DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] Reference Figure 1-Figure 7 The utility model discloses a clamping and fixing mechanism for machining a solenoid valve body, comprising: a pair of clamping assemblies 2, arranged on both sides of a valve body 1; the clamping assembly 2 comprises a clamping plate 23, on which a plurality of telescopic columns 24 are arranged, the telescopic columns 24 are arranged close to the valve body 1 as clamping ends, and the clamping ends clamp the valve body 1; the telescopic columns 24 are arranged in a locking state and an active state in the clamping plate 23, in the active state, the telescopic columns 24 are telescoped in the clamping plate 23, in the locking state, the telescopic columns 24 are arranged along the outer wheel of the valve body 1 The outer contour of the valve body 1 is relatively fixed with the clamping plate 23; the placing component 3 is arranged on the bottom surface of the valve body 1 and contacts with the bottom surface of the valve body 1; the placing component 3 includes a lifting box 34, and a plurality of lifting heads 31 are arranged in the lifting box 34, and the plurality of lifting heads 31 are supported along the outer contour of the valve body 1, and the plurality of lifting heads 31 are provided with a fixed state and a telescopic state. In the telescopic state, the plurality of lifting heads 31 are telescoped in the lifting box 34 along the outer contour of the valve body 1, and in the fixed state, the plurality of lifting heads 31 support and fix the valve body 1 along the outer contour of the valve body 1.

[0037] The clamping mechanism can fit the bottom of the valve body 1 well by placing the several lifting heads 31 on the assembly 3, so that the valve body 1 is not affected by its own shape when being clamped and fixed, thereby making the valve body 1 itself easier to be clamped and fixed; the several telescopic columns 24 arranged on the clamping plate 23 in the clamping assembly 2 can fit the side of the valve body 1 well, thereby clamping and fixing the valve body 1, and at the same time, the several telescopic columns 24 are not restricted by the contour of the valve body 1, and can fit solenoid valve bodies of various models and shapes, so that when the solenoid valve body is processed on the same machine tool, the time required to replace the fixture due to different valve body models is saved, thereby improving the processing efficiency of the solenoid valve body.

[0038] A further optimized solution is that the clamping assembly 2 also includes: a clamping column 22, fixed on the side of the clamping plate 23 away from the valve body 1, and a hydraulic box 21 is fixed to one end of the clamping column 22; an oil chamber 26, arranged in the hydraulic box 21, an oil main pipe 25 is opened in the clamping column 22, and the clamping plate 23 is provided with telescopic chambers with the same number as the telescopic columns 24, the telescopic chambers are connected to the oil main pipe 25, and the oil main pipe 25 is also connected to the oil chamber 26, and the oil chamber 26 is connected to an external machine tool and controlled by the external machine tool; a clamping spring 27, arranged in the telescopic chamber, one end of which is fixed to the telescopic column 24, and the other end is fixed in the oil main pipe 25.

[0039] Among them, refer to Figure 6 and Figure 7 The end of the telescopic column 24 close to the valve body 1 is rotated and connected to the clamping head 28, and two contact points are set on the clamping head 28. A torsion spring 29 is fixed between the clamping head 28 and the telescopic column 24. When clamping, the clamping head 28 contacts the side of the valve body 1. At this time, the clamping head 28 twists as it contacts the side of the valve body 1 until the two contact points fit better with the side of the valve body 1.

[0040] Specifically, when the telescopic column 24 is in an active state in the clamping plate 23, multiple telescopic columns 24 gradually fit against the side of the valve body 1. At this time, the side of the valve body 1 presses the telescopic column 24, so that the telescopic column 24 retracts into the clamping plate 23, and the telescopic column 24 compresses the spring. When the telescopic column 24 is in a locked state, the external machine tool controls the oil level in the oil chamber 26 in the hydraulic box 21, so that the oil level in the oil main pipe 25 and the telescopic chamber is fixed, so that after the telescopic column 24 is completely fitted against the side of the valve body 1, each telescopic column 24 is in a fixed state under the combined pressure of the oil pressure and the external atmospheric pressure, thereby causing the clamping plate 23 to clamp the valve body 1.

[0041] A further optimized solution is that the placement component 3 also includes: a top plate 36, fixed at the open end of the jacking box 34, the top plate 36 is provided with the same number of through holes as the jacking head 31, and the jacking head 31 passes through the through holes; a liquid supply chamber 35, arranged at the bottom of the jacking box 34, filled with hydraulic oil, and the liquid supply chamber 35 is also connected to an external machine tool and controlled by the external machine tool; a hydraulic pipe 32, connected to the liquid supply chamber 35, filled with hydraulic oil, and the jacking head 31 retracts and contracts in the hydraulic pipe 32; a jacking spring 33, arranged in the hydraulic pipe 32, one end of the jacking spring 33 is fixed to the jacking head 31, and the other end is fixed to the liquid supply chamber 35.

