Description

Technical Field

[0001] This invention relates to the field of engine manufacturing technology, specifically to an integrated connecting rod machining fixture. Background Technology

[0002] In the field of engine manufacturing, the connecting rod is a core moving component that bears alternating loads. The accuracy of the diameter of its large end hole and small end hole, as well as the machining quality of the center distance between the two holes, directly affect the reliability and lifespan of the engine.

[0003] In existing connecting rod machining fixtures, positioning is mostly achieved using manual locating pins or single-cylinder drive. Operators need to manually insert the locating pins into the locating holes at both ends of the connecting rod, which is not only inefficient but also greatly affected by human factors, making it difficult to guarantee the consistency of batch processing.

[0004] Meanwhile, the large-end hole and the small-end hole of the connecting rod usually have different dimensions and tolerance ranges. Traditional fixtures using locating pins of the same specification cannot simultaneously compensate for the tolerance differences of the hole diameters at both ends, which can easily lead to positioning misalignment or over-positioning, affecting machining accuracy. In addition, the clamping method of existing fixtures is mostly single vertical clamping, which has poor fit to irregular connecting rod structures, and the height is fixed, making it unable to adapt to the machining requirements of connecting rods of different specifications.

[0005] Therefore, there is an urgent need for an integrated machining fixture for connecting rods that can achieve high-precision combined positioning of the large and small ends, multi-point coordinated clamping, and adjustable height. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated connecting rod machining fixture to solve the problems of existing connecting rod machining fixtures having a single positioning method that cannot compensate for the difference in tolerance between the large and small end holes, and a single clamping method and fixed height that makes it difficult to adapt to irregular structures and connecting rods of different specifications.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated machining fixture for connecting rods, comprising a machine housing, an upper table, a mounting base, a docking device, a clamping assembly, a two-way cylinder seat, a fixing assembly, and an adjusting assembly; The upper platform is fixedly connected to one side of the upper surface of the equipment housing, and two sets of mounting seats are arranged on the upper surface of the equipment housing, with two mounting seats in each set; Two sets of clamping components are arranged and installed on the upper surface of the upper platform, and each set of clamping components consists of two components.

The docking device is also fixedly installed on the inner and outer ends of the mounting bases respectively. The upper surface of the upper platform is also fixedly mounted with a plurality of bidirectional cylinder seats.

[0008] Preferably, a cylinder is fixedly mounted on the outer surface of the upper end of each of the four mounting seats, and a U-shaped push column is fixedly mounted on the front end of each cylinder to the inner outer end of the mounting seat. Each of the four mounting bases has a sliding rod on its inner end surface, and an elastic support column is provided in the center of each of the two sliding rods. The lower ends of the slide bar and the elastic support column are both fixedly connected to the upper surface of the equipment housing.

[0009] Preferably, the two sets of docking devices each include cylinder two fixedly installed at both ends inside the equipment housing, and push plates installed at the outer ends of the two sets of slide rods; The upper end of each cylinder is fixedly connected to a connecting plate, and the upper ends of the connecting plate are fixedly connected to top columns. The upper ends of the top columns pass through the inside of the equipment housing and are fixedly connected to the center of the lower surface of the two push plates. The two ends of the push plate are slidably fitted to the outer ends of the elastic support column, and a positioning pin is fixedly connected to the center of the upper surface of the push plate.

[0010] Preferably, each of the four fixing components includes a cylinder four fixedly installed on the outer end of one side of the mounting base, a mounting plate is installed on the upper end of each cylinder four, and a clamping plate is provided on the upper end of the connecting rod two. A piston rod 2 is also connected to the center of the upper surface of the cylinder 4, and the upper end of the piston rod 2 is fixedly connected to the lower rear end surface of the pressure plate. The front end of the clamping plate is positioned directly above the positioning pin, and the second connecting rod is rotatably connected to the center of the lower surface of the clamping plate. The other end of the second connecting rod is rotatably connected to the upper surface of the mounting plate.

[0011] Preferably, each of the two sets of adjustment components includes a cylinder five fixedly installed at both ends inside the equipment housing. A connecting plate two is fixedly connected to the lower end of each cylinder five. A top column two is fixedly installed at both ends of the upper surface of the connecting plate two. The top column two extends through the inside of the equipment housing and the upper platform to the upper outer end of the upper platform, and a placement platform is fixedly installed thereon.

