Description
Technical Field
[0001] This application relates to the field of high-speed rail component manufacturing technology, specifically to an automated processing and positioning device for valve bodies. Background Technology
[0002] With the continuous improvement of my country's railway transport capacity and mileage, the demand for high-speed trains is increasing year by year. In order to meet the construction needs of high-speed trains and complete more production tasks, it is necessary not only to improve processing efficiency and save processing time, but also to ensure the stability and consistency of each batch of parts processing, so as to produce high-quality, high-standard train parts.
[0003] In the manufacturing process of height valves, the traditional machining and clamping method is: the worker manually presses down on the workpiece and then manually tightens the OK fixture to clamp the workpiece. The disadvantage of this clamping method is that each clamping is greatly influenced by human factors. Due to the difference in the direction and force of manual pressing, slight deviations in the clamping position are caused, resulting in low consistency of the finished product's machining dimensions. Utility Model Content

[0040] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the embodiments and accompanying drawings. The illustrative embodiments and descriptions of this application are only for explaining this application and are not intended to limit this application.
[0041] like Figure 1 , Figure 2 and Figure 4 As shown in the figure, this application provides an automated valve body processing assembly positioning device, which includes a base 1, a first clamping mechanism, a second clamping mechanism, a pressing mechanism, and a controller. The base 1 has a limiting groove 2, which is used to fit with a portion of the workpiece to be clamped, so that the base 1 can limit the workpiece to be clamped in multiple directions through the limiting groove 2. The first clamping mechanism is connected to the base 1 and is used to press the workpiece to be clamped onto the base 1 in a first direction. The second clamping mechanism is connected to the base 1, and the first clamping mechanism is used to press the workpiece to be clamped onto the base 1 in a first direction. The two clamping mechanisms are used to clamp the workpiece to be clamped onto the base 1 in the second direction. Normally, the first direction and the second direction do not coincide. Of course, in other embodiments, it is not excluded that the first direction and the second direction coincide, that is, the first clamping mechanism and the second clamping mechanism move towards each other or away from each other. The abutting mechanism is connected to the base 1 and has an abutting part located in the limiting groove 2. The abutting mechanism is used to press the workpiece to be clamped against the groove wall of the limiting groove 2 through the abutting part. The first clamping mechanism, the second clamping mechanism and the abutting mechanism are respectively connected to the controller for controlled operation.
[0042] During operation, the workpiece to be clamped is placed on the base 1 by the robot arm of the previous station. Part of the structure of the workpiece to be clamped is located in the limiting groove 2, so that the groove wall of the limiting groove 2 can limit the workpiece to be clamped in at least one direction. By controlling the action of the first clamping mechanism, the first clamping mechanism can clamp the workpiece to be clamped in the first direction, which can be perpendicular to the bottom of the limiting groove 2. At the same time, the action of the second clamping mechanism is controlled so that the second clamping mechanism can clamp the workpiece to be clamped in the second direction, which can be orthogonal to the first direction. The action of the abutting mechanism is controlled to abut the part of the workpiece to be clamped located in the limiting groove 2 against the groove wall of the limiting groove 2, where the action direction of the abutting mechanism is orthogonal to the second direction. Thus, the workpiece to be clamped is limited in three mutually orthogonal directions, thereby ensuring that the position of the workpiece to be clamped on the base 1 is stable, and then the processing / assembly of the workpiece to be clamped can be performed.
[0043] The valve body automated processing and positioning device provided in this application embodiment can press the valve body onto the base 1 in two directions through the first pressing mechanism and the second pressing mechanism on the base 1, and press the valve body against the groove wall of the limiting groove 2 through the abutting mechanism, thereby achieving accurate positioning of the valve body on the base 1. Compared with traditional manual clamping, the first pressing mechanism, the second pressing mechanism and the abutting mechanism in this application are motion mechanisms, and all of them can be controlled to achieve automatic clamping of the valve body. With the help of the robot arm in other stations, the automatic clamping of the valve body can be achieved. By controlling the motion parameters of the first pressing mechanism, the second pressing mechanism and the abutting mechanism, the clamping force can be controlled, thereby ensuring the consistency of the clamping force each time, ensuring the positional accuracy of the valve body on the base 1, and thus ensuring that the finished product processing dimensions have good consistency.
[0044] In this embodiment, the first clamping mechanism, the second clamping mechanism, and the abutting mechanism can all be equipped with force sensors. The force sensors are used to collect the reaction force fed back by the workpiece to be clamped during clamping / abutting, thereby realizing the adaptive adjustment of the clamping force / abutting force of the first clamping mechanism, the second clamping mechanism, and the abutting mechanism. This prevents the second clamping mechanism and / or the abutting mechanism from being unable to correct the position of the workpiece to be clamped by applying force when, for example, the first clamping mechanism first clamps the workpiece to be clamped in a non-predetermined position with a large clamping force.
[0045] In this embodiment of the application, the base 1 is a rectangular plate structure. The limiting groove 2 on the base 1 extends through the base 1 along the width direction of the base 1, and the width of the middle part of the limiting groove 2 is greater than the width of the two ends in the width direction of the base 1.
