Description

Technical Field

[0001] The utility model relates to the field of auger spirals, and more specifically, it relates to a fixing fixture for an auger spiral welding workbench. Background Technique

[0002] An auger spiral is a mechanical device commonly used for material transportation. It mainly consists of spiral blades and a central rod part. The spiral blades are welded on the auger shaft to form a continuous spiral structure. When one end of the auger shaft is driven to rotate by a machine, the spiral blades rotate accordingly, thereby pushing the material to move forward along the spiral channel. The auger spiral can be applied to various industries, such as grain transportation, cement mixing, chemical raw material transportation, etc.

[0003] During the production process of the auger spiral, the spiral blades on the auger spiral need to be welded on the spiral shaft through an auger spiral welding workbench. In the prior art, during welding, one end of the spiral shaft is fixed to the transmission device on the workbench, and the other end is directly inserted into the bearing for rotational support, and then the welding operation can be carried out. However, the method of directly inserting the bearing to support the other end, although simple in operation, is prone to jamming and being difficult to disassemble, as well as the situation of slipping due to insufficient friction, which exacerbates the wear of the spiral shaft.

[0004] Therefore, in order to solve the above technical problems, this application proposes a fixing fixture for an auger spiral welding workbench. Content of the Utility Model

[0005] Aiming at the deficiencies of the prior art, the purpose of the utility model is to provide a fixing fixture for an auger spiral welding workbench.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A fixing fixture for an auger spiral welding workbench, including a central ring, which is installed inside a slewing bearing and is rotationally supported by the slewing bearing. A fixing component for fixing the spiral shaft on the auger spiral is installed on the back of the central ring, and a transmission component is installed at the bottom of the central ring so that the central ring can move along the top of the workbench.

[0007] Preferably, the fixing component includes connecting plates fixed on both sides of the back of the central ring. The bottom of the connecting plate is fixedly connected with an installation platform. A cylinder is installed on the top of the installation platform. A guide rail A is fixedly connected to the front side end of the installation platform. Both sides of the top of the guide rail A are slidably connected with sliders A. The tops of the sliders A are fixedly connected with inclined plates. The head of the cylinder is fixedly connected with a support block. An inclined groove is opened inside the inclined plate. Both sides of the support block are fixedly connected with moving blocks that are restricted inside the inclined groove through concave-convex cooperation and can slide along the inside of the inclined groove. The heads of the inclined plates are fixedly connected with arc-shaped plates.

[0008] Preferably, the transmission assembly includes an electric guide rail fixed to the top of the workbench for driving the sliding of slider B, and the top of the slider B is connected to the bottom end of the slewing bearing.

[0009] Preferably, a lifting assembly is installed between the slider B and the slewing bearing, which has higher applicability.

[0010] Preferably, the lifting assembly includes an outer column fixed to the top of the slider B, and an inner column is slidably connected inside the outer column. The top of the inner column is fixed to the bottom of the slewing bearing. A through groove is provided at a position near the top of the surface of the outer column. A plurality of insertion slots arranged in a vertical array are provided on the surface of the inner column. An insertion block is installed at the opening of the through groove, and the insertion block sequentially passes through the through groove and is inserted into the insertion slot.

[0011] Preferably, a sliding rod for the sliding of a sliding sleeve is welded below the through groove on the surface of the outer column. The top of the sliding sleeve is fixedly connected to a moving plate, and the insertion block is fixed on the surface of the moving plate. Through the restriction of the sliding sleeve and the sliding rod, the insertion block and the through groove can always be in a flush state.

[0012] Preferably, a handle for facilitating the pulling of the insertion block is fixedly connected to the back of the moving plate, which is more convenient for the staff to operate.

[0013] Compared with the prior art, the present utility model has the following beneficial effects:

[0014] 1. For the present utility model, the end of the spiral shaft opposite to the connection with the workbench is fixed and supported by a fixing component. When the spiral shaft rotates, it drives the rotation of the central ring through the fixing component, and the central ring rotates along the inside of the slewing bearing to complete the rotational support of the end of the spiral shaft. Compared with the method of directly inserting into the bearing, it can be firmly fixed by the fixing component without slipping. As long as the fixing of the spiral shaft by the fixing component is released, the spiral shaft can be easily removed without getting stuck, thus solving the problems in the background art that although the method of directly inserting into the bearing to support the other end is simple in operation, it is easy to get stuck and difficult to disassemble, and the friction is insufficient and slips, which aggravates the wear of the spiral shaft.

[0015] 2. For the present utility model, a lifting assembly is installed between the slider B and the slewing bearing, so that this fixing fixture can adjust the fixing height of the end of the spiral shaft according to different workbenches, and has higher applicability.

[0016] 3. For the present utility model, when the insertion block passes through the through groove, no alignment is required. Through the restriction of the sliding sleeve and the sliding rod, the insertion block and the through groove can always be in a flush state. Description of the Drawings

Specific embodiments

[0024] As Figures 1-5 shown, the present utility model provides a fixing fixture for a screw conveyor welding workbench, including a central ring 1, which is installed inside a slewing bearing 2 and is rotationally supported by the slewing bearing 2. A fixing component 3 for fixing the spiral shaft on the screw conveyor is installed on the back of the central ring 1. A transmission component 4 is installed at the bottom of the central ring 1 to enable the central ring 1 to move along the top of the workbench. The transmission component 4 includes an electric guide rail 41 fixed to the top of the workbench to drive the slider B 42 to slide, and the top of the slider B 42 is connected to the bottom of the slewing bearing 2.

