Description

Technical Field

[0001] This utility model discloses a cutting device for processing fixed seats, which relates to the technical field of rotary fixed seat cutting equipment. Background Technology

[0002] Cutting fixture parts typically involves precisely cutting material into specific shapes and sizes for use in fixture assembly or further processing. Mechanical cutting often employs band saws and circular saws for straight-line cutting, which is highly efficient. During cutting, the workpiece needs to be secured to ensure stability and avoid cutting errors, facilitating assembly or further processing of the fixture after production.

[0003] Precise cutting is crucial in the processing of fixed seats, as it directly affects the quality of the finished fixed seats. In the traditional mechanical cutting process of fixed seats, the cutting efficiency of a single station is low, and the fixed seat is not securely clamped during cutting, which can easily cause it to shift. This can result in the size and shape of the cut fixed seat not meeting the usage requirements, making it a waste part. Therefore, it is necessary to provide a cutting device for processing fixed seats to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a cutting device for processing fixed seats, which can achieve the effect of dual-station processing of fixed seats with high processing accuracy.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cutting device for processing fixed seats, comprising a frame, characterized in that: a motion mechanism is mounted on the frame, a cutting mechanism is mounted on the motion mechanism, a clamping mechanism is mounted on the frame, and a central frame is mounted at the center of the frame; the clamping mechanism includes a slide rail, a transmission frame is slidably mounted on the slide rail, a transmission rod is mounted at the rear end of the transmission frame, a positioning shaft is mounted on the clamping mechanism, an abutment frame is rotatably mounted on the positioning shaft, a gripper is rotatably mounted on the positioning shaft, the gripper is rotatably connected to the abutment frame, and an abutment head is mounted at the center of the transmission frame for abutting against the outer wall of the workpiece of the fixed seat.

[0006] Preferably, the contact frame is symmetrically arranged in two sets with the contact head as the center, the positioning shaft is symmetrically arranged in two sets with the contact head as the center, and the gripper is symmetrically arranged in two sets with the contact head as the center.

[0007] Preferably, an abutment wheel is rotatably mounted on the top of the gripper, and several sets of gripping wheels are rotatably mounted on the inner side of the gripper, with anti-slip pads provided on the gripping wheels.

[0008] Preferably, a torsion spring is provided at the connection between the gripper and the contact frame.

[0009] Preferably, a protective shell is installed above the positioning pivot, and the protective shell is fixedly connected to the slide rail.

[0010] Preferably, the cutting mechanism is provided with two sets of circular saws, and the clamping mechanism is provided with two sets symmetrically distributed around the central frame.

[0011] Preferably, the transmission rod is driven by a motor.

[0012] Preferably, the transmission frame is trapezoidal in shape, the contact frame is slidably connected to the side of the transmission frame, and a circular block is provided at the connection between the contact frame and the transmission frame.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: The cutting device drives the transmission rod forward through the motor in the clamping mechanism, so that the transmission frame moves forward in a straight line along the direction limited by the slide rail, thereby pushing the contact frame to drive the two sets of grippers to move towards the center to clamp the positioning and fixing seat workpiece. At the same time, the contact head pushes the fixing seat workpiece to be close to the central frame. The two clamp each other to fix the radial position of the fixing seat workpiece, thereby realizing the center positioning and clamping of fixing seat workpieces of different sizes during cutting. In this device, the two sets of circular saws correspond to two sets of clamping mechanisms symmetrically distributed with the central frame as the center, so that two sets of fixing seat workpieces can be cut simultaneously in the same working time, realizing dual-station simultaneous operation.

[0018] 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.

[0019] Specific implementation examples:

[0020] like Figure 1As shown, a cutting device for processing fixed seats includes a frame 1, a motion mechanism 2 mounted on the frame 1, a cutting mechanism 3 mounted on the motion mechanism 2, a clamping mechanism 4 mounted on the frame 1, and a central frame 5 mounted at the center of the frame 1.

[0021] The function of the motion mechanism 2 is to drive the cutting mechanism 3 to move upward and forward along two axes. Its working method is existing technology and will not be described in detail here.

[0022] The overall movement process of the cutting device is as follows: the operator puts the fixed seat workpiece into the clamping mechanism 4, and the clamping mechanism 4 positions and clamps the fixed seat workpiece. Then, the motion mechanism 2 drives the cutting mechanism 3 to mechanically cut the fixed seat workpiece. The circular saw in the cutting mechanism 3 can be manually adjusted in terms of spacing to determine the required size of the fixed seat workpiece to be cut.

