Description

Technical Field

[0001] This utility model relates to the field of turbocharger processing technology, specifically a positioning and clamping device for overall dynamic balancing of a turbocharger. Background Technology

[0002] A turbocharger uses the inertial force of the exhaust gas from the engine to drive a turbine in the turbine housing. The turbine then drives a coaxial impeller, which compresses the air supplied by the air filter and forces it into the cylinder, thereby increasing the engine's intake air volume.

[0003] Turbocharger dynamic balancing is a process that adjusts the mass distribution of its internal rotating components so that the rotor's axis of inertia and axis of rotation are as close as possible to each other when rotating at high speed, thereby reducing vibration and centrifugal force.

[0004] Turbochargers need to be secured during operation, but the size of the securing device is usually fixed, making it difficult to adjust in time when encountering different turbochargers, which makes the adjustment time-consuming.

[0005] Therefore, a positioning and clamping device for overall dynamic balancing of turbochargers is proposed to address the above problems. Utility Model Content

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: A positioning and clamping device for overall dynamic balancing of a turbocharger, comprising a base, a servo motor fixedly connected to the bottom of the base; a round rod fixedly connected to the output end of the servo motor; the round rod is through-hole and rotatably connected to the base; a round plate fixedly connected to the top of the round rod; multiple fixing rods slidably connected to the surface of the servo motor; the fixing rods are through-hole connected to the round plate; multiple first sliding grooves are formed on the surface of the round plate; the first sliding grooves and the fixing rods are correspondingly arranged and slidably connected; a fixing plate is fixedly connected to the top of the fixing rod; multiple first spring telescopic rods are fixedly connected inside the fixing plate; a push plate is fixedly connected to the end of each first spring telescopic rod. The base has a housing in the middle; the surface of the housing has multiple second sliding grooves; the second sliding grooves and the fixing rod are correspondingly arranged and slidably connected; by using a circular plate to drive the fixing rod to move, the turbocharger can be clamped and fixed by multiple push plates when clamping the turbocharger. The turbocharger can be pushed to the middle of the base for positioning and clamping. At the same time, when the push plate clamps the turbocharger, the first spring telescopic rod will be compressed. The higher the degree of compression of the first spring telescopic rod, the stronger the clamping of the turbocharger by the push plate. When clamping the turbocharger, the clamping force can be adjusted by the first spring telescopic rod, thereby increasing the adjustability during fixing and increasing the flexibility when clamping the turbocharger.

[0008] Preferably, the middle of the housing is rotatably connected to multiple hinged links; a support plate is fixedly connected to the top of each hinged link; a compression spring is fixedly connected to the bottom of the support plate; the compression spring and the housing are fixedly connected; by adding a support plate, the position of the middle of the base can be determined by the position of the support plate when placing the turbocharger, and then the pushing of the push plate on the turbocharger is reduced when using the push plate to fix the turbocharger, thereby performing preliminary positioning.

[0009] Preferably, a damping spring shock absorber is fixedly connected to the inner wall of the second slide groove; a baffle is fixedly connected to the end of the damping spring shock absorber; the baffle is arc-shaped; by setting the baffle to arc shape, the contact area with the fixed rod can be increased when it contacts the fixed rod, thereby reducing slippage when in contact. Subsequently, the compression of the damping spring shock absorber during movement will slow down the moving speed of the fixed rod, thereby reducing impact damage when the fixed rod contacts the second slide groove.

[0010] Preferably, a buffer pad is fixed to the top of the support plate; the buffer pad and the support plate are correspondingly arranged; by adding the buffer pad, the force of the turbocharger being lowered can be reduced by utilizing the flexibility of the buffer pad, thereby increasing the protection of the turbocharger and the support plate.

[0011] Preferably, a telescopic sleeve is fixedly connected to the bottom of the support plate; the telescopic sleeve and the base are fixedly connected; the telescopic sleeve is located in the middle of the compression spring; by adding the telescopic sleeve, the support plate can be stabilized when receiving the turbocharger, thus reducing swaying during movement.

[0012] Preferably, a plurality of brushes are fixedly connected inside the second slide groove; the brushes and the second slide groove are arranged correspondingly; by adding brushes, the second slide groove can be closed, thereby reducing the amount of impurities that enter the shell through the second slide groove and thus damage the shell.

[0013] The advantages of this utility model are:

[0014] 1. The positioning and clamping device for overall dynamic balancing of a turbocharger described in this utility model uses a circular plate to drive a fixed rod to move. When clamping the turbocharger, multiple push plates can clamp and fix the turbocharger. The turbocharger can be pushed to the center of the base for positioning and clamping. At the same time, when the push plates clamp the turbocharger, the first spring telescopic rod will be compressed. The higher the degree of compression of the first spring telescopic rod, the stronger the clamping force of the push plate on the turbocharger. When clamping the turbocharger, the clamping force can be adjusted by the first spring telescopic rod, thereby increasing the adjustability during fixation and increasing the flexibility when clamping the turbocharger.

