Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of machining, and particularly to a multi-directional synchronous chamfering device for a valve bridge. Background Art
[0002] The valve bridge is generally a key component in the intake and exhaust mechanism assembly of a single camshaft engine. The function of the valve bridge is to evenly distribute the motion and force transmitted by the cam to the two valves of the same name in the same cylinder, ensuring that the two valves can be opened and closed simultaneously. Generally, the valve bridge is used in a single camshaft engine.
[0003] Most of the chamfering processes of the valve bridge mainly rely on manual operation. It is difficult to ensure the consistency of the chamfering values, and there will be cases of poor quality. Some valve bridge chamfering machines only perform chamfering operations on a single valve bridge, and for the double-axis holes of the valve bridge, chamfering needs to be carried out sequentially, resulting in low processing efficiency and unable to meet the actual use requirements.
[0004] Chinese Patent CN217167820U discloses a valve bridge chamfering machine, which relates to the technical field of machining, including a base and two symmetrically arranged fixed clamping seats on the surface of the base. A limit guide frame is vertically and fixedly connected to the surface of the base. A lifting screw is rotatably connected between the bottom and the top of the limit guide frame. A lifting table frame that cooperates with the lifting screw is slidably fitted on the side of the limit guide frame and on the top of the two fixed clamping seats. Two chamfering shaft frames corresponding to the fixed clamping seats are respectively rotatably connected to both ends of the lifting table frame. Through the coordinated use of the base, L-shaped clamping plate, push plate, lifting screw, lifting table frame, double-groove transmission wheel and chamfering shaft frame, this patent can realize the chamfering operation of the equipment on two valve bridges respectively. At the same time, the two chamfering shaft frames at both ends of the strip plate can chamfer the double-axis holes on the valve bridge in the fixed clamping seat simultaneously, further improving the efficiency and solving the problem that the chamfering operation in the prior art needs to be carried out one by one. However, in the actual production process, in order to match different models of engines, the models of the valve bridges in the exhaust mechanism of each engine are different, so that the equipment needs to be adjusted according to the shaft hole distances of different valve bridges during processing, reducing the production efficiency and increasing the burden on the staff.

Through the change of the distance between the two first chamfering components, the shaft holes of valve bridge workpieces of different sizes can be effectively adjusted, improving the adaptability of the equipment and effectively improving the production efficiency of valve bridge workpieces.

[0053] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0054] like Figures 1 to 5As shown: a multi-directional synchronous chamfering device for a valve bridge, comprising a support plate 1 and two first chamfering assemblies 2 arranged on the support plate 1, and a first adjusting mechanism 3, a first slide rail 11 and two second slide rails 12 are also arranged on the support plate 1; the first adjusting mechanism 3 is slidably located on the first slide rail 11; the two second slide rails 12 are respectively located on both sides of the first slide rail 11 in a mirror-symmetrical state with the sliding direction of the first adjusting mechanism 3 as the symmetry line, and the two second slide rails 12 are both arranged in an inclined state; the two first chamfering assemblies 2 are respectively slidably located on the two second slide rails 12, and the two first chamfering assemblies 2 are both transmission-connected with the first adjusting mechanism 3, and the first adjusting mechanism 3 is used to adjust the spacing between the two first chamfering assemblies 2, when the first adjusting mechanism 3 slides to one end of the first slide rail 11, the two first chamfering assemblies 2 are close to each other, and when the first adjusting mechanism 3 slides to the other end of the first slide rail 11, the two first chamfering assemblies 2 are away from each other.
