Description

Technical Field

[0001] This application relates to the field of hole-opening equipment technology, and in particular to a hole-opening device for preventing overheating of a circulating cooling chemical pump. Background Technology

[0002] In process industries such as chemical, petroleum, and energy, circulating-cooled chemical pumps are critical core equipment. During the manufacturing, repair, or modification of their pressure-bearing components, such as the pump body and end covers, on-site drilling is frequently required to add instrument interfaces, vent valves, or safety devices. The precision and quality of these drilling operations directly affect the sealing performance, operational safety, and service life of the chemical pump.

[0003] In the maintenance or modification of circulating-cooled chemical pumps, traditional methods face significant challenges when adding interfaces or venting holes. Firstly, positioning relies heavily on manual marking and center punching, which struggles to guarantee accuracy and consistency on complex curved surfaces, easily leading to subsequent drilling deviations. Furthermore, surface reflections or oil contamination can cause hole position shifts. During drilling, the contact point between the drill bit and workpiece is prone to micro-deformation or hardening due to localized high temperatures, affecting hole wall quality. Additionally, coolant is often poured only after drilling begins, resulting in cooling delays and exacerbating drill bit wear and overheating risks. Moreover, existing equipment struggles to achieve rapid and stable pre-marking for complex or curved workpieces, leading to inaccurate subsequent hole placement and even requiring reprocessing, reducing production efficiency and increasing costs. Therefore, a circulating-cooled chemical pump overheat protection hole-opening device is proposed to address these issues. Summary of the Invention

The roller rolls in cooperation with the guide ramp to achieve left and right adjustment of the lifting rod.

[0009] Optionally: The bottom side bolts of the lifting rod are fixed with a connecting frame connected to the fastening structure, and the fastening structure achieves clamping and locking of the fixed point rod by the drive of the lifting mechanism; The fastening structure includes an annular seat and a clamping sleeve distributed vertically. An elastic block is fixed to the bottom side of the annular seat, and a clamping block is inserted into the inner side of the elastic block. An extrusion slope is provided on the inner side of the clamping sleeve, and an abutment slope that abuts against the extrusion slope is provided on the outer side of the elastic block.

[0010] Optionally: the clamping sleeve is fitted onto the outer surface of the fixed rod, the annular seat is fixed to the bottom side of the inner shell, and both the annular seat and the clamping sleeve are hollow inside, and the connecting frame is bolted to the outer surface of the clamping sleeve.

[0011] Optional: The outer side of the abutting block is provided with a guide slope two for use with the other end of the abutting rod, and the end of the abutting rod away from the roller is provided with a ball bearing that abuts against the guide slope two.

[0013] Optionally: a valve tube is fixed to the outer surface of the pressure cylinder, a guide component extending into the interior of the fixed point rod is fixed inside the gravity block, and the top outer surface of the guide component is fixedly connected to the end of the valve tube, and a conveying channel for use with the guide component is opened inside the fixed point rod.

[0014] Optionally, the guide assembly includes a cylindrical guide rod with a connected conveying groove 1 and a conveying groove 2 inside the guide rod. A compression piston for use with the electric telescopic rod for lifting is provided on the top side of the conveying groove 1. A compression block is fixed on the top side of the compression piston, and a return spring 2 is fixed between the compression block and the guide rod.

[0015] In summary, this application includes at least one of the following beneficial technical effects: 1. This invention features multiple marking methods. It can either move the entire housing downwards via a linear module to make the marking rod contact the part for marking, or use an electric telescopic rod to extend and retract for marking, increasing operational flexibility and adaptability. When the electric telescopic rod moves upwards, the gravity block, after being lifted a certain distance, quickly strikes the marking rod in conjunction with the deformation of the gravity spring and gravity, effectively improving the marking effect of the marking rod.

[0016] 2. This invention stores the potential energy of gravity and elasticity during the lifting process, and converts it into kinetic energy on the fixed rod at the moment of release, producing a clearer, deeper and more penetrating mark than static downward pressure, further improving the drilling effect on hardened or curved surfaces.