[0012] Preferably, each of the four clamping components includes a cylinder three arranged and installed at the rear end of the upper surface of the upper platform, a piston rod one connected to the center of the upper surface of each cylinder three, and a U-shaped fitting block rotatably connected to the upper end of the piston rod one; The front end of the U-shaped bonding block is positioned directly above the placement platform. A connecting rod is rotatably connected to the lower center surface of the U-shaped bonding block, and the lower end of the connecting rod is rotatably connected to one side of the upper surface of the cylinder.

[0013] Preferably, the clamping assembly further includes four inclined cylinders arranged and installed on one side of the outer end of the cylinder, and each inclined cylinder has a fixedly connected fitting rod inside.

[0014] Preferably, multiple bidirectional cylinder seats are provided and are fixedly installed on the center of the upper surface of the upper platform. The multiple bidirectional cylinder seats are arranged in parallel. Positioning rods are installed on both sides of the bidirectional cylinder seats, and the front ends of the positioning rods are respectively set to correspond to the placement platform.

[0015] Compared with the prior art, the beneficial effects of the present invention are: This fixture employs a combination of large-hole locating pins (expansion pin structure, gap 0.3-0.4mm) and small-hole locating pins (diamond pin structure, gap 0.05-0.08mm), which are inserted into the locating holes at the large and small ends of the connecting rod, respectively, effectively compensating for the manufacturing tolerances of the workpiece's locating holes. Simultaneously, the large-hole locating pin is pulled down at two stations by a pull-down cylinder via a linkage mechanism, while the small-hole locating pin is moved up and down on the left and right guide locating posts by another pull-down cylinder. After positioning, they are pulled down synchronously to achieve positioning. The elastic support column provides cushioning during the push plate's ascent, avoiding rigid impact and ensuring the smoothness and repeatability of the locating pin insertion.

[0016] The U-shaped fitting block of this fixture is a contour-following pressure plate structure, its shape corresponding to the plane of the large end of the connecting rod. Driven by a lever cylinder, it presses the large end of the connecting rod from above. An oblique cylinder drives a fitting push rod to provide oblique support from the side, forming three support points on the left and right sides and the top of the large end. Positioning push rods on both sides of the bidirectional cylinder seat provide auxiliary positioning from the left and right directions. The clamping plate of the fixing component presses the workpiece end above the positioning pin. This multi-directional, multi-point coordinated clamping and positioning effectively suppresses vibration during processing. Simultaneously, the cylinder five of the adjusting component drives the platform to rise and fall via the push column two, allowing for rapid adjustment of the workpiece height to accommodate the path requirements of different connecting rod specifications and different machining tools, significantly improving the fixture's versatility and processing stability.

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

[0020] Please see Figures 1-6 As shown, the present invention provides a technical solution: an integrated linkage machining fixture, wherein the equipment housing 1 has a rectangular box structure, and the interior of the equipment housing 1 is a hollow structure to accommodate driving components such as cylinder 41 and cylinder 81. The upper surface of the equipment housing 1 is flat. Shock-absorbing pads are located at the four corners of the bottom of the equipment housing 1.

[0021] The upper table 2 is located on one side of the upper surface of the equipment housing 1. The upper table 2 is located in a semi-side area of ​​the upper surface of the equipment housing 1 (based on the operator's facing direction). The upper surface of the upper table 2 is treated. Multiple through holes are present on the upper table 2 corresponding to the positions of the top post 83 and the fitting top rod 56. The upper table 2 is the third-layer machine tool connection main board in the fixture positioning main board. Its thickness corresponds to the height and pull-down space of the upper mechanism, supporting the entire upper positioning structure and being fixedly connected to the machine tool worktable.

[0022] Mounting seats 3 are located on the upper surface of the equipment housing 1, consisting of two groups of four seats in total. Each group has two mounting seats 3 located on the left front, left rear, right front, and right rear sides of the upper surface of the equipment housing 1, respectively. Each mounting seat 3 has an L-shaped structure, including a horizontal base and a vertical plate. The horizontal base is connected to the upper surface of the equipment housing 1 via a connector, and the vertical plate extends upwards perpendicular to the horizontal base. The mounting seats 3 form a layered structure of the first large-end positioning main board and the second small-end positioning main board in the fixture positioning main board, arranged vertically above and below each other.

