Description

TECHNICAL FIELD

[0002] A lubricating pump is a lubricating device for supplying lubricant to the lubricating part of a mechanical device. The main way of traditional lubrication is to lubricate according to the working condition of the device, such as manual greasing when the device reaches a certain maintenance period. The lubricating pump can make the maintenance and lubrication work more convenient. In the prior art, the cylinder body of the lubricating pump is generally formed by injection molding, die casting, investment casting or sand casting, and the cylinder body of the pump is generally formed by injection molding, die casting, investment casting or sand casting. The common lubricating pump cylinder body is a cylindrical body with an axial hole in the middle. The outer edge of the top and bottom of the pump body is a disc protrusion, and the bottom or sidewall of the pump body is further provided with an oil inlet hole, an oil outlet and an oil return hole. The hole positions on the pump body blank need to be precisely machined to ensure the precision, smoothness and geometric shape.

[0003] When the prior art precisely machines the pump body of the lubricating pump, a multi-process dispersed machining method is usually adopted, that is, the pump body is first roughly machined, and then the axial hole, the oil inlet hole, the oil outlet hole and the oil return hole are precisely machined by different machine tools and cutters. This results in high equipment cost and cutter cost. Moreover, the pump body needs to be clamped and positioned multiple times during the machining process, which is prone to positioning errors, thereby affecting the machining precision and coaxiality of the hole positions. In addition, during the machining of the holes (axial hole, oil outlet hole, etc.), if the metal impurities such as burrs and accumulated cuttings on the machined holes are not timely treated, the hole positions will be blocked, and the subsequent machining process will be disturbed, affecting the machining quality.

The two lifting mechanisms 8 are symmetrically arranged on both sides of the top of the turntable 5. The opposite sides of the two arc-shaped positioning components 7 are detachably connected to the output ends of the two lifting mechanisms 8. The cooling mechanism 9 includes multiple spraying components for spraying cutting fluid onto the cutting tool.

The multiple spraying components are respectively installed in the multiple slots 83, and the output ends of the multiple spraying components are all inclined downwards.

[0020] The aforementioned drive mechanism can be a motor or any device capable of driving the turntable 5 to rotate, or the drive mechanism and turntable 5 can be an existing CNC indexing turntable, which will not be elaborated further.

[0021] The drill rod mechanism 3 comprises a seat 31, a first drill rod 32 and a second drill rod 33, the seat 31 is installed on the inner wall of the machine tool 1 and faces one side of the lead screw sliding table 2, the first drill rod 32 is vertically installed on the top wall in the seat 31, and the second drill rod 33 is installed on the side wall of the seat 31, the first drill rod 32 is located above the lead screw sliding table 2, and the second drill rod 33 is horizontally arranged and faces the lead screw sliding table 2.

[0022] A boring cutter or a reamer or the like cutter can be installed on the output end of the first drill rod 32 and the second drill rod 33, and the cutter can be adaptively replaced according to actual machining requirements, wherein, when the pump body is machined, the first drill rod 32 is located directly above the groove 51, and the second drill rod 33 is located above the groove 51, therefore, the cutter on the first drill rod 32 mainly machines the shaft hole in the pump body, and the cutter on the second drill rod 33 mainly machines multiple hole positions such as the oil outlet hole on the side wall of the dry oil lubrication pump, in the actual machining process, the first drill rod 32 drills the pump body shaft hole in a vertically downward direction, and the second drill rod 33 machines the hole positions on the side of the pump body in a horizontal direction, and the second drill rod 33 can meet the diversified use requirements of the oil lubrication pump by adjusting the feed amount and the rotation speed.

[0023] The rotating table 5 is internally provided with an annular cavity 52, the annular cavity 52 is internally provided with an annular partition plate 56, the annular partition plate 56 divides the annular cavity 52 into cavity one and cavity two, a plurality of through holes 53 communicated with the annular cavity 52 are uniformly arranged on the bottom of the groove 51 in the circumferential direction, the cavity two is communicated with the plurality of through holes 53, a circulating pump is installed in the cavity one, an input end of the circulating pump penetrates through the annular partition plate 56 and is communicated with the cavity two, a first bellows 58 is connected to the output end of the circulating pump, a filter screen 57 is horizontally arranged in the cavity two and located above the input end of the circulating pump, and a water inlet pipe 59 is further connected to the output end of the circulating pump and extends to the outside of the rotating table 5.

