Description

Technical Field

[0001] The present invention relates to the technical field of metal surface treatment, in particular to a device for heat treating the inner surface of a stator of a high-speed common rail vane pump. Background Art

[0002] The stator is the stationary part of an electric motor or generator. In a high-speed common rail vane pump, a stator is needed to generate a rotating magnetic field. During the production process, the inner surface of the stator needs to be heat-treated to allow nitrogen to penetrate into its inner surface, thereby forming a hard protective layer to protect the stator. In order to facilitate the heat treatment of the inner surface, the stator is generally placed on the outside of a heating rod for heating. When in use, the existing heat treatment device cannot correct the position between the stator and the heating rod, resulting in differences in the distance between the stator and the heating rod at different locations, resulting in differences in the heat treatment degree of the stator, resulting in a decrease in the quality of the stator, which is not conducive to the heat treatment of the stator. At the same time, during the heat treatment process of the stator, there is a lack of ability to clean the slag on the inner surface of the stator. The slag remains on the inner wall of the stator, which will affect the nitrogen penetration. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose a high-speed common rail vane pump stator inner surface heat treatment device.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A high-speed common rail vane pump stator inner surface heat treatment device includes a heating furnace shell, a driver is installed on the lower inner wall of the heating furnace shell, the output end of the driver is fixedly connected to a rotating rod, the top end of the rotating rod is fixedly connected to a heating rod, and the lower inner wall of the heating furnace shell is fixedly connected to a placement plate via a support frame, and the placement plate is sleeved on the outside of the rotating rod and the heating rod; The adjusting device is a device for adjusting the position of the adjusting member, and the adjusting member is a chain which is connected to the guide rail of the adjusting member and is arranged on a track to guide the adjusting member to move relative to the guide rail.

[0005] The top end of the connecting gear is fixedly connected to the outer surface of the adjusting rod, and the upper end of the connecting gear is engaged with the gear of the adjusting rod and the lower end of the adjusting rod.

[0006] Preferably, the knocking rod is an elastic telescopic structure.

[0011] Compared with the prior art, the present invention has the following beneficial effects: By rotating the inner correction plate, the stator rotates accordingly and cooperates with the outer correction plate outside the stator to perform real-time correction on the position of the stator, so that the distance between each part of the stator and the heating rod is equal. At the same time, the inner correction plate moves upward to correct the stator on the vertical plane, thereby improving the effect of position correction. At the same time, the outer positioning plate can move back and forth, further improving the correction ability, avoiding differences in the heat treatment degree of the inner surface of the stator, thereby improving the overall quality of the stator and facilitating the heat treatment. When the correction plate rotates, the connecting gear rotates back and forth, causing the connecting disk to rotate, so that the knocking rod and knocking block installed on the connecting disk continuously knock on the inner surface of the stator, breaking and shaking off the slag remaining on the inner surface of the stator, and preventing the slag from adhering to the stator, affecting the heat treatment and nitriding of the stator, and causing the quality of the stator to deteriorate; The fixed nozzle that sprays nitrogen moves upward together with the correction plate, and the upward movement is intermittent. In conjunction with the rotation of the stator, the fixed nozzle can spray nitrogen more evenly onto the inner surface of the stator, which is beneficial to the nitrogen permeation and the heat treatment of the stator.

