Description

Technical Field

[0001] The utility model relates to the technical field of aluminum valve body processing, in particular to a positioning device for aluminum valve body processing. Background Art

[0002] Aluminum valve body is an important part of automobile engine, used to control the intake and exhaust of automobile, and is one of the core parts of automobile valve mechanism. Aluminum valve body is made of aluminum alloy. Due to its advantages of light weight, corrosion resistance and good heat dissipation, it is widely used in automobile industry, especially in high-end models. At present, domestic and foreign automobile manufacturers generally use aluminum valve body to improve the performance and reliability of automobile engine and meet the requirements of environmental protection and energy saving.

[0003] Because the clamping surface of the conventional aluminum valve body processing positioning device is generally set up with a flat structure, but the valve body surface is usually an irregular curved surface or a special-shaped structural surface, this flat structure clamping surface is difficult to ensure the stability of the aluminum valve body positioning, which can easily lead to structural errors in the subsequent processing of the aluminum valve body, affecting the processing quality of the aluminum valve body.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a positioning device for aluminum valve body processing is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a positioning device for aluminum valve body processing to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning device for aluminum valve body processing, comprising an adjusting seat and an upper clamping rod, wherein positioning seats are installed at both ends of the middle part of the adjusting seat, and a lower clamping rod is installed on the side of the positioning seat close to the vertical central axis of the adjusting seat, and the upper end of the positioning seat is connected to a movable seat, and the upper clamping rod is installed on the side of the movable seat close to the vertical central axis of the adjusting seat, and the upper clamping rod comprises a supporting pile, a spring telescopic rod, a push rod and an anti-slip sleeve, a spring telescopic rod is installed inside the supporting pile, and the end of the spring telescopic rod away from the movable seat is connected to the push rod, and the surface of the end of the push rod away from the spring telescopic rod is covered with an anti-slip sleeve.

[0007] Furthermore, the adjustment seat includes a base, fixed piles, a bidirectional screw and auxiliary guide rails. Fixed piles are installed on both ends of the base, and a bidirectional screw is horizontally arranged between the left and right fixed piles, and auxiliary guide rails are horizontally arranged on both sides of the bidirectional screw.

[0008] Furthermore, the bidirectional lead screw and the auxiliary guide rail are parallel to each other, and the fixed pile and the bidirectional lead screw are connected in an "I"-shaped structure.

[0009] Furthermore, the positioning seat includes a moving seat, a lower clamping block and a screw pile. The top of the moving seat is connected to the lower clamping block, and the middle of the side of the lower clamping block away from the lower clamping rod is connected to the screw pile.

[0010] Furthermore, the positioning seat also includes a bidirectional screw rod and a guide frame. A bidirectional screw rod vertically penetrates the middle of the screw rod pile, and guide frames are arranged on the left and right sides of the screw rod pile.

[0011] Furthermore, the guide frame is fixedly connected to the lower clamping block, the bidirectional screws of the screw pile are threadedly connected, and the movable seat is threadedly connected and slidably connected to the bidirectional screw and the auxiliary guide rail respectively.

[0012] Furthermore, the movable seat includes an upper clamping block, a threaded pile and a guide groove. The middle part of the upper clamping block away from the upper clamping rod is connected with a threaded pile, and the left and right ends of the surface of the side of the upper clamping block away from the upper clamping rod are provided with guide grooves.

[0013] Furthermore, the lower clamping rod and the upper clamping rod have the same structure, and are respectively installed in an equidistant array on the lower clamping block and on one side of the lower clamping block close to the vertical central axis of the adjustment seat.

[0014] The utility model provides a positioning device for aluminum valve body processing, which has the following beneficial effects:

[0015] 1. The utility model installs a plurality of lower clamping rods and upper clamping rods in an array on the surface of the lower clamping block and the upper clamping block on one side close to the vertical central axis of the adjusting seat, and utilizes the structural elasticity of the spring telescopic rod so that the push rod in contact with the surface of the aluminum valve body can be appropriately telescopically adjusted according to its surface structure. By using this dot matrix structure, the aluminum valve body with a complex surface structure can be flexibly and stably clamped and positioned, ensuring that the aluminum valve body can be stably processed subsequently. The support piles can strengthen the structural strength of the joints between the spring telescopic rod and the lower clamping block and the upper clamping block, and the anti-slip sleeve covered on the surface of the push rod can ensure the friction between the push rod and the surface of the aluminum valve body to ensure the stability of clamping, and can also minimize the rigid contact between the push rod and the surface of the aluminum valve body to cause structural wear, thereby affecting the processing quality of the aluminum valve body.

[0016] 2. The utility model, by horizontally screwing the bidirectional lead screw, allows the movable seat threadedly connected to its surface to simultaneously perform horizontal displacement along the surfaces of the bidirectional lead screw and the auxiliary guide rail, thereby driving the positioning seat and the movable seat, as well as the lower clamping rod and the upper clamping rod installed on one side thereof, to achieve the left and right positioning and clamping of the aluminum valve body, and by vertically screwing the bidirectional lead screw, the relative distance between the positioning seat and the movable seat connected thereto can be adjusted in the vertical direction, thereby further providing vertical positioning and clamping of the aluminum valve body up and down, and by using the combined use of the above structures, the aluminum valve body can be positioned and clamped in any manner within the adjustable range to the greatest extent, which not only ensures the structural flexibility of the use of the entire device, but also provides flexible structural assistance for the processing of the aluminum valve body, thereby meeting different processing needs as much as possible.