[0024] In the prior art, the pump body of the lubrication pump is generally formed by injection molding, die casting, investment casting or sand casting, no matter which forming method is adopted, the holes on the pump body blank are rough and inaccurate, and the accuracy, smoothness and geometric shape must be ensured by subsequent machining. Therefore, the diameter of the hole must be strictly controlled within the tolerance band. If the hole diameter is too small, the shaft, bearing or valve core cannot be installed; if the hole diameter is too large, the fit is loose, causing leakage or accelerated wear, and the quality of these holes directly determines the sealing performance, efficiency and service life of the lubrication pump. In order to ensure the machining accuracy of the holes of the pump body, the pump body needs to be fixed during finishing machining, so as to ensure that the pump body does not displace or vibrate during machining, thereby avoiding hole diameter deviation caused by machining errors.

[0025] In this embodiment, before the pump body is machined, two arc-shaped positioning assemblies 7 are respectively installed on the output ends of two lifting mechanisms 8, which are preferably electric push rods or hydraulic cylinders. Further, a circular plate 10 is fixedly connected to the output end of the lifting mechanism 8, and a screw rod 11 is fixedly connected to the top of the circular plate 10. The screw rod 11 penetrates the perforated hole 76 and is threadedly connected with a nut 12 for locking and fixing the connecting plate 72.

[0026] The opposite ends of the arc-shaped positioning assemblies 7 are respectively sleeved on the screw rods 11 of the circular plates 10 of the two lifting mechanisms 8, and the arc-shaped positioning assemblies 7 are firmly locked on the circular plates 10 by rotating the nuts 12, so as to ensure the stability of the arc-shaped positioning assemblies 7 during lifting. Then, the pump body to be machined is placed at the middle position inside the groove 51 on the top of the rotary table 5, and the two arc-shaped positioning assemblies 7 are lowered and abut against the top of the pump body by the lifting mechanisms 8. The lifting mechanisms 8 drive the two arc-shaped positioning assemblies 7 to continue to move downward until the pump body is firmly pressed inside the groove 51.

[0027] Further, the arc-shaped positioning assembly 7 comprises an arc-shaped plate 71, a connecting plate 72, a fixed plate 73, an arc-shaped baffle 74, and an air pump 75 for driving the arc-shaped plate 71 to stretch and retract. The connecting plate 72 is provided with a perforated hole 76, and a sliding groove 77 is formed in the inner end of the connecting plate 72. The perforated hole 76 is sleeved on the output end of the lifting mechanism 8. The arc-shaped plate 71 is located above the groove 51. The fixed plate 73 is horizontally fixed on one side of the outer wall of the arc-shaped plate 71 and sealingly slides into the sliding groove 77. The air pump 75 is installed on one side of the connecting plate 72, and the output end of the air pump 75 penetrates the connecting plate 72 and communicates with the sliding groove 77. A cavity 78 is formed in the arc-shaped plate 71, and an arc-shaped partition plate 79 is fixedly connected in the cavity 78. A first drain pipe 80 is connected to one side of the inner wall of the arc-shaped partition plate 79. A guide groove 82 is formed in the fixed plate 73 and communicates with the cavity 78. The arc-shaped baffle 74 is fixed on one side of the bottom of the arc-shaped plate 71, and a water storage groove 84 is formed in the arc-shaped baffle 74. A plurality of water spray holes 90 are uniformly formed in the inner side of the arc-shaped baffle 74 and communicate with the water storage groove 84. A second drain pipe 81 is arranged at the bottom of the arc-shaped plate 71 and communicates with the water storage groove 84. A second bellows 91 is connected to one side of the outer wall of the fixed plate 73 close to the connecting plate 72. A water guide connector 92 is arranged at the bottom of the connecting plate 72 and connects the first bellows 58 and the second bellows 91.

[0028] In use, the lifting mechanism 8 drives the arc-shaped positioning assembly 7 to move downward, the arc-shaped plate 71 first abuts against the top of the pump body, then the drill rod mechanism 3 drives the cutter on the first drill rod 32 to move downward and pass between the two arc-shaped positioning assemblies 7, at this time, the air pump 75 is started to input gas into the chute 77, thereby pushing the fixed plate 73 and moving the arc-shaped plate 71 on the top of the pump body until the arc-shaped baffle 74 at the bottom of the arc-shaped plate 71 abuts against the two sides of the disc protrusion on the top of the pump body and pushes the pump body to move to the position of the central axis of the rotary table 5, thereby realizing positioning and fixing of the pump body and adjusting the position of the pump body to adapt to different machining requirements, then the lifting mechanism 8 drives the arc-shaped plate 71 to continue to press downward, thereby firmly fixing the pump body in the recess 51, through the above operation, not only the pump body is fixed, but also displacement or shaking of the pump body in the machining process is effectively prevented. Then, the drill rod mechanism 3 drives the cutter on the first drill rod 32 to continue to move downward into the shaft hole of the pump body and process the inner wall of the shaft hole. According to the machining requirement, the rotary table 5 can be driven to rotate by the driving mechanism to facilitate the drill rod mechanism 3 to process the shaft hole of the pump body.

