Technical Field

[0001] The present invention relates to the technical field of turning processing of pump valves, and particularly relates to a turning device for processing pump valves. Background Art

[0002] Chinese Patent Application No. "CN202311601844.7" discloses a turning device for processing pump valves. This invention can be used for the fixed positioning of large pump valves, ensuring that there is no deviation during turning along the port, effectively reducing the machining error during turning; the replacement of the port during turning is more convenient, improving the processing efficiency.

[0003] However, in the above prior art, waste chips generated during the turning processing of pump valves will remain inside the pump valves. Due to the processing of large pump valves, it is inconvenient for manual cleaning, and the clamping part of this device lacks a waste chip collection structure, making the cleaning after processing inconvenient.

[0004] Based on the above-mentioned disadvantages in the prior art, this case will propose a new clamping mechanism for turning processing of pump valves to facilitate the cleaning of waste chips inside the pump valves and on the processing platform. Summary of the Invention

[0005] The purpose of the present invention is to solve the disadvantages in the prior art such as waste chips remaining inside the pump valves and lacking a waste chip collection structure, and to propose a turning device for processing pump valves.

[0006] To achieve the above purpose, the present invention adopts the following technical solutions:

[0007] Design a turning device for processing pump valves, including a turning device and a clamping assembly, which is arranged on one side of the tool tip end of the turning device;

[0008] The clamping assembly includes a first bracket and a second bracket arranged up and down. The first bracket and the second bracket are connected by a telescopic device. A first mounting plate is rotatably installed on one side of the second bracket. The upper end of the first mounting plate is connected to an abutting plate through a multi-joint telescopic rod. The lower end of the first mounting plate is rotatably installed with a second mounting plate. The lower end of the second mounting plate is fixedly installed with a second slide rail. At least two groups of clamping components are slidably installed at the lower end of the second slide rail. A waste material groove for storing processing waste chips is placed below the clamping components. The abutting plate can slide inside the waste material groove.

[0009] Preferably, the clamping assembly includes two sets of gears arranged oppositely. A rack is meshed between the two sets of gears. One end of the outer sides of the two sets of gears is integrally formed with clamping jaws. A fixing frame is rotatably installed between the two sets of gears. A latch is elastically slid inside the fixing frame. Multiple tooth grooves matched with the latch are formed on the outer end face of the rack. A clamping block is arranged below the two clamping jaws. A pushing device for pushing the clamping block to move forward is installed at the lower end of the clamping block. The pushing device is fixedly connected to the fixing frame through a third bracket. One end of the outer side of the fixing frame is fixedly installed with a sliding frame through a spline groove. The sliding frame is slidably connected to the second slide rail.

[0010] Preferably, an elastic member is elastically connected between the two clamping jaws. The middle part of the elastic member is rotatably clamped with the upper end of the rack.

[0011] Preferably, a plug rod is inserted upward through the inside of the rack. A return pushing member is arranged inside the plug rod. A contact plate is arranged above the plug rod. Contact rods are welded to both ends of the contact plate. One end of the contact rod penetrates above the second slide rail and the second mounting plate. A contact protrusion for movably abutting against the contact rod is installed at the lower end of the abutting plate.

[0012] Preferably, permanent magnets are nested inside both the return pushing member and the plug rod. One side of the latch is of an arc-shaped structure.

[0013] Preferably, a rotating shaft is welded to one end of the first mounting plate. The rotating shaft is rotatably installed inside the second bracket through a bearing. The rotating shaft is arranged below one end of the first mounting plate.

[0014] Preferably, a rotating frame is welded to the upper end of the second mounting plate. An installation hole 302 is vertically penetrated through the inside of the first mounting plate. The rotating frame is rotatably installed inside the installation hole.

[0015] Preferably, a first slide rail is fixedly installed at the lower end of the first mounting plate through bolts. A pulley matched with the first slide rail for sliding is fixedly installed at the upper end of the second mounting plate through bolts.

[0016] Preferably, the waste material groove is of a horn-shaped structure with an open upper end. A waste material drawer for storing waste material is slidably inserted at the lower end of the waste material groove.

[0017] Preferably, a bidirectional lead screw is installed inside the second slide rail so as to drive the clamping assemblies located on both sides to displace.