DETAILED DESCRIPTION

[0014] See Figures 1-8 , a high-speed common rail vane pump stator inner surface heat treatment device, including a heating furnace shell 1, the lower inner wall of the heating furnace shell 1 is installed with a driver, the output end of the driver is fixedly connected to a rotating rod 3, the top of the rotating rod 3 is fixedly connected to a heating rod 4, the driver drives the rotating rod 3 to rotate, so that the heating rod 4 rotates accordingly, the lower inner wall of the heating furnace shell 1 is fixedly connected to a placing plate 2 through a support frame, the placing plate 2 is sleeved on the outer side of the rotating rod 3 and the heating rod 4, the stator is placed on the placing plate 2, the inner wall is heated by the heating rod 4, and nitrogen is allowed to penetrate into the inner wall, so that a hard protective layer is formed on the inner wall. This method is a conventional stator surface heat treatment method, so it will not be described in detail; like Figure 3 、 Figure 4 and Figure 5 The cam 62 is fixed to the side wall of the mounting ring 61 and is fixed to the inner and outer cams 64 and 66 respectively, and the bottom end of the inner and outer cams 64 is slidably connected to the annular plate 69. The surface of the mounting plate 2 is smooth, so the friction between the stator and the mounting plate 2 is small. The friction between the inner and outer cams 64 and the stator can drive the stator to rotate, while the friction between the inner and outer cams 64 and the stator is not enough to overcome the gravity of the stator. Therefore, when the inner and outer cams 64 move up and down, the stator will not move accordingly. Figure 3The inner correction plate 64 can slide linearly in the left and right directions on the annular plate 69. A reciprocating screw sleeve 68 is rotatably connected to the heating furnace shell 1. The inner side of the reciprocating screw sleeve 68 is mechanically matched with a screw slider. An adjusting rod 67 is fixedly installed on the screw slider. The adjusting rod 67 is limited by the sliding bracket 610 and cannot rotate. Therefore, when the reciprocating screw sleeve 68 rotates, the adjusting rod 67 can reciprocate up and down relative to the sliding bracket 610. The annular plate 69 is installed with a transmission structure through the connecting bracket 617. The adjusting rod 67 is fixed by the sliding bracket 610. The movable bracket 610 is fixedly connected to the placement plate 2, and the sliding bracket 610 is slidably sleeved on the outer side of the adjustment rod 67. The sliding bracket 610 limits the adjustment rod 67 so that it cannot rotate without affecting the up and down movement of the adjustment rod 67. A mounting block 612 is fixedly sleeved on the adjustment rod 67, and a fixed pipe 614 is fixedly connected to the side wall of the mounting block 612. The fixed pipe 614 is connected to the nitrogen pump through a hose. A fixed nozzle 613 communicating with the fixed pipe 614 is fixedly installed on the mounting block 612, and a cleaning structure 7 is installed on the adjustment rod 67. When the heating rod 4 rotates, the mounting ring 61 and the corresponding correction rod 63 and inner correction plate 64 rotate, causing the stator to rotate accordingly, and cooperate with the outer correction plate 66 to correct the position of the stator so that the distance between the stator and the heating rod 4 is the same, so that the stator is heated more evenly and the stator heat treatment effect is better. At the same time, as the inner correction plate 64 rotates, the connecting bracket 617 and the transmission structure operate accordingly, causing the adjustment rod 67 to rise intermittently. During the rising process of the adjustment rod 67, the nitrogen pump pumps nitrogen from the fixed pipe 614 and then sprays it from the fixed nozzle 6134. In conjunction with the rotation of the stator, nitrogen is sprayed on various parts of the inner wall of the stator to facilitate the nitrogen to penetrate into the inner wall of the stator. In addition, the movement of the inner correction plate 64 can also perform real-time correction of the position of the stator on the vertical plane. like Figure 6 、 Figure 7 and Figure 8As shown, the cleaning structure 7 includes a connecting plate 71 that is rotatably sleeved on the adjusting rod 67. The side wall of the connecting plate 71 is fixedly connected to a connecting rod 72. The connecting rod 72 extends to the position of the connecting bracket 617. When the connecting bracket 617 moves to the connecting rod 72, the connecting rod 72 is squeezed to rotate with the connecting plate 71 as the center until the connecting bracket 617 is separated from the connecting rod 72. The bottom end of the connecting plate 71 is fixedly connected to a connecting gear 74, and the connecting gear 74 is sleeved on the outside of the adjusting rod 67. The connecting gear 74 is not connected to the adjusting rod 67. The bottom end of the mounting block 612 is supported by a gear. The bracket is rotatably connected to a connecting shaft 76. The top end of the connecting shaft 76 is fixedly connected to a mounting gear 75, and the mounting gear 75 meshes with the connecting gear 74. The gear bracket is "L"-shaped, does not contact the connecting plate 71, and extends from one side of the connecting plate 71 to the bottom of the connecting plate 71. The diameter of the connecting gear 74 is larger than the mounting gear 75. By setting the gear transmission ratio, the connecting gear 74 can rotate a small arc to make the mounting gear 75 rotate one circle. The bottom end of the connecting shaft 76 is fixedly connected to a connecting disk 77. The bottom end of the connecting disk 77 is fixedly connected to the mounting shaft 78. The mounting shaft 78 The outer side of the knock rod 79 is rotatably sleeved, and the end face of the knock rod 79 is fixedly connected to the knock block. The knock rod 79 is slidably sleeved with a sliding sleeve, and the sliding sleeve is rotatably connected to the rotating bracket 710. The knock rod 79 is an elastic telescopic structure, and the sliding sleeve is installed at the telescopic end