Description

Technical Field

[0001] The utility model belongs to the technical field of main rib plate welding, in particular to a main rib plate assembly welding spring top positioning tool. Background Art

[0002] In the machinery manufacturing industry, we often encounter some assembly and welding workpieces, which need to be welded and then processed with holes, such as the main reinforcement plates of hydraulic support top beams, bases, etc. The main reinforcement plates are welded and attached to form main reinforcement plate assemblies.

[0003] Since there are multiple groups of holes on the main rib plate, the thickness of the welded plates at different holes of the same main rib plate is different or there is no plate at some holes. Therefore, fewer main rib plates can be clamped on the boring machine at one time, which increases the processing volume of the boring machine and makes it difficult to clamp and fix.

[0004] In addition, after the main rib plate assembly is bored, a process mandrel is used in the subsequent welding process of the top beam, base and other components, that is, the main rib plate assembly is put onto the process mandrel for welding.

[0005] However, during the operation, the core shaft is not easy to penetrate due to the large thickness of the main rib plate assembly (the main rib plate assembly is the main rib plate plus the veneer plate).

[0006] After the main rib plate assembly is put onto the mandrel by various means, in order to ensure the coaxiality of the holes of the assembled parts, the gap between the outer circle of the mandrel and the main rib plate holes is small. After welding construction, the assembly welding points are solid, and the process mandrel is more difficult to pull out, resulting in not only extremely cumbersome work operations but also extremely low work efficiency.

[0007] The main reasons for the above technical defects are: during the welding process, the main rib plate assembly needs to be matched with the core shaft. After installation, the main rib plate assembly needs to be kept in position, and there are certain requirements for the stability of the positioning, which makes it difficult to install the core shaft. Utility Model Content

[0008] Based on the above background, the purpose of the utility model is to provide a main rib plate assembly welding spring top positioning tool.

[0009] In order to achieve the above objectives, the utility model adopts the following technical solutions:

[0010] A main rib plate assembly welding spring-top positioning tool, comprising a mandrel mounted on the main rib plate assembly, wherein a plurality of spring-top mechanisms are assembled and connected to the mandrel;

[0011] The ejection mechanism includes a supporting ejection ball, the supporting ejection ball is limited in the shell structure, and the supporting top end of the supporting ejection ball is located outside the shell structure and is supported on the main rib plate assembly;

[0012] The housing structure is mounted on the mandrel;

[0013] The ejection mechanism also includes an elastic structure for elastically supporting the ejection ball;

[0014] When the main rib plate assembly is mounted on the core shaft, the supporting top ball is elastically expanded and contracted through the elastic structure to complete the mounting of the main rib plate assembly. After mounting, the supporting top ball elastically contacts the main rib plate assembly.

[0015] Preferably, the shell structure comprises a limiting cylinder for limiting the support of the top ball, the outer end of the limiting cylinder is the limiting end, and the supporting top ball is blocked on the inner side of the limiting end.

[0016] Preferably, the elastic structure includes a pad fixedly connected to the bottom position of the supporting top ball;

[0017] The cushion block is slidably connected in the limiting cylinder;

[0018] The elastic structure also includes a first spring fixedly connected to the bottom position of the cushion block, the bottom of the first spring is fixedly connected to a blocking seat that blocks the inner end of the limiting cylinder, and the first spring is fixedly connected to the blocking seat.

[0019] Preferably, the blocking seat is threadedly connected to the limiting cylinder.

[0020] Preferably, the elastic structure comprises a short limiting cylinder, the supporting top ball is limited in the short limiting cylinder, the outer end of the short limiting cylinder is the limiting end, and the supporting top ball is blocked on the inner side of the short limiting end;

[0021] The elastic structure also includes a push rod fixedly connected to the bottom position of the supporting push ball, and the push rod is slidably connected to the short limit cylinder;

[0022] The bottom of the push rod is fixedly connected with a spring seat, the spring seat is slidably connected in the core shaft, and the bottom of the spring seat is fixedly connected with a second spring;

[0023] The second spring is fixedly connected in the core shaft.

[0024] Preferably, a mounting recess for the second spring is formed at the bottom of the spring seat, the top of the second spring is fixed on the mounting recess, and the bottom of the spring is fixed in the cavity in the core shaft.

[0025] Preferably, the main rib plate assembly comprises a main rib plate and a plate welded to the main rib plate;

[0026] The central parts of the main rib plate and the pasting plate are both provided with a central hole, and the spring-pushing mechanism is elastically supported on the hole wall of the central hole.

[0027] Preferably, the left and right ends of the core shaft are respectively equipped with a spring-loaded mechanism.