[0029] In the application, through the lifting of the two arc-shaped plates 71 and the relative movement of the two arc-shaped baffles 74, not only the pump body can be limited and fixed in the longitudinal direction, but also the pump body can be limited and fixed in the transverse direction. This double-direction limiting and fixing mode improves the stability of the pump body in the machining process to avoid machining errors caused by shaking or displacement of the pump body and ensures the accuracy and quality of the shaft hole machining.

[0030] A large amount of cutting chips will be generated in the working process of the drill rod mechanism 3, part of the cutting chips will fall on the workbench 4 and part of the cutting chips will adhere to the inside of the pump body and the arc-shaped positioning assembly 7. In order to keep the machining environment clean and ensure the accuracy of subsequent machining, further, the liquid spraying assembly comprises a moving pipe 85, a limiting spring 86, an annular baffle 87, a roller 88 and a water spraying elbow 89, the moving pipe 85 is slidingly arranged in the slot 83, one side of the slot 83 is communicated with the cavity 78, the annular baffle 87 is fixedly connected to one end of the moving pipe 85, the annular baffle 87 is axially sealingly and slidingly connected with the slot 83, the limiting spring 86 is movably sleeved outside the moving pipe 85 and the two ends of the limiting spring 86 abut against the annular baffle 87 and the inner wall of the slot 83 respectively, the roller 88 is horizontally rotatably arranged at the end of the moving pipe 85 away from the slot 83 and the two ends of the roller 88 are connected with the outer wall of the moving pipe 85 through two connecting pieces respectively, and the water spraying elbow 89 is installed at the bottom of the connecting piece below the moving pipe 85 and the connecting piece is provided with a connecting hole 93 communicating the moving pipe 85 and the water spraying elbow 89.

[0031] The middle of the rotary table 5 is provided with an avoiding circular hole 54, and the inner wall of the avoiding circular hole 54 is provided with a plurality of drainage openings 55 communicating with the second cavity in the circumferential direction. When the drill rod mechanism 3 is working, the external pipeline conveying the cutting chip liquid is connected with the water inlet pipe 59, and a certain amount of cutting chip liquid is conveyed to the water inlet pipe 59 by the water pump. The cutting chip liquid is conveyed to the water guide joint 92 through the first corrugated pipe 58, and then conveyed into the second corrugated pipe 91 through the water guide joint 92. After passing through the guide groove 82, the cutting chip liquid enters the cavity 78, and then the cutting chip liquid is respectively divided into the cavity 78 on one side of the arc-shaped partition plate 79 and the water storage tank 84 inside the arc-shaped baffle 74 through the first drainage pipe 80 and the second drainage pipe 81. Then, the cutting chip liquid inside the cavity 78 and the water storage tank 84 is also sprayed to the outer wall of the first drill rod 32 through the water spraying hole 90 and the liquid spraying assembly, and flows to the cutter at the end of the first drill rod 32, and then falls into the shaft hole inside the pump body. The water storage tank 84 inside the arc-shaped baffle 74 divides the other part of the cutting chip liquid in the cavity 78 and sprays it to the outer wall of the pump body through the water spraying hole 90. In order to avoid the protrusion at the outer edge of the top of the pump body from shielding or shielding the water spraying hole 90 inside the arc-shaped baffle 74, the height of the arc-shaped baffle 74 should be greater than the height of the protrusion at the outer edge of the top of the conventional pump body. After the cutting chip liquid is sprayed to the corresponding position, on the one hand, the holes on the side wall of the pump body and the internal shaft hole can be cooled, reducing the heat generated during the working process of the drill rod mechanism 3, preventing the machining precision and the service life of the equipment from being affected due to the high temperature; on the other hand, the cutting chip liquid can flow together with the cutting chip and dust generated during the working process, and wash away these cutting chip and dust from the rest of the openings on the side wall of the pump body and the inside of the pump body.