[0025] During use, one end of the spiral shaft is fixed to the central ring 1 through the fixing component 3. Then, the slider B42 is driven to move by the electric guide rail 41, so as to move the central ring 1 on the workbench. The other end of the spiral shaft fixed to the central ring 1 is inserted into the fixed part of the workbench, and this end is fixed by the workbench. During subsequent processing, the device on the workbench can drive the rotation of the spiral shaft, so as to continuously change the angle and weld with the spiral blade. In this way, the fixing component 3 fixes and supports the opposite end of the spiral shaft connected to the workbench. When the spiral shaft rotates, it will drive the rotation of the central ring 1 through the fixing component 3, and the central ring 1 rotates inside the slewing bearing 2 to complete the rotational support of the end of the spiral shaft. Compared with the way of directly inserting into the bearing, it can be firmly fixed through the fixing component 3 without slipping. As long as the fixing of the spiral shaft by the fixing component 3 is released, the spiral shaft can be easily removed without getting stuck.

[0026] The fixing component 3 includes connecting plates 31 fixed to both sides of the back of the central ring 1. The bottom of the connecting plate 31 is fixedly connected with a mounting table 32. The top of the mounting table 32 is equipped with a cylinder 33. The front side end of the mounting table 32 is fixedly connected with a guide rail A34. Both sides of the top of the guide rail A34 are slidably connected with sliders A35. The tops of the sliders A35 are fixedly connected with inclined plates 36. The head of the cylinder 33 is fixedly connected with a support block 37. An inclined groove 38 is formed inside the inclined plate 36 (in the attached drawing, the inclined plate 36 is composed of two welded plates, one with an inclined groove 38 inside and the other connected to the arc plate 310). Moving blocks 39 are fixedly connected to both sides of the support block 37 and are restricted inside the inclined groove 38 by a concave-convex matching method and can slide along the inside of the inclined groove 38. The heads of the inclined plates 36 are fixedly connected with arc plates 310.

[0027] When fixing the end of the spiral shaft, first place the end of the spiral shaft between the two arc plates 310. Then, the controller is used to control the extension of the cylinder 33. The cylinder 33 drives the support block 37 to move forward. The moving blocks 39 on the support block 37 move along the inside of the inclined groove 38, so as to reduce the distance between the two inclined plates 36 (the two inclined plates 36 are pulled towards the middle part by the moving blocks 39). The inclined plates 36 drive the movement of the sliders A35, and the sliders A35 slide along the guide rail A34 to maintain the linear movement of the inclined plates 36. The inclined plates 36 can linearly drive the two arc plates 310 to move towards the middle part to fix the end of the spiral shaft. On the contrary, by controlling the contraction of the cylinder 33 through the controller, the two arc plates 310 are driven to move towards both sides to release the fixation of the spiral shaft, and the operation is relatively simple.

[0028] A lifting component 5 is installed between the slider B42 and the slewing bearing 2. In this way, this fixed fixture can adjust the fixed height of the end of the screw shaft according to different workbenches, with higher applicability. The following is the specific structure of the lifting component 5: The lifting component 5 includes an outer column 51 fixed to the top end of the slider B42, and an inner column 52 is slidably connected inside the outer column 51. The top end of the inner column 52 is fixed to the bottom of the slewing bearing 2. A through groove 53 is opened at a position near the top end of the surface of the outer column 51. A plurality of slot holes 54 arranged in a vertical array are opened on the surface of the inner column 52. An insertion block 55 is installed at the opening part of the through groove 53, and the insertion block 55 sequentially passes through the through groove 53 inward and is inserted into the slot holes 54. A slide rod 56 for the sliding sleeve 57 to slide is welded on the surface of the outer column 51 below the through groove 53. The top end of the sliding sleeve 57 is fixedly connected with a moving plate 58. The insertion block 55 is fixed on the surface of the moving plate 58. A handle 59 for facilitating the pulling of the insertion block 55 is fixedly connected to the back surface of the moving plate 58.

[0029] That is, by pulling the slewing bearing 2 and the center ring 1 up and down, the up and down movement of the inner column 52 is driven, the inner column 52 moves up and down along the outer column 51, and at the same time, the center ring 1 also drives the up and down movement of the fixing component 3, so as to achieve the purpose of adjusting the fixed height of the end of the screw shaft. After the height adjustment is completed, the insertion block 55 is pushed by the handle 59 to move in the direction of the through groove 53. The insertion block 55 drives the movement of the sliding sleeve 57 through the moving plate 58, and the sliding sleeve 57 slides along the slide rod 56 to maintain the linear movement of the insertion block 55. (In this way, when the insertion block 55 passes through the through groove 53, no alignment is required. Due to the limitation of the sliding sleeve 57 and the slide rod 56, the insertion block 55 and the through groove 53 can always be in a flush state). The insertion block 55 passes through the through groove 53 on the outer column 51 and is inserted into the slot holes 54 at the corresponding height of the inner column 52 to realize the fixation of the inner column 52 and the outer column 51. On the contrary, by pulling out the insertion block 55 from the slot holes 54 and the through groove 53 with the handle 59, the adjustment of the fixed height of the end of the screw shaft can be continued.

[0030] The above is only a preferred embodiment of the present invention, and it does not impose any form of limitation on the present invention; any ordinary technician in the industry can smoothly implement the present invention according to the instructions shown in the drawings and the above description; however, any minor changes, modifications and evolutions made by those skilled in the art within the scope of the technical solution of the present invention by using the technical content disclosed above are equivalent embodiments of the present invention; at the same time, any equivalent changes, modifications and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
