Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 As shown, a machining fixture auxiliary fixing device includes a worktable 1 and a PLC controller disposed on the worktable 1. The surface of the worktable 1 is provided with support legs 2 for support, and a support frame 3 is fixed on the surface of the worktable 1. Side frames 4 are fixed on both sides of the surface of the worktable 1. Electric push rods 5 are fixed on the surface of the side frames 4. A rotating mechanism 6 for rotation is provided on the surface of the support frame 3. An extension mechanism 7 that works in conjunction with the rotating mechanism 6 is provided on the surface of the electric push rod 5. A clamping block 8 is bolted to the surface of the rotating mechanism 6, and a connecting piece 9 is fixed to the surface of the clamping block 8.

[0021] In use, the operator can use the electric push rod 5 to drive the extension mechanism 7 to move the clamping block 8, thereby clamping the target workpiece under the action of the clamping blocks 8 on both sides. In addition, under the action of the rotating mechanism 6, different target workpieces can be selected. Furthermore, through the setting of the connecting piece 9, the operator can place commonly used clamping pieces on the surface of this device. When necessary, the clamping block 8 can also be replaced, further improving the applicability of this device.

[0022] The rotating mechanism 6 includes a motor 61 fixed to the surface of the support frame 3. The output shaft of the motor 61 is fixed with a drive gear 62. Driven gears 63 are fixed on both sides of the surface of the drive gear 62. Rotating blocks 64 are fixed on the surface of the driven gears 63. The rotating blocks 64 rotate on both sides of the surface of the worktable 1. In this embodiment, through the arrangement of the motor 61, drive gear 62, driven gears 63 and rotating blocks 64, the drive gear 62 and driven gear 63 mesh under the action of the motor 61, and the rotating blocks 64 can rotate under the action of the driven gears 63.

[0023] It is worth noting that, since the driven gears 63 and the driving gears 62 on both sides mesh, the rotating blocks 64 on both sides rotate in different directions. Therefore, when setting the clamping block 8 and the connecting piece 9, the same connecting pieces 9 need to be set in an offset manner to achieve the purpose of working together.

[0024] Motor 61 is a servo motor and has a built-in brake device. In this embodiment, this setting improves the accuracy of motor 61 rotation and, under the action of the brake device, allows the rotating block 64 to stop stably at a specified angle.

[0025] Both driven gears 63 and both rotating blocks 64 have the same specifications. In this embodiment, this arrangement improves the stability of the driven gears 63 and rotating blocks 64 during operation and enhances the coordination of their rotation.

[0026] The extension mechanism 7 includes a first contact block 71, a second contact block 72, a connecting plate 73, a slide rod 74, a spring 75, and a slide groove 76. The first contact block 71 is fixed to one side of the actuating end of the two electric push rods 5. There are several second contact blocks 72, each sliding on the surface of the rotating block 64. The connecting plate 73 is fixed to one side of the surface of the second contact block 72. The slide rod 74 is fixed to both sides of the surface of the connecting plate 73 and slides in the inner cavity of the rotating block 64. One end of the spring 75 is fixed to the surface of the connecting plate 73, and the other end of the spring 75 is fixed to the surface of the rotating block 64. The slide groove 76 is formed in the rotating block 64. On the surface of the rotating block 64, the sliding rod 74 and the sliding groove 76 work together. In this embodiment, through the arrangement of the first bonding block 71, the second bonding block 72, the connecting plate 73, the sliding rod 74, the spring 75 and the sliding groove 76, when the electric push rod 5 drives the first bonding block 71 to move, the connecting plate 73 can drive the clamping block 8 and the connecting piece 9 to move under the action of the mutual bonding of the first bonding block 71 and the second bonding block 72. Thus, the target part is clamped under the action of the clamping blocks 8 on both sides. In addition, the stability of the connecting plate 73 when sliding is improved under the action of the sliding rod 74 and the spring 75.

[0027] Both the first bonding block 71 and the second bonding block 72 are inclined, and the inclination angles are matched with each other. In this embodiment, this setting improves the smoothness of the first bonding block 71 and the second bonding block 72 when they are bonded together, thereby improving the practicality of the device.

[0028] Working principle: During machining, the operator can place the target workpiece on the surface of the worktable 1 and use the electric push rod 5. Driven by the electric push rod 5, the first bonding block 71 and the second bonding block 72 are bonded together. Then, with the assistance of the connecting plate 73 and the slide rod 74, the clamping blocks 8 on both sides clamp the target workpiece. The clamping blocks 8 in this application are all different. If it is necessary to clamp target workpieces of different shapes, the operator can use the motor 61. Under the action of the motor 61, the driving gear 62 and the driven gear 63 are meshed, which causes the rotating blocks 64 on both sides to rotate. This causes the rotating blocks 64 on both sides to drive the clamping blocks 8 to rotate. After the clamping blocks 8 rotate, the appropriate clamping block 8 can be used for the target workpiece of this work, thereby improving the applicability of this device.