[0055] Since the two second slide rails 12 are arranged in a mirror-symmetrical manner with the sliding direction of the first adjusting mechanism 3 as the symmetry line, and the two second slide rails 12 are both in an inclined state, the first adjusting mechanism 3 can simultaneously drive the two first chamfering components 2 that are both transmission-connected thereto when sliding back and forth along the first slide rail 11, so that the two first chamfering components 2 slide synchronously along the second slide rail 12, and the spacing between the two first chamfering components 2 changes with the sliding along the second slide rail 12. The change in the spacing between the two first chamfering components 2 can match the axial holes of valve bridge workpieces of different sizes for effective adjustment, and the adjustment is synchronous drive, which reduces the burden of equipment debugging on the staff. After the adjustment is completed, the support plate 1 is driven by the driving device to move toward the workpiece, so that the two axial holes on the valve bridge workpiece are synchronously processed by the two first chamfering components 2, thereby improving the adaptability of the equipment while effectively improving the production efficiency of the valve bridge workpiece.
[0056] like Figures 3 to 7 As shown: the first adjustment mechanism 3 includes a slider 31, which can be slidably located on the first slide rail 11, and a mounting seat 312 is provided on the top of the slider 31. A sleeve 313 placed in a horizontal state is provided on the mounting seat 312, and both ends of the sleeve 313 extend to the two first chamfering components 2 respectively. The two first chamfering components 2 are both provided with connecting rods 21 that match the sleeve 313, and the connecting rods 21 of the two first chamfering components 2 can be slidably located in both ends of the sleeve 313.
[0057] When the slider 31 reciprocates along the first slide rail 11, the slider 31 can drive the movement of the mounting base 312 located on its top, and drive the movement of the sleeve 313 through the mounting base 312. Since the connecting rods 21 of the two first chamfering components 2 can slide within the two ends of the sleeve 313, the movement of the sleeve 313 will drive the two connecting rods 21 to move together with the slider 31, thereby ensuring the synchronization degree of the two first chamfering components 2 and improving the adjustment accuracy of the two first chamfering components 2. By the sliding of the connecting rod 21 within the sleeve 313, the two first chamfering components 2 can still maintain transmission when approaching each other, and will not be interfered due to the too close position of the first chamfering component 2 and the slider 31, thus affecting the adjustment of the two first chamfering components 2. The structure is simple and practical, convenient for operation and maintenance, and can reduce the production cost.
[0058] As Figures 1 to 7 , Figure 10 and Figure 11 shown in the figure: A receiving table 13 is arranged below the support plate 1. A fixing base 131 is arranged on the receiving table 13. The fixing base 131 can slide on the receiving table 13, and the sliding direction of the fixing base 131 is the same as the sliding direction of the slider 31. The first adjusting mechanism 3 further includes a guiding frame 311. The guiding frame 311 is fixedly connected to the lower part of the slider 31, and the fixing base 131 is in transmission connection with the guiding frame 311.
[0059] In order to facilitate the machining of the shaft holes of the valve bridge workpiece, a fixed seat 131 is required. However, the fixed seat 131 is generally fixedly connected to the workbench. Based on the above embodiments, since the slider 31 will cause the distance between the two first chamfering components 2 to change, but the two first chamfering components 2 will move along the second slide rail 12 to change their machining positions. If the two first chamfering components 2 are used to machine the workpiece, the position of the fixed fixed seat 131 needs to be adjusted continuously, which will increase a large amount of workload and affect the machining efficiency. In order to facilitate the alignment of the fixed seat 131 with the two first chamfering components 2, through the setting of the guide frame 311 and the slidable fixed seat 131, the fixed seat 131 can move along with the slider 31 through the guide frame 311, so that no matter how the distance between the two first chamfering components 2 changes, the fixed seat 131 is always located below the two first chamfering components 2. Thus, a large amount of time for adjusting the position of the fixed seat 131 can be reduced, and the production efficiency can be improved. Through the setting of the receiving table 13, the structural strength between the fixed seat 131 and the guide frame 311 can be increased, making the sliding of the fixed seat 131 more stable, improving the accuracy of the fixed seat 131 moving along with the guide frame 311, and improving the stability of the equipment. The guide frame 311 is arranged in a rectangular structure, and guide grooves 3111 extending downward are arranged at the four end corners of the guide frame 311. The fixed seat 131 is also arranged in a rectangular structure, and guide bars 132 matching the four guide grooves 3111 are arranged on the fixed seat 131. The guide bars 132 can all slide in the guide grooves 3111, so that when the support plate 1 moves towards the fixed seat 131, it can be more stable, further improving the stability of the equipment and the machining accuracy of the equipment.
