Description

Technical Field

[0001] This utility model relates to the field of deposition processing equipment technology, and in particular to a deposition processing equipment for CrN coating on a common rail valve plate. Background Technology

[0002] The common rail valve plate is a core component of the high-pressure common rail fuel injection system. It is mainly used to precisely control the fuel injection process. In the production process of the common rail valve plate, one or more layers of CrN coating need to be added to the surface of the common rail valve plate using vapor deposition equipment. This significantly reduces friction and wear during the fuel injection process and extends the valve plate's life.

[0003] Existing vapor deposition equipment for depositing CrN coatings on common rail valve plates involves placing the common rail valve plate inside a furnace, then using internal resistance heating to evaporate the CrN plating material, transforming the solid material into gaseous atoms or molecules. The vaporized particles migrate in a vacuum environment, colliding with inert gases (such as argon) to generate plasma. Some particles are ionized, and then deposited onto the surface of the common rail valve plate under the drive of an electric field or thermal energy, forming a dense film, thereby achieving the deposition of CrN coatings on the common rail valve plate.

[0004] However, due to the limited operating space inside the furnace, it may be necessary for personnel to remove the common rail valve plate from the furnace in batches, which is cumbersome and time-consuming, affecting the efficiency of personnel loading and unloading materials. Utility Model Content

[0005] The technical problem this utility model aims to solve is that, due to the limited operating space inside the furnace, personnel may need to remove the common rail valve plate from the furnace in batches, which is cumbersome and time-consuming, affecting the efficiency of personnel loading and unloading materials.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a common rail valve plate CrN coating deposition processing equipment, comprising: a furnace body, which is placed on the ground for loading and processing common rail valve plates and coating raw materials; a furnace cover, which is set on the furnace body for sealing the deposition chamber of the furnace body; and a material handling device, wherein the material handling device is placed inside the deposition chamber of the furnace body for carrying and removing the common rail valve plates.

[0007] Preferably, the material handling device includes: a concave plate fixedly connected to the inside of the furnace body, wherein a slide rail is provided on the concave plate; a perforated block, wherein a pull rod is fixedly connected to one side of the perforated block, wherein the perforated block is slidably installed inside the slide rail of the concave plate, wherein the cross-section of the perforated block and the slide rail are both cross-shaped; and a storage frame, wherein the storage frame is placed inside the concave plate and fixed to the perforated block by a pin, wherein the storage frame is used to store the common rail valve plate.

[0008] The effect achieved by the above components is as follows: By setting up a material handling device, the storage frame is first manually moved to move the pin. When the storage frame moves to the position where the pin inserts into the hole block, the storage frame is placed inside the concave plate and fixed to the hole block. At this time, the common rail valve plate is placed inside the storage frame, and the pull rod is manually pushed to move the hole block and the storage frame. When the storage frame moves to the position where it is completely inside the concave plate, the storage frame brings the common rail valve plate into the furnace body, completing the feeding of the common rail valve plate. After the common rail valve plate is processed, then... Pulling the lever again removes the storage frame from the furnace body, separating it from the perforated block. This allows the storage frame to carry the processed common rail valve plate out of the furnace, enabling rapid retrieval of the common rail valve plate. This allows personnel to load and unload the common rail valve plate from outside the furnace, increasing the operational space and reducing the cumbersome and time-consuming process of manually removing or placing the common rail valve plate in batches due to limited space, which affects the efficiency of loading and unloading. This significantly improves the convenience of loading and unloading.

[0009] Preferably, the storage frame is provided with multiple rollers on the side near the pin, wherein the multiple rollers are rotatably mounted on the storage frame via bearing rods, and the surface of the rollers is in contact with the inner wall of the concave plate.

[0010] The effect achieved by the above components is that the rollers can provide auxiliary support for the storage frame, and the friction between the storage frame and the inner wall of the concave plate can be reduced by the rotation of the rollers.

