Description

Technical Field

[0001] This utility model relates to the field of equipment for preventing welding deformation in mechanical manufacturing production sites. It is mainly used to prevent deformation of the left and right side plates of the head frame and tail frame, and to ensure that the size of the slot is within the required range. Background Technology

[0002] During production, thermal deformation occurs during welding. To ensure the slot width between the left and right side plates of the head frame and tail frame, 30mm diameter round steel is typically welded between the side plates for one-time tensile support. However, stress is difficult to release during production, significantly impacting subsequent processes. The round steel needs to be pre-processed to the required dimensions. After welding, the round steel must be cut off, and the cut areas must be ground. This process is labor-intensive, and since the round steel is a disposable item, it is prone to waste. Summary of the Invention

[0003] The purpose of this utility model is to provide a slot support device for the head frame and tail frame of a conveyor, which can replace the one-time round steel tensioning in the production process of the head frame and tail frame of the conveyor. The length of the support can be adjusted according to the slot width, and the slot width data can be accurately read. In actual production, it can be finely adjusted at any time according to the process requirements to release the stress generated in the production process, and has wider applicability.

[0004] The purpose of this utility model is achieved through the following technical solution: including a bidirectional control handle 1, a left-hand screw 2, a square tube 3, a plate 4, a top-tightening plate 5, a top-tightening bolt 6, a ruler base 7, a ruler base knob 8, a handle 9, a ruler 10, a ruler mark 11, a reinforcing plate 12, and a right-hand screw 13.

[0005] The bidirectional control handle 1 has three cylinders connected to the side wall of the cylinder. These three cylinders are evenly divided into three positions at an angle of 360°. The cylinder cavity is equipped with a left-hand wire 2 and a right-hand wire 13. The left-hand wire 2 and the right-hand wire 13 are connected inside the bidirectional control handle 1 to form the control assembly.

[0006] The ruler base 7 has a T-slot. The ruler 10 is assembled in the wide part of the T-slot. The ruler base knob 8 is inserted into the narrow part of the T-slot, in contact with one end of the ruler 10, and rests against the innermost part of the ruler base, forming a measuring assembly. The measuring assembly is connected to one of the square tubes 3, and the ruler mark 11 is connected to the other square tube 3.

[0007] Plate 4 is connected to both ends of the two square tubes 3 respectively. Two top clamping plates 5 are installed on the outermost sides of the two square tubes 3. The distance between plate 4 and top clamping plate 5 matches the thickness of the side plates of the head frame and tail frame.

[0008] After plate 4 and clamping plate 5 are secured to the side plates of the head frame and tail frame, two clamping bolts 6 are installed on the two clamping plates 5 respectively to clamp the side plates of the head frame and tail frame.

[0009] The measuring range of ruler 10 is determined based on the slot width of the actual production head frame and tail frame. It is greater than the maximum slot width of the product. The graduation value is in the millimeter range, the zero mark is selected in the middle position, and the positioning reference is selected in the middle position of the two-way handle 1. The purpose of this is to enable the slot width dimension to be read quickly and conveniently.

[0010] The main advantages of this invention are: it can completely replace the one-time round steel tensioning, effectively prevent material deformation caused by uneven heat input during the welding process of the left and right side plates, accurately measure the slot width data in real time, and ensure the accuracy of the positioning reference when assembling other parts and the accuracy of the machining reference when machining.

[0012] The technical solutions of the present utility model will be described in complete and clear form below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all of them.

[0013] like Figures 1-11 As shown, a conveyor head frame and tail frame slot support device includes a bidirectional control handle 1, a left-hand screw 2, a square tube 3, a plate 4, a top-tightening plate 5, a top-tightening bolt 6, a ruler base 7, a ruler base knob 8, a handle 9, a ruler 10, a ruler mark 11, a stiffening plate 12, and a right-hand screw 13. First, assemble the ruler 10, ruler base 7, and ruler base knob 8 together to form a measuring assembly. Then, assemble the left-hand screw 2 and right-hand screw 13 with the bidirectional control handle 1 to form a control assembly. Connect the control assembly to the two square tubes 3. Assemble the top-tightening plate 5 at both ends of the two square tubes 3, and install the top-tightening bolt 6 on the top-tightening plate 5. Finally, install the measuring assembly on one square tube 3, adjust the distance using the ruler 10, and install the ruler mark 11 on the other square tube 3, ensuring that the ruler mark 11 and the measuring assembly are at the same height.

[0014] In the initial stage, the work platform is first cleaned, ensuring there are no small welding slags. The left and right side plates of the head frame or tail frame are then placed on the work platform. The riveter determines the thickness of the left and right side plates and the groove size between them. The support rod device is then placed between the left and right side plates, and the left and right side plates are secured using plate 4 and the clamping plate 5. Next, the clamping bolts 6 are used to tighten the plates against the surface of the left and right side plates. By carefully rotating the two-way control handle 1 clockwise and counterclockwise, and using the ruler 10, the grooves of the left and right side plates are precisely measured to ensure that slippage does not occur when welding other parts.

[0015] As the thermal stress inside the sheet metal is gradually released during the post-welding stage, the head and tail frames are semi-open structures, and the left and right side plates are prone to deforming outward in a V-shape. At this stage, the distance of the ruler 10 can be adjusted by using the ruler knob 8 to detect whether the left and right side plates have deformed in time and to determine the amount of deformation. This allows the welder to adjust the degree of deformation of the left and right side plates in advance and determine the installation positioning benchmark for other parts.

[0016] During the machining stage, when the cutting tool is machining the holes and grooves on the left and right side plates, the inner side of the side plates will be subjected to significant pressure from the cutting tool. The operator can ensure that the left and right side plates are always clamped by adjusting the tightening bolt 6 in real time. Secondly, the operator can use the ruler 10 to check in real time whether the grooves on the left and right side plates have changed. The operation is convenient and safe.

[0017] It should be understood that the above detailed description of the technical solutions of this utility model with reference to preferred embodiments is illustrative and not restrictive. Those skilled in the art can modify the technical solutions described in the embodiments or make equivalent substitutions for some of the technical features based on reading this utility model specification. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
