Description

Technical Field

[0001] This application relates to the field of machining, and in particular to a fixing device for machining the sand settling nozzle of a hydrocyclone. Background Technology

[0002] A hydrocyclone separator nozzle is a component of a device used for separating sediment and sand, and is typically used in conjunction with a hydrocyclone.

[0003] During hydrocyclone operation, mixtures (such as those containing gypsum particles and water) generate a swirling field inside the hydrocyclone. Larger particles tend to accumulate inside the equipment, causing blockages and affecting production efficiency. The underflow nozzle captures these heavy particles and ejects them outside the equipment, preventing particle accumulation inside the hydrocyclone and ensuring stable operation. By discharging heavy particles from the swirling field, it reduces the mixing of substances within the field, making it easier for lighter particles to separate. Thus, the hydrocyclone can more efficiently perform solid-liquid separation or the separation of fine sand from slurry.

[0004] The machining of hydrocyclone undercut nozzles involves processing the end faces and inner surfaces, such as cutting and drilling. However, in conventional machining, lathe chucks can only hold short outer diameters and cylindrical outer diameters. For hydrocyclone conical undercut nozzles with both inner and outer conical surfaces and a relatively high height, standard lathe chucks cannot hold and adjust them, thus making it impossible to machine hydrocyclone conical undercut nozzles. Summary of the Invention

[0005] This application provides a fixing device for processing hydrocyclone underflow nozzles, which solves the technical problem that existing underflow nozzles that are conical both inside and out and have a high height cannot be clamped for processing.

[0006] A fixing device for processing hydrocyclone underflow nozzles includes:

[0007] The base plate provides a supporting benchmark;

[0008] The first support column is fixed to the base plate;

[0009] An upper support plate is fixed to the first support column and forms a certain gap with the bottom plate; the upper support plate is provided with a first through hole penetrating the surface of the upper support plate, the axis of the first through hole is perpendicular to the surface of the bottom plate, and the diameter of the first through hole is equivalent to the outer diameter of the large end of the outer conical surface of the sand-collecting nozzle to be processed.

[0010] A pressure plate is located below the upper support plate, and the first end of the pressure plate is adapted to the bolt clearance groove of the sand discharge nozzle so that the first end of the pressure plate can be accommodated in the bolt clearance groove;

[0011] The second support column is located outside the base plate and perpendicular to the base plate. The second end of the pressure plate is fixed to the second support column. The second support column is supported by another base surface of the processing equipment that is parallel to the base plate.

[0012] Furthermore, it also includes a locking device, which includes a locking bolt;

[0013] The pressure plate is provided with a first bolt hole that penetrates the pressure plate. The bottom end of the locking bolt is vertically fixed to the base plate. The top end of the locking bolt passes through the first bolt hole and a locking nut is provided on the top end of the locking bolt.

[0014] Furthermore, the number of pressure plates and the number of locking devices are the same as the number of bolt clearance slots.

[0015] Furthermore, it also includes an axial adjustment assembly, which includes an adjustment plate that is vertically fixed to the base plate. The adjustment plate is provided with a plurality of second bolt holes perpendicular to the radial direction of the first through hole, and adjustment bolts are disposed in the second bolt holes.

[0016] Furthermore, the pressure plate body is a long straight rod, and in the vertical direction, a step is formed between the first end of the pressure plate and the pressure plate body, and the vertical dimension of the pressure plate body is larger than that of the first end.

[0017] Furthermore, the first bolt hole is a waist-shaped hole, and the arrangement direction of the waist-shaped hole is along the length direction of the pressure plate body.

[0018] Furthermore, the second bolt holes are evenly distributed around the axial circumference of the first through hole.

[0019] Furthermore, there are multiple second bolt holes, and the distances between the multiple second bolt holes and the base plate in the vertical direction are multiple.

[0020] Furthermore, there are four second bolt holes, of which two adjacent holes in the circumferential direction are located at a first height from the base plate, and the other two are located at a second height from the base plate, with the first height being higher than the second height.

[0021] Furthermore, the first support columns are evenly arranged around the outer periphery of the upper support plate, and the first through hole is located at the center of the upper support plate.

[0023] The present invention provides a fixing device for machining a hydrocyclone undercut nozzle, which can fix the undercut nozzle on a CNC vertical lathe and perform circumferential and axial clamping and positioning, thereby enabling it to be installed on the vertical lathe for turning.

[0034] like Figure 1 The shown sedimentation nozzle 1 includes a conical body and a flange structure 1-2 is provided at the large end of the conical body. The flange structure 1-2 is provided with flange bolt holes 1-4 for connecting the sedimentation nozzle 1 to the hydrocyclone. A bolt clearance groove 1-3 is provided on the side wall of the sedimentation nozzle 1 at the position corresponding to the flange bolt holes 1-4 to accommodate bolts that extend out of the flange bolt holes 1-4.