[0011] Preferably, the material handling device further includes: a perforated plate fixedly connected to the storage frame, wherein a positioning rod is slidably connected to the inner wall of the perforated plate; and two intercepting plates slidably installed in the storage frame, wherein the positioning rod is fixed to the perforated plate and the intercepting plates by inserting into the interior of the perforated plate and the intercepting plates.

[0012] The effect achieved by the above components is as follows: by setting up the interceptor plates, the personnel first manually move the interceptor plates so that the interceptor plates move left and right along the inside of the storage frame. When the two interceptor plates move to a position where the distance between them matches the size of the common rail valve plate, the two positioning rods are manually inserted into the perforated plate and the two interceptor plates respectively to fix the two interceptor plates. This allows the two interceptor plates to limit the common rail valve plate placed inside the storage frame, reducing the possibility of the common rail valve plate sliding or tipping over during the pushing process, which could cause collision and wear between the common rail valve plates or with the inner wall of the storage frame.

[0013] Preferably, the inner wall of the storage frame is fixedly connected with a directional rod, wherein the directional rod is placed inside the two intercepting plates.

[0014] The effect achieved by the above components is that by setting the directional rod, the directional rod can be placed inside the two interceptor plates to limit their movement, thereby reducing the possibility of the two interceptor plates tilting during use and affecting the limiting effect on the common rail valve plate.

[0015] Preferably, a spring shaft is fixedly connected to one side of each of the two interceptor plates, wherein the spring shaft has two return springs, and two auxiliary plates are slidably connected to the surface of the spring shaft, wherein the two auxiliary plates are respectively fixedly connected to the two return springs.

[0016] The effect achieved by the above components is as follows: by setting auxiliary plates, under the reaction force of the return spring, the two return springs on the spring shaft push the two auxiliary plates to move closer to each other. When the two auxiliary plates move closer to the position where they are in contact with the surface of the common rail valve plate, the two auxiliary plates assist in intercepting the common rail valve plate on the other two sides, further improving the limiting effect on the common rail valve plate.

[0017] Preferably, it further includes: a support assembly, the support assembly comprising: a perforated plate, the perforated plate being fixedly connected to the concave plate on the side away from the storage frame; an L-shaped rod, wherein the L-shaped rod is slidably mounted on the perforated plate by a spring rod, wherein the other end of the spring rod is fixedly connected to the perforated plate, and wherein the short arm end of the L-shaped rod is in contact with the surface of the storage frame.

[0018] The effect achieved by the above components is as follows: by setting up the support components, when the storage frame moves out of the furnace body, the storage frame pushes the L-shaped rod to move away from the inside of the furnace body, causing the L-shaped rod to pull the spring rod to move along the inside of the circular hole plate, so that the L-shaped rod follows the movement of the storage frame and supports the bottom of the storage frame during the movement, thereby achieving support and reinforcement of the storage frame, reducing the possibility of the storage frame falling off the side away from the circular hole block after it moves out of the furnace body, and improving the stability of the storage frame.

[0019] Preferably, a support plate is fixedly connected to the inner side of the L-shaped rod, and the surface of the support plate is trapezoidal.

[0020] The effect achieved by the above components is that by setting up a support plate, the inner side of the L-shaped rod can be supported and reinforced, reducing the swaying or tilting of the L-shaped rod during use.

[0021] The beneficial effects of this utility model are:

[0022] By setting up a material handling device, personnel can load and unload the common rail valve plate outside the furnace, increasing the operating space for personnel. This reduces the cumbersome and time-consuming process of having to remove or place the common rail valve plate in batches due to limited operating space, which affects the efficiency of loading and unloading. This improves the convenience of loading and unloading. Attached Figure Description

[0030] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Figure 1-5 The common rail valve plate CrN coating deposition processing equipment shown includes: a furnace body 1, which is placed on the ground for loading and processing common rail valve plates and coating raw materials; a furnace cover 2, which is set on the furnace body 1 for sealing the deposition chamber of the furnace body 1; and a material handling device 3, which is placed inside the deposition chamber of the furnace body 1 for carrying and removing the common rail valve plates.