[0017] 3. This invention not only prevents the fixed-point rod from shaking, but also, during positioning, the inner pressing slope of the clamping sleeve cooperates with the outer abutting slope of the elastic block to generate a uniform and powerful clamping force on the fixed-point rod, effectively preventing the fixed-point rod from shaking during the drilling process, ensuring positioning stability, and improving drilling accuracy.

[0018] 4. This invention also provides lubrication and cooling functions. When marking a point, it enables the intake and pumping of liquid, allowing a very small amount of coolant to seep out from the cone tip of the marking rod to lubricate the marking point, making the marking clearer and reducing cone tip wear. At the same time, coolant is pre-placed at a precise location before drilling begins, so that the drill bit is immediately cooled and lubricated when it falls, improving drilling quality and protecting the drill bit from overheating.

[0019] 5. This invention has the effect of cleaning the marking point. During the upward movement of the gravity block, the guide component operates synchronously. The extrusion block abuts against the top wall of the inner shell, causing the extrusion piston to move downward, generating a brief pneumatic pulse, which blows away the oil, dust and iron filings from the previous process at the marking point, ensuring clear marking by the fixed point rod.

[0022] The following is in conjunction with the appendix Figures 1-9 This application will be described in further detail.

[0023] Example 1, as Figures 1-3 As shown, this is the first embodiment of the present invention. This embodiment provides a circulating cooling chemical pump anti-overheating hole-opening device, which includes an upper base 11, a lower base 12, a processing table 13, a housing 14, a linear module one 15, a linear module two 16 and a drill bit 17. The housing 14 is composed of an outer shell 141 and an inner shell 142, and the drill bit 17 is located inside the inner shell 142. It should be noted that the upper base 11 and the lower base 12 are arranged in the X and Y axis directions, and the upper base 11 is bolted to the upper surface of the lower base 12. There are two linear modules 15 and two linear modules 16. The linear modules 16 are arranged in the X and Y axis directions, and the processing table 13 is fixed on one of the linear modules 16. In this embodiment, the outer shell 141 and the inner shell 142 are hollow. The inner shell 142 is provided with a rotating mechanism for driving the drill bit 17 to rotate. Specifically, the two linear modules 15 are located on the upper base 11 and the outer shell 141, respectively, so as to realize the lifting and lowering adjustment of the outer shell 141 and the drill bit 17.

[0024] Example 2, as Figures 2-8As shown, this is the second embodiment of the present invention. The difference from the first embodiment is that, in order to improve the hole opening effect, a fixed rod 2 is provided inside the inner shell 142 in this embodiment, and a positioning module 3 that works in conjunction with the fixed rod 2 is also provided inside the inner shell 142. Specifically, the drill bit 17 and the fixed rod 2 both extend to the bottom side of the outer shell 141, and the electric telescopic rod 5 is fixed to the top side of the inner shell 142, and its output end extends into the inner shell 142.

[0025] The positioning module 3 in this embodiment includes a gravity component 4, a lifting mechanism, and a fastening structure 7. The lifting mechanism drives the gravity component 4 and the fastening structure 7 respectively. In this embodiment, the linear module 15 drives the housing 14 to move down as a whole, so that the positioning rod 2 contacts the part to mark the dot. The electric telescopic rod 5 can also be used to extend and retract to mark the dot, which increases the flexibility and adaptability of operation and has multiple dot marking methods.

