[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation, connection and connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0036] The utility model provides a shot blasting machine fixture for processing annular parts.
[0037] Before the detailed introduction, it is necessary to understand the application scenarios of the utility model: almost all steel castings, gray castings, malleable cast iron parts, ductile iron parts, etc. need to be shot blasted. This is not only to remove the oxide scale and sand sticking on the surface of the casting, but also an indispensable preparatory process before the quality inspection of the casting. For example, the casing of a large gas turbine must be strictly shot blasted before non-destructive testing to ensure the reliability of the testing results. In general casting production, shot blasting is an indispensable process for discovering surface defects of castings such as subcutaneous pores, slag holes, sand sticking, cold shut, peeling, etc. Further, shot blasting is a means of strengthening workpieces. Practice has proved that shot blasting is an effective process method for increasing the dislocation structure of metals. For some metals that cannot be hardened by phase transformation (such as martensitic quenching, etc.) or require further strengthening on the basis of phase transformation hardening, an important process measure is to use shot blasting technology to improve the strength and fatigue strength of the components.
[0038] In the traditional polishing machine processing, since most of the equipment is crawler-type flip processing, it cannot meet the processing requirements of parts with relatively high requirements. Especially for ring parts, uneven force often causes damage, affecting the polishing effect and processing accuracy. Based on this, a shot blasting machine fixture for processing ring parts is proposed.
[0039] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0040] like Figure 1-3 As shown, it is a schematic diagram of the overall structure of the utility model:
[0041] It should be clear that the fixed seat 1 is generally installed outside the working area of the shot blasting machine; the shaft tube 2, as the shaft of the entire fixture, passes through the fixed seat 1, and its part connected to the sleeve 3 penetrates into the working area of the shot blasting machine, and the other part is connected to the pulley 12. A threaded structure is provided inside the shaft tube 2; it is threadedly connected to one end of the screw 6. The other end of the screw 6 passes through the end cover 5 of the sleeve 3, and the sleeve 3 is sleeved outside the shaft tube 2. When the screw 6 is tightened, the end cover 5 and the sleeve 3 move toward the fixed seat 1; when the screw 6 is loosened, the end cover 5 and the sleeve 3 move in the opposite direction.
[0042] It should be clear that a plurality of connecting strips 4 are evenly arranged in an annular manner on the outer side of the sleeve 3 and are arranged axially along the shaft tube 2. The plurality here can be 3, 4 or more, as long as a 360-degree dispersed arrangement can be achieved around the sleeve. The connecting strips 4 and the support plates 7 are in one-to-one correspondence, and both are hinged to the connecting rod 8. Each group of corresponding connecting strips 4 and support plates 7 can be provided with one connecting rod 8, or two. If one is provided, the hinge point can be arranged in the center, which is more stable. If two are arranged, the hinge points are set at both ends of the connecting strip 4 and the support plate 7.
[0043] Furthermore, a slider 9 is provided at the top of the support plate 7, and the slider 9 slides in the limiting groove 11 of the limiting plate 10. The support plate 7 can only move radially but not axially relative to the limiting plate 10. Therefore, when the sleeve 3 moves toward the fixing seat 1 under the action of the screw 6, the support plate 7 is subjected to force under the action of the connecting rod 8, but because the support plate 7 cannot move axially, the support plate 7 moves radially relative to the limiting plate 10. That is, the support plate 7 is unfolded relative to the sleeve 3, and is sleeved in the annular workpiece and fixed.
[0044] Specifically, the screw 6 can be rotated manually or driven to rotate by the motor 14. The output shaft of the motor 14 cooperates with the top of the screw 6 to ensure the stability of power transmission. The specific model and specification of the motor 14 should be selected according to actual work requirements to ensure sufficient power output. When the motor 14 is started, its output power is transmitted to the screw 6, causing the screw 6 to rotate. The rotational movement of the screw 6 causes the support plate 7 to move accordingly, achieving the functions of tightening and relaxing. When tightening is required, the motor 14 is started, and the output power causes the screw 6 to rotate. The rotation of the screw 6 pushes the sleeve 3 toward the limit plate 10, and drives the support plate 7 to move outward through the connecting rod 8 until the support plate 7 is in close contact with the target object, thereby achieving a tightening effect. When relaxation is required, the motor 14 rotates in the opposite direction, causing the screw 6 to rotate in the opposite direction. The reverse rotation of the screw 6 drives the support plate 7 to move inward, thereby achieving a relaxing effect.
