Description

Technical Field

[0001] The utility model relates to the technical field of piston detection, in particular to a chain guide rail annular conveyor line for piston transfer. Background Art

[0002] The piston is a fundamental component of an engine, its very heart. Currently, automotive pistons are being developed towards high strength, high wear resistance, high precision, low expansion, lightweight construction, and modular structures. During production, pistons are transferred between various processing steps along a conveyor line. To ensure that the pistons enter the next process at the same angle, a mold is typically placed on top of the conveyor's slider. The piston fits snugly onto the mold's exterior, ensuring stability as it moves along the conveyor line. Pistons of different sizes can be manufactured simply by replacing the mold.

[0003] However, most of the molds in the prior art are detachably connected to the top of the slider of the conveyor line by bolts, which makes the disassembly and assembly process inconvenient.

[0004] Therefore, the present invention proposes a technical solution to solve the above-mentioned problem of inconvenient mold disassembly and assembly. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the utility model is to provide a chain guide ring conveyor line for piston transfer, aiming to achieve the technical effect of more convenient disassembly and assembly of the mold.

[0006] A chain guide ring conveyor line for piston transfer, comprising a bracket, a guide rail fixed to the top of the bracket and a plurality of sliders slidably connected to the guide rail, the top of the slider is detachably connected to a mold, the top of the slider is provided with two slots, the groove wall of the slot is provided with a connecting hole, the mold comprises a bottom plate, two mold bases and two insertion rods, the bottom plate is fitted to the top of the slider, the two mold bases are fixed to the top of the bottom plate in a front-to-back symmetrical shape, the two insertion rods are located between the two mold bases and are fixedly connected to the bottom plate in a left-right symmetrical shape, the bottom end of the insertion rod passes through the bottom plate and is inserted into the slot in a mating connection manner, and a sliding cavity is provided inside the sliding cavity, and the sliding connection in the sliding cavity The top end of the sliding rod is provided with a sliding hole, and the bottom end of the sliding hole is connected to the sliding hole of the sliding cavity. The sliding hole is provided with a sliding rod, and the top end of the sliding rod passes through the sliding hole and is located above the insertion rod. The bottom end of the sliding rod passes into the sliding cavity and is fixed with a pressing block, and the bottom end of the pressing block is provided with a second inclined surface matching the first inclined surface.

[0007] By adopting the above technical solution, the piston is mounted on the outside of the mold base in a matching connection manner and supported by the base plate, and two pistons can be installed on a slider. When the mold needs to be replaced according to the size of the piston, the mold disassembly process is as follows: the staff presses the slide rod downward. The slide rod moves downward along the slide hole. The slide rod drives the pressing block to move downward. The second inclined surface presses on the first inclined surface. The pressure on the first inclined surface can be decomposed into a force acting away from the connecting hole. Under the action of this force, the push block moves along the slide cavity away from the connecting hole. The first spring is compressed, forming a rebound force toward the connecting hole. The push block drives the connecting rod out of the connecting hole. Until the connecting rod retracts into the slide cavity, at this time, the insertion rod and the slot are no longer fixed, and the insertion rod is pulled upward to complete the disassembly of the mold. Similarly, the mold installation process is as follows: press the slide rod downward to retract the connecting rod into the slide cavity. Then, the bottom end of the insertion rod is inserted into the slot. When the bottom plate and the slider are in contact, the connecting rod corresponds to the connecting hole. The slider is released, and under the action of the rebound force of the first spring, the connecting rod can be inserted into the connecting hole, thereby fixing the insertion rod in the slot and completing the installation of the mold. The utility model can complete the disassembly and assembly of the mold more quickly and conveniently.

[0008] A further configuration of the present invention is that the width of the pressing block is greater than the diameter of the sliding hole.

[0009] By adopting the above technical solution, the pressing block cannot slide out of the cavity through the sliding hole, thereby preventing the sliding rod from falling off.

