Description

Technical Field

[0001] This utility model relates to the field of cold forging radiator processing technology, and in particular to a CNC precision machining fixture for cold forging radiators. Background Technology

[0002] CNC precision machining fixtures are auxiliary devices used in the field of machining. They are used to firmly fix the workpiece in a specific position during the precision machining process of CNC machining equipment. Through positioning and clamping, CNC precision machining fixtures ensure that the workpiece will not be displaced due to external forces during the machining process, thereby ensuring machining accuracy.

[0003] The CNC precision machining fixture for cold-forged radiators is a fixing device specifically designed for use during the CNC precision machining of radiators produced by the cold-forging process. Cold-forged radiators require high-precision fixing during CNC precision machining to ensure the machining accuracy of the heat dissipation fins and mounting holes. This fixture needs to be designed according to the shape and structural characteristics of the cold-forged radiator, capable of positioning the radiator and clamping it to maintain stability during machining, ensuring that the CNC machining equipment can process the radiator according to the preset program.

[0004] Traditional fixtures use clamping points to fix cold-forged radiators. Areas far from the clamping points are not securely fixed, causing slight displacement of the radiator during processing and affecting machining accuracy. To solve this problem, existing technology uses elastic rubber pads at the clamping points to distribute the clamping force evenly on the radiator surface. This ensures both a secure fixation and reinforcement accuracy while preventing excessive local pressure from damaging the radiator. However, in practical use, existing fixtures are designed for specific sizes of cold-forged radiators. When processing radiators of different sizes, the entire fixture needs to be replaced, increasing production costs and preparation time. Utility Model Content

[0010] As a further description of the above technical solution: The mounting assembly includes multiple fixing seats, which are respectively located at the four corners of the corresponding connecting seats. One side of each fixing seat is fixedly connected to the other side of the corresponding connecting seat. Each fixing seat has a screw on its top. The bottom end of each screw passes through the top of the corresponding fixing seat and is threaded to the inner wall of the processing base. Each screw has a washer slidably connected to its outer wall. The bottom of each washer is in contact with the top of the corresponding fixing seat.

[0011] As a further description of the above technical solution: The left and right ends of the two L-shaped moving blocks on opposite sides are fixedly connected to reinforced triangular blocks, and the bottoms of the multiple reinforced triangular blocks are fixedly connected to the tops of the corresponding sliding seats.

The turntable is rotated, and the bidirectional threaded rod drives the two L-shaped moving blocks to move towards each other along the guide rail. The clamping pad is pressed against the side to achieve lateral fixation. Then, the adjustment handle is turned, and the threaded column drives the lower pressure block to descend. The lower pressure pad completes the longitudinal pressing. The clamping pad and lower pressure pad are made of elastic material to prevent crushing. The lateral spacing and longitudinal pressure are adjustable to adapt to different specifications.

[0015] 2. In this utility model, when the radiator is placed on the top of the positioning platform, the hydraulic rod extends and pushes the positioning block closer to the radiator. The positioning pad first contacts the side of the radiator to buffer the contact force and prevent scratches. The positioning sensor monitors the distance in real time. When the distance reaches the preset value, the sensor sends a signal to stop the hydraulic rod, ensuring that the radiator is centered and stable. To adapt to radiators of different sizes, only the extension and retraction of the hydraulic rod needs to be adjusted. No parts need to be replaced. Flexible adjustment is achieved through hydraulic drive, which solves the problems of poor adaptability and easy damage to workpieces in traditional mechanisms. Attached Figure Description