[0028] The utility model has the following beneficial effects:

[0029] 1. The spring-pushing mechanism includes a supporting top ball, which is limited in the shell structure, and the supporting top end of the supporting top ball is located outside the shell structure and supported on the main rib plate assembly; the shell structure is installed on the core shaft; the spring-pushing mechanism also includes an elastic structure for elastically supporting the supporting top ball. During the installation process, when the main rib plate assembly is fitted onto the core shaft, the supporting top ball is elastically expanded and contracted by the elastic structure, and the main rib plate assembly is completed. After fitting, the supporting top ball elastically contacts the main rib plate assembly.

[0030] In the above method, during the assembly process, the support top ball can be elastically expanded and contracted, so that the center hole on the main rib plate assembly can be easily assembled onto the core shaft. After assembly, the support top ball elastically contacts the side wall of the center hole to position the main rib plate assembly. After welding, the support top ball can be elastically expanded and contracted, so that the material can be easily withdrawn. The above method not only greatly reduces the construction difficulty, which is reflected in the extremely rapid and convenient loading and unloading of materials, but also during the welding process, due to the contact of the support top ball, the main rib plate assembly is in an effective positioning state, thereby improving the stability of welding. Therefore, the above method greatly increases the welding construction efficiency.

Specifically, one structural mode is: a limiting cylinder, a pad supporting the bottom position of the ejector ball, a first spring at the bottom position of the pad, and a blocking seat. The ejector ball is supported through the pad and the first spring and can be elastically extended and retracted to facilitate feeding and withdrawing of materials, as well as positioning of the workpiece.

[0043] Example 1

[0044] like Figure 1-5 As shown, a main rib plate assembly welding spring-top positioning tool comprises a core shaft 4 which is mounted on the main rib plate assembly, and a plurality of spring-top mechanisms 3 are assembled and connected to the core shaft 4.

[0045] Specifically, the left and right ends of the core shaft 4 are respectively equipped with a spring-pushing mechanism 3, through which two sets of main rib plate assemblies can be simultaneously installed (the main rib plate assembly includes a main rib plate 1 and a plate 1 welded on the main rib plate 1; the main rib plate 1 and the plate 2 are both provided with a center hole in their central parts, and the spring-pushing mechanism 3 is elastically supported on the hole wall of the center hole).

[0046] The specific structure of the ejection mechanism 3 is as follows:

[0047] The pop-up mechanism 3 includes a supporting top ball 31, which is limited in the shell structure. The top end of the supporting top ball 31 is located outside the shell structure and is supported on the main rib plate assembly; the shell structure is installed on the core shaft 4; the pop-up mechanism 3 also includes an elastic structure for elastically supporting the supporting top ball 31.

[0048] During the installation process, when the main rib plate assembly is fitted onto the core shaft 4, the supporting top ball 31 is elastically expanded and contracted through the elastic structure to complete the fitting of the main rib plate assembly. After fitting, the supporting top ball 31 elastically contacts the main rib plate assembly.

[0049] During the assembly process achieved by the above method, the support top ball 31 elastically expands and contracts, thereby facilitating the assembly of the center hole on the main rib plate assembly onto the core shaft 4. After assembly, the support top ball 31 elastically contacts the side wall of the center hole to position the main rib plate assembly. After welding, the support top ball 31 can elastically expand and contract, thereby facilitating the removal of the material.

[0050] The above method not only greatly reduces the construction difficulty, but also makes loading and unloading of materials extremely quick and convenient. In addition, during the welding process, due to the resistance of the supporting top ball 31, the main rib plate assembly is in an effective positioning state, thereby improving the stability of welding. Therefore, the above method greatly increases the welding construction efficiency.

[0051] Example 2

[0052] like Figure 1-5 As shown, this embodiment discloses a shell structure and a matching elastic structure based on the structure of embodiment 1.

[0053] Specifically, the housing structure includes a limiting cylinder 34 (the limiting cylinder 34 is installed on the core shaft 4) for limiting the support top ball 31, the outer end of the limiting cylinder 34 is the limiting end (the limiting end is the edge of the limiting cylinder 34 protruding inward to form a limit), and the inner end of the supporting top ball 31 is blocked on the inner side of the limiting end. At the same time, the elastic structure includes a cushion block 32 fixedly connected to the bottom position of the supporting top ball 31; the cushion block 32 is slidably connected in the limiting cylinder 34.