[0045] It should be noted that one end of the pulley 12 is connected to a power source, which is the motive force for the rotation of the entire fixture. The pulley 12 is coaxially connected to the rotating axis of the shaft tube 2 to achieve the rotation of the shaft tube 2. The general power source is an engine.
[0046] Furthermore, the support plate 7 is a flat plate with a certain thickness and strength, and its main function is to provide support. Ribs 13 are provided on the support plate 7, and the number and position of the ribs 13 can be adjusted according to actual needs. The ribs 13 are convex structures provided on the support plate 7, and their main function is to increase the rigidity and stability of the support plate 7.
[0047] Specifically, Figure 1 As shown, in the first embodiment, the main part of the limit plate 10 is a flat plate-shaped circular structure, and is coaxially arranged with the shaft tube 2. The structure is relatively stable during the rotation process. When in use, in order to further improve the energy-saving efficiency, the structure of the limit plate 10 can be optimized, that is, Figure 2 In the second embodiment shown, the limit plate 10 is composed of three branches, which point to three directions respectively and are distributed at an angle of 120 degrees. The three branches form a stable whole, and the Y-shaped limit plate 10 saves materials. The limit grooves 11 are provided in the three branches, and the corresponding functions can also be achieved. Similarly, a cross shape with four branches is also possible, which also has high stability and is not easy to deform.
[0048] Furthermore, the support plate 7 is a key component of the support, and the main body is made of high-strength metal material, which has high bearing capacity and stability. The surface of the support plate 7 in contact with the annular workpiece is arc-shaped, and its arc shape increases the contact area with the inner side of the annular workpiece. The arc-shaped contact surface can make the support plate 7 contact with the annular workpiece more uniformly, reduce local pressure, and improve the support effect.
[0049] Specifically, the flat part of the support plate 7 that contacts the annular workpiece is covered with a flexible anti-skid rubber layer (not shown in the figure). The rubber layer has good elasticity and wear resistance. On the one hand, it can form a tightly fitting protective layer on the surface of the annular workpiece, and on the other hand, it can effectively increase the friction between the support plate 7 and the annular workpiece to prevent the workpiece from sliding during processing.
[0050] It should be noted that the I-shaped design of the slider 9 gives it a high structural strength and stability, which is conducive to improving its reliability during movement. The clamping method of the slider 9 and the limit plate 10 makes the connection between the two more secure, reducing the risk of the slider 9 falling off due to factors such as vibration.
[0051] Furthermore, a gap is provided between the sleeve 3 and the shaft tube 2, and the gap is sufficient to accommodate the roller strip 15. The outer diameter of the sleeve 3 matches the inner diameter of the shaft tube 2 to ensure that the sleeve 3 can be tightly sleeved on the shaft tube 2. The two ends of the roller strip 15 are respectively fixed on the inner side of the sleeve 3 so that it extends along the axial direction of the sleeve 3. The material of the roller strip 15 can be selected from wear-resistant, high-hardness, and corrosion-resistant metal or non-metallic materials, such as stainless steel, carbon steel, nylon, etc., to adapt to different working environments and requirements. The provision of the roller strip 15 improves the sliding smoothness between the sleeve 3 and the shaft tube 2.
[0052] It should be noted that after the annular part is clamped, the part can be rotated for processing. The entire mechanism is driven to rotate by the pulley 12. The screw 6 and the sleeve 3 are threadedly connected, and the sleeve 3 always receives the thrust of the connecting rod 8, so it is always in a tight fit and will not loosen. It is ensured that the support plate 7 will not loosen during processing.
[0053] It should be noted that the above embodiment is only a specific implementation of the utility model and is not limited to the embodiment. For ordinary technicians in this field, various changes and modifications can be made without departing from the spirit and scope of the technical solution of the utility model, which should be included in the protection scope of the utility model.
[0054] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