[0023] like Figure 2 As shown, the clamping mechanism 4 includes a slide rail 41, on which a transmission frame 42 is slidably mounted. A transmission rod 43 is mounted at the rear end of the transmission frame 42. The transmission rod 43 is driven by a motor. A positioning shaft 48 is mounted on the clamping mechanism 4. An abutment frame 44 is rotatably mounted on the positioning shaft 48. A gripper 45 is rotatably mounted on the positioning shaft 48. The gripper 45 is rotatably connected to the abutment frame 44. An abutment head 46 is mounted at the center of the transmission frame 42 to abut against the outer wall of the workpiece. The transmission frame 42 is trapezoidal in shape. The abutment frame 44 is slidably connected to the side of the transmission frame 42. A circular block (not shown in the figure) is provided at the connection between the abutment frame 44 and the transmission frame 42.

[0024] When the clamping mechanism 4 is running, the positioning shaft 48 is fixed in the sliding position, and the motor drives the transmission rod 43 to move forward, so that the transmission frame 42 moves forward in a straight line along the direction limited by the slide rail 41. The contact head 46 contacts the side of the fixed seat workpiece, pushing the fixed seat workpiece forward until the other side of the fixed seat contacts the side of the central frame 5. At the same time, the forward movement of the transmission frame 42 causes the circular block at the end of the contact frame 44 to tilt outward along the side of the trapezoidal block-shaped transmission frame 42 with the positioning shaft 48 as the center, driving the gripper 45 to tilt inward and clamp onto the outside of the fixed seat workpiece, thereby clamping the fixed seat workpiece.

[0025] The contact frame 44 is symmetrically arranged in two sets with the contact head 46 as the center; the positioning rotating shaft 48 is symmetrically arranged in two sets with the contact head 46 as the center; and the gripper 45 is symmetrically arranged in two sets with the contact head 46 as the center.

[0026] The symmetrically arranged abutment frame 44, positioning shaft 48 and gripper 45 can move simultaneously under the action of transmission frame 42, thereby achieving the effect of center positioning of the workpiece on the fixed seat during clamping.

[0027] The top of the gripper 45 is rotatably mounted with an abutment wheel 451, and several sets of gripping wheels 452 are rotatably mounted on the inner side of the gripper 45. The gripping wheels 452 are provided with anti-slip rubber pads (not shown in the figure).

[0028] The setting of the abutting wheel 451 allows the gripper 45 to rotate along the side shape of the workpiece on the fixed seat. Then the clamping wheel 452 clamps the outside of the workpiece on the fixed seat. The setting of the anti-slip rubber pad increases the clamping friction during clamping, so that the clamping can be stable.

[0029] A torsion spring (not shown in the figure) is provided at the connection between the gripper 45 and the contact frame 44;

[0030] The torsion spring allows the gripper 45 to adaptively clamp the outer wall of the workpiece on the fixed seat, making the internal structure of the mechanism more stable. At the same time, the torque of the torsion spring can increase the clamping force. When the transmission frame 42 retracts from the transmission rod 43 after clamping, the gripper 45 can quickly return to its original position and exit the clamping.

[0031] A protective shell 47 is installed above the positioning pivot 48, and the protective shell 47 is fixedly connected to the slide rail 41;

[0032] The protective shell 47 is used to protect the internal structure of the clamping mechanism 4, ensuring its stability and preventing waste chips from entering the mechanism during processing and causing damage to the clamping mechanism 4.

[0033] The cutting mechanism 3 is provided with two sets of circular saws, and the clamping mechanism 4 is provided with two sets and is symmetrically distributed with the central frame 5 as the center.

[0034] The two sets of circular saws correspond to two sets of clamping mechanisms 4 symmetrically distributed around the central frame 5, so that two sets of fixed seat workpieces can be cut simultaneously in the same working time, realizing dual-station simultaneous operation.

[0035] In summary, the cutting device uses a motor-driven transmission rod 43 in the clamping mechanism 4 to move forward, causing the transmission frame 42 to move linearly forward along the direction limited by the slide rail 41. This pushes the contact frame 44 to move the two sets of grippers 45 towards the center to clamp the positioning and fixing workpiece. At the same time, the contact head 46 pushes the fixing workpiece to come into contact with the central frame 5. The two clamp each other to fix the radial position of the fixing workpiece, thereby achieving the center positioning and clamping of fixing workpieces of different sizes during cutting. In this device, the two sets of circular saws correspond to two sets of clamping mechanisms 4 symmetrically distributed around the central frame 5, so that two sets of fixing workpieces can be cut simultaneously in the same working time, realizing dual-station simultaneous operation.

[0036] The above description is merely a preferred embodiment of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions within this concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should also be considered within the scope of protection of this application.