[0060] As Figures 6 to 11 shown: Clamping components 133 for positioning the workpiece are arranged on both sides of the fixed seat 131.
[0061] Through the arrangement of the clamping assembly 133, the fixed seat 131 can accurately position the workpiece, making the workpiece more stable when located on the fixed seat 131. The clamping assembly 133 includes a clamping plate 1331, a limiting block 1332, an elastic member 1334, and two support rods 1335. Fixing plates extending towards the guide frame 311 are arranged at both ends of the fixed seat 131. The guide strips 132 are fixedly connected to both sides of the fixing plates. The two support rods 1335 are horizontally arranged and can slide on the fixing plates. The clamping plate 1331 is located at one end of the two support rods 1335 close to the fixed seat 131. The limiting block 1332 is fixedly connected to the other ends of the two support rods 1335. The elastic member 1334 is sleeved on the two support rods 1335, and both ends of the elastic member 1334 are fixedly connected to the fixing plate and the limiting block 1332 respectively. The clamping plate 1331 is arranged in an arc structure. Through the arc structure of the clamping plate 1331, the clamping plate 1331 can not only play a role in centering and clamping the valve bridge workpiece but also better fit the end of the valve bridge workpiece, improving the stability of clamping the valve bridge workpiece. The two ends of the valve bridge workpiece are clamped by the elasticity of the elastic member 1334. When the workpiece needs to be disassembled, by pulling the limiting block 1332 on the clamping assembly 133, the limiting block 1332 slides towards the end away from the fixed seat 131. At this time, the elastic member 1334 will be compressed, causing the valve bridge workpiece to lose the clamping force, and thus the valve bridge workpiece can be removed from the fixed seat 131.
[0062] As Figures 4 to 11 shown: Both clamping assemblies 133 are in transmission connection with the guide frame 311. When the guide frame 311 approaches the fixed seat 131, the two clamping assemblies 133 clamp the workpiece. When the guide frame 311 moves away from the fixed seat 131, the two clamping assemblies 133 release the clamping of the workpiece.
[0063] Based on the above embodiments, since the clamping method of the clamping component 133 on the fixed seat 131 requires manual adjustment to release the clamping of the valve bridge workpiece, it is not convenient to use. To improve the automation degree of the equipment, sliding rods 1333 are arranged on both sides of the limiting block 1332 of the clamping component 133, and a guiding slide rail 314 matching the sliding rod 1333 is arranged on the guiding frame 311. The guiding slide rail 314 is inclined, and an opening 3141 is arranged at one end of the guiding slide rail 314 close to the clamping component 133. When the support plate 1 slides through the guiding groove 3111 of the guiding frame 311 and the guiding strip 132 of the fixed seat 131, when the support plate 1 approaches the fixed seat 131, the guiding slide rail 314 will contact the sliding rod 1333, and the sliding rod 1333 will slide into the guiding slide rail 314 from the opening 3141 of the guiding slide rail 314. Since the guiding slide rail 314 is inclined, the sliding rods 1333 on the two clamping components 133 clamp towards the center of the fixed seat 131 at the same time, thereby completing the clamping of the valve bridge workpiece. When the support plate 1 is reset, the sliding rods 1333 of the two clamping components 133 will slide along the guiding slide rail 314, so that the two clamping components 133 move away from each other, and the clamping component 133 can return to the initial position under the reset of the elastic member 1334, which is convenient for continuous placement of the workpiece. To facilitate the accurate transmission between the sliding rod 1333 and the guiding slide rail 314 each time, a flaring setting that expands to both sides is arranged at the opening 3141 of the guiding slide rail 314. To facilitate the placement of the valve bridge workpiece on the fixed seat 131 in the initial state, a groove 1311 can be arranged on the inner wall of the bottom of the fixed seat 131 for preliminary rough positioning. With the clamping of the clamping component 133, the valve bridge workpiece is subjected to secondary precise centering and alignment, so that the first chamfering component 2 can better process the valve bridge workpiece, improve the operation accuracy and operation efficiency, and improve the automation degree of the equipment.
