Description

Technical Field

[0001] This utility model relates to the field of spring clip processing technology, and in particular to an automated shot blasting loading fixture for spring clip workpieces. Background Technology

[0002] High-speed railway elastic clips are track components that fix two rails together. They are extremely critical track components that ensure the safe and normal operation of high-speed trains. Therefore, the performance requirements for elastic clip fasteners are very high, especially their fatigue performance.

[0003] When the spring clip is in working condition, it is subjected to torsional stress, and the surface of the spring clip is the part subjected to the greatest torsional stress. Therefore, any defects on the surface of the spring clip will affect the fatigue life of the fastener. After a lot of tests, if there is rust defect on the surface of the spring clip, it will greatly reduce the fatigue life of the spring clip, and most of them will experience fatigue fracture in a very short time.

[0004] Currently, spring clips need to undergo surface shot blasting. Shot blasting removes impurities such as oxide scale and rust from the surface of the spring clips through high-speed shot impact, ensuring the accuracy of subsequent processing and the adhesion of the paint film. However, the existing processing method is to directly pour several spring clips into the shot blasting equipment for loading and shot blasting. This method is inconvenient for unloading the spring clips, and other equipment is needed to sort and unload the shot-blasted spring clips, which is very inconvenient and reduces work efficiency. Therefore, it is necessary to design an automated shot blasting loading fixture for spring clip workpieces. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, which involves directly pouring several spring bars into the shot blasting equipment for loading and shot blasting, making it inconvenient to pick up the spring bars and requiring other equipment to sort and pick up the finished spring bars, thus reducing work efficiency, one of the purposes of this utility model is to provide an automated shot blasting loading fixture for spring bar workpieces.

[0006] One of the objectives of this utility model is achieved by the following technical solution: an automated shot blasting loading fixture for elastic workpieces, comprising a support frame: slots are equidistantly provided on the support frame, and a fixture structure is attached to the inner wall of the slots. The fixture structure includes a horizontal bar, vertical bars equidistantly fixed on the horizontal bar, and connectors installed at both ends of the horizontal bar. The connectors are attached to the inner wall of the slots, and the elastic workpiece body is hung on the fixture structure.

[0007] According to the aforementioned automated shot blasting and loading fixture for elastic workpieces, the end face cross-section of the connecting member is hexagonal.

[0008] According to the aforementioned automated shot blasting loading fixture for elastic workpieces, the number of elastic workpiece bodies is several, and the several elastic workpiece bodies are hung between the vertical rods.

[0009] According to the aforementioned automated shot blasting loading fixture for elastic workpieces, slots are provided at both ends of the crossbar near the connecting member, and the connecting member is inserted into the inner wall of the slot.

[0010] According to the aforementioned automated shot blasting loading fixture for elastic workpieces, the upper and lower surfaces of the bracket are both screwed with horizontal plates, and a lifting lug is fixed in the middle of the horizontal plate.

[0011] According to the aforementioned automated shot blasting and loading fixture for elastic workpieces, the height of the vertical rod is higher than the height of the topmost point of the elastic workpiece body.

[0012] The above-mentioned solution has the following beneficial effects:

[0013] 1. By setting up a bracket, slot, and hanger structure, compared to directly pouring several spring clip workpieces into the shot blasting equipment for shot blasting, the hanger structure and bracket facilitate the picking and loading of spring clip workpieces, effectively improving work efficiency. It eliminates the need to use a transmission device to sort and transport the spring clip workpieces, thereby saving operating costs and effectively improving the practicality of the device.