The positioning mechanisms 3 are used to restrict the movement of the radiator in the left and right directions. The fixing mechanism 2 includes two L-shaped moving blocks 201, which are respectively disposed on the front and rear sides of the top of the processing base 1. The two L-shaped moving blocks 201 can move along the guide sliding assembly 207 to adjust the spacing. A clamping block 202 is fixedly connected to each adjacent side of the two L-shaped moving blocks 201. The clamping block 202 is used to directly contact and clamp the heat sink. A clamping pad 203 is fixedly connected to each adjacent side of the two clamping blocks 202. The clamping pad 203 is made of elastic material to avoid damaging the surface of the heat sink. The inner top left and right ends of 201 are threaded with threaded posts 204. The threaded posts 204 can move up and down by rotation. The bottom ends of multiple threaded posts 204 are fixedly connected with pressure blocks 205. The pressure blocks 205 are used to press the radiator from the top. The bottom of multiple pressure blocks 205 is fixedly connected with pressure pads 206. The pressure pads 206 can reduce pressure damage to the top of the radiator. The bottom of the two L-shaped moving blocks 201 is provided with guide slide components 207. The guide slide components 207 provide guidance for the movement of the L-shaped moving blocks 201. The guide rail assembly 207 includes two guide rails 2071, the bottoms of which are fixedly connected to the top left and right sides of the processing base 1, respectively. The guide rails 2071 provide a moving track for the sliding seat 2073. Each of the two guide rails 2071 has a guide groove 2072 on its left and right sides, which is used to cooperate with the bidirectional threaded rod 2081 to achieve transmission. The bottoms of the two L-shaped moving blocks 201 are fixedly connected to sliding seats 2073, which connect the L-shaped moving blocks 201 and the guide rails 2071. The bottom left and right sides of 073 are provided with guide grooves 2075. The guide grooves 2075 cooperate with the guide rails 2071 to ensure smooth sliding. The inner walls of the multiple guide grooves 2075 are slidably connected to the outer walls of the corresponding guide rails 2071. The front and rear sides of the inner walls of the multiple guide grooves 2075 are slidably connected to the corresponding guide blocks 2074. The guide blocks 2074 can reduce the friction between the sliding seat 2073 and the guide rails 2071. One side of the inner wall of the multiple guide grooves 2075 is fixedly connected to the other side of the corresponding guide blocks 2074. The drive assembly 208 includes a bidirectional threaded rod 2081. The outer and rear sides of the bidirectional threaded rod 2081 are threadedly connected to the inner walls of the corresponding guide grooves 2072.

The threaded post 204 at the top of the L-shaped moving block 201, in conjunction with the adjusting handle 2083, can precisely adjust the height of the lower pressure block 205 to adapt to different workpiece thickness requirements. The lower pressure pad 206 further buffers the pressure, preventing workpiece damage under pressure and ensuring stable fixation without damaging the workpiece. The guide rail 2071 and the guide slide groove 2075 of the sliding seat 2073 slide in conjunction, supplemented by the guide slider 2074, so that the L-shaped moving block 201 moves smoothly and steadily, reducing adjustment jamming and improving operation convenience. The bidirectional threaded rod 2081 of the drive assembly 208, in conjunction with the turntable 2082, facilitates manual drive adjustment, making operation labor-saving and efficient.

[0020] Reference Figure 1 , Figure 2 and Figure 3 The positioning mechanism 3 includes two connecting seats 301, which are respectively set on the top left and right sides of the processing base 1 to support other components of the positioning mechanism 3. The top of each connecting seat 301 is fixedly connected to a hydraulic rod 302, which can move the positioning block 303 by extension and retraction. The adjacent ends of the two hydraulic rods 302 are fixedly connected to the positioning block 303, which can directly contact and position the workpiece. The adjacent sides of the two positioning blocks 303 are fixedly connected to a positioning pad 304, which can prevent the positioning block 303 from hard contacting the workpiece and causing scratches. The top of each positioning block 303 is fixedly connected to a positioning sensor 305, which can monitor the relative position of the positioning block 303 and the workpiece in real time to ensure accurate positioning. The outer walls of the two connecting seats 301 are provided with mounting components 306, which are used to securely install the connecting seat 301 on the processing base 1. Mounting assembly 306 includes multiple fixing seats 3061, which are respectively located at the four corners of the corresponding connecting seat 301 to enhance the stability of the connecting seat 301 installation. One side of each fixing seat 3061 is fixedly connected to the other side of the corresponding connecting seat 301, so that the fixing seat 3061 and the connecting seat 301 form an integral structure. Each fixing seat 3061 has a screw 3062 on its top for locking the fixing seat 3061 to the processing base 1. The bottom ends of each screw 3062 pass through the top of the corresponding fixing seat 3061 and are threaded to the inner wall of the processing base 1 to achieve a rigid connection between the connecting seat 301 and the processing base 1. Each screw 3062 has a washer 3063 slidably connected to its outer wall to increase the contact area between the screw 3062 and the fixing seat 3061 and prevent the fixing seat 3061 from being deformed by pressure. The bottom of each washer 3063 is in contact with the top of the corresponding fixing seat 3061 to ensure that the washer 3063 fully plays its buffering role. Specifically, the two connecting seats 301 are stably connected to the processing base 1. The hydraulic rod 302 on the top can drive the positioning block 303 to move, adapting to the positioning requirements of workpieces of different specifications. The positioning pads 304 on the adjacent sides of the positioning block 303 can prevent scratches on the workpiece surface and play a protective role. The positioning sensor 305 can monitor the positioning status in real time to ensure accurate positioning. In the installation component 306, the fixing seat 3061 cooperates with the screw 3062 and the washer 3063 to enhance the connection stability between the connecting seat 301 and the processing base 1. The operation is convenient and can realize the positioning of the workpiece, improving the stability and reliability of the processing process.

