Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a flattening device for mechanically processed parts. Background Art

[0002] Machining refers to the process of changing the external dimensions or performance of a workpiece through a mechanical device. It can be divided into cutting and pressure processing according to the difference in processing methods. When there are burrs and uneven protrusions on the surface of the workpiece, mechanical processing is more necessary to grind its surface and smooth the surface of the workpiece through mechanical processing, thereby improving the accuracy and surface roughness of the workpiece.

[0003] However, existing leveling processing devices for machined parts, such as the one disclosed in announcement number CN219234910U, can only move in the vertical direction during the leveling of the machined parts, which makes the contact area of the grinding mechanism very limited, and easily creates blind spots that the grinding parts cannot reach. If you want to increase the grinding area, you can only do it through repeated tension adjustment, which is not only inefficient but also difficult to ensure the position stability of the workpiece to be ground. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of insufficient flatness of flattening devices for machined parts in the prior art, and to propose a flattening device for machined parts.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0008] The lateral swing mechanism also includes a supporting cross bar fixedly installed in the box body, and a limiting ring is fixedly installed on the end of the supporting cross bar. A lateral sliding rod fixedly connected to the lateral swing rack is slidably sleeved in the limiting ring. A rack meshing with the half gear is provided on the lateral sliding rod, and a clamping tool for fixing the mechanical workpiece to be processed is provided on the lateral swing rack.

[0010] Preferably, the limiting round rod is slidably fitted into a through hole on the horizontal storage rack.

[0011] Preferably, the grinding mechanism includes a second drive motor fixedly mounted on the box body, a ball screw is fixedly connected to the output end of the second drive motor, and the ball screw is rotatably connected to the box body, a movable nut fixedly connected to the drive cylinder is slidably sleeved on the ball screw, second limit rods are symmetrically arranged on both sides of the movable nut, and a limit groove corresponding to the second limit rod is provided on the box body.

[0012] Preferably, a sliding limiting block connected to the second limiting rod is provided in the limiting groove.

[0013] Compared with the prior art, the present invention has the following advantages:

[0014] 1.

A first driving motor is arranged outside the box, and the first driving motor is used to drive the deflection disc to rotate, and the deflection disc drives the traction bolt to rotate, thereby driving the deflection rod to deflect around the first limiting rod. While the deflection rod is deflecting, the engagement between the half gear and the rack is used to drive the horizontal sliding rod to swing horizontally. The swing of the horizontal sliding rod drives the horizontal swing rack to swing horizontally left and right, thereby realizing the horizontal movement of the mechanical workpiece to be processed clamped on the horizontal swing rack.

[0015] 2. The utility model sets a second drive motor, which drives the ball screw to rotate and drives the movable nut to move back and forth in the front and back directions. A drive cylinder is set under the movable nut, and the drive cylinder drives the upper and lower positions of the grinder to achieve smooth grinding of the machined parts.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-Figure 5 A flattening device for machined parts comprises a hollow box 1 with operation ports 2 on both sides.

[0024] A traverse rack 3 for placing workpieces to be machined is movably provided in the box body 1, and a traverse mechanism for driving the traverse rack 3 to move back and forth in the left and right directions is provided in the box body 1. The traverse mechanism includes a first drive motor 7 fixedly connected to the box body 1 for driving the traverse mechanism to traverse back and forth. The output end of the first drive motor 7 is fixedly connected to a deflection disc 8, and an eccentrically arranged traction bolt 9 is fixedly installed on the deflection disc 8. When the first drive motor 7 is started, the output end of the first drive motor 7 will drive the deflection disc 8 to rotate, and the rotation of the deflection disc 8 will drive the traction bolt 9 to rotate. A first limiting rod 11 is fixedly installed in the box body 1, and a deflection rod 10 with a sliding sleeve traction bolt 9 is rotatably installed on the first limiting rod 11. A half gear 12 is fixedly installed on the deflection rod 10, so when the traction bolt 9 rotates, it will drive the deflection rod 10 to deflect and swing around the first limiting rod 11, and the half gear 12 below the deflection rod 10 will also deflect and swing accordingly;