[0022] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0023] like Figures 1 to 4As shown, a positioning device for aluminum valve body processing includes an adjusting seat 1 and an upper clamping rod 5, a positioning seat 2 is installed at both ends of the middle part of the adjusting seat 1, and a lower clamping rod 3 is installed on the side of the positioning seat 2 close to the vertical central axis of the adjusting seat 1, and the upper end of the positioning seat 2 is connected to a movable seat 4, the upper clamping rod 5 is installed on the side of the movable seat 4 close to the vertical central axis of the adjusting seat 1, the upper clamping rod 5 includes a supporting pile 501, a spring telescopic rod 502, a push rod 503 and an anti-slip sleeve 504, the spring telescopic rod 502 is installed inside the supporting pile 501, and the end of the spring telescopic rod 502 away from the movable seat 4 is connected to the push rod 503, and the surface of the end of the push rod 503 away from the spring telescopic rod 502 is covered with an anti-slip sleeve 504, the movable seat 4 includes an upper clamping block 401, a screw The threaded pile 402 and the guide groove 403, the middle part of the side of the upper clamping block 401 away from the upper clamping rod 5 is connected with the threaded pile 402, and the left and right ends of the surface of the side of the upper clamping block 401 away from the upper clamping rod 5 are provided with guide grooves 403, the lower clamping rod 3 and the upper clamping rod 5 have the same structure, and the lower clamping rod 3 and the upper clamping rod 5 are respectively installed in an equidistant array on the lower clamping block 202 and the side of the lower clamping block 202 close to the vertical central axis of the adjustment seat 1, and the structural elasticity of the spring telescopic rod 502 is utilized, so that the top rod 503 in contact with the surface of the aluminum valve body can be appropriately telescopically adjusted according to its surface structure, and the use of this dot matrix structure can realize flexible and stable clamping and positioning of the aluminum valve body with a complex surface structure, ensuring that the aluminum valve body can be stably processed in subsequent processing.

[0024] like Figures 1 to 4As shown, the adjusting seat 1 includes a base 101, a fixed pile 102, a bidirectional lead screw 103 and an auxiliary guide rail 104, the left and right ends of the base 101 are installed with fixed piles 102, and a bidirectional lead screw 103 is horizontally arranged between the left and right fixed piles 102, and auxiliary guide rails 104 are horizontally arranged on both sides of the bidirectional lead screw 103, the bidirectional lead screw 103 and the auxiliary guide rails 104 are parallel to each other, and the fixed pile 102 and the bidirectional lead screw 103 are connected in an "I"-shaped structure, the positioning seat 2 includes a moving seat 201, a lower clamping block 202 and a lead screw pile 203, the top of the moving seat 201 is connected to the lower clamping block 202, and the middle part of the lower clamping block 202 away from the lower clamping rod 3 is connected to the lead screw pile 203, the positioning seat 2 also includes a bidirectional lead screw 204 and a guide frame 205, the middle part of the lead screw pile 203 is vertically penetrated by the bidirectional lead screw 204, and the lead screw pile 20 Guide frames 205 are arranged on the left and right sides of 3, and the guide frames 205 are fixedly connected to the lower clamping block 202, and the screw piles 203 and the bidirectional screw rods 204 are threadedly connected. The movable seat 201 is threadedly connected and slidably connected to the bidirectional screw 103 and the auxiliary guide rail 104 respectively. By horizontally screwing the bidirectional screw 103, the movable seat 201 threadedly connected to its surface can be horizontally displaced along the surfaces of the bidirectional screw 103 and the auxiliary guide rail 104 at the same time, thereby driving the positioning seat 2 and the movable seat 4, as well as the lower clamping rod 3 and the upper clamping rod 5 installed on one side thereof, to realize the left and right positioning and clamping of the aluminum valve body, and by screwing the bidirectional screw rod 204 in the vertical direction, the relative distance between the positioning seat 2 and the movable seat 4 connected thereto can be adjusted in the vertical direction, thereby further providing the vertical positioning and clamping of the aluminum valve body.

[0025] In summary, if Figures 1 to 4 As shown, when using the positioning device for aluminum valve body processing, first place the aluminum valve body to be positioned and clamped in the middle of the entire device, and then screw the bidirectional lead screw 103 horizontally erected in the middle of the base 101 by the fixed pile 102 in the horizontal direction. At this time, the positioning seat 2 connected with the bidirectional lead screw 103 structure by the movable seat 201 will move toward the side surface of the aluminum valve body in the middle at the left and right ends of the adjustment seat 1, and at the same time drive the lower clamping rod 3, the movable seat 4 and the upper clamping rod 5 connected thereto to synchronously move until the lower clamping rod 3 and the upper clamping rod 5 are completely in structural contact with the aluminum valve body;

[0026] As the adjustment seat 1 is adjusted, the lower clamping rod 3 and the upper clamping rod 5 will gradually press against the surface of the aluminum valve body. At this time, the top rods 503 with the anti-slip sleeves 504 on the surface will exert a structural compression force on the spring telescopic rod 502 connected thereto due to the different surface structures of the aluminum valve body, so that the lower clamping rod 3 and the upper clamping rod 5 arranged in the array are adapted to the surface structure of the aluminum valve body.

[0027] Then, the bidirectional screw rod 204 in the screw rod pile 203 is vertically screwed in the vertical direction. As the bidirectional screw rod 204 rotates vertically axially, the upper clamping block 401 will use the threaded pile 402 to translate along the surface of the bidirectional screw rod 204. While the upper clamping block 401 moves along the surface of the bidirectional screw rod 204, the sliding connection between the side surface guide groove 403 and the guide frame 205 is used to smoothly control the movement. As the vertical relative distance between the movable seat 4 and the positioning seat 2 is adjusted, the aluminum valve body is further positioned and clamped to ensure the stability of its structure.