of the knock rod 79. When the knock block knocks the inner wall of the stator, the knock rod 79 will contract, and the sliding sleeve will slide on the knock rod 79 to ensure that the position of the sliding sleeve relative to the connecting plate 71 remains unchanged. At the same time, when the mounting shaft 78 rotates with the connecting disk 77, the end of the knock rod 79 connected to the mounting shaft 78 will move accordingly. At this time, the sliding sleeve can act as a fulcrum, so that the other end of the knocking rod 79 moves in the opposite direction. The rotating bracket 710 is rotatably connected to the sliding sleeve so that the sliding sleeve rotates with the knocking rod 79 to avoid interference between the movement of the sliding sleeve and the knocking rod 79. The rotating bracket 710 is fixedly connected to the bottom end of the mounting block 612. A torsion spring 73 is fixedly connected between the connecting plate 71 and the mounting block 612. The torsion spring 73 is sleeved on the outer side of the adjusting rod 67. The torsion spring 73 can reset the connecting plate 71. The knocking rod 79 is an elastic telescopic structure to avoid damage to the knocking block. When the connecting bracket 617 is rotated, it squeezes the connecting rod 72 to make it rotate around the connecting plate 71 until the connecting bracket 617 is separated from the connecting rod 72 and the torsion spring 73 is deformed. When the connecting bracket 617 is separated from the connecting rod 72, the elastic force of the torsion spring 73 makes it return to its original position. During the rotation of the connecting rod 72 and the connecting plate 71, the connecting plate 71 drives the connecting gear 74 to rotate, so that the mounting gear 75 meshing with the connecting gear 74 rotates, causing the connecting shaft 76 and the connecting plate 77 to rotate. When the connecting plate 77 rotates, one end of the knocking rod 79 moves accordingly. The knocking rod 79 uses the sliding sleeve as a fulcrum to knock on the inner wall of the stator, thereby breaking off the slag on the surface of the stator during the heat treatment process and cleaning it to facilitate the heat treatment. like Figure 3 and Figure 4 As shown, the transmission structure includes a fixed gear 611 fixedly sleeved on the outside of the reciprocating screw sleeve 68, the top of the adjusting rod 67 is against the annular plate 69, and the adjusting rod 67 is not connected to the annular plate 69. The upward movement of the adjusting rod 67 can push the annular plate 69 to move together, and the bottom end of the connecting bracket 617 is fixedly connected to the arc rack 65. The connecting bracket 617 is a telescopic structure, and the arc rack 65 is meshed with the fixed gear 611. The bottom end of the arc rack 65 is fixedly connected to a support rod, and the support rod is slidably connected to the lower inner wall of the heating furnace shell 1. The support rod can rotate with the arc rack 65, that is, the support rod can slide in an annular manner on the lower inner wall of the heating furnace shell 1. The support rod cooperates with the connecting bracket 617 to ensure that the arc rack 65 is always located in the same plane as the fixed gear 611, and the two can mesh; The connecting bracket 617 drives the arc-shaped rack 65 to rotate. When the arc-shaped rack 65 rotates, it meshes with the fixed gear 611, causing the fixed gear 611 to rotate until the two separate. As a result, the fixed gear 611 rotates intermittently, causing the reciprocating screw sleeve 68 connected to the fixed gear 611 to rotate intermittently. like Figure 3 As shown, the bottom end of the side plate 62 extends to the bottom of the placement plate 2, and the side wall of the side plate 62 is fixedly connected to a deflection rod 8, and the end face of the deflection rod 8 is fixedly connected to a deflection block 5. The position of the deflection block 5 matches the arc-shaped rack 65. A rotating support rod 9 is rotatably sleeved on the deflection rod 8, and the rotating support rod 9 is fixedly connected to the placement plate 2; the deflection rod 8 is a telescopic structure, and the telescopic end of the deflection rod 8 is located between the rotating support rod 9 and the side plate 62, so as to avoid conflict between the movement of the deflection rod 8 and the movement of the side plate 62, which may cause damage to the components; When the arc-shaped rack 65 rotates to the position of the deflection block 5, the rotation of the arc-shaped rack 65 will cause the deflection block 5 to rotate accordingly, causing the deflection rod 8 fixedly connected to the deflection block 5 to rotate together, and cooperate with the rotating support rod 9 to drive the side plate 62 to move. The side plate 62 can be reset after moving, so that it can move back and forth to further correct the position of the stator; like Figure 4 As shown, the side wall of the mounting block 612 is fixedly connected with a control button 615, which corresponds to the nitrogen pump. The connecting bracket 617 is fixedly connected with an extrusion plate 616, and the position of the extrusion plate 616 matches the control button 615. The control button 615 and the nitrogen pump are matching existing equipment. Under normal conditions, the nitrogen pump does not run. After the control button 615 is pressed, the nitrogen pump will start for a period of time, so that nitrogen is pumped out by the nitrogen pump within a certain period of time. The control button 615 is elastic and can be operated. Automatic reset. This control button 615 is an existing control switch structure, so it will not be described in detail. As the connecting bracket 617 rotates, the squeezing plate 616 rotates accordingly. The squeezing plate 616 squeezes the control button 615 when rotating, thereby pressing the control button 615, causing the nitrogen pump to run for a period of time. The nitrogen pump pumps out nitrogen. At the same time, as the squeezing plate 616 rotates, the squeezing plate 616 separates from the control button 615. At this time, the control button 615 is reset. Therefore, after a period of time, the nitrogen pump stops running.