[0032] Further, since the groove 51 is provided with a plurality of through holes 53, and the rotary table 5 is provided with an avoiding circular hole 54, and the avoiding circular hole 54 is provided with a drainage opening 55, the cutting chip liquid can be smoothly discharged into the second cavity from the through hole 53, the avoiding circular hole 54 and the drainage opening 55 after passing through the shaft hole of the pump body and the plurality of openings on the side wall of the pump body. The second cavity is provided with a filter screen 57, which filters the cutting chip liquid when it falls into the second cavity, intercepts the impurities such as cutting chip mixed therein, and filters the cutting chip liquid. The filtered cutting chip liquid will accumulate at the bottom of the second cavity, and then be recycled by the circulating pump. The water inlet pipe 59 can continuously supplement new cutting chip liquid to avoid the cutting chip liquid from being reduced due to continuous consumption during the recycling process, thereby ensuring sufficient supply of cutting chip liquid during the entire machining process. In addition, the new cutting chip liquid supplemented by the water inlet pipe 59 and the recycled cutting chip liquid are mixed, which can also adjust the temperature and concentration of the cutting chip liquid, so that it always maintains the best state suitable for machining.

[0033] It is worth noting that in order to facilitate the control of the flow direction and flow rate of the cutting fluid, control valves can be respectively arranged at the water inlet pipe 59, the first drain pipe 80 and the second drain pipe 81, which can be selected according to the specific use scene, and the principle thereof is a prior art which will not be described in detail herein.

[0034] The spray assembly comprises a moving pipe 85, a limiting spring 86, an annular baffle 87, a roller 88 and a water spray elbow 89. The moving pipe 85 is slidingly arranged in the slot 83, one side of which is in communication with the cavity 78. The moving pipe 85 is fixedly connected with the annular baffle 87 at one end thereof. The annular baffle 87 is in axial sealing sliding connection with the slot 83. The limiting spring 86 is movably sleeved outside the moving pipe 85, and the two ends of the limiting spring 86 are respectively in abutment with the annular baffle 87 and the inner wall of the slot 83. The roller 88 is horizontally rotatably arranged at the end of the moving pipe 85 away from the slot 83, and the two ends of the roller 88 are respectively connected with the outer wall of the moving pipe 85 through two connecting members. The water spray elbow 89 is installed at the bottom of the connecting member below the moving pipe 85, and a connecting hole 93 is formed in the connecting member to communicate the moving pipe 85 and the water spray elbow 89.

[0035] The bottom of the water spray elbow 89 is obliquely arranged, and the water outlet of the water spray elbow 89 is directed to the position of the shaft center of the pump body.

[0036] The plurality of spray assemblies are uniformly arranged along the inner side of the arc-shaped plate 71. Therefore, before the arc-shaped plate 71 is moved to position and fix the pump body, the cutter at the end of the first drill rod 32 is lowered to the shaft hole in the pump body, and then the fixed plate 73 is moved by the air pump 75, thereby driving the arc-shaped plate 71 to move away from the outer wall of the first drill rod 32. At this time, the plurality of rollers 88 first abut against the outer wall of the first drill rod 32. When the rollers 88 continue to move, the moving pipe 85 is axially slid in the slot 83 and the limiting spring 86 is compressed through the rolling contact between the rollers 88 and the outer wall of the first drill rod 32, thereby driving the water spray elbow 89 at the bottom of the connecting member to move backward to adjust the position of the water spray elbow 89, so that the water spray elbow 89 maintains the optimal relative distance with the first drill rod 32 and the cutter. Since the bottom of the water spray elbow 89 is obliquely arranged and the water outlet is directed to the position of the shaft center, when the first drill rod 32 is lowered to the middle position in the pump body, all the water spray elbows 89 are directed to the first drill rod 32 and spray the cutting fluid onto the first drill rod 32, and the cutting fluid flows along the outer wall of the first drill rod 32 to the machining contact area between the cutter and the pump body. When the plurality of spray assemblies work synchronously, the rollers 88 are arranged along the outer periphery of the first drill rod 32, so that the cutting fluid sprayed by the water spray elbows 89 cooperates with the centrifugal force generated by the rotation of the cutter to form a spiral liquid film in the pump body. The spiral liquid film can splash against the inner wall of the pump body, thereby flushing away the cutting chips and dust adhered to the inner wall.

[0037] Since the notch 83 is in communication with the inside of the cavity 78, the cutting fluid in the cavity 78 is transported to the water spraying elbow 89 through the moving pipe 85 and the connecting hole 93, and finally uniformly sprayed on the outer wall of the first drill rod 32 and the cutter by the obliquely arranged water spraying elbow 89, so as to reduce the friction and wear of the cutter when machining in the pump body shaft hole, improve the machining precision and the service life of the cutter.

[0038] Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