[0033] Figure 2 , Figure 3 and Figure 4The material handling device 3 shown includes: a concave plate 31, which is fixed inside the furnace body 1, and has a slide rail on it; a perforated block 32, with a pull rod 33 fixed to one side of the perforated block 32, which is slidably installed inside the slide rail of the concave plate 31, and both the perforated block 32 and the slide rail have a cross-shaped cross-section; and a storage frame 34, which is placed inside the concave plate 31 and fixed to the perforated block 32 by a pin 35. The storage frame 34 is used to store the common rail valve plate. By setting up the material handling device 3, the storage frame 34 is first manually moved to move the pin 35. When the storage frame 34 moves to the position where the pin 35 is inserted into the perforated block 32, the storage frame 34 is placed inside the concave plate 31 and fixed to the perforated block 32. At this time, the common rail valve plate is placed inside the storage frame 34 and the pull rod 33 is manually pushed. Rod 33 moves the perforated block 32 and the storage frame 34. When the storage frame 34 moves to the position where it is fully inside the concave plate 31, it brings the common rail valve plate into the furnace body 1, completing the loading of the common rail valve plate. After the common rail valve plate is processed, the rod 33 is pulled again to pull the storage frame 34 out of the furnace body 1 and separate the storage frame 34 from the perforated block 32, so that the storage frame 34 brings the processed common rail valve plate out of the furnace body 1 together. This achieves rapid material handling of the common rail valve plate, allowing personnel to load and unload the common rail valve plate from outside the furnace body 1. This increases the operating space for personnel and reduces the cumbersome and time-consuming process of having to take out or put in the common rail valve plate in batches due to limited operating space, which affects the efficiency of loading and unloading. This improves the convenience of loading and unloading.

[0034] Figure 2 and Figure 3The storage frame 34 shown has multiple rollers 36 on the side near the pin 35. These rollers 36 are rotatably mounted on the storage frame 34 via bearing rods. The surfaces of the rollers 36 are in contact with the inner wall of the concave plate 31. The rollers 36 provide auxiliary support for the storage frame 34 and reduce friction between the storage frame 34 and the inner wall of the concave plate 31 due to their rotation. The material handling device 3 also includes: a perforated plate 37 fixed to the storage frame 34, with a positioning rod 38 slidably connected to the inner wall of the perforated plate 37; and two intercepting plates 39 slidably mounted in the storage frame 34. The positioning rods 38 are connected via bearing rods. The perforated plate 37 and the interceptor plate 39 are inserted inside to fix the common rail valve plate. By setting the interceptor plate 39, the operator first manually moves the interceptor plate 39 so that the interceptor plate 39 moves left and right along the inside of the storage frame 34. When the two interceptor plates 39 move to a position where the distance between them matches the size of the common rail valve plate, the two positioning rods 38 are manually inserted into the perforated plate 37 and the two interceptor plates 39 respectively to fix the two interceptor plates 39. This allows the two interceptor plates 39 to limit the common rail valve plate placed inside the storage frame 34, reducing the possibility of the common rail valve plate sliding or tipping over during the pushing process, which could cause collision and wear between the common rail valve plates or with the inner wall of the storage frame 34.

[0035] Figure 2 The inner wall of the storage frame 34 shown is fixedly connected with a directional rod 310, which is placed inside the two intercepting plates 39. By setting the directional rod 310, it can be placed inside the two intercepting plates 39 to limit their movement, reducing the possibility of the two intercepting plates 39 tilting during use and affecting the limiting effect on the common rail valve plate. A spring shaft 311 is fixedly connected to one side of each of the two intercepting plates 39. The spring shaft 311 has two return springs, and two auxiliary plates 312 are slidably connected to the surface of the spring shaft 311. The two auxiliary plates 312 are fixedly connected to the two return springs respectively. By setting the auxiliary plates 312, under the reaction force of the return springs, the two return springs on the spring shaft 311 push the two auxiliary plates 312 to move closer to each other. When the two auxiliary plates 312 move closer to the position where they are in contact with the surface of the common rail valve plate, the two auxiliary plates 312 assist in intercepting the common rail valve plate in the other two directions, further improving the limiting effect on the common rail valve plate.

