601. Through the mutual cooperation between the driving gear 802 and the driven gear 803, the driving gear 802 rotates the two screw rods 601 respectively through the two driven gears 803, which facilitates the synchronous adjustment of the nuts 5 and the slide seat 401 outside the two screw rods 601.

[0025] A heat sink 804 is fixed to the bottom of the motor 801, and the heat sink 804 is snapped into the through hole 7. A plurality of heat dissipation holes are provided on the heat sink 804. Due to the heat sink 804, the heat generated by the motor 801 during operation will be discharged through the heat dissipation holes on the heat sink 804, thereby improving the heat dissipation effect of the motor 801 and maintaining its long-term stable operation.

[0026] The two ends of the slide 401 are respectively hinged with a connecting rod 402 through a pin shaft, and the other end of the connecting rod 402 is connected to a hinged rod 403. The end of the hinged rod 403 away from the connecting rod 402 is provided with a support bearing 407, and the support bearing 407 is clamped on the processing table 3. The hinged rod 403 is connected to an extension rod 404 through the support bearing 407. The end of the extension rod 404 away from the support bearing 407 is installed with a rotating shaft 405, and a positioning roller 406 is connected to the outer sleeve of the rotating shaft 405.

[0027] The working principle of the utility model is:

[0028] When in use, place the mold steel workpiece on the processing table 3, control the motor 801 to work, so that the output shaft of the motor 801 drives the two driven gears 803 to rotate through the active gear 802, and the two driven gears 803 respectively drive the two screw rods 601 to rotate. The threads on the outside of the two screw rods 601 have the same direction, so that the nuts 5 on the outside of the two screw rods 601 can move relatively, and the two nuts 5 respectively drive the two slides 401 to approach each other, and the slide 401 will pull the connecting rod 402 and drive the hinge rod 403 to deflect, and the hinge rod 403 drives the extension rod 404 to rotate, and the extension rod 404 drives the positioning roller 406 to rotate through the rotating shaft 405, so that the four positioning rollers 406 can synchronously approach the workpiece until the four positioning rollers 406 are tightly fitted with the workpiece, and the workpiece can be fixed. When removing the workpiece, control the motor 801 to rotate in the opposite direction. Similarly, the four positioning rollers 406 can be unfolded and separated from the workpiece, and it can be removed.

[0029] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0030] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