[0010] The utility model is further configured as follows: a cross bar is fixedly connected between the top ends of the two insertion rods, a cavity is opened inside the cross bar, the top end of the sliding rod is inserted into the cavity in a sliding connection manner, and a linkage structure for simultaneously pressing the two sliding rods downward is provided in the cavity, and the linkage structure includes a button and two rotating rods, the button corresponds to the middle part of the cross bar, the bottom end of the button is located below the cross bar, the top end of the button penetrates into the cavity in a sliding connection manner and is fixedly connected to the top cavity wall of the cavity with a second spring, the two rotating rods are both located in the cavity and are symmetrically arranged on the left and right sides of the button, the end of the rotating rod close to the button is hinged to the button, the middle part of the rotating rod is rotatably connected between the front and rear cavity walls of the cavity by a pin shaft, and the end of the rotating rod facing away from the button is fitted with the top end of the sliding rod.

[0011] Using this technical solution, a worker grasps the middle portion of the horizontal bar with one hand and presses the button. The button moves upward, compressing the second spring and generating a downward rebound force. Because one end of the rotating rod is hinged to the button, and its middle portion is pivotally connected to the front and rear walls of the cavity via a pin, the upward movement of the button causes the end of the rotating rod, which is pivotally connected to the button, to rotate upward. Simultaneously, the other end of the rotating rod rotates downward, pressing down on the slide bars, causing both slide bars to move downward simultaneously. By grasping the horizontal bar with one hand and pressing the button, the worker can simultaneously move both slide bars downward, and the horizontal bar allows the worker to more conveniently access the mold.

[0012] A further configuration of the present invention is that a pressing plate is fixed to the bottom end of the button.

[0013] By adopting the above technical solution, the setting of the pressing plate increases the force-bearing area of ​​the button, thereby improving the comfort when pressing the button.

[0014] A further configuration of the present invention is that a rubber pad is fixed on the outer side wall of the mold base.

[0015] By adopting the above technical solution, the provision of the rubber pad can, on the one hand, prevent the inner wall of the piston from being damaged by friction, and on the other hand, further enhance the stability of the piston when it is sleeved on the outside of the mold base.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model discloses a chain guide rail annular conveyor line for piston transfer, which can complete the disassembly and assembly of the mold more quickly and conveniently. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] A chain guide ring conveyor line for piston transfer, such as Figures 1-4 As shown, it includes a bracket 1, a guide rail 2 fixed to the top of the bracket 1, and a plurality of sliders 3 slidably connected to the guide rail 2. The bracket 1, the guide rail 2, and the slider 3 are mature existing technologies and are not described in detail in this embodiment. In this embodiment, a circular arc track model HOP-OV-HI can be used.

[0025] The top of the slider 3 is detachably connected to a mold. The top of the slider 3 is provided with two slots 4. The groove walls of the slots 4 are provided with connecting holes 5.

[0026] The mold consists of a base plate 6, a crossbar 7, two mold bases 8, and two insertion rods 9. The base plate 6 fits against the top of the slider 3. The two mold bases 8 are fixed to the top of the base plate 6 in a front-to-back symmetrical pattern. The two insertion rods 9 are located between the two mold bases 8 and are fixedly connected to the base plate 6 in a bilaterally symmetrical pattern. The crossbar 7 is fixedly connected between the tops of the two insertion rods 9. A cavity 10 is defined within the crossbar 7.

[0027] The bottom end of the insertion rod 9 passes through the bottom plate 6 and is inserted into the slot 4 in a mating connection manner, and a sliding cavity 11 is provided inside the sliding cavity 11. A push block 12 is slidably connected in the sliding cavity 11. A first inclined surface 13 is provided on the top end of the push block 12 on the side close to the connecting hole 5. A connecting rod 14 is fixed to the bottom end of the push block 12 on the side close to the connecting hole 5. The other end of the connecting rod 14 passes through the insertion rod 9 in a sliding connection manner and is inserted into the connecting hole 5 in a mating connection manner. A first spring 15 is fixedly connected between the other side of the push block 12 and the cavity wall of the sliding cavity 11. A sliding hole 16 is provided at the top end of the insertion rod 9. The bottom end of the sliding hole 16 is communicated with the sliding cavity 11. A sliding rod 17 is slidably connected in the sliding hole 16, and the top end of the sliding rod 17 passes into the cavity 10 in a sliding connection manner. The bottom end of the slide rod 17 penetrates into the slide cavity 11 and is fixed with a pressing block 18 . The bottom end of the pressing block 18 is provided with a second inclined surface 19 that matches the first inclined surface 13 .