[0015] 2. The positioning and clamping device for overall dynamic balancing of turbochargers described in this utility model can determine the position of the center of the base by adding a support plate when placing the turbocharger. Then, when using the push plate to fix the turbocharger, the pushing of the push plate on the turbocharger is reduced, thereby performing preliminary positioning. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown in the embodiment of this utility model, a positioning and clamping device for overall dynamic balancing of a turbocharger includes a base 1. A servo motor 11 is fixedly connected to the bottom of the base 1. A round rod 12 is fixedly connected to the output end of the servo motor 11. The round rod 12 is through-hole and rotatably connected to the base 1. A round plate 13 is fixedly connected to the top of the round rod 12. Multiple fixing rods 14 are slidably connected to the surface of the servo motor 11. The fixing rods 14 are through-hole connected to the round plate 13. Multiple first sliding grooves 15 are formed on the surface of the round plate 13. The first sliding grooves 15 and the fixing rods 14 are correspondingly arranged and slidably connected. 4. A fixing plate 16 is fixedly connected to the top; multiple first spring telescopic rods 17 are fixedly connected inside the fixing plate 16; push plates 18 are fixedly connected to the ends of the first spring telescopic rods 17; a housing 19 is provided in the middle of the base 1; multiple second sliding grooves 101 are opened on the surface of the housing 19; the second sliding grooves 101 and the fixing rods 14 are correspondingly arranged and slidably connected; during operation, the turbocharger is first placed on the surface of the housing 19, and then the servo motor 11 is started, causing the servo motor 11 to drive the round rod 12 to rotate. When the round rod 12 rotates, it will drive the round plate 13 to rotate. When the round plate 13 rotates, it will push the fixing rod 14. 4. Moving along the first slide groove 15, thereby moving the middle of the base 1. As the fixing rod 14 moves, it will drive the fixing plate 16 closer to the turbocharger. At the same time, the fixing plate 16 will move in place of the push plate 18. When the push plate 18 contacts the turbocharger and continues to move, it will squeeze the first spring telescopic rod 17. Then the first spring telescopic rod 17 will be compressed. When the fixing plate 16 contacts the turbocharger, it will stop moving and clamp and fix it. At the same time, the clamping force on the turbocharger can be adjusted by adjusting the compression degree of the first spring telescopic rod 17 by adjusting the fixing rod 14, thereby fixing the turbocharger. Clamping and fixing: By using the circular plate 13 to drive the fixing rod 14 to move, the turbocharger can be clamped and fixed by multiple push plates 18 when clamping the turbocharger. The turbocharger can be pushed to the middle of the base 1 for positioning and clamping. At the same time, when the push plate 18 clamps the turbocharger, the first spring telescopic rod 17 will be compressed. The higher the degree of compression of the first spring telescopic rod 17, the stronger the clamping of the push plate 18 on the turbocharger. When clamping the turbocharger, the clamping force can be adjusted by the first spring telescopic rod 17, thereby increasing the adjustability during fixing and increasing the flexibility when clamping the turbocharger.

[0026] like Figures 1 to 5As shown, the outer casing 19 is rotatably connected to multiple hinged links 2 in the middle; a support plate 21 is fixedly connected to the top of the hinged links 2; a compression spring 22 is fixedly connected to the bottom of the support plate 21; the compression spring 22 and the outer casing 19 are fixedly connected; during operation, when placing the turbocharger, the position of the support plate 21 can be observed to place the turbocharger on the support plate 21 and then lower it. When lowering, the support plate 21 will squeeze the compression spring 22 to compress it, and at the same time, the hinged links 2 will rotate, causing the support plate 21 to move downward, thereby performing initial guidance and positioning; by adding the support plate 21, the position of the middle part of the base 1 can be determined by the position of the support plate 21 when placing the turbocharger, and then when using the push plate 18 to fix the turbocharger, the pushing of the push plate 18 on the turbocharger is reduced, thereby performing initial positioning.