[0036] Figure 5The system also includes a support assembly 4, which comprises: a perforated plate 41 fixedly attached to the concave plate 31 on the side away from the storage frame 34; and an L-shaped rod 43 slidably mounted on the perforated plate 41 via a spring rod 42, wherein the other end of the spring rod 42 is fixedly attached to the perforated plate 41, and the short arm end of the L-shaped rod 43 is in contact with the surface of the storage frame 34. By setting the support assembly 4, when the storage frame 34 moves out of the furnace body 1, the storage frame 34 pushes the L-shaped rod 43 to move away from the interior of the furnace body 1, causing the L-shaped rod 43 to pull the spring rod 42 along the interior of the perforated plate 41, so that the L-shaped rod 43 moves with the storage frame 34 and lifts the bottom of the storage frame 34 during the movement, thereby achieving support and reinforcement of the storage frame 34, reducing the possibility of the storage frame 34 falling off the side away from the perforated plate after it moves out of the furnace body 1, and improving the stability of the storage frame 34.

[0037] Figure 5 The L-shaped rod 43 shown is fixedly connected to a support plate 44 on its inner side. The surface of the support plate 44 is trapezoidal. By setting the support plate 44, the inner side of the L-shaped rod 43 can be supported and reinforced, reducing the swaying or tilting of the L-shaped rod 43 during use.

[0038] Working principle: First, the operator manually moves the interceptor plate 39, causing it to move left and right along the inside of the storage frame 34. When the distance between the two interceptor plates 39 matches the size of the common rail valve plate, the operator manually inserts the two positioning rods 38 into the perforated plate 37 and the two interceptor plates 39 respectively to fix the two interceptor plates 39. This limits the common rail valve plate placed inside the storage frame 34. Simultaneously, under the reaction force of the return spring, the two return springs on the spring shaft 311 push the two auxiliary plates 312 to move closer together. When the two auxiliary plates 312 move closer together to the position where they are in contact with the surface of the common rail valve plate, the... Two auxiliary plates 312 are used to assist in intercepting the common rail valve plate on the other two sides, thereby achieving auxiliary positioning of the common rail valve plate placed inside the storage frame 34. At this time, the storage frame 34 is manually moved to drive the pin 35 to move. When the storage frame 34 moves to the position where the pin 35 is inserted into the hole block 32, the storage frame 34 is placed inside the concave plate 31 and fixed with the hole block 32. At this time, the common rail valve plate is placed inside the storage frame 34 and the pull rod 33 is manually pushed to drive the hole block 32 and the storage frame 34 to move. When the storage frame 34 moves to the position where it is completely inside the concave plate 31, the storage frame 34 brings the common rail valve plate into the furnace body 1, completing the feeding of the common rail valve plate.

[0039] At this time, the CrN coating material is evaporated by resistance heating inside the furnace body 1, which transforms the solid material into gaseous atoms or molecules. The vaporized particles migrate in a vacuum environment and collide with inert gases such as argon to generate plasma. Some particles are ionized and then deposited on the surface of the common rail valve plate under the drive of electric field or thermal energy to form a dense film, thereby achieving the deposition process of CrN coating on the common rail valve plate. After the common rail valve plate is processed, the pull rod 33 is pulled again to pull the storage frame 34 out of the furnace body 1 and separate the storage frame 34 from the hole block 32, so that the storage frame 34 carries the processed common rail valve plate out of the furnace body 1 together, thereby achieving rapid material removal of the common rail valve plate.

[0040] When the storage frame 34 moves outward from the furnace body 1, it pushes the L-shaped rod 43 away from the interior of the furnace body 1. This causes the L-shaped rod 43 to pull the spring rod 42 along the inside of the circular hole plate 41, so that the L-shaped rod 43 moves with the storage frame 34 and lifts the bottom of the storage frame 34 during the movement, thereby supporting and reinforcing the storage frame 34.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
