Description

A groove positioning device for plate body flame cutting TECHNICAL FIELD

[0001] The present application relates to the technical field of hydraulic support parts processing, in particular to a groove positioning device for plate body flame cutting. BACKGROUND

[0002] With the continuous improvement of plate body cutting quality, the groove cutting of the plate body (movable part) is carried out by a cutting machine. The cutting machine is provided with a workbench. The plate body is hoisted in parallel to the positioning area on the workbench, and the cutting machine will automatically cut after programming. The cutting machine is relatively large in size and is generally used for cutting and processing of large plate bodies. Although it can also cut small plate bodies, the transportation of small plate bodies is not convenient for the cutting machine, and the transportation cost is relatively high. In addition, the top end of the workbench is provided with a plurality of spaced apart heat dissipation plates, and the heat dissipation plates are provided with heat dissipation grooves. Sometimes the size of the small plate body does not match the size of the heat dissipation plate or the heat dissipation groove. In order to ensure the economic benefit of the cutting machine, a positioning device is usually used to assist the cutting torch in groove cutting processing of small plate bodies.

[0003] Most of the existing positioning devices are base plates. The plate body is hoisted in parallel on the base plate, and the plate body is positioned before cutting with a cutting torch. The whole process can be completed independently by manual operation, and the flexibility is relatively strong. However, in the plate body blanking process (pre-process), that is, in the cutting process of the profile of the plate body, the profile of the plate body will deform when heated. If the plate body is directly placed in parallel on the base plate, the position deviation between the theoretical placement position and the actual placement position of the plate body is large, thereby affecting the cutting quality of the groove. In addition, the parallel placement method makes the contact area between the plate body and the base plate larger, and the plate body is easy to deform again due to delayed heat dissipation when cutting the groove, which will cause thermal expansion and contraction, resulting in reduced cutting precision of the groove.

[0004] Therefore, there is an urgent need for a groove positioning device for plate body flame cutting.

[0053] In the present application, unless otherwise explicitly specified and limited, the terms "connection", "fixing" and the like should be understood broadly, for example, "fixing" can be fixed connection, or detachable connection, or integral; "connection" can be mechanical connection, or electrical connection; can be directly connected, or indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements, unless otherwise explicitly limited. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0054] Referring to FIGS. 1-3, the present application provides a groove positioning device for plate body flame cutting, which comprises a base plate 1, a baffle 2 and a pair of clamping plate mechanisms 3 vertically arranged on the base plate 1; the baffle 2 and the pair of clamping plate mechanisms 3 are arranged in transverse parallel; the clamping plate mechanism 3 is transversely slidably connected with the base plate 1; the top end of the clamping plate mechanism 3 is longitudinally arrayed with a plurality of clamping strips 4; a clamping groove 41 is formed between adjacent clamping strips 4; the clamping plate mechanism 3 can drive the plurality of clamping strips 4 to move longitudinally.

[0055] A plate body can be placed in a clamping groove 41, and the plate body is longitudinally limited by a pair of adjacent clamping strips 4. Compared with the traditional way of placing the plate body on the base plate, the groove positioning device for plate body flame cutting can vertically place the plate body, and after vertical placement, the cutting surface of the plate body is located at the top end of the plate body, and the cutting torch can complete the groove cutting of a plate body at one time, which not only ensures the cutting efficiency, but also exposes the cutting surface of the plate body to the air, ensuring efficient heat dissipation of the plate body during cutting, thereby effectively improving the plate body groove cutting precision, efficiency and yield.

[0056] The transversely slidably connection of the clamping plate mechanism 3 with the base plate 1 makes the spacing of the pair of clamping plate mechanisms 3 adjustable, improving the processing adaptability of the groove positioning device for plate body flame cutting to plate bodies of different lengths. The baffle 2 serves as a base plate, and one end of each of a plurality of plate bodies abuts against the baffle 2, effectively improving the placement efficiency and cutting efficiency of the plurality of plate bodies. In the present embodiment, as shown in FIG. 1, the baffle 2 is arranged on the left side of the pair of clamping plate mechanisms 3, and the side of the baffle 2 facing the pair of clamping plate mechanisms 3 is the reference surface.

[0057] The clamping plate mechanism 3 can drive the plurality of clamping strips 4 to move longitudinally, and a pair of clamping plate mechanisms 3 can drive the corresponding clamping strips 4 to move in opposite directions to clamp the plurality of plate bodies, so that the end surface of the plate body is perpendicular to the top surface of the base plate 1, the placement position error of the plate body on the pair of clamping plate mechanisms 3 is reduced, and the groove cutting precision is improved; meanwhile, the machining adaptability of the groove positioning device for plate body flame cutting to plate bodies of different thicknesses is also improved.

