Description

Technical Field

[0001] The present invention relates to the technical field of turbocharger housing processing, and specifically to a processing fixture for a turbocharger housing. Background Technique

[0002] The turbocharger housing adopts a casting molding process, which is the current mainstream processing method. Casting is a method of pouring molten metal into a casting cavity adapted to the shape of the part, and waiting for it to cool and solidify to obtain the part or blank. For the turbocharger housing, the casting process can meet its complex shape and structure requirements, and at the same time can ensure a certain strength and performance.

[0003] Currently, the existing turbocharger housings are processed and formed by casting molding. After casting molding, the upper mold detaches from the lower mold. At this time, the formed turbocharger housing is located in the upper mold cavity. Then, the existing receiving plate is used. After the receiving plate is moved below the upper mold, the ejection mechanism on the upper mold operates, so that the formed turbocharger housing falls onto the receiving plate. However, when the turbocharger housing is demolded, due to the pressure fluctuation of the ejection system, the ejection force is insufficient or too large. When the ejection force is insufficient, it is easy for the turbocharger housing to remain in the upper mold cavity, and when the ejection force is too large, the turbocharger housing will pop out at high speed and it is difficult to stably fall onto the receiving plate, resulting in deformation of the demolded turbocharger housing. For this reason, we propose a processing fixture for a turbocharger housing. Summary of the Invention

[0019] When the present invention is in use, through the provided material receiving fixture assembly, after the turbocharger housing is cast and formed, when the upper mold is demolded from the lower mold, the receiving plate moves below the upper mold, and the turbocharger housing is clamped and fixed by the fixed fixture mechanism. While the ejection mechanism on the upper mold is operating, the fixed fixture mechanism moves downward synchronously with the turbocharger housing for demolding. During demolding, it can achieve the function of receiving, buffering, and positioning the turbocharger housing, preventing the phenomenon that the turbocharger housing has too much ejection force and is difficult to stably fall into the receiving plate. At the same time, when the ejection mechanism fails to smoothly demold the turbocharger housing, the material receiving fixture assembly simultaneously plays a role in assisting the demolding of the turbocharger housing, further improving the demolding efficiency of the turbocharger housing.

At the same time, the push side plate 314 is semi-conical in shape;

[0043] The connecting mechanism 7 includes a connecting sleeve 71, a push inclined rod 72, a wedge-shaped block 73 and a connecting spring 74. The connecting sleeve 71 is fixedly installed inside the fixed sleeve 4, and the connecting sleeve 71 is slidably sleeved outside the lifting rod 5. An inclined opening 51 is provided on the lifting rod 5, and the push inclined rod 72 slidably penetrates through the inclined opening 51. The two ends of the push inclined rod 72 are respectively fixedly connected with a first inclined block 75 and a second inclined block 76. The connecting sleeve 71 is provided with moving openings 711 corresponding to the positions of the first inclined block 75, the second inclined block 76 and the push inclined rod 72;

[0044] There are two wedge-shaped blocks 73. Both of the two wedge-shaped blocks 73 are fixedly installed on the inner wall of the moving sleeve 8, and the two wedge-shaped blocks 73 are respectively slidably connected with the first inclined block 75 and the second inclined block 76;

[0045] The connecting spring 74 is fixedly installed at the top of the lifting rod 5, and the other end of the connecting spring 74 is fixedly connected to the moving sleeve 8. At the same time, in this embodiment, the connecting spring 74 is always in a compressed state.

[0046] Two limiting grooves 81 are provided on the outside of the moving sleeve 8, and two limiting strips 41 are provided on the inner wall of the fixed sleeve 4. The two limiting strips 41 are respectively slidably connected with the two limiting grooves 81.

[0047] The bottom of the fixed sleeve 4 is provided with two clamping holes 42, and two clamping rods 43 slide through the two clamping holes 42. Two positioning holes 82 are provided on the outer side of the moving sleeve 8. One end of the clamping rod 43 located outside the clamping hole 42 is fixedly connected with a clamping plate 44. Two support rods 45 slide through both ends of the clamping plate 44. One end of the support rod 45 is fixedly connected with the outer wall of the fixed sleeve 4, and a limiting plate 46 is fixedly connected between the other ends of the two support rods 45. A support spring 47 is sleeved on the outer side of the support rod 45. One end of the support spring 47 is fixedly connected with the fixed sleeve 4, and the other end of the support spring 47 is fixedly connected with the clamping plate 44.