[0014] 2. By setting up lifting lugs, connectors, and hanger structures, multiple hanger structures can be assembled together using connectors according to actual needs, thereby increasing the number of spring workpiece bodies and thus improving shot blasting efficiency. The hanger fixtures can be transferred using external robotic arms or hoisting equipment, making it easier to transfer the spring workpiece bodies to the shot blasting equipment for processing, effectively increasing the applicability of the device and improving its convenience.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figures 1-5 An automated shot blasting loading fixture for elastic workpieces includes a support 1. The support 1 has slots 2 evenly spaced on it. A fixture structure 3 is attached to the inner wall of the slots 2. The fixture structure 3 includes a horizontal bar 31, vertical bars 32 evenly fixed on the horizontal bar 31, and connectors 33 installed at both ends of the horizontal bar 31. The connectors 33 are attached to the inner wall of the slots 2. An elastic workpiece body 4 is hung on the fixture structure 3. The end face of the connector 33 has a hexagonal cross section. There are several elastic workpiece bodies 4. Several elastic workpiece bodies 4 are hung between the vertical bars 32. Slots 5 are opened at both ends of the horizontal bar 31 near the connectors 33. The connectors 33 are inserted into the inner wall of the slots 5. Horizontal plates 6 are screwed to the upper and lower surfaces of the support 1. A lifting lug 7 is fixed in the middle of the horizontal plate 6. The height of the vertical bar 32 is higher than the height of the top of the elastic workpiece body 4.

[0026] The length of the horizontal bar 31 and the number of vertical bars 32 in the hanging structure 3 are not specifically required. The height of the bracket 1 and the number of slots 2 are not specifically required. The length of the horizontal plate 6 is not specifically required and can be designed according to actual needs. The height of the vertical bar 32 is higher than the height of the elastic workpiece body 4, which can prevent the elastic workpiece body 4 from falling off the horizontal bar 31. The vertical bar 32 plays the role of limiting and separating several elastic workpiece bodies 4, preventing them from colliding with each other and becoming skewed. Compared with the method of directly pouring several elastic workpiece bodies 4 into the shot blasting equipment for shot blasting, by setting the hanging structure 3 and the bracket 1, it is easier to pick up and load the elastic workpiece bodies 4, which effectively improves the work efficiency. It is not necessary to use the transmission equipment to sort and transport the elastic workpiece bodies 4, thereby saving the operating cost and effectively improving the practicality of the device.

[0027] Working principle: The bracket 1 and two horizontal plates 6 are assembled together with screws to form a hanging fixture. The connector 33 is assembled with the horizontal bar 31. One end of the connector 33 is inserted into the slot 5 opened in the horizontal bar 31, thus assembling the connector 33 with the horizontal bar 31. An external robot arm is used to hang several elastic clip workpiece bodies 4 on the horizontal bar 31, so that the elastic clip workpiece bodies 4 are located between the vertical bars 32, thereby separating the several elastic clip workpiece bodies 4 and avoiding collisions and skewing between them, thus avoiding uneven shot blasting of the elastic clip workpiece bodies 4. Then, the robot arm or external clamping equipment is used to support the connector 33 at both ends of the horizontal bar 31. The connectors 33 at both ends overlap in the slot 2, thereby assembling several elastic clip workpiece bodies 4 onto the hanging fixture. Then, multiple elastic clip workpiece bodies 4 are hung on the hanging structure 3, and multiple hanging structures 3 are assembled on the hanging fixture. Then, the lifting lugs 7 are lifted by external hoisting equipment or a robot arm to transfer the hanging fixture to the shot blasting equipment, thereby realizing the shot blasting of multiple elastic clip workpiece bodies 4 at one time. Compared with the existing method of directly pouring the elastic clip workpiece bodies 4 into the shot blasting equipment for shot blasting, this device uses the hanging structure 3 and the hanging fixture to facilitate the loading and unloading of elastic clip workpiece bodies 4, effectively improving the practicality and convenience of the device.

[0028] When shot blasting requires adding a spring clip workpiece body 4 according to actual needs, two or more hanger structures 3 are assembled together. One end of the connector 33 assembled on one hanger structure 3 is inserted into the inner wall of the slot 5 opened on the crossbar 31 of another hanger structure 3, thereby assembling the two hanger structures 3 together, thus increasing the number of spring clip workpiece bodies 4. Then, the distance between the two supports 1 is adjusted according to the length of the two hanger structures 3 after assembly. A crossbar 6 of appropriate length is selected and installed on the two supports 1 to form a hanger fixture. After that, the assembled hanger structure 3 is assembled onto the hanger fixture, thereby meeting different usage requirements and effectively improving the applicability of the device.

[0029] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
