Description

Technical Field

[0001] This utility model relates to the field of piston ring fixing technology, and in particular to a fixing fixture for piston ring processing. Background Technology

[0002] In the manufacturing process of piston rings, the fixture, as a core auxiliary equipment, directly determines the machining accuracy, production efficiency, and finished product qualification rate of the piston rings. With the continuous improvement of piston ring performance requirements in the internal combustion engine industry, the structural design of piston rings is becoming increasingly complex, and their dimensions and specifications are showing a trend towards diversification. This poses greater challenges to the adaptability, stability, and ease of adjustment of the fixture.

[0003] Chinese patent CN222843239U discloses a fixing fixture for piston ring processing. The device can clamp the piston ring through a limiting component, thereby achieving the piston ring positioning effect. The fixing component is used to press the piston ring. The device has a simple structure and is easy to operate. However, the limiting component can only clamp the piston ring from both sides, and the clamping points are limited. Although it can clamp objects of various sizes, it is prone to loosening during the cutting process. Therefore, a fixing fixture for piston ring processing is proposed. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fixed fixture for piston ring processing.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A fixed fixture for piston ring processing includes a device base, a placement frame mounted on the device base, a clamping rod movably connected to the outer side of the placement frame, a limit block mounted on the clamping rod, a turntable connected to the limit block, a support rod mounted on the turntable, the support rod connected to the device base, a third gear connected to one side of the turntable, and a first motor mounted on the outer side of the device base.

[0006] Preferably, a plurality of sliding grooves are arranged in a ring on the top surface of the device base, and sliding rods are installed between the inner walls of each sliding groove, with clamping rods movably connected to the outer sides of each sliding rod.

[0007] Preferably, the placement frame includes a middle block and an outer frame plate. The middle block is fixedly installed at the middle position on the top surface of the device base. Multiple outer frame plates are provided, all of which are installed in a ring on the outside of the middle block, and each outer frame plate is located between two sliding grooves, wherein a cutting space is left between the two sliding grooves.

[0008] Preferably, a lead screw is fixedly installed on the intermediate block, a lifting block is threadedly connected to the outer surface of the lead screw, a clamping frame is connected to the lifting block, the two ends of the clamping frame are rotatably connected to the lifting block, and positioning screws are connected to the two ends of the clamping frame.

[0009] Preferably, an inner groove is formed on the top surface of the inner side of the device base, and multiple support rods are arranged in a ring on the turntable. The top ends of the support rods are rotatably connected to the inner groove. Multiple adjustment grooves are formed on the turntable, and limit blocks are installed at the bottom ends of the clamping rods. The limit blocks are movably connected to the adjustment grooves.

[0010] Preferably, a fixing block is fixedly installed inside the device base, and a rotating rod is rotatably connected inside the fixing block. A third gear is installed at the top end of the rotating rod, and a first gear is provided at the bottom end of the rotating rod. A housing is provided on the outside of the device base, and the first motor is installed on the housing. A second gear is connected to the output end of the first motor, and the second gear meshes with the first gear.

[0011] The beneficial effects of this utility model are: This solution uses the rotation of the first motor to control the movement of the turntable, thereby driving multiple clamping rods to move back and forth within a range, achieving multi-point clamping of materials. The flipping of the clamping frame allows materials to be easily and smoothly placed onto the placement rack.

[0012] This solution reduces the possibility of objects becoming loose due to fewer clamping points after the equipment is clamped, reduces the possibility of disassembling parts during material placement, improves the stability of the clamping effect, achieves multi-point clamping, and enhances the support effect of the equipment. It can also prevent other parts from being cut during the cutting process and reduce the possibility of the equipment falling off during disassembly. Attached Figure Description

Sliding rods 4 are installed between the inner walls of the sliding grooves 3, and clamping rods 5 are movably connected to the outer side of each sliding rod 4 to achieve multi-point clamping of the piston ring and prevent loosening.

[0017] Specifically, the placement frame 2 includes a middle block and an outer frame plate. The middle block is fixedly installed in the middle position on the top surface of the device base 1. Multiple outer frame plates are provided, all of which are installed in a ring on the outside of the middle block to support the piston rings. The outer frame plates are all located between two sliding grooves 3, where a cutting space is left between the two sliding grooves 3. The piston rings in this part are left unattended to avoid being cut during the cutting process.

[0018] Furthermore, a lead screw 6 is fixedly installed on the intermediate block, and a lifting block is threadedly connected to the outer surface of the lead screw 6. A clamping frame 7 is connected to the lifting block, and the two ends of the clamping frame 7 are rotatably connected to the lifting block. Positioning screws are connected to the two ends of the clamping frame 7 to adjust and switch the clamping frame 7 between horizontal and vertical states, so as to avoid inconvenience when inserting the piston ring.

[0019] Furthermore, an inner groove 15 is provided on the top surface of the inner side of the device base 1, and multiple support rods 18 are arranged in a ring on the turntable 16. The top end of the support rod 18 is rotatably connected in the inner groove 15 to support the turntable 16. Multiple adjustment grooves 17 are provided on the turntable 16, and limit blocks 14 are installed at the bottom of each clamping rod 5.

The second gear 12 and the first gear 11 mesh with each other to drive the rotation of the turntable 16.

[0021] Working principle: When clamping the piston ring, the clamping frame 7 at the top is flipped upwards to a vertical position and fixed. Then, the piston ring is placed on the placement frame 2. Then, the first motor 9 is controlled to rotate, the second gear 12 drives the first gear 11 to rotate, and then the third gear 13 drives the turntable 16 to rotate. The clamping rod 5 will clamp and move closer to the middle position. After clamping is completed, the lifting block is adjusted downwards until it is pressed tightly on the piston ring. At this time, it can be processed. To disassemble, the above operation is reversed.