[0048] Specific implementation process: When the turbocharger housing is cast and formed between the upper mold and the lower mold, the upper mold is separated from the lower mold, and the formed turbocharger housing is located in the cavity of the upper mold. At this time, the bottom of the lifting rod 5 is located at the lifting section of the lifting block 62. At this time, the lifting rod 5 moves up to the highest position relative to the fixed sleeve 4. Due to the connection of the first inclined block 75 and the second inclined block 76 at both ends of the pushing inclined rod 72, the moving sleeve 8 moves down along the fixed sleeve 4 through the two wedge-shaped blocks 73. At this time, the two clamping rods 43 at the fixed sleeve 4 are respectively clamped at the two positioning holes 82 on the moving sleeve 8 under the connection of the support spring 47.

[0049] Until the fixed clamping mechanism 9 of the receiving plate 1 moves to directly below the turbocharger housing, by rotating the motor 61 by 180°, the annular lifting step 621 on the lifting block 62 rotates synchronously relative to the lifting rod 5, and the descending section rotates to the bottom of the lifting rod 5. The lifting rod 5 moves down along the fixed sleeve 4 under the reverse elastic force of the connecting spring 74. When the lifting rod 5 moves down, the inclined opening 51 on it moves relative to the pushing inclined rod 72. At this time, the pushing inclined rod 72 is limited by the inclined opening 51 and drives the first inclined block 75 and the second inclined block 76 at its two ends to move horizontally relative to the moving port 711 of the connecting sleeve 71. When the first inclined block 75 and the second inclined block 76 move synchronously, they simultaneously push the two wedge-shaped blocks 73 inside the moving sleeve 8, and under the reverse elastic force of the connecting spring 74, the moving sleeve 8 moves up relative to the fixed sleeve 4. When the moving sleeve 8 moves up, the fixed clamping mechanism 9 at the top of the moving sleeve 8 moves to the turbocharger housing to clamp and fix the turbocharger housing.

[0050] While the fixed fixture mechanism 9 fixes the turbocharger housing, in order to prevent the fixed fixture mechanism 9 from moving relative to the turbocharger housing, the first electric push rod 311 operates, so as to push the push block 313 through the push rod 312. Then the push block 313 pushes the push side plate 314 to position the push side plate 314, and further position the lifting rod 5, thus preventing the lifting rod 5 from moving;

[0051] Until the fixed fixture mechanism 9 fixes the turbocharger housing in a way of expanding and fixing, at this time, on the one hand, the first electric push rod 311 retracts, so that the push block 313 disengages from the push side plate 314. At this time, the fixed fixture mechanism 9 and the turbocharger housing are kept in a fixed integrated form;

[0052] On the other hand, the ejection mechanism on the upper mold operates, so that the turbocharger housing disengages from the upper mold cavity. When the ejection is smooth, the turbocharger housing moves downward along the fixed sleeve 4 together with the fixed fixture mechanism 9, and the moving sleeve 8 moves downward synchronously until the two clamping rods 43 clamp and fix the moving sleeve 8, thereby preventing the turbocharger from having unstable demolding and preventing the turbocharger housing from being knocked and deformed during demolding;

[0053] And when the turbocharger housing cannot be stably demolded, the rotation motor 61 operates, so that the lifting block 62 rotates relative to the bottom of the lifting rod 5 through the annular lifting step 621 thereon, so that the lifting rod 5 moves upward. While the lifting rod 5 moves upward, through the movement of the inclined opening 51, the first inclined block 75 and the second inclined block 76, the moving sleeve 8 moves downward, further stably disengaging the turbocharger housing fixed to the fixed fixture mechanism 9 from the upper mold.

[0054] Please refer to Figures 2 to 6 , the fixed fixture mechanism 9 includes a support frame 91, a rotating shaft 92, a clamping member 93 and a synchronous driving member 94. The support frame 91 is fixedly installed on the top of the moving sleeve 8, and there are three support ends on the support frame 91. There are three rotating shafts 92, and the rotating shafts 92 are rotatably connected to the support ends. The clamping member 93 is connected to the rotating shaft 92, and the synchronous driving member 94 is installed on the support frame 91, and the synchronous driving member 94 is used to synchronously drive the three rotating shafts 92.