[0042] Specifically, when the valve body 1 is placed on the multiple lifting heads 31 of the lifting box 34, the multiple lifting heads 31 are pressed under the weight of the valve body 1, so that the multiple lifting heads 31 compress the lifting springs 33, so that the multiple lifting heads 31 after the valve body 1 is placed retract to different lengths along the bottom surface contour of the valve body 1; at this time, the lifting heads 31 are in a telescopic state, and the multiple lifting heads 31 gradually fit the bottom surface contour of the valve body 1. When the placement component 3 as a whole completely fits the bottom surface of the valve body 1, the placement component 3 is directly put into a fixed state through the control panel of the external machine tool. At this time, the external machine tool controls the amount of oil in the liquid supply chamber 35 and the hydraulic pipe 32, so that the lifting heads 31 are in a fixed state under the matching pressure of the oil pressure and the external atmospheric pressure, and after the placement component 3 as a whole completely fits the bottom surface of the valve body 1, each lifting head 31 is fixed, thereby supporting the valve body 1 so that it does not deflect easily.

[0043] According to a further optimized solution, the two clamping assemblies 2 are also transmission-connected to a driving assembly 4 , which is disposed on a vertical support plate 6 , and controls the movement of the two clamping assemblies 2 .

[0044] A further optimized solution is that the drive assembly 4 includes: two moving blocks 41, which are respectively fixed on the two hydraulic boxes 21, and a sliding groove 61 is opened on the vertical support plate 6, and the moving block 41 is slidably connected in the sliding groove 61; a driving motor 43, which is fixed to the vertical support plate 6 through a fixed plate 42, and a lead screw 44 is fixed to the output end of the driving motor 43, and the lead screw 44 is provided with threads with opposite rotation directions, and the two moving blocks 41 are respectively threadedly connected to the two ends of different threads on the lead screw 44.

[0045] Specifically, because the threads at both ends of the lead screw 44 are opposite, when the drive motor 43 controls the lead screw 44 to rotate, the two moving blocks 41 on the lead screw 44 can move in opposite directions. When the valve body 1 needs to be clamped, the drive motor 43 is directly controlled to rotate. At this time, the two moving blocks 41 on the lead screw 44 move toward the valve body 1, thereby allowing the two clamping plates 23 to clamp the valve body 1.

[0046] According to a further optimized solution, the vertical support plate 6 is fixed to one end of the horizontal bottom plate 7, and the horizontal bottom plate 7 is provided with a jacking hole, and the jacking box 34 moves up and down along the jacking hole.

[0047] To further optimize the solution, a lifting cylinder 5 is further provided on the side of the horizontal bottom plate 7 away from the valve body 1 , and the lifting cylinder 5 is fixed on the side of the horizontal bottom plate 7 away from the valve body 1 through a cylinder fixing frame 9 , and the movable end of the lifting cylinder 5 is fixed to the lifting box 34 .

[0048] Among them, after the valve body 1 is placed on the lifting head 31, the height of the lifting box 34 can be controlled according to the actual volume and size of the valve body 1, so that the height of the valve body 1 can be more easily clamped and fixed by the two clamping components 2; and the lifting cylinder 5 can be directly connected to an external machine tool, and the extension amount of the movable end of the lifting cylinder 5 can be directly controlled through the control panel on the machine tool, thereby controlling the lifting height of the lifting box 34.

[0049] According to a further optimized solution, a plurality of legs 8 are fixed to the horizontal base plate 7 , and the horizontal base plate 7 is fixed to the external machine tool through the plurality of legs 8 .

[0050] Working process: The valve body 1 is placed on the multiple lifting heads 31 of the lifting box 34. The multiple lifting heads 31 are pressed under the weight of the valve body 1, so that the multiple lifting heads 31 compress the lifting springs 33, so that the multiple lifting heads 31 after the valve body 1 is placed retract to different lengths along the bottom surface contour of the valve body 1. At this time, the multiple lifting heads 31 fit the bottom surface contour of the valve body 1, so that the placement component 3 as a whole completely fits the bottom surface of the valve body 1. At this time, the placement component 3 can be directly put into a fixed state through the control panel of the external machine tool, so that the placement component 3 as a whole completely fits the valve body 1. After the placing assembly 3 enters the fixed state, the driving motor 43 is started to make the two moving blocks 41 approach the valve body 1, so that the multiple telescopic columns 24 on the two clamping plates 23 are in contact with the side of the valve body 1. After the multiple telescopic columns 24 on both sides of the valve body 1 are completely in contact with the side of the valve body 1, the clamping assembly 2 is directly put into the locking state through the control panel of the external machine tool, so that the multiple telescopic columns 24 on both sides lock the valve body 1. After locking, the valve body 1 can be processed.
