Description

Technical Field

[0001] This application relates to the field of valve core processing technology, and specifically discloses a reaming device. Background Technology

[0002] Valves are commonly used pipeline valves in industrial production to control the flow of fluids.

[0003] A valve consists of components such as the valve body, valve cover, and valve core, with the valve core being one of the core components. The valve core controls the flow rate between the inlet and outlet through its up-and-down movement. The valve core requires reaming during machining; however, existing machining equipment often has the following shortcomings when reaming hydraulic piston pump valve cores:

[0004] First, when the drilling equipment is reaming the clamped valve core, the operator needs to spend time waiting. After the valve core is reamed, the operator has to remove the valve core and replace it with another valve core that needs to be reamed. This method has low work efficiency and cannot meet the production needs of the enterprise.

[0005] Secondly, during the valve core reaming process, the generated debris cannot be recycled. As a result, debris not only falls everywhere in the production workshop, but also creates a significant burden for the operators to clean up later.

[0006] To address the aforementioned problems, this application discloses a hole-reaming device. Utility Model Content

[0007] To overcome the shortcomings of the prior art, this application discloses a hole-reaming device.

[0008] To achieve the above objectives, the technical solution adopted in this application is: a reaming device, comprising: a platform, a base above the platform, an indexing plate above the base, and a plurality of positioning cylinders arranged in a circular array along the edge of the indexing plate.

[0010] The lifting mechanism includes a stand located on the rear side of the platform and a lifting drive assembly located on the side of the stand facing the indexing plate.

[0011] A reaming mechanism, comprising a gearbox connected to a lifting drive assembly, a spindle motor connected above the gearbox, and a reaming cutter connected to the bottom of the gearbox.

[0012] More preferably, the bottom of the positioning cylinder is provided with a waste discharge hole, and the waste discharge hole extends through the indexing plate.

[0013] A further preferred embodiment is that a waste collection box is provided on the base corresponding to the indexing plate.

[0014] More preferably, the bidirectional drive assembly is one of a bidirectional drive cylinder or a bidirectional lead screw module.

[0015] A further preferred embodiment is that the two clamping blocks each have a V-shaped groove on their opposite side.

[0016] More preferably, the lifting drive assembly is a unidirectional servo screw module.

[0017] More preferably, the gearbox contains a rotatable tool spindle and a rotatable drive shaft. The output shaft of the spindle motor extends into the gearbox and is fitted with a first gear. The tool spindle is fitted with a second gear inside the gearbox. The drive shaft is fitted with a third gear that meshes with the first gear and a fourth gear that connects to the second gear.

[0018] Further preferably, it also includes a counterweight system, which includes a counterweight block slidably disposed in the stand, two mounting seats disposed above opposite sides of the lifting drive assembly, chain gears respectively rotatably disposed on opposite sides of the two mounting seats, and two guide chains respectively meshing with the two chain gears and respectively connecting the counterweight block to the gearbox.

[0019] This application achieves the following beneficial effects:

[0020] 1. The reaming equipment provided in this application can continuously perform loading, unloading and reaming operations on valve cores, reducing the waiting time of operators, improving production efficiency, and meeting the production needs of enterprises.

[0021] 2.

[0032] Example

[0033] To address the shortcomings of existing reaming equipment used for reaming valve cores, reference is made to... Figures 1-5 As shown, this application discloses a reaming device, comprising:

[0034] A platform 10 is provided, and a base 20 is provided above the platform 10. An indexing plate 30 is provided above the base 20. Several positioning cylinders 40 are arranged in a circular array along the edge of the indexing plate 30. The operator can put the valve core to be reamed into the several positioning cylinders 40 in sequence.

[0035] The clamping fixture 50 includes a bidirectional drive assembly 51 located on the rear side of the indexing plate 30 above the base 20 and two clamping blocks 52 connected to the two drive parts of the bidirectional drive assembly 51. When the indexing plate 30 drives several positioning cylinders 40 to rotate, when a valve core is located between the two clamping blocks 52, the bidirectional drive assembly 51 will drive the two clamping blocks 52 to move towards each other, and with the cooperation of the two clamping blocks 52, the valve core can be clamped.

[0036] The lifting mechanism 60 includes a stand 61 located on the rear side of the platform 10 and a lifting drive assembly 62 located on the side of the stand 61 facing the indexing plate 30. When the valve core is clamped, the lifting drive assembly 62 will start to operate.

[0037] The reaming mechanism 70 includes a gearbox 71 connected to the lifting drive assembly 62, a spindle motor 72 connected above the gearbox 71, and a reaming cutter 73 connected to the bottom of the gearbox 71. Under the drive of the lifting drive assembly 62, the gearbox 71 will descend in real time, and the spindle motor 72 will drive the reaming cutter 73 to rotate by cooperating with the gearbox 71, thereby performing reaming processing on the valve core.

[0038] In order to remove the debris generated during the reaming process, this application provides a waste discharge hole 100 at the bottom of the positioning cylinder 40, and the waste discharge hole 100 extends through the indexing plate 30. In addition, a waste collection box 90 is provided on the base 20 below the indexing plate 30. In specific implementation, the debris generated during reaming will fall from the inside of the valve core into the waste collection box 90 through the waste discharge hole 100.

[0039] As an example, the bidirectional drive component 51 of this application is one of a bidirectional drive cylinder or a bidirectional lead screw module. In actual use, if there are other types of bidirectional drive components 51 that can replace the above-mentioned bidirectional drive cylinder or bidirectional lead screw module, those skilled in the art can make appropriate selections.

[0040] In a preferred embodiment, the present application further provides V-shaped grooves 521 on the opposite side of the two clamping blocks 52 respectively. When the bidirectional drive assembly 51 drives the two clamping blocks 52 to move towards each other, the V-shaped grooves 521 of the two clamping blocks 52 will cooperate to clamp the valve core.

[0041] As an example, the lifting drive component 62 of this application is a one-way servo screw module. In actual use, if there are other types of lifting drive components 62 that can replace the above-mentioned one-way servo screw module, those skilled in the art can make appropriate selections.

[0042] In one specific embodiment, the gearbox 71 of this application is provided with a rotatable tool spindle 711 and a rotatable transmission shaft 712. The output shaft of the spindle motor 72 extends into the gearbox 71 and is equipped with a first gear 721. The tool spindle 711 is equipped with a second gear 7111 inside the gearbox 71. The transmission shaft 712 is equipped with a third gear 7121 that meshes with the first gear 721 and a fourth gear 7122 that connects to the second gear 7111. Driven by the spindle motor 72, the first gear 721 drives the transmission shaft 712 to rotate through the third gear 7121. The fourth gear 7122 on the transmission shaft 712 drives the tool spindle 711 to rotate through the second gear 7111, thereby causing the reaming tool 73 inside the tool spindle 711 to rotate and perform reaming machining on the valve core.

[0043] To ensure smooth lifting and lowering of the gearbox 71, this application also includes a counterweight system 80. The counterweight system 80 includes a counterweight block 81 slidably disposed in the support 61, two mounting seats 82 disposed on opposite sides above the lifting drive assembly 62, chain gears 83 rotatably disposed on opposite sides of the two mounting seats 82, and two guide chains 84 that mesh with the two chain gears 83 and connect the counterweight block 81 to the gearbox 71. When the lifting drive assembly drives the gearbox 71 to lift and lower, the two guide chains 84 will cooperate with the two chain gears 83 to make the counterweight block 81 lift and lower.