[0055] The clamping member 93 includes an extension plate 931, an extension rod 932, and an abutting block 933. There are two extension plates 931. One end of each of the two extension plates 931 is fixedly sleeved outside the rotating shaft 92, and the other end of the two extension plates 931 is fixedly sleeved outside the extension rod 932. The abutting block 933 is installed on the top of the extension rod 932. The abutting block 933 is set in a cylindrical shape. At the same time, an anti-slip sleeve can be provided on the outside of the abutting block 933, so as to ensure that the abutting block 933 can be fixedly supported inside the turbocharger housing and prevent the phenomenon that the abutting block 933 moves relative to the turbocharger housing.

[0056] The synchronous driving member 94 includes a synchronous gear 941, a synchronous belt 942, a connecting plate 943, and a moving member 944. There are three synchronous gears 941. The three synchronous gears 941 are respectively fixedly sleeved outside the three rotating shafts 92. The synchronous belt 942 is used to drive the three synchronous gears 941. The synchronous belt 942 is provided with a connection port 9421, and both ends of the connection port 9421 are fixedly connected with a U-shaped connecting plate 943. The moving member 944 is installed on the support frame 91, and the moving member 944 is used to connect the two connecting plates 943.

[0057] The moving member 944 includes a connecting sleeve 9441, a connecting rod 9442, and a second electric push rod 9443. The connecting sleeve 9441 is fixedly installed on the support frame 91. There are two connecting rods 9442. The two connecting rods 9442 respectively slide through both ends of the connecting sleeve 9441. A synchronous plate is fixedly connected between the two connecting rods 9442. The other end of the connecting rod 9442 is rotatably connected to the connecting plate 943 through a pin shaft. The connecting sleeve 9441 is provided with a connection port 9421, and the synchronous plate slides through the connection port 9421. The second electric push rod 9443 is fixedly installed on the support frame 91, and the output end of the second electric push rod 9443 is fixedly connected to the synchronous plate;

[0058] Specific implementation process: When the moving sleeve 8 moves upward, the tops of the three abutting blocks 933 are all in contact with the turbocharger housing. Then, by operating the second electric push rod 9443, the synchronous plate moves relative to the connection port 9421. When the synchronous plate moves, it drives the two connecting rods 9442 on both sides of it to move synchronously. When the two connecting rods 9442 move, it occurs at the connection port 9421 of the synchronous belt 942, that is, one end of the connection port 9421 is subjected to a tensile force, and the other end of the connection port 9421 is subjected to a thrust force, so that the synchronous belt 942 moves relative to the three synchronous gears 941. When the synchronous belt 942 moves, it drives the three synchronous gears 941 to rotate synchronously. When the three synchronous gears 941 rotate, they drive the three rotating shafts 92 to rotate synchronously. When the rotating shafts 92 rotate, the abutting blocks 933 are driven by the extension plates 931 and the extension rods 932 to abut and fix the turbocharger housing, that is, the three abutting blocks 933 act to support and fix each other at the inner circle of the turbocharger housing, thereby realizing the function of fixing and clamping the turbocharger housing.

[0059] Embodiment 2

[0060] Please refer to Figures 13 to 15 , Embodiment 2 is a further supplementary description of Embodiment 1. Specifically, a support frame 10 is slidably sleeved on the outer side of one end of the material receiving plate 1, and a lateral driving assembly 101 for laterally driving the material receiving plate 1 is provided on the support frame 10. In this embodiment, the lateral driving assembly 101 is composed of a motor and a lead screw. That is, the lead screw is rotatably connected to the support frame 10, and the material receiving plate 1 is threadedly sleeved on the outer side of the lead screw. At the same time, the motor is used to drive the lead screw;

[0061] Furthermore, by operating the motor, the lead screw rotates relative to the support frame 10, thereby providing a lateral driving force for the material receiving plate 1. At the same time, under the limiting action of the support frame 10 on the material receiving plate 1, the material receiving plate 1 moves along below the upper die;

[0062] At the same time, a lifting frame 102 is provided on the outer side of the support frame 10, and a lifting mechanism 103 is provided on the lifting frame 102. The lifting mechanism 103 is composed of an existing motor and a lead screw, and is used to adjust the height of the support frame 10 in the vertical plane, thereby realizing the function of adjusting the material receiving plate 1 in the vertical direction, so that the material receiving fixture assembly 2 on the material receiving plate 1 stably receives the turbocharger housing.