[0035] The processing of the undercut nozzle 1 involves machining steps at the end face of the flange structure 1-2 and the inner conical surface of the undercut nozzle 1. This embodiment provides the following... Figure 2 The diagram shows a fixing device 2 for processing a hydrocyclone underflow nozzle 1, used to fix the underflow nozzle 1 for easy processing.

[0036] like Figure 2 The diagram shows a structural schematic of a fixing device 2 for processing a hydrocyclone underflow nozzle 1. The fixing device 2 includes:

[0037] The base plate 2-1 provides a supporting reference. In this embodiment, the base plate 2-1 is a circular plate with its upper and lower sides flat.

[0038] The first support column 2-12 is fixed on the base plate 2-1. In this embodiment, the first support column 2-12 is a cuboid column structure and includes 4 columns. These 4 first support columns 2-12 are evenly arranged around the outer periphery of the upper support plate 2-5.

[0039] An upper support plate 2-5 is fixed to the first support column 2-12 and forms a certain gap with the base plate 2-1. A first through hole 2-11 is provided on the upper support plate 2-5, penetrating its surface. The axis of the first through hole 2-11 is perpendicular to the surface of the base plate 2-1, and the diameter of the first through hole 2-11 is approximately equal to the outer diameter of the larger end of the outer conical surface 1-1 of the sand-collecting nozzle 1 to be processed. In this embodiment, the first through hole 2-11 is located at the center of the upper support plate 2-5. Figure 2 As shown, the area above the first through hole 2-11 is open, allowing the small conical end of the sand sinker 1 to pass through the first through hole 2-11 from above until the bottom surface of the flange structure 1-2 at the large conical end of the sand sinker 1 presses against the upper surface of the upper support plate 2-5 outside the first through hole 2-11. In this way, the main body of the sand sinker 1 is housed between the upper support plate 2-5 and the bottom plate 2-1, exposing the flange structure 1-2 to be processed and the inner conical surface of the sand sinker 1 to facilitate the feed of the lathe tool head.

[0040] The pressure plate 2-3 is located below the upper support plate 2-5, and the first end 2-8 of the pressure plate 2-3 is adapted to the bolt clearance groove 1-3 of the sand discharge nozzle 1 so that the first end 2-8 of the pressure plate 2-3 can be accommodated in the bolt clearance groove 1-3.

[0041] The second support column 2-2 is located outside the base plate 2-1 and perpendicular to the base plate 2-1. The second end of the pressure plate 2-3 is fixed to the second support column 2-2. The second support column 2-2 is supported by another base surface of the processing equipment that is parallel to the base plate 2-1.

[0042] like Figure 3 As shown, when the upper surface of the upper support plate 2-5 supports the flange structure 1-2 of the sand-collecting nozzle 1, the bolt clearance groove 1-3 located near the flange structure 1-2 is below the lower surface of the upper support plate 2-5. The first end 2-8 of the pressure plate 2-3 enters the bolt clearance groove 1-3 from the outside and is supported by the second support column 2-2. The pressure plate 2-3 provides axial pressure to the sand-collecting nozzle 1, making the sand-collecting nozzle 1 axially fixed more firmly and convenient for processing.

[0043] The fixing device 2 cleverly utilizes the structure of the sand sinker 1, and uses the flange structure 1-2 and bolt clearance groove 1-3 on the sand sinker 1 to quickly fix the sand sinker 1. The radial limit provided by the first through hole 2-11 and the axial limit provided by the first through hole 2-11 and the pressure plate 2-3 together make the processing of the sand sinker 1 with inner and outer conical surfaces 1-1 and a high height more convenient and faster.

[0044] In some preferred embodiments, such as Figure 2 As shown, the fixing device 2 also includes a locking device, which includes a locking bolt 2-4. A first bolt hole 2-7 is provided on the pressure plate 2-3, penetrating the pressure plate 2-3. The bottom end of the locking bolt 2-4 is vertically fixed to the base plate 2-1, and the top end of the locking bolt 2-4 passes through the first bolt hole 2-7, with a locking nut 2-6 disposed on the top end of the locking bolt 2-4. By tightening the locking bolt 2-4 with the locking nut 2-6, the pressure plate 2-3 applies downward pressure to the bolt clearance groove 1-3, thereby enabling the pressure plate 2-3 and the upper support plate 2-5 to achieve axial positioning of the sand discharge nozzle 1.

[0045] In some preferred embodiments, in order to uniformly position the sand-collecting nozzle 1 axially, the number of pressure plates 2-3 and the number of locking devices are the same as the number of bolt clearance slots 1-3.