[0018] The turning equipment for pump valve processing proposed by the present invention has the beneficial effects that:

[0019] In this case, the clamping component can drive the pump valve to be machined to rotate through a rotating shaft, and this rotation can tilt the waste chips inside the pump valve to be machined and on the clamping assembly so that they fall into the waste chute, not only cleaning the waste chips inside the pump valve to be machined, but also making the collection of waste chips more convenient;

[0020] In this case, through the linkage structure of the abutting plate and the clamping component, not only can the waste chips in the waste chute be compacted by the abutting plate, but also the clamping component can be unlocked during the compaction process, making the unloading of the pump valve to be machined more convenient and facilitating the collection of waste chips at the same time;

[0021] In this case, through structures such as a rotating shaft, a telescopic device, a rotating frame, and a second slide rail, the clamping component can drive the pump valve to be machined to rotate at multiple angles, improving the cooperation effect with the turning device.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0034] Refer to Figure 1-4 , here is an example of the implementation of the main body of the clamping assembly:

[0035] A turning equipment for pump valve processing includes a turning device 1 for turning processing. A clamping assembly for clamping the pump valve to be processed is arranged at the tool tip end of the turning device 1. The clamping assembly includes a first bracket 2 and a second bracket 201 arranged up and down. The first bracket 2 and the second bracket 201 are connected by a telescopic device 202 so that the distance between them can be changed telescopically. A first mounting plate 3 is rotatably installed on one side of the upper end of the second bracket 201. The upper end of the first mounting plate 3 is connected to a contact plate 7 through a multi-section telescopic rod 303. The lower end of the first mounting plate 3 is rotatably installed with a second mounting plate 4. The lower end of the second mounting plate 4 is fixedly installed with a second slide rail 5 through bolts and other components. At least two groups of clamping components are slidably installed at the lower end of the second slide rail 5. A waste material tank 12 for storing processing waste chips is placed below the clamping components. The contact plate 7 can slide inside the waste material tank 12.

[0036] Furthermore, referring to Figure 2 , the telescopic device 202 may include a sliding column and an oil cylinder. The sliding column is used to improve the stability of the telescopic movement and play a supporting role, and the oil cylinder is used to control the telescopic length.

[0037] Furthermore, referring to Figure 4 , a rotating shaft 301 is welded to one end of the first mounting plate 3. The rotating shaft 301 is rotatably installed inside the second bracket 201 through a bearing, so that the first mounting plate 3 can rotate around the central axis of the rotating shaft 301. In order to further maximize the lowest height of the contact plate 7, the rotating shaft 301 should be arranged below one end of the first mounting plate 3. A gear 8 disc is sleeved on one side of the rotating shaft 301 through a spline groove, so that the rotating shaft 301 can be driven to rotate around its own central axis by using a motor or other devices.

[0038] Furthermore, referring to Figure 4 , a rotating frame 401 is welded to the upper end of the second mounting plate 4. An installation hole 302 is vertically penetrated through the first mounting plate 3. The rotating frame 401 is rotatably installed inside the installation hole 302. In order to be able to drive the rotating frame 401 to rotate, components such as a motor, a gear 8 box, and a worm are fixedly installed on the outer end face of the first mounting plate 3. One end of the rotating frame 401 is a worm gear structure, so as to form a worm and worm gear transmission structure to realize the driving of the rotating frame 401.

[0039] Further, referring to Figure 4 , a first slide rail 304 is fixedly installed at the lower end of the first mounting plate 3 through components such as bolts, and structures such as pulleys are fixedly installed at the upper end of the second mounting plate 4 through components such as bolts. The cooperation between the first slide rail 304 and the pulley improves the rotational stability between the first mounting plate 3 and the second mounting plate 4.

[0040] Further, referring to Figure 4 , the multi - section telescopic rod 303 is an elastic multi - section telescopic rod 303, so that the distance between the first mounting plate 3 and the abutting plate 7 can be elastically adjusted.

[0041] Further, referring to Figure 2 , the waste material trough 12 is a horn - shaped structure with an open upper end, and a waste material drawer 1201 for storing waste materials is slidably inserted at the lower end of the waste material trough 12.

[0042] Further, a bidirectional lead screw is installed inside the second slide rail 5, enabling the displacement of the clamping components located on both sides to be driven.

[0043] Based on the above, the clamping component can adjust the horizontal height driven by the telescopic device 202, can adjust the longitudinal rotation angle driven by the rotating shaft 301, can adjust the horizontal rotation angle driven by the rotating frame 401, the clamping component can adjust the distance along with the second slide rail 5, and the abutting plate 7 can extend into the interior of the waste material trough 12 driven by the telescopic device 202 and the rotating shaft 301. Therefore, during use, the clamping component can be tilted by the rotating shaft 301 to pour out the waste chips in the pump valve to be processed. When the processing is completed, the abutting plate 7 can be rotated to the lower side by the rotating shaft 301. At this time, controlling the telescopic device 202 to contract can make the abutting plate 7 enter the waste material trough 12 and compress the waste chips.