[0026] like Figures 4-6 As shown, the gravity component 4 is located on the top side of the fixed-point rod 2. The gravity component 4 includes a gravity block 41 and two pads 42. The two pads 42 are fixed to the fixed-point rod 2 and the opposite side of the gravity block 41, and a gravity spring 43 is fixed to the opposite side of the fixed-point rod 2 and the gravity block 41. In use, when the electric telescopic rod 5 moves upward, the gravity block 41 is lifted a certain distance, and then, in conjunction with the deformation of the gravity spring 43 and gravity, it quickly strikes the fixed-point rod 2, effectively improving the marking effect of the fixed-point rod 2. Specifically, a rubber pad is installed between the two pads 42 to reduce damage to the fixed-point rod 2 and extend its service life. At the same time, the cushioning of the rubber pad can make the striking force act more evenly on the fixed-point rod 2, further improving the quality of the dot marking.

[0027] It is worth mentioning that in the machining of circulating cooling chemical pump parts, dot marking can provide precise positional guidance for subsequent drilling operations. For parts with complex shapes, dot marking can serve as an auxiliary positioning method. Marking different key locations on the part helps operators better understand the part's machining contour and the relative positional relationships between its parts, thus enabling more accurate subsequent machining operations. For example, when machining mechanical parts with irregular curved surfaces, dot marking can clearly define the position and boundaries of each machining surface, improving machining accuracy.

[0028] The lifting mechanism in this embodiment includes an electric telescopic rod 5, a guide 6, and an abutment 8. A lifting rod 51 is fixed to the output end of the electric telescopic rod 5. It should be noted that the guide 6 is located on one side of the lifting rod 51, and the guide 6 guides and adjusts the abutment 83. Figure 4 and Figure 6As shown, the guide 6 includes a partition 61 fixed inside the inner shell 142. A guide seat 62 is fixed inside the partition 61. A guide slope 63 is provided on the side of the guide seat 62 near the abutment 8. It should be noted that the slope of the guide slope 63 becomes narrower as it goes up, so that it can cooperate with the upward movement of the electric telescopic rod 5 to drive the abutment 8, so that it acts on the gravity component 4 and improves the marking effect.

[0029] To improve the marking effect, a connecting bracket 52 connected to the fastening structure 7 is bolted to the bottom side of the lifting rod 51. The fastening structure 7, driven by the lifting mechanism, achieves clamping and locking of the fixed-point rod 2; Figures 4-7 As shown, the fastening structure 7 includes an annular seat 73 and a clamping sleeve 71 distributed vertically. An elastic block 74 is fixed to the bottom side of the annular seat 73, and a clamping block 75 is inserted into the inner side of the elastic block 74. A pressing inclined surface 72 is provided on the inner side of the clamping sleeve 71, and an abutting inclined surface 76 that abuts against the pressing inclined surface 72 is provided on the outer side of the elastic block 74. In this embodiment, when the lifting rod 51 drives the connecting frame 52 to move, thereby enabling the fastening structure 7 to function, the clamping sleeve 71 moves closer to the annular seat 73 under the action of the lifting mechanism. The pressing inclined surface 72 and the abutting inclined surface 76 interact, causing the elastic block 74 to undergo elastic deformation. The clamping block 75 gradually presses against the fixed point rod 2 under the action of the elastic block 74, firmly fixing the fixed point rod 2 in the predetermined position, avoiding the position displacement of the fixed point rod 2 due to external factors or its own gravity, thereby ensuring the accuracy of the marking position.

[0030] It should be noted that during the marking process, the gravity component 4 will vibrate when it strikes the fixed point rod 2. The clamping effect of the fastening structure 7 can effectively reduce the impact of vibration on the fixed point rod 2, so that the fixed point rod 2 remains relatively stable when it is struck, thereby ensuring the clarity and accuracy of the marking. If the fixed point rod 2 shakes during the striking process, it may cause the marking to become blurry, offset, or even fail to form an effective marking. The presence of the fastening structure 7 can effectively prevent this from happening. In addition, when the anchor rod 2 is firmly fixed, the striking force can be concentrated on the end of the anchor rod 2, so as to generate a greater impact force, thereby forming a more obvious and deeper mark on the marking surface and improving the marking effect.