[0064] As Figure 3 and Figure 4 shown: The first adjustment mechanism 3 further includes a driving component 32 for adjusting the reciprocating movement of the slider 31 along the first slide rail 11.
[0065] The driving component 32 includes a first rotary driving motor 321, a lead screw 322 and two mounting plates 323. The two mounting plates 323 are respectively fixedly connected to both ends of the first slide rail 11. The lead screw 322 is rotatably located between the two mounting plates 323. The first rotary driving motor 321 is fixedly connected to one of the mounting plates 323. The lead screw 322 is in transmission connection with the output shaft of the first rotary driving motor 321. The lead screw 322 passes through the slider 31 and is in threaded cooperation with it. By driving the lead screw 322 connected to it through the output shaft of the first rotary driving motor 321, and driving the slider 31 in threaded cooperation with it through the rotation of the lead screw 322, the slider 31 can slide along the first slide rail 11. At the same time, the distance between the two first chamfering components 2 can be adjusted through the sliding of the slider 31. And due to the self-locking characteristic of the threaded cooperation between the lead screw 322 and the slider 31, the adjusted slider 31 is not easy to change its position, ensuring the accuracy of the adjusted positions of the two first chamfering components 2. At the same time, the way of transmission adjustment by the lead screw 322 makes the control of the slider 31 more precise, improving the adjustment accuracy, which helps the first chamfering component 2 to better process the shaft hole of the valve bridge workpiece, improving the operation efficiency and accuracy, increasing the degree of automation, and reducing the burden on the staff.
[0066] As Figures 3 to 5 shown: Transmission wheels 22 are provided on both of the two first chamfering components 2, and a tension wheel 241 is further provided between the two first chamfering components 2. A second rotary driving motor 242 is provided below the tension wheel 241. A timing belt 221 is sleeved between the two transmission wheels 22 and the tension wheel 241.
[0067] If two first chamfering components 2 each use an independent drive source, it will increase the production cost and it is impossible to achieve synchronous start and stop, and the debugging is rather troublesome. In order to reduce the production cost, the synchronous belt 221 can be sleeved on the driving wheels 22 of the two first chamfering components 2. Driving any one of the first chamfering components 2 by a driving motor can solve the technical problem of synchronous rotation of the two first chamfering components 2. However, since the distance between the two first chamfers will change, the synchronous belt 221 cannot match the distance between them. Therefore, through the setting of the tensioning wheel 241, the tensioning wheel 241 can tighten the synchronous belt 221 between the two driving wheels 22, and the problem that the synchronous belt 221 cannot transmit due to the change in the distance between the two first chamfering components 2 is solved. Thus, a sliding seat 24 is further provided below the tensioning wheel 241, the second rotary driving motor 242 is fixedly connected to the sliding seat 24, a tensioning slide rail 23 parallel to the first slide rail 11 is provided beside the first slide rail 11, the sliding seat 24 can slide on the tensioning slide rail 23, and the sliding seat 24 is elastically connected to the mounting plate 323 of the driving component 32 on the first slide rail 11. Through the elastic connection, the tensioning wheel 241 can always keep the synchronous belt 221 tightened, and the second rotary driving motor 242 is fixedly connected to the bottom of the sliding seat 24, so that the structures of the two first chamfering components 2 are completely the same, avoiding possible errors when the slider 31 drives the two to slide after the drive source is installed on any one of the two first chamfering components 2. By driving the rotation of the tensioning wheel 241 by the second rotary driving motor 242, the two driving wheels 22 are simultaneously driven by the synchronous belt 221 on the tensioning wheel 241. Thus, the production cost can be reduced, and the two first chamfering components 2 can be simultaneously driven to operate synchronously by a single drive source.