[0028] A linkage structure for simultaneously pressing down the two slide bars 17 is provided in the cavity 10. The linkage structure includes a button 20 and two rotating rods 21. The button 20 corresponds to the middle part of the cross bar 7. The bottom end of the button 20 is located below the cross bar 7. The top end of the button 20 penetrates into the cavity 10 in a sliding connection manner and is fixedly connected to the top cavity wall of the cavity 10 by a second spring 22. Both rotating rods 21 are located in the cavity 10 and are symmetrically arranged on the left and right sides of the button 20. The end of the rotating rod 21 close to the button 20 is hinged to the button 20. The middle part of the rotating rod 21 is rotatably connected between the front and rear cavity walls of the cavity 10 through a pin shaft. The end of the rotating rod 21 facing away from the button 20 is attached to the top of the slide bar 17.

[0029] Additionally, a pressing plate 23 is fixed to the bottom end of the button 20. The provision of the pressing plate 23 increases the force-bearing area of ​​the button 20, thereby improving the comfort of the button 20 when pressing the button 20.

[0030] A rubber pad (not shown) is fixed to the outer wall of the die base 8. The provision of the rubber pad can prevent the inner wall of the piston from being damaged by friction, and can further enhance the stability of the piston when it is sleeved on the outside of the die base 8.

[0031] Working principle: The piston is sleeved on the outside of the mold base 8 in a matching connection manner and supported by the base plate 6. Two pistons can be installed on one slider 3.

[0032] When the mold needs to be replaced according to the piston size, the mold is disassembled as follows: the operator grasps the center of the crossbar 7 with one hand and presses the button 20. The button 20 moves upward, compressing the second spring 22 and generating a downward rebound force. Because one end of the rotating rod 21 is hinged to the button 20, and its center is pivotally connected to the front and rear walls of the cavity 10 via a pin, the upward movement of the button 20 causes the end of the rotating rod 21, which is pivotally connected to the button 20, to rotate upward. Simultaneously, the other end of the rotating rod 21 rotates downward, pressing downward on the slide rod 17, causing both slide rods 17 to move downward simultaneously along the slide hole 16. The slide rod 17 drives the pressing block 18 downward. The second inclined surface 19 presses against the first inclined surface 13. The pressure on the first inclined surface 13 can be decomposed into a force acting away from the connecting hole 5. This force causes the push block 12 to move along the slide cavity 11, away from the connecting hole 5. The compression of the first spring 15 generates a rebound force toward the connecting hole 5. The push block 12 pulls the connecting rod 14 out of the connecting hole 5 until the connecting rod 14 retracts into the sliding cavity 11. At this time, the insertion rod 9 and the slot 4 are no longer fixed. Then the staff pulls up the cross bar 7 to pull the insertion rod 9 out of the slot 4, and the mold is disassembled.

[0033] Similarly, the mold installation process is as follows: the operator grasps the middle portion of the crossbar 7 with one hand and presses the button 20, retracting the connecting rod 14 into the slide cavity 11. The bottom end of the insertion rod 9 is then inserted into the slot 4. When the base plate 6 and the slider 3 are in contact, the connecting rod 14 aligns with the connecting hole 5. The button 20 is released, and the rebound force of the first spring 15 and the second spring 22 allows the connecting rod 14 to be inserted into the connecting hole 5, thereby securing the insertion rod 9 in the slot 4 and completing the mold installation.

[0034] The utility model can complete the disassembly and assembly of the mold more quickly and conveniently.