[0031] Specifically, the clamping sleeve 71 is fitted onto the outer surface of the fixed rod 2, the annular seat 73 is fixed to the bottom side of the inner shell 142, and both the annular seat 73 and the clamping sleeve 71 are hollow inside. The connecting bracket 52 is bolted to the outer surface of the clamping sleeve 71. It should be noted that the clamping block 75 is arc-shaped, and its inner side may be provided with anti-slip protrusions. At least two elastic blocks 74 and clamping blocks 75 are present. The elastic block 74 is made of a metal material that is elastic and has a long service life, and the fixed rod 2 may be made of hard alloy material.

[0032] like Figures 6-8 As shown, the abutting member 8 in this embodiment includes an abutting block 82 and an abutting rod 83. The abutting block 82 is elastically disposed inside the gravity block 41, and the abutting rod 83 is elastically disposed inside the lifting rod 51. One end of the abutting rod 83 is provided with a guide roller 84, wherein the roller 84 rolls in cooperation with the first guide slope 63 to realize the left and right adjustment of the lifting rod 51. Specifically, the outer side of the abutting block 82 is provided with a second guide slope 86 that cooperates with the other end of the abutting rod 83. With the provision of the second guide slope 86, when the abutting rod 83 moves above the abutting block 82, it can drive the abutting block 82 to move inward, thereby facilitating the abutting rod 83 to move below the abutting block 82 again.

[0033] Specifically, the end of the abutment rod 83 away from the roller 84 is provided with a ball bearing that abuts against the guide ramp 86. A return spring 85 is installed on both the outer wall of the abutment block 82 and the outer surface of the abutment rod 83. An extension groove 81 for the abutment block 82 is opened inside the gravity block 41, and the abutment block 82 slides in conjunction with the extension groove 81. In this embodiment, the special design of the guide ramp 63, which narrows towards the top, combined with the rolling action of the roller 84 and the deformation of the return spring 85, allows the abutment member 8 to flexibly adjust the left and right positions of the lifting rod 51 according to the different upward movements of the electric telescopic rod 5. Furthermore, by extending the slope distance of the guide ramp 63 and coordinating with the extension and retraction of the electric telescopic rod 5, the upward movement height of the gravity block 41 is adjusted, thereby adjusting the striking gravity.

[0034] Example 3, as Figure 5 , Figure 8 and Figure 9 As shown, this is the third embodiment of the present invention. Unlike the second embodiment, to improve the marking environment, this embodiment includes a suction structure 9 inside the lifting rod 51 that reciprocates with the abutment rod 83. The suction structure 9 includes a pressure cylinder 91 fixed inside the lifting rod 51. A suction seat 92 extends outward from the pressure cylinder 91. A connecting plate 94 is installed between the suction seat 92 and the abutment rod 83. The lateral displacement of the lifting rod 51 is adjusted by the abutment of the roller 84 and the guide inclined surface 63, thereby driving the suction structure 9 to perform suction and discharge operations. In this embodiment, a valve pipe 93 is fixed to the outer surface of the pressure cylinder 91. The valve pipe 93 consists of a check valve and a pipe, and there are two valve pipes 93, one of which is connected to the liquid storage tank. In this embodiment, when marking a point, liquid can be drawn in and pumped out, allowing coolant to seep out from the cone tip of the marking rod 2, lubricating the marking point, making the marking clearer, reducing cone tip wear, and pre-filling coolant at a precise position before drilling begins, so that the drill bit 17 can be cooled and lubricated immediately when it falls, improving drilling quality and protecting the drill bit 17 from overheating.

[0035] To further improve the marking environment, in this embodiment, a guide component 10 extending into the interior of the positioning rod 2 is fixed inside the gravity block 41, and the outer surface of the top end of the guide component 10 is fixedly connected to the end of the valve pipe 93. The interior of the positioning rod 2 is provided with a conveying channel 21 for use with the guide component 10. In use, the guide component 10 can not only perform pressurized gas and liquid delivery functions, but also guide the gravity block 41 so that it can move linearly.