[0068] As Figures 1 to 5 shown: A second adjusting mechanism 16, a third slide rail 14, two second chamfering components 17 and two fourth slide rails 15 which are mirror-symmetrically arranged with respect to the first adjusting mechanism 3, the first slide rail 11, the two first chamfering components 2 and the two second slide rails 12 are further provided on the support plate 1. The structures of the second adjusting mechanism 16 and the two second chamfering components 17 are completely the same as those of the first adjusting mechanism 3 and the two first chamfering components 2.
[0069] Through the setting of the second adjusting mechanism 16, the third slide rail 14, the two second chamfering components 17 and the two fourth slide rails 15 which are mirror-symmetrically arranged with respect to the first adjusting mechanism 3, the first slide rail 11, the two first chamfering components 2 and the two second slide rails 12, the two valve bridge workpieces can be processed simultaneously on both sides of the support plate 1, further improving the production efficiency of processing the valve bridge workpieces. And because the first adjusting mechanism 3 and the second adjusting mechanism 16 have their own independent drive sources, the two can process the valve bridge workpieces with shaft holes of different distances simultaneously, improving the adaptability of the equipment.
[0070] AsFigures 1 to 5 As shown: The support plate 1 is a rectangular plate-like structure. Vertical guide posts 18 are provided at the four end corners of the support plate 1. A frame 4 is arranged above the support plate 1. All four guide posts 18 are slidably engaged with the frame 4. A linear actuator 41 is arranged at the center of the frame 4. The mounting plate 323 is drivingly connected to the output end of the linear actuator 41.
[0071] Through the arrangements of the frame 4, the linear actuator 41, the support plate 1 and the four guide posts 18, the support plate 1 can slide along the axial direction of the guide posts 18 and be located below the frame 4. Through the support plate 1, the two first chamfering assemblies 2 and the two second chamfering assemblies 17 can simultaneously process the valve bridge workpieces on both sides of the support plate 1, improving production efficiency and operation accuracy.
[0072] As Figure 1 , Figure 2 , Figure 9 and Figure 10 As shown: A blanking port 134 is arranged at the center of the receiving table 13. Telescopic guide plates 1342 are arranged on both sides of the blanking port 134 close to the first adjusting mechanism 3 and the second adjusting mechanism 16 respectively. The guide plates 1342 are rotatably connected to the blanking port 134. The two guide plates 1342 are respectively connected to the fixed seats 131 of the first adjusting mechanism 3 and the second adjusting mechanism 16. Retaining plates 1341 for preventing workpieces from sliding out are arranged on both sides of the receiving table 13.
[0073] Through the arrangement of the blanking port 134, the processed valve bridge workpieces can directly slide into the blanking port 134 through pushing. However, since the fixed seat 131 is sliding, the valve bridge workpieces cannot accurately fall into the blanking port 134, and the valve bridge workpieces may slide out of the receiving table 13, causing the staff to collect the valve bridge workpieces in this part, increasing the burden on the staff. Through the arrangement of the guide plates 1342, because they can be telescopic and are respectively connected to the blanking port 134 and the fixed seat 131, when the fixed seat 131 slides, it can drive the guide plates 1342 to move with it, making the guide plates 1342 inclined. No matter which position the fixed seat 131 moves to, the valve bridge workpieces can be accurately guided to the blanking port 134 for convenient collection. Through the arrangements of the two retaining plates 1341 on both sides, the retaining plates 1341 can match the sliding of the fixed seat 131, so that the valve bridge workpieces cannot slide off the guide plates 1342 and can only fall into the blanking port 134.
[0074] The above embodiments merely represent one or several implementation manners of the present invention. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent for the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the patent for the present invention shall be subject to the appended claims.