[0015] In the present invention, when the device is in use, the stator is first placed on the placement plate 2, and its inner wall is heated by the heating rod 4. Then, the driver is started, and the driver drives the rotating rod 3 to rotate, so that the heating rod 4 rotates accordingly. When the heating rod 4 rotates, the mounting ring 61 and the corresponding correction rod 63 and the inner correction plate 64 rotate, so that the stator rotates accordingly, and cooperates with the outer correction plate 66 to correct the position of the stator so that the distance between the stator and the heating rod 4 is the same, so that the stator is heated more evenly and the heat treatment effect of the stator is better. At the same time, as the inner correction plate 64 rotates, the annular plate 69 and the connecting bracket 617 rotate, thereby driving the arc-shaped rack 65 to rotate. When the arc-shaped rack 65 rotates, it meshes with the fixed gear 611, causing the fixed gear 611 to rotate until the two are separated. Therefore, the fixed gear 611 rotates intermittently, causing the adjustment rod 67 to rise intermittently. When the adjustment rod 67 rises, it pushes the annular plate 69 and the inner correction plate 64 to move upward. The upward movement of the inner correction plate 64 can also correct the position of the stator in real time on the vertical plane. At the same time, when the arc-shaped rack 65 rotates to the position of the deflection block 5, the rotation of the arc-shaped rack 65 will cause the deflection block 5 to rotate accordingly, so that the deflection rod 8 fixedly connected to the deflection block 5 rotates together, and cooperates with the rotating support rod 9 to drive the side plate 62 to move. The side plate 62 can be reset after moving, so that it can move back and forth to further correct the position of the stator; When the locking cam 73 is unlocked, the locking cam 73 is unlocked, and the locking cam 73 is unlocked, so that the master lock 71 is unlocked, and the master lock 71 is unlocked, so that the master lock 71 is unlocked. In addition, during the rising process of the adjustment rod 67, the rotation of the connecting bracket 617 will drive the extrusion plate 616 to rotate accordingly. When rotating, the extrusion plate 616 will squeeze the control button 615, thereby pressing the control button 615, causing the nitrogen pump to run for a period of time. The nitrogen pump pumps out nitrogen and then sprays it out from the fixed nozzle 613. In conjunction with the rotation of the stator, nitrogen is sprayed on various parts of the inner wall of the stator, so that the nitrogen can penetrate into the inner wall of the stator, forming a hard protective layer on the inner wall during the heat treatment process.