[0027] like Figure 5 As shown, a damping spring damper 3 is fixedly connected to the inner wall of the second slide groove 101; a baffle 31 is fixedly connected to the end of the damping spring damper 3; the baffle 31 is arc-shaped; during operation, when the fixed rod 14 moves to its longest distance, it will first contact the baffle 31. At this time, the fixed rod 14 will enter the deepest part of the fixed rod 14, thus pushing the baffle 31 during movement. At this time, the damping spring damper 3 will be compressed. Subsequently, as the fixed rod 14 moves, it gradually pushes the baffle 31 closer to the second slide groove 101, thereby reducing the impact of the fixed rod 14 on the second slide groove 101. By setting the baffle 31 to be arc-shaped, the contact area with the fixed rod 14 can be increased when it contacts the fixed rod 14, thereby reducing slippage during contact. Subsequently, the compression of the damping spring damper 3 during movement will slow down the movement speed of the fixed rod 14, thereby reducing the impact damage when the fixed rod 14 contacts the second slide groove 101.

[0028] like Figure 5 As shown, a buffer pad 4 is fixedly attached to the top of the support plate 21; the buffer pad 4 and the support plate 21 are correspondingly arranged; during operation, when the turbocharger is placed, it will first contact the buffer pad 4. Since the buffer pad 4 is flexible, it will reduce the hard contact between the turbocharger and the support plate 21 when they come into contact, thereby reducing the force when the turbocharger is lowered, thus reducing damage to the turbocharger and the hinged connecting rod 2; by adding the buffer pad 4, the flexibility of the buffer pad 4 can be used to reduce the force when the turbocharger is lowered, thereby increasing the protection of the turbocharger and the support plate 21.

[0029] like Figure 5As shown, a telescopic sleeve 5 is fixedly connected to the bottom of the support plate 21; the telescopic sleeve 5 and the base 1 are fixedly connected; the telescopic sleeve 5 is located in the middle of the compression spring 22; during operation, when the compression spring 22 drives the support plate 21 to move up and down, the telescopic sleeve 5 will provide guidance for the movement of the support plate 21, thereby reducing the shaking generated when the support plate 21 moves; by adding the telescopic sleeve 5, stability can be increased when the support plate 21 receives the turbocharger, thus reducing shaking when it moves.

[0030] like Figures 1 to 4 As shown, multiple brushes 6 are fixedly connected inside the second slide groove 101; the brushes 6 and the second slide groove 101 are arranged correspondingly; during operation, when the fixed rod 14 moves, it will contact the brushes 6, at which time the fixed rod 14 will push the brushes 6 to bend them, thereby moving them; by adding brushes 6, the second slide groove 101 can be closed, thereby reducing the amount of impurities entering the interior of the outer casing 19 through the second slide groove 101 and thus reducing damage to the interior of the outer casing 19.

[0031] Working principle: First, the turbocharger is placed on the surface of the housing 19, and then the servo motor 11 is started, causing the servo motor 11 to drive the round rod 12 to rotate. When the round rod 12 rotates, it drives the round plate 13 to rotate. When the round plate 13 rotates, it pushes the fixed rod 14 to move along the first slide groove 15, thereby moving the middle of the base 1. When the fixed rod 14 moves, it will drive the fixed plate 16 closer to the turbocharger. At the same time, the fixed plate 16 will move in place of the push plate 18. When the push plate 18 contacts the turbocharger and continues to move, it will push the first spring... The first spring telescopic rod 17 is compressed, and then the fixed plate 16 stops moving after it comes into contact with the turbocharger. At this point, the turbocharger is clamped and fixed. The clamping force on the turbocharger can be adjusted by adjusting the degree of compression of the first spring telescopic rod 17 through the fixed rod 14, thereby clamping and fixing the turbocharger. When placing the turbocharger, the position of the support plate 21 can be observed, and the turbocharger can be placed on the support plate 21 and then lowered. When lowering, the support plate 21 will compress the spring 22. The pressure compresses the pressure, and the hinged link 2 rotates, causing the supporting plate 21 to move downwards, thus providing initial guidance and positioning. When the fixed rod 14 reaches its maximum distance, it first contacts the baffle 31. At this point, the fixed rod 14 enters its deepest part, pushing the baffle 31 during movement. The damping spring shock absorber 3 compresses, and then the fixed rod 14 gradually pushes the baffle 31 closer to the second slide groove 101, thereby reducing the impact of the fixed rod 14 on the second slide groove 101. When the turbocharger is placed, it will first... When the buffer pad 4 comes into contact with the turbocharger, the rigid contact between the turbocharger and the support plate 21 is reduced due to the flexibility of the buffer pad 4. This reduces the force when the turbocharger is lowered, thus reducing damage to the turbocharger and the hinge link 2. When the compression spring 22 drives the support plate 21 to move up and down, the telescopic sleeve 5 will provide guidance for the movement of the support plate 21, thereby reducing the swaying caused by the movement of the support plate 21. When the fixed rod 14 moves, it will come into contact with the brush 6. At this time, the fixed rod 14 will push the brush 6 to bend the brush 6, thereby moving it.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