[0054] The elastic structure also includes a first spring 33 fixedly connected to the bottom of the cushion block 32 (under the elastic action of the first spring 33, the supporting top ball 31 always maintains an elastic state), the bottom of the first spring 33 is fixedly connected to a blocking seat 35 that blocks the inner end of the limiting cylinder 34, and the first spring 33 is fixedly connected to the blocking seat 35. Specifically, the blocking seat is threadedly connected to the limiting cylinder 34.

[0055] During operation, when the main rib plate assembly is installed, the support top ball 31 is subjected to contact pressure. At this time, the first spring 33 is compressed, and the support top ball 31 retracts toward the limiting cylinder 34. Then, after installation, the support top ball 31 elastically contacts the center hole of the main rib plate assembly.

[0056] During actual work, in order to improve the elastic positioning effect, in the pop-up mechanism 3 of the above-mentioned structure, three ring-shaped array-distributed pop-up mechanisms 3 are distributed on the left and right sides of the core shaft 4, respectively, so as to achieve full elastic support against the main rib plate assembly from multiple positions, thereby increasing stability.

[0057] Example 3

[0058] like Figure 1-5 As shown, this embodiment discloses another shell structure and a matching elastic structure based on the structure of the embodiment 1.

[0059] Specifically, this elastic structure includes a short limit cylinder 36, and the support top ball 31 is limited in the short limit cylinder 36 (the support top ball 31 slides relative to the short limit cylinder 36, and the outer end of the support top ball 31 is located outside the short limit cylinder 36), and the short limit cylinder 36 is also installed on the core shaft 4), and the support top ball 31 is blocked on the inner side of the short limit end.

[0060] At the same time, the elastic structure also includes a top rod 361 fixedly connected to the bottom position of the supporting top ball 31, and the top rod 361 is slidably connected to the short limit cylinder 36. Correspondingly, the bottom of the top rod 361 is fixedly connected to a spring seat 37, and the spring seat 37 is slidably connected in the core shaft 4. The bottom of the spring seat 37 is fixedly connected to a second spring 38; the second spring 38 is fixedly connected in the core shaft 4.

[0061] Specifically, the second spring 38 is fixed in the following manner:

[0062] The bottom of the spring seat 37 is provided with a mounting recess for mounting the second spring 38. The top of the second spring 38 is fixed on the mounting recess, and the bottom of the second spring 38 is fixed in the mandrel 4, which is a hollow mandrel. Since the push rod 361 is slidably limited in the short limit cylinder 36, the spring seat 37-push rod 361 structure can perform linear telescopic motion relative to the short limit cylinder 36.

[0063] During the working process, when the main rib plate assembly is installed, the supporting top ball 31 is subjected to the contact pressure, and then retracts into the short limit cylinder 36, the top rod 361 and the spring seat 37 slide in the internal sliding cavity, and the second spring 38 is compressed. And, as the assembly is completed, at this time, under the elastic force of the second spring 38, the supporting top ball 31 on the top rod 361 is fully supported on the center hole of the main rib plate assembly, so that the main rib plate assembly can be easily assembled and the main rib plate assembly can be withdrawn, and the main rib plate assembly can be fully locked against the main rib plate assembly to ensure the stability of the processing.

[0064] In actual working process, two ejection mechanisms 3 of the above structure are respectively installed on both sides of the core shaft 4, so that two main rib plate assemblies are simultaneously installed on both sides of the core shaft 4. The ejection mechanisms 3 on each side are distributed at intervals of 180 degrees.

[0065] like Figure 5 As shown, at the same time, in order to facilitate the integrated extension and retraction of the two pop-up mechanisms 3 on each side, the second spring 38 connected to the two pop-up mechanisms 3 is specifically designed to be an integrated long spring, that is, the spring seats 37 on the pop-up mechanisms on both sides are connected integrally through a long spring. Therefore, during the working process, the spring seats 37 on both sides are synchronously extended and retracted through a whole spring.

[0066] Example 4

[0067] like Figure 1-5 As shown, based on the structure of Example 3, in order to improve the supporting stability of the ejection mechanism 3, the ejection mechanism 3 in Example 3 is improved as follows:

[0068] A pair of push rods 361 are fixed on the top of the spring seat 37, and a pair of matching short limit cylinders 36 are installed on the corresponding core shaft 4. During the lifting and lowering process of the spring seat 37, the pair of push rods 361 (the distribution direction of the two push rods 361 is: in the same direction as the axis of the core shaft 4) synchronously carry the two supporting top balls 31 and support them on the main rib plate workpiece, so as to simultaneously support the two supporting top balls 31 in the central empty position of the main rib plate workpiece, thereby greatly improving the support stability.

[0069] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the protection scope of the present invention.