[0044] Referring to Figure 5 , 6 , here is an example of the implementation manner of the clamping component:

[0045] The clamping component includes two sets of gears 8 arranged oppositely. A rack 9 is meshed between the two sets of gears 8. At the outer ends of the two sets of gears 8, clamping claws 801 are integrally formed. A fixed frame 803 is rotatably installed between the two sets of gears 8. Referring to Figure 2 , a retaining pin 804 elastically slides inside the fixed frame 803. Multiple tooth grooves 902 that cooperate with the retaining pin 804 are formed on the outer end face of the rack 9, enabling the relative position between the rack 9 and the fixed frame 803 to be fixed, and further fixing the opening and closing size of the two clamping claws 801. Referring to Figure 6On the left part, below the two groups of clamping jaws 801, there is a clamping block 1102. At the lower end of the clamping block 1102, there is a pushing device 1101 for pushing the clamping block 1102 to move forward. The pushing device 1101 is fixedly connected to the fixed frame 803 through the third bracket 11. At the outer end of the fixed frame 803, a sliding frame 10 is fixedly installed through a spline groove, and the sliding frame 10 is slidably connected to the second slide rail 5.

[0046] Further, referring to Figure 6 , an elastic member 802 is elastically connected between the two groups of clamping jaws 801. The middle part of the elastic member 802 is rotationally clamped to the upper end of the rack 9, so that when the pump valve to be processed contacts the elastic member 802, the rack 9 can be pressed down to realize the clamping of the two groups of clamping jaws 801. At the same time, the elastic member 802 can help the two groups of clamping jaws 801 to open and reset.

[0047] Further, referring to Figure 6 , fixed frames 803 are rotatably installed on both the left and right sides of the two groups of gears 8. The two groups of fixed frames 803 are fixed by bolts. At the same time, a chute is opened on the outer end face of the rack 9, and a protrusion that can slide inside the chute is integrally formed on the outer end face of the fixed frame 803.

[0048] Further, the sliding frame 10 includes a longitudinal pulley and a transverse pulley to improve the stability between the sliding frame 10 and the second slide rail 5.

[0049] Further, referring to Figure 2 、 4 、6, a plug rod 901 is inserted upward through the inside of the rack 9. A return pushing member 903 is arranged inside the plug rod 901. The return pushing member 903 is used to push the pin 804 back so that it disengages from the tooth groove 902. Above the plug rod 901, there is a contact plate 6. At both ends of the contact plate 6, there are contact rods 601 welded. One end of the contact rod 601 penetrates above the second slide rail 5 and the second mounting plate 4. At the lower end of the abutting plate 7, there is an abutting protrusion 701 for movably abutting against the contact rod 601. When the abutting plate 7 contacts the waste material groove 12, it will elastically contract and abut against the contact rod 601. The combination of the contact rod 601 and the contact plate 6 is pressed down to contact the plug rod 901. The plug rod 901 slides, and the return pushing member 903 arranged inside the plug rod 901 pushes the pin 804 to retract. The locking contact of the plug rod 901 enables the two groups of clamping jaws 801 to open. At this time, the pump valve to be processed can be taken off;

[0050] Furthermore, as an optional item, permanent magnets are nested inside both the return pushing member 903 and the plug rod 901. When the return pushing member 903 and the plug rod 901 are misaligned, the repulsive force between the permanent magnets is less than the elastic driving force of the plug rod 901. When the return pushing member 903 and the plug rod 901 are aligned, the permanent magnets repel each other, causing the plug rod 901 to disengage from the tooth groove 902;

[0051] Furthermore, referring to Figure 2 , one side of the locking pin 804 is an arc-shaped structure, so that when the clamping jaw 801 performs the locking action, the arc surface of the locking pin 804 abuts and retracts against the tooth groove 902, forming a one-way locking structure.

[0052] Based on the examples of the above embodiments, when in use:

[0053] Rotate the rotating shaft 301 and adjust the height of the telescopic device 202 so that the abutting plate 7 faces the waste chute 12 and enters the waste chute 12 to compact the waste chips inside the waste chute 12. At the same time, the abutting protrusion 701 on the abutting plate 7 contacts the contact rod 601 on the contact plate 6. The contact plate 6 is forced downward and contacts the insertion rod 901. The return member 903 in the insertion rod 901 is aligned with the tooth groove 902, causing the locking pin 804 to rebound and disengage from the tooth groove 902. At this time, the locking can be released and the two clamping jaws 801 can open freely;

[0054] Adjust the position of the clamping jaws 801 on the second slide rail 5, place the pump valve to be processed between the two clamping jaws 801. The combination formed by the elastic member 802 and the toothed rod 9 is elastically contracted under pressure and drives the two clamping jaws 801 to contract and clamp. The pushing device 1101 pushes the clamping block 1102 forward, abuts against the pump valve to be processed and increases the clamping force of the clamping jaws 801;

[0055] After the clamping is completed, control the height through the telescopic device 202, control the longitudinal rotation angle through the rotating shaft 301, and control the horizontal rotation angle through the rotating frame 401, then the processing operation can be carried out. During the processing, the pump valve to be processed can be tilted by controlling the rotating shaft 301 to pour out the residual waste chips inside the pump valve to be processed.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