[0023] like Figure 2 As shown, each mounting base 3 has a cylinder 31 on its upper outer surface (i.e., the outer side of the vertical plate). Cylinder 31 is a linear cylinder, with its piston rod extending horizontally to the inner outer end of the mounting base 3 (i.e., the inner side of the vertical plate). A U-shaped push post 32 is located at the front end of the piston rod. The U-shaped push post 32 has a U-shaped fork structure with its open end facing inwards. A buffer pad is present on the front surface of the U-shaped push post 32. The U-shaped push post 32 serves as an auxiliary limiting device for the large end of the connecting rod, with an auxiliary limiting structure at the large end blank outline.

[0024] Each mounting base 3 has a sliding rod 33 on both inner end surfaces (i.e., both ends of the inner side of the vertical plate). The sliding rod 33 serves as a guide rod and runs vertically. At the center of each sliding rod 33 is an elastic support column 34. The elastic support column 34 includes an inner column and an elastic element sleeved outside the inner column. The lower end of the elastic element is on the upper surface of the equipment housing 1, and the upper end is on the lower surface of the push plate 44. The lower ends of both the sliding rod 33 and the elastic support column 34 are on the upper surface of the equipment housing 1. The sliding rod 33 is connected to the equipment housing 1 via bearings, and the lower end of the inner column of the elastic support column 34 is connected to the upper surface of the equipment housing 1 via a connector.

[0025] There are two sets of docking devices 4, corresponding to the mounting bases 3 on the left and right sides respectively. For example... Figure 3 , Figure 4As shown, each docking device 4 includes cylinders 41 at both ends inside the equipment housing 1, and push plates 44 at the outer ends of the two sets of sliding rods 33. Cylinder 41 is a vertical linear cylinder, with its cylinder body on the inner bottom surface of the equipment housing 1. The upper piston rod end of cylinder 41 has a connecting plate 42, which is a horizontal plate. At both ends of the upper surface of the connecting plate 42, there are vertical top posts 43, which are guide rods. The upper ends of the top posts 43 pass through the top wall of the equipment housing 1 to the outside of the equipment housing 1, and are located at the center of the lower surface of the two push plates 44. Push plates 44 are long strip plates, horizontal in shape. Both ends of push plates 44 have guide holes, which are slidably engaged with the outer ends of the elastic support columns 34 (i.e., the ends of push plates 44 are on the outer periphery of the elastic support columns 34 and can slide along the axial direction of the elastic support columns 34). There is a positioning pin 45 in the center of the upper surface of the push plate 44. The positioning pin 45 is a pin body with a chamfer at the top.

[0026] The locating pins are divided into large-hole locating pins and small-hole locating pins: the large-hole locating pins are expansion pins with a clearance of 0.3-0.4mm; the small-hole locating pins are diamond pins with a clearance of 0.05-0.08mm between the diamond pin and the hole diameter. Both large and small-hole locating pins are pulled down after positioning. The pulling down of the large-hole locating pins is controlled simultaneously at two stations by a pull-down cylinder via a linkage mechanism; the small-hole locating pins are positioned on the small-end locating block via left and right guide locating posts, and the small-end locating block is moved up and down along the height direction of the left and right guide locating posts by another pull-down cylinder, with the cylinder stroke corresponding to the path of the roughing and finishing composite tool.

[0027] The working state of the docking device 4 is as follows: After cylinder 2 41 is started, the piston rod moves upward, driving the push plate 44 upward along the slide rod 33 and the elastic support column 34 via the connecting plate 1 42 and the top column 1 43. The positioning pin 45 rises into the positioning hole at the end of the connecting rod workpiece. The elastic support column 34 provides cushioning during the upward movement of the push plate 44. After positioning is completed, cylinder 2 41 reverses direction, the positioning pin 45 is pulled down, and the positioning pin 45 exits the workpiece positioning hole.