[0021] Reference Figure 1 , Figure 2 and Figure 4 Two L-shaped movable blocks 201 are fixedly connected to the left and right ends of their opposite sides with stiffened triangular blocks 5. The stiffened triangular blocks 5 enhance the structural strength of the connection between the L-shaped movable blocks 201 and the sliding seat 2073, preventing deformation under stress. The bottoms of the multiple stiffened triangular blocks 5 are fixedly connected to the tops of the corresponding sliding seats 2073, which provide stable support for the L-shaped movable blocks 201. Limiting blocks 6 are fixedly connected to the front and rear ends of the two guide rails 2071, which limit the movement range of the sliding seats 2073. To prevent it from slipping off the guide rail 2071, one side of each of the multiple limit blocks 6 is respectively attached to the other side of the corresponding sliding seat 2073 to ensure that the sliding seat 2073 moves smoothly within the limited range. The front and rear sides of the outer wall of the bidirectional threaded rod 2081 are rotatably connected to the stabilizing seat 7. The stabilizing seat 7 can enhance the stability of the bidirectional threaded rod 2081 when it rotates and prevent it from swaying radially. The bottom of the two stabilizing seats 7 is respectively fixedly connected to the front and rear sides of the top of the processing base 1. The processing base 1 provides a stable installation foundation for the stabilizing seat 7. Specifically, the reinforced triangular block 5 enhances the connection strength between the L-shaped moving block 201 and the sliding seat 2073, preventing deformation under stress; the limiting block 6 restricts the movement range of the sliding seat 2073, preventing slippage and improving operational stability; the stabilizing seat 7 ensures smooth rotation of the bidirectional threaded rod 2081, reducing shaking and improving the structural strength and operational reliability of the device.

[0022] Working principle: When using the precision machining fixture, place the cold-forged radiator to be machined on the top of the positioning table 4, align the positioning hole at the bottom of the radiator with the positioning pin 8 and insert it to complete the positioning, ensuring that the machining datum of the radiator is aligned with the equipment coordinate system. Rotate the turntable 2082 to drive the connected bidirectional threaded rod 2081 to rotate. Since the front and rear threads of the bidirectional threaded rod 2081 are opposite in direction and are respectively threaded to the inner wall of the guide groove 2072 of the front and rear L-shaped moving blocks 201, it will drive the two L-shaped moving blocks 201 to move towards each other along the guide rail 2071. The sliding seat 2073 slides on the guide rail 2071 through the second guide groove 2075. The guide slider 2074 is embedded in the first guide groove 2072 for auxiliary guidance to avoid deviation during movement, until the clamping pads 203 on the clamping blocks 202 on both sides are tightly closed. The fixture fits snugly against the front and rear sides of the radiator to secure it. The spacing can be flexibly adjusted via the threaded drive of the bidirectional threaded rod 2081 to accommodate radiators of different sizes. Then, depending on the thickness of the radiator, the adjustment handle 2083 is rotated, causing the connected threaded column 204 to rotate within the threaded hole of the L-shaped moving block 201, which in turn causes the lower pressure block 205 to descend vertically. When the lower pressure pad 206 contacts the top of the radiator, the pressure is further fine-tuned to the appropriate level. The clamping pad 203 and the lower pressure pad 206 are made of elastic material to prevent damage to the workpiece surface, thus completing the longitudinal clamping and securing. By adjusting the lateral spacing with the bidirectional threaded rod 2081 and adjusting the longitudinal pressure with the adjustment handle 2083, different sizes of cold-forged radiators can be quickly adapted. This solves the problem of traditional fixtures requiring complete replacement, shortens changeover time, and reduces production costs. Furthermore, when the positioning mechanism 3 is in operation, it is first fixed by the mounting component 306. The fixing seat 3061 fits against the processing base 1, and the screw 3062 passes through the washer 3063 and is screwed into the base to firmly fix the connecting seat 301, preventing shaking during operation. When the radiator is placed on the top of the positioning table 4, the hydraulic rod 302 extends, pushing the positioning block 303 closer to the radiator. The positioning pad 304 first contacts the side of the radiator to buffer the contact force and prevent scratching the workpiece. At the same time, the positioning sensor 305 monitors the distance between the positioning block 303 and the radiator in real time. When the distance reaches the preset value, ensuring that the radiator is centered and stable, the sensor sends a signal, and the hydraulic rod 302 immediately stops extending. To adapt to radiators of different sizes, only the extension and retraction of the hydraulic rod 302 needs to be adjusted, and the distance between the positioning blocks 303 changes accordingly without replacing any parts. This process achieves flexible adjustment through hydraulic drive, solving the problems of poor adaptability and easy damage to the workpiece in the traditional positioning mechanism 3, further improving positioning accuracy and workpiece protection.