[0058] As shown in FIG. 4, in actual operation, the distance between the pair of clamping plate mechanisms 3 is adjusted according to the length of the workpiece 7 to be machined, and then the plurality of workpieces 7 are placed vertically on the pair of clamping plate mechanisms 3 one by one, and the plurality of workpieces 7 are in abutment with the baffle 2. Since the force of the workpiece 7 on the pair of clamping plate mechanisms 3 is mainly concentrated in the longitudinal and vertical directions, the lateral movement of the pair of clamping plate mechanisms 3 can be limited by friction braking, which is simple in structure and convenient to operate. After the plurality of workpieces 7 are installed, the clamping plate mechanism 3 drives the plurality of clamping strips 4 to move longitudinally, thereby driving the workpiece 7 to move longitudinally, and the pair of clamping plate mechanisms 3 moves in the opposite direction, so that the plurality of workpieces 7 are clamped, the placement position precision of the plate body is fine-tuned, the placement position precision of the plate body of the groove positioning device for plate body flame cutting is improved, and the cutting precision of the plate body groove is further improved.

[0059] In the first embodiment, as shown in FIGS. 5 and 6, the clamping plate mechanism 3 includes a connecting plate 31, a sliding plate 32, and a sliding module 33; the top end of the connecting plate 31 is connected with the plurality of clamping strips 4; the bottom end of the sliding plate 32 is slidingly connected with the base plate 1; the sliding plate 32 and the connecting plate 31 are connected through the sliding module 33, and the sliding module 33 can drive the connecting plate 31 to move longitudinally. Optionally, the connecting plate 31 and the plurality of clamping strips 4 are integrally cut and formed to ensure the precision of the clamping groove 41, thereby improving the positioning precision of the plate body. The sliding module 33 can be a lead screw and sliding block module or a linear motor module, as long as it can linearly push and pull the sliding plate 32. In this embodiment, a lead screw and sliding block module is selected to enable manual adjustment. The lead screw and sliding block module is a conventional lead screw and sliding block motor structure, which drives the sliding plate connected with the lead screw threads to move by rotating the lead screw, thereby driving the sliding plate 32 connected with the sliding plate to move synchronously. The lead screw and sliding block module has self-locking force, which can ensure the longitudinal positioning strength of the plate body and is simple and efficient in adjustment.

[0060] In the second embodiment, referring to FIG. 7, the clamping plate mechanism 3 comprises a connecting plate 31 and an adjusting bolt 34; the bottom end of the connecting plate 31 is in sliding connection with the bottom plate 1, and the top end is connected with a plurality of clamping strips 4; the clamping strip 4 is in threaded connection with the adjusting bolt 34; the adjusting bolt 34 can be moved into the clamping groove 41 along the longitudinal direction. Specifically, the adjusting bolt 34 is in threaded connection with the clamping strip 4, and the clamping strip 4 is equivalent to a top screw, which can adjust the longitudinal size of the clamping groove 41, thereby clamping the plate body in the clamping groove 41, and realizing the adjustment of the placement position precision of the plate body. In actual operation, a plurality of plate bodies are placed on a pair of clamping plates 3 one by one, and each time a plate body is placed, one adjusting bolt 34 is tightened to realize the adjustment of the placement position precision of the plate body.

[0061] The first embodiment and the second embodiment can be used alone or simultaneously, such as integrating the adjusting bolt 34 in the second embodiment into the clamping strip 4 in the first embodiment. Due to the manufacturing error and the deformation of the blank of the plurality of plate bodies, when the first embodiment adjusts the placement position precision of the plate body, there is a situation that one plate body has been clamped (the sliding plate 32 cannot be moved longitudinally) while the other plate bodies have not been clamped. In order to further improve the placement position precision of the plate body of the bevel positioning device for flame cutting of the plate body, the plate bodies that have not been clamped are compensated and adjusted by tightening the adjusting bolt 34, and finally the stable clamping and high-precision positioning of all the plate bodies are realized.

[0062] As shown in FIG. 8, the clamping strip 4 is coaxially provided with a limiting hole 42 and a threaded hole 43; the nut of the adjusting bolt 34 is arranged in the limiting hole 42, and the limiting hole 42 can limit the longitudinal movement of the nut of the adjusting bolt 34; and the screw rod of the adjusting bolt 34 is in threaded connection with the threaded hole 43. Specifically, the cross section of the limiting hole 42 and the threaded hole 43 is T-shaped, the adjusting bolt 34 is a T-shaped bolt with a nut, and the limiting hole 42 can effectively limit the maximum extension amount of the adjusting bolt 34 in the clamping groove 41, so as to avoid the situation that the adjusting bolt 34 is screwed out of the clamping strip 4 due to the visual blind area.