[0028] There are two sets of clamping components 5, two in each set, for a total of four, located at the rear end of the upper surface of the upper platform 2. The mounting base 3 is opposite to the clamping components 5; that is, the mounting base 3 is at the front end of the upper surface of the equipment housing 1, and the clamping components 5 are at the rear end of the upper surface of the upper platform 2, with the two facing each other. Figure 5As shown, each clamping assembly 5 includes a cylinder 3 51 at the rear end of the upper surface of the upper platform 2. Cylinder 3 51 is a vertical linear cylinder, and its cylinder body is connected to the upper surface of the upper platform 2 via a connector. Cylinder 3 51 has a lever cylinder structure. A piston rod 1 53 is located at the center of the upper surface of cylinder 3 51, and a U-shaped fitting block 52 is hinged to the upper end of piston rod 1 53. The U-shaped fitting block 52 has a U-shaped structure, with its front end (i.e., the open end) directly above the placement platform 84. A pressure pad is located on the lower surface of the front end of the U-shaped fitting block 52. The U-shaped fitting block 52 is a contour-following pressure plate structure, its shape corresponding to the planar structure of the large end of the connecting rod, without interfering with the tool path, and the clamping point is in the rod cap mating area. At the large end of the connecting rod, the U-shaped fitting block 52 and the lever cylinder clamp the large end planarly; at the small end of the connecting rod, the lever cylinder also clamps the large end, with the clamping points on the left and right sides of the center of the connecting rod. A connecting rod 54 is hinged to the lower center of the U-shaped bonding block 52. The lower end of the connecting rod 54 is hinged to one side of the upper surface of the cylinder 51 (that is, the lower end of the connecting rod 54 is on one side of the upper surface of the cylinder body of the cylinder 51 through a support).

[0029] like Figure 5 As shown, the clamping assembly 5 also includes four inclined cylinders 55 on one side of the outer end of cylinder 3 51. The inclined cylinders 55 are inclined cylinders, and their cylinder bodies are mounted on the upper surface of the upper platform 2 via supports, on the outer end side of cylinder 3 51. The piston rod of the inclined cylinder 55 has a contacting push rod 56 inside its front end. The front end of the contacting push rod 56 has a hemispherical structure, oriented obliquely towards the placement platform 84. The contacting push rod 56 serves as the actuator for the support cylinder. There are three support cylinders on the large end positioning main plate, located on the left and right sides and the top of the large end. The axis of the inclined cylinder 55 forms an angle of 30° to 60° with the horizontal plane; in this embodiment, this angle is 45°.

[0030] The working state of the clamping assembly 5 is as follows: the piston rod 53 of cylinder 3 51 moves upward, pushing the rear end of the U-shaped bonding block 52 upward, the connecting rod 54 stops, the U-shaped bonding block 52 rotates around its hinge point with the piston rod 53, and the front end of the U-shaped bonding block 52 faces downward, on the upper surface of the connecting rod workpiece on the placement platform 84. At the same time, the inclined cylinder 55 drives the bonding top rod 56 to move obliquely from the side of the workpiece.

[0031] There are multiple (specifically three) double-acting cylinder blocks 6, each located at the center of the upper surface of the upper platform 2, with two double-acting cylinder blocks 6 arranged parallel to each other in the front-to-back direction. For example... Figure 6 As shown, the double-acting cylinder block 6 has a double-headed cylinder structure, with its cylinder body located on the upper surface of the upper platform 2. Positioning push rods 61 are located on both sides of the double-acting cylinder block 6, with the front ends of the positioning push rods 61 corresponding to the placement platforms 84, and the left and right positioning push rods 61 facing the left and right placement platforms 84 respectively. The front ends of the positioning push rods 61 have buffer heads. The stroke of the positioning push rods 61 matches the stroke of the pull-down cylinder.

[0032] There are four fixing components 7, located on one side of the outer end of each of the four mounting bases 3. For example... Figure 3 As shown, each fixing component 7 includes a cylinder 4 71 located at the outer end of one side of the mounting base 3 (i.e., the outer surface of the vertical plate of the mounting base 3). Cylinder 4 71 is a vertical linear cylinder, and its cylinder body is mounted on the outer surface of the mounting base 3 via a disc. A mounting plate 72 is located at the upper end of cylinder 4 71. The mounting plate 72 is horizontal, with one end on the upper end of the cylinder body of cylinder 4 71 and the other end extending outwards. A support is located on the upper surface of the mounting plate 72. A piston rod 2 75 is located at the center of the upper surface of cylinder 4 71, with its upper end resting on the lower rear end of the clamping plate 74. The clamping plate 74 is an elongated plate, with its front end directly above the locating pin 45. A connecting rod 2 73 is located at the center of the lower surface of the clamping plate 74, with its other end resting on a support on the upper surface of the mounting plate 72. The connecting rod 73 is a connecting rod structure. When the piston rod 75 of the cylinder 71 moves up and down, the rear end of the pressing plate 74 rises or falls under the traction and limitation of the connecting rod 73, and the front end swings in the opposite direction.