[0046] In some optional embodiments, the first clamping mechanism includes a first driving source and a first clamping arm 3; the first driving source is connected to the base 1; the first clamping arm 3 is connected to the first driving source to rotate under the drive of the first driving source and clamp the workpiece to be clamped onto the base 1, that is, the first driving source can drive the first clamping arm 3 to rotate, and can also drive the first clamping arm 3 to move linearly so that the first clamping arm 3 moves closer to or further away from the workpiece to be clamped in the direction perpendicular to the bottom of the limiting groove 2.
[0047] In some alternative embodiments, the first drive source is configured as a rotary telescopic hydraulic cylinder, wherein one end of the first clamping arm 3 is connected to the moving end of the rotary telescopic hydraulic cylinder.
[0048] In this embodiment, the rotary telescopic hydraulic cylinder is existing technology. While driving the first clamping arm 3 to move linearly, it can also drive the first clamping arm 3 to rotate, thus realizing the automatic clamping of the workpiece to be clamped by the first clamping mechanism.
[0049] In some alternative embodiments, a first elastic plunger 4 is connected to the first clamping arm 3, the first elastic plunger 4 being used to press against the workpiece to be clamped.
[0050] In this embodiment, the first elastic plunger 4 provides a certain degree of flexible buffering to prevent damage to the surface of the workpiece to be clamped during the clamping process of the first clamping mechanism, while allowing the first clamping mechanism to apply a greater clamping force.
[0051] In some optional embodiments, the second clamping mechanism includes a second drive source and a second clamping arm 5; the second drive source is connected to the base 1; the second clamping arm 5 is connected to the second drive source to rotate under the drive of the second drive source and clamp the workpiece to be clamped onto the base 1, that is, the second drive source can both drive the second clamping arm 5 to rotate and drive the second clamping arm 5 to move linearly so that the second clamping arm 5 moves closer to or away from the workpiece to be clamped in a direction perpendicular to the bottom of the limiting groove 2. In other embodiments, the second clamping mechanism may also include a telescopic cylinder 11, a clamping rod 10, and an auxiliary clamping block 7. The clamping rod 10 movably passes through the base 1, the telescopic cylinder 11 is connected to the base 1, the clamping rod 10 is connected to the moving end of the telescopic cylinder 11 to move axially under the drive of the telescopic cylinder 11, the auxiliary clamping block 7 is connected to the base 1, and the auxiliary clamping block 7 and the free end of the clamping rod 10 are spaced apart to form a clamping gap between them, such as Figure 3 As shown, this clamping structure is suitable for situations where there are specific requirements for the clamping position of the valve body. This clamping structure can form a combined tooling with the clamping structure composed of the aforementioned second drive source and the second clamping arm 5, which means that the entire tooling includes two processes.
[0052] In some alternative embodiments, the second drive source is configured as a rotary telescopic hydraulic cylinder, wherein one end of the second clamping arm 5 is connected to the moving end of the rotary telescopic hydraulic cylinder.
[0053] In some alternative embodiments, a second elastic plunger 6 is connected to the second clamping arm 5, the second elastic plunger 6 being used to press against the workpiece to be clamped.
[0054] In this embodiment, the rotary telescopic hydraulic cylinder is a prior art technology. While driving the second clamping arm 5 to move linearly, it can also drive the second clamping arm 5 to rotate, thus realizing the automatic clamping of the workpiece to be clamped by the second clamping mechanism.
[0055] In some optional embodiments, the clamping mechanism includes a pressure block 7 and a clamping drive source; the pressure block 7 is located in the limiting groove 2 and is slidably connected to the base 1; the clamping drive source is connected to the base 1 and to the pressure block 7 to drive the pressure block 7 to move in the limiting groove 2, wherein the movement direction of the pressure block 7 is parallel to the bottom of the limiting groove 2, so that when the pressure block 7 moves, it can clamp the workpiece to be clamped against the groove wall of the limiting groove 2.
[0056] In some optional embodiments, the clamping drive source includes a clamping hydraulic cylinder 8 and a drive wedge 9; the clamping hydraulic cylinder 8 is connected to the base 1; the drive wedge 9 is connected to the clamping hydraulic cylinder 8, and the drive wedge 9 has a first drive wedge surface; wherein, the pressure block 7 has a second drive wedge surface that fits against the first drive wedge surface. When the drive wedge 9 is driven by the clamping drive source, the contact area between the first drive wedge surface and the second drive wedge surface can be changed, thereby causing the pressure block 7 to move. The pressure block 7 is elastically slidably connected to the base 1, so that when the drive wedge 9 removes the driving force on the pressure block 7, the pressure block 7 can automatically reset. Specifically, the pressure block 7 can be movably inserted into the base 1 through a guide rod. A helical spring and an end cap are sleeved on the guide rod. The end cap is connected to the base 1. The end of the guide shaft is provided with a limiting shoulder, so that the end cap can axially limit the guide shaft and prevent the guide shaft from disengaging from the base 1.
[0057] In some optional embodiments, the base 1 has multiple mounting slots, and the first pressing mechanism, the second pressing mechanism, and the abutting mechanism are respectively installed in the mounting slots. For example, the first driving source, the second driving source, and the abutting driving source mentioned above can all be installed in the mounting slots. This arrangement can make the structure more compact and reduce the overall space occupied by the device.