[0025] The sway mechanism also includes a supporting cross bar 13 fixedly installed in the box body 1, and a limiting ring 14 is fixedly installed on the end of the supporting cross bar 13. A slidable sleeve is provided with a lateral sliding rod 15 fixedly connected to the sway rack 3 in the limiting ring 14. The sway rack 15 can slide in the limiting ring 14. A rack 16 meshing with the half gear 12 is provided on the lateral sliding rod 15. When the half gear 12 deflects and swings, it will mesh with the rack 16 on the lateral sliding rod 15 and drive the lateral sliding rod 15 to swing horizontally left and right. The sway rack 3 is fixedly connected to the sway rack 3. When the sway sliding rod 15 swings horizontally left and right, it will drive the sway rack 3 and that row to swing horizontally left and right. The sway rack 3 is provided with a clamping tooling for fixing the mechanical workpiece to be processed.

[0026] When the clamping plate 5 moves, the limiting rods 6 on the left and right sides will slide into the through holes, thereby limiting the position of the clamping plate 5 and maintaining the stability of the clamping plate 5.

[0027] A driving cylinder 23 is movably provided in the box body 1, and a grinding mechanism for driving the cylinder 23 to move back and forth is provided in the box body 1. The grinding mechanism includes a second driving motor 17 fixedly mounted on the box body 1. A ball screw 18 is fixedly connected to the output end of the second driving motor 17, and the ball screw 18 is rotatably connected to the box body 1. When the second driving motor 17 rotates, the output end will drive the ball screw 18 to rotate. A moving nut 19 fixedly connected to the driving cylinder 23 is slidably sleeved on the ball screw 18. When the ball screw 18 rotates, the moving nut 19 is subjected to the rotation of the ball screw 18 and will move in the front-back direction on the ball screw 18. Second limiting rods 20 are symmetrically provided on both sides of the moving nut 19, and a limiting groove 21 corresponding to the second limiting rod 20 is provided on the box body 1. A sliding limiting block 22 connected to the second limiting rod 20 is provided in the limiting groove 21. Therefore, when the moving nut 19 moves forward and backward, the second limiting rod 20 will drive the sliding limiting block 22 to slide in the limiting groove 21, forming a limit for the moving nut 19, thereby maintaining the stability of the moving nut 19 during the forward and backward movement;

[0028] The grinding mechanism includes a grinder 24 fixedly mounted on the output end of the driving cylinder 23, and the driving cylinder 23 is fixedly connected to the movable nut 19, so when the movable nut 19 moves back and forth, it will drive the driving cylinder 23 to move accordingly. At the same time, when the driving cylinder 23 moves, the grinder 24 fixedly connected to the lower end of the driving cylinder 23 will grind the mechanical workpiece to be processed.

[0029] It should be noted that the specific models and specifications of the motors and cylinders need to be selected and determined based on the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0030] The functional principle of this utility model can be explained through the following operation modes:

[0031] Place the workpiece to be machined into the horizontal rack 3, and tighten the limit bolts 4 on both sides. The limit bolts 4 drive the clamping plates 5 to clamp and fix the workpiece to be machined;

[0032] Start the first drive motor 7. The output end of the first drive motor 7 drives the deflection disc 8 to rotate. The deflection disc 8 drives the traction bolt 9 to rotate. When the traction bolt 9 rotates, the deflection rod 10 is driven to deflect around the first limit rod 11.

[0033] The deflection rod 10 will drive the half gear 12 to deflect synchronously while deflecting. The deflection of the half gear 12 will drive the transverse sliding rod 15 to swing transversely. The swing of the transverse sliding rod 15 will drive the transverse swing rack 3 to swing transversely. The transverse swing of the transverse swing rack 3 will drive the workpiece to be processed to move horizontally left and right.

[0034] The second drive motor 17 is started, and the output end of the second drive motor 17 drives the ball screw 18 to rotate. When the ball screw 18 rotates, it drives the movable nut 19 to move in the front-back direction.

[0035] The output end of the driving cylinder 23 will drive the grinder 24 to adjust its height to ensure that the grinder 24 is in contact with the mechanical workpiece to be processed, thereby achieving grinding processing of the mechanical workpiece to be processed.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