[0036] like Figure 9 As shown, the guide assembly 10 includes a cylindrical guide rod 1001. The guide rod 1001 has a connected conveying groove 1005 and a second conveying groove 1006 inside. A compression piston 1003 is installed on the top side of the first conveying groove 1005 to cooperate with the lifting and lowering of the electric telescopic rod 5. A compression block 1002 is fixed to the top side of the compression piston 1003, and a return spring 1004 is fixed between the compression block 1002 and the guide rod 1001. It should be noted that the first conveying groove 1005 is funnel-shaped, and the second conveying groove 1006 is smaller than the first conveying groove 1005. The funnel-shaped first conveying groove 1005 facilitates the rapid entry and accumulation of the medium, while the smaller second conveying groove 1006 increases the flow rate of the medium, ensuring that the medium can be smoothly and quickly conveyed through the guide assembly 10 to the interior of the fixed rod 2. Simultaneously, when the compression piston 1003 is working, it can increase the pulse pressure and improve the cleaning effect.

[0037] Combined with appendix Figures 1-9 The working principle of the above embodiments is as follows: By cooperating with linear module 15 and linear module 2, the processing table 13 can be moved in the X and Y axis directions, thereby adjusting the hole position. When drilling, the machine housing 14 is moved down as a whole by one of the linear modules 15. At this time, the fixed point rod 2 will first contact the parts of the circulating cooling chemical pump to mark the workpiece. In addition, the electric telescopic rod 5 can also be used for marking. When the electric telescopic rod 5 moves upward, the lifting rod 51 first drives the abutment rod 83 to move upward. The displacement of the abutment rod 83 contacts the bottom side of the abutment block 82 and follows the electric telescopic rod 5 to drive the gravity block 41 to move upward. During the upward movement, the roller 84 at the end of the abutment rod 83 rolls along the guide slope 63. Since the slope of the guide slope 63 moves further away from the gravity block 41 as it goes up, the abutment rod 83 will gradually disengage from the abutment block 82 due to the deformation of the return spring 85. This allows the gravity block 41 to quickly strike the fixed point rod 2 after being lifted a certain distance, in conjunction with the deformation of the gravity spring 43 and gravity, thereby improving the marking effect of the fixed point rod 2. When the electric telescopic rod 5 moves upward, it will also drive the clamping sleeve 71 to move upward through the connecting frame 52. At this time, the clamping sleeve 71 is provided with a squeezing inclined surface 72 on the inner side and an abutting inclined surface 76 on the outer side of the elastic block 74. Under the drive of the lifting mechanism, the clamping sleeve 71 can generate a uniform and strong clamping force on the fixed rod 2 through the inclined surface cooperation, which effectively prevents the fixed rod 2 from shaking during the opening process and ensures the stability of the positioning. Meanwhile, as the abutment rod 83 moves upward, it will also drive the suction structure 9 to suck up liquid. When the electric telescopic rod 5 moves downward, as the abutment rod 83 approaches the gravity block 41, it can pump the sucked liquid into the guide assembly 10 through the valve pipe 93. The liquid enters the conveying channel 21 and is discharged along with the first conveying channel 1005 and the second conveying channel 1006. At this time, a very small amount of coolant seeps out from the cone tip of the fixed point rod 2, which not only lubricates the marking point, making the marking clearer and reducing cone tip wear, but also pre-places coolant at the precise position before drilling begins. When the drill bit 17 falls, it immediately obtains cooling and lubrication, improves drilling quality and protects the drill bit 17 from overheating. In addition, during the upward movement of gravity block 41, guide assembly 10 operates synchronously, and the extrusion block 1002 on guide assembly 10 abuts against the inner top wall of inner shell 142, causing extrusion piston 1003 to move downward, which will generate a brief pneumatic pulse, blowing away oil, dust and iron filings from the previous process at the marking point, ensuring clear marking on the fixed point rod 2.

[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