[0063] It should be noted that after the first embodiment completes the adjustment of the placement position precision of the plate body, the wrench cannot be tightened to the adjusting bolt 34 due to the interference with the plate body. One of the solutions is to place the plate bodies in the plurality of clamping grooves 41 at intervals, such as placing the plate bodies in the two clamping grooves 41 on the sides among the three clamping grooves 41, and leaving the middle clamping groove 41 empty, so as to facilitate the adjustment of the adjusting bolt 34 and realize the compensation adjustment of the plate body. The second solution is to tighten all the adjusting bolts 34 to the limit position, i.e. the position where the nut of the adjusting bolt 34 abuts against the threaded hole 43, and then adjust according to the adjustment mode of the first embodiment, which can effectively reduce the influence of the manufacturing error and the deformation of the blank of the plurality of plate bodies on the placement position precision, and realize the stable clamping and high-precision positioning of all the plate bodies.

[0064] Further, a pair of first sliding grooves 11 are formed on the bottom plate 1; the bottom end of the clamping plate mechanism 3 is provided with a pair of sliding blocks 35; the pair of sliding blocks 35 are correspondingly and slidably connected with the pair of first sliding grooves 11. Compared with the mode that the side plate is arranged on the bottom plate 1 and the first sliding groove 11 is formed on the side plate, the first sliding groove 11 is formed on the top surface of the bottom plate 1, which can effectively ensure sufficient heat dissipation during cutting of the plate body and reduce the thermal deformation of the plate body; and will not interfere with the adjustment of the sliding module 33 and the adjusting bolt 34.

[0065] In an embodiment, the bevel positioning device for plate body flame cutting further comprises a reinforcing rib 5, a fastening bolt 51 and a fastening nut 52; the side surface of the reinforcing rib 5 is connected with the clamping plate mechanism 3, and the bottom surface is in abutment with the bottom plate 1; the reinforcing rib 5 is provided with a through hole 53; the bottom plate 1 is further provided with a second sliding groove 12; the second sliding groove 12 is arranged in parallel on the inner side of the pair of first sliding grooves 11; the screw cap of the fastening bolt 51 is slidably connected with the second sliding groove 12; the screw rod of the fastening bolt 51 is connected with the fastening nut 52 after penetrating through the through hole 53. After the reinforcing rib 5 is fixed, it can limit the lateral movement of the clamping plate mechanism 3, that is, it can strengthen the lateral limitation of the clamping plate mechanism 3 on the basis of friction braking; at the same time, the reinforcing rib 5 can enhance the structural strength of the clamping plate mechanism 3, improve the overall stability of the bevel positioning device for plate body flame cutting, and further improve the processing adaptability to large plate bodies. Of course, the top end height of the reinforcing rib 5 should be lower than the groove bottom height of the clamping groove 41, so as to avoid the reinforcing rib 5 from touching the bottom end of the plate body and affecting the placement position accuracy of the plate body.

[0066] Further, the first sliding groove 11 is a square groove, and the sliding block 35 is a square block. The limiting strength of the square groove and the square block is high, which further improves the processing adaptability of the bevel positioning device for plate body flame cutting to large plate bodies.

[0067] In another embodiment, the bevel positioning device for plate body flame cutting further comprises a fixed-point bolt 8; a plurality of connecting holes 111 are formed in the first sliding groove 11 along the lateral direction; the clamping plate mechanism 3 is threadedly connected with the bottom plate 1 through the fixed-point bolt 8, and the fixed-point bolt 8 penetrates through the connecting hole 111. Referring to FIGS. 9 and 10, a plurality of drill holes 13 are formed on the side plate of the bottom plate 1 along the lateral direction, and the drill holes are in communication with the first sliding groove 11; the connecting hole 111 is formed on the side wall of the first sliding groove 11. The fixed-point bolt 8 penetrates through the drill hole 13, penetrates through the connecting hole 111 (i.e., the sliding block 35), and is threadedly connected with the bottom plate 1, thereby completing the fixation of the clamping plate mechanism 3 on the bottom plate 1. The positions of the plurality of connecting holes 111 are arranged according to the sizes of different models of plate bodies to be processed, and the fixed-point bolt 8 can quickly and accurately complete the installation of the clamping plate mechanism 3 on the bottom plate 1 through the drill hole 13 and the connecting hole 111.

[0068] Optionally, referring to FIG. 11, a drill hole 13 is formed in the vertical direction on the clamping plate mechanism 3, a connecting hole 111 is formed on the bottom surface of the first sliding groove 11, the fixed-point bolt 8 is inserted from the top surface of the clamping strip 4, sequentially passes through the drill hole 13 and the connecting hole 111, and is then screwed with the bottom plate 1, so that the fixed-point installation of the clamping plate mechanism 3 on the bottom plate 1 can be quickly completed.

A hole is drilled from the bottom surface of the bottom plate 1, and the reinforcing bolt 6 is screwed with the bottom end of the baffle 2.

In other working conditions, the length of the plate body is relatively long, and the baffle 2 can be disassembled to process the plate body with a relatively long length, thereby further improving the processing adaptability of the bevel positioning device for plate body flame cutting to plate bodies with different sizes.