[0033] The working state of the fixed component 7 is as follows: the piston rod 75 of the cylinder 4 71 moves upward, driving the rear end of the clamping plate 74 to rise. The clamping plate 74 swings around the rotation connection point with the connecting rod 73. The front end of the clamping plate 74 moves downward, on the upper surface of the workpiece end above the positioning pin 45.

[0034] There are two sets of adjustment components 8, located at opposite ends inside the equipment housing 1. For example... Figure 6 As shown, each adjustment assembly 8 includes cylinder 5 81 at both ends inside the equipment housing 1. Cylinder 5 81 is a vertical linear cylinder, and its cylinder body is located on the bottom surface inside the equipment housing 1. At the lower end of cylinder 5 81 (i.e., the bottom of the cylinder body), there is a connecting plate 2 82, which is a horizontal plate. At both ends of the upper surface of the connecting plate 2 82, there are vertical top posts 2 83, which are guide rods. The upper end of the top post 2 83 passes through the top wall of the equipment housing 1 and the interior of the upper platform 2 to the upper exterior of the upper platform 2, and the top of the top post 2 83 has a placement platform 84. The placement platform 84 is a horizontal plate structure. The placement platform 84 includes a large end plane positioning block and a small end plane positioning block. The large end plane positioning block is on the first layer of the large end positioning main plate, and the center of the large end plane positioning block has a large hole positioning pin pull-down hole. The small end plane positioning block is on the second layer of the small end positioning main plate, and the small end positioning pin is on the small end positioning block through left and right guide positioning posts. The fixture uses a two-pin positioning system on one side, and three planar positioning points, one of which has an air detection hole. The upper surface of the placement platform 84 has textures or grooves. The main thickness of the first layer large-end positioning main board is 25mm. The side of the second layer small-end positioning main board has a through-hole for blowing water. The second layer small-end positioning main board also has a pneumatic error prevention device.

[0035] The working state of the adjustment component 8 is as follows: the piston rod of cylinder 5 81 moves up or down, and drives the placement platform 84 to move up and down in the vertical direction through connecting plate 2 82 and top column 2 83, thus changing the height position of the placement platform 84.

[0036] The overall effect achieved by the organization is as follows: Before processing, based on the specifications of the connecting rod workpiece, the cylinder 81 of component 8 drives the top column 83 and the placement platform 84 to rise and fall, ensuring the height of the placement platform 84 matches the machining tool path. The connecting rod workpiece is placed on the placement platform 84, aligning the large and small ends of the connecting rod with their respective positioning positions on the left and right sides. The cylinder 41 of the docking device 4 is activated, causing the piston rod to move upwards via the connecting plate 42 and the top column 43, driving the push plate 44 to rise along the slide rod 33. The elastic support column 34 provides cushioning, and the positioning pin 45 rises and inserts into the positioning hole at the end of the connecting rod (the large-hole positioning pin inserts into the large-end hole, and the small-hole diamond pin inserts into the small-end hole). After positioning, the large-hole and small-hole positioning pins are pulled down by the pull-down cylinder to achieve final positioning.

[0037] Activating cylinder 4 (71) of fixing assembly 7 causes piston rod 2 (75) to push the rear end of clamping plate 74 upward. Pulled by connecting rod 2 (73), the front end of clamping plate 74 swings downward, pressing against the upper surface of the workpiece end above positioning pin 45, thus assisting in fixing the workpiece. Activating cylinder 3 (51) of clamping assembly 5 causes piston rod 1 (53) to push the rear end of U-shaped bonding block 52 upward. Limited by connecting rod 1 (54), the front end of U-shaped bonding block 52 presses downward against the upper surface of the large end of connecting rod. Simultaneously, activating oblique cylinder 55 causes bonding top rod 56 to extend obliquely, supporting the workpiece from the side. Activating bidirectional cylinder seat 6 causes positioning top rods 61 on both sides to extend, assisting in positioning the workpiece from the left and right sides.

[0038] After positioning and clamping, the connecting rod workpiece can be machined in an integrated manner, including hole machining and milling. After machining, each cylinder reverses its direction, sequentially releasing the clamping plate 74, U-shaped contact block 52, contacting ejector rod 56, and positioning ejector rod 61. The positioning pin 45 then pulls down and exits the positioning hole, allowing the machined connecting rod workpiece to be removed. The entire fixture achieves rapid positioning, reliable clamping, and integrated machining of the connecting rod workpiece.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