[0046] In some preferred embodiments, since the height of the settling nozzle 1 is relatively large, an axial adjustment assembly is also included. The axial adjustment assembly includes an adjustment plate, which is vertically fixed to the base plate 2-1. The adjustment plate is provided with a plurality of second bolt holes 2-13 perpendicular to the radial direction of the first through hole 2-11, and adjusting bolts are disposed in the second bolt holes 2-13. Figure 2 As shown, the axial adjustment assembly finely adjusts the axial direction of the sand-collecting nozzle 1 by adjusting the bolts, so that the sand-collecting nozzle 1 can achieve its axial direction perpendicular to the base plate 2-1, thereby facilitating accurate subsequent processing.

[0047] In some preferred embodiments, the main body of the pressure plate 2-3 is a long straight rod. In the vertical direction, a step is formed between the first end 2-8 of the pressure plate 2-3 and the main body of the pressure plate 2-3. The vertical dimension of the main body of the pressure plate 2-3 is larger than that of the first end 2-8. The stepped surface can abut against the outside of the bolt clearance groove 1-3, thereby preventing the pressure plate 2-3 from further penetrating into the bolt clearance groove 1-3, thus achieving accurate assembly between the pressure plate 2-3 and the bolt clearance groove 1-3.

[0048] In some preferred embodiments, the first bolt hole 2-7 is a waist-shaped hole, and the arrangement direction of the waist-shaped hole is along the length direction of the main body of the pressure plate 2-3.

[0049] In some preferred embodiments, to ensure accurate axial adjustment of the underflow nozzle 1, it is necessary to consider providing adjusting bolts in multiple directions. Therefore, as... Figure 2 As shown, the second bolt holes 2-13 are evenly distributed around the axial circumference of the first through hole 2-11, so that coordinated adjustment can be achieved by coordinating and adjusting multiple axial bolts.

[0050] In some preferred embodiments, since the outer diameter of the sink nozzle 1 is tapered, to prevent misalignment between the outer conical surfaces 1-1 at different positions of the sink nozzle 1 due to machining errors or other reasons, multiple second bolt holes 2-13 are provided. These multiple second bolt holes 2-13 are located at multiple vertical distances from the base plate 2-1. By setting different vertical distances between the second bolt holes 2-13 and the base plate 2-1, the contact between the bolts and the outer conical surfaces 1-1 at multiple positions can be adjusted, thereby reducing the possibility of inaccurate axial adjustment caused by inaccurate dimensions of the outer conical surface 1-1 at a certain height.

[0051] like Figure 3 As shown, in this embodiment, two first adjusting plates 2-9 and two second adjusting plates 2-10 are provided. The first adjusting plate 2-9 has a higher plate surface, and the second adjusting plate 2-10 has a lower plate surface. Each adjusting plate is provided with one second bolt hole, that is, there are a total of four second bolt holes 2-13. Two of them are adjacent in the circumferential direction on the first adjusting plate 2-9, at a first height from the bottom plate 2-1, and the other two are located on the second adjusting plate 2-10, at a second height from the bottom plate 2-1. The first height is higher than the second height. During each adjustment, it is preferable to adjust the two adjusting bolts that are diagonally opposite in the circumferential distribution to achieve coaxiality between the circular tangents at different heights. After multiple adjustments, the axial direction of the entire sand-collecting nozzle 1 is made perpendicular to the bottom plate 2-1.

[0052] The sand-collecting nozzle 1 is fixed by the aforementioned fixing device 2. First, the sand-collecting nozzle 1 is placed into the first through hole 2-11 and the flange structure 1-2 is pressed onto the upper support plate 2-5. At this time, the axial direction of the sand-collecting nozzle 1 can be detected by the verticality detection to determine whether it is perpendicular to the bottom plate 2-1. If it is not perpendicular, the axial angle of the sand-collecting nozzle 1 is finely adjusted by adjusting the bolts until the axial direction of the sand-collecting nozzle 1 is perpendicular to the bottom plate 2-1. Finally, the pressure plate 2-3 is inserted into the bolt clearance groove 1-3 and axially locked by the locking device to complete the fixing of the sand-collecting nozzle 1.

[0053] When machining is required, the entire fixing device 2 is placed on a vertical lathe, and the bottom of the second support column 2-2 is fixed and supported by the horizontal reference surface of the vertical lathe, thereby completing the fixing of the entire fixing device 2 on the lathe. After that, lathe machining can begin, including but not limited to drilling, turning, chamfering, etc. on the end face of the flange structure 1-2 of the sand sink 1.

[0054] The above are merely embodiments of this application and are not intended to limit the scope of this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of the claims of this application.
