Description

TECHNICAL FIELD

[0001] The utility model relates to a weighing butt joint jacking device applied to non-standard equipment belongs to transmission assembly test technical field. BACKGROUND

[0002] In the non-standard equipment of transmission assembly test production line, in order to realize the functions of oil extraction and weighing, a double-layer structure jacking device is usually arranged to lift the tray of transmission assembly at least twice. After lifting once, the tray is weighed by the weighing scale in the device. After lifting again, the tray is butted by other mechanisms in the non-standard equipment to perform oil extraction and oil addition operations.

[0003] The existing double-layer structure jacking device with similar functions usually uses two sets of motor + pulley + cam / cam lever structure to drive the lifting and lowering of the device. The disadvantage of this structure is that the size of the motor structure is large, occupying a large space, which cannot be installed in a compact space. Moreover, the cost of the motor is high, which does not meet the current requirement of cost reduction and efficiency improvement of enterprises.

[0004] In the weighing butt joint jacking device provided by the Chinese utility model patent with application number 202222243881.2, two motors are used to drive the lifting and lowering of the device. Each motor output end is provided with a pulley, which distributes power to the cam lever. An eccentric cam is installed on the cam lever, which lifts the weighing scale to the appropriate height with the rotation of the cam lever. The two-layer jacking structure is similar.

[0005] The existing technology has the following disadvantages or deficiencies:

[0006] 1. The structure size of the motor and pulley is large, which can only be arranged on the periphery of the device, thus greatly increasing the outer dimension of the device and occupying a larger space. Since the device is usually arranged under the roller line, there are other non-standard equipment around, and the installation space of the device is very compact.

[0007] 2. Since the device uses two sets of motors, the design cost is too high, which does not meet the requirement of cost reduction and efficiency improvement. CONTENT OF THE UTILITY MODEL

DETAILED DESCRIPTION

[0047] The specific embodiments of the present application are further described in detail below with reference to the accompanying drawings.

[0048] With reference to Figure 1 the weighing butt joint jacking device 130 of the utility model can realize the concentrated butt joint state and the weighing state of the pallets 110 on the roller line 120.

[0049] The automatic weighing butt joint jacking device applied to the non-standard equipment is combined by eight mechanisms, which are a weighing positioning mechanism 210 (the specific structure is shown in Figure 5 ), a concentrated butt joint positioning mechanism 220 (the specific structure is shown in Figure 6 ), a concentrated butt joint cylinder mechanism 230 (the specific structure is shown in Figure 7 ), a check valve mechanism 240 (the specific structure is shown in Figure 9 ), a blocking cylinder mechanism 250 (the specific structure is shown in Figure 8 ), a weighing butt joint mechanism 260 (the specific structure is shown in Figure 10 ), a first weighing support mechanism 270 (the specific structure is shown in Figure 11 ) and a second weighing support mechanism 280 (the specific structure is shown in Figure 12 ). The assembly and positional relationship of the eight mechanisms can be referred to Figure 2 , Figure 3 and Figure 4a and Figure 4b . Among them, Figure 4a the components are assembled on the upper part of Figure 4b , in order to facilitate understanding, the two are split in the drawing, and Figure 4a and Figure 4b the concentrated butt joint cylinder mechanism 230 appears repeatedly.

[0050] The components and assemblies of each mechanism are described in the related number references in the description of the drawings, and will not be introduced in detail in the specific embodiment.

[0051] With reference to Figure 5 , when the weighing positioning mechanism 210 works, the first mounting plate 2 is directly placed on the weighing scale 43, the weighing scale 43 is prevented from shifting in the working process through the weighing scale clamp plate 1, and the accurate butt joint (the pin hole of the centering pallet) is carried out with the pallet through the circular positioning pin 4 and the rhombic positioning pin 6, wherein the circular positioning pin 4 and the rhombic positioning pin 6 are positioned on the support plate 5 through the flange block 3. The base at the lower part of the support plate 5 is positioned on the first mounting plate 2 through the connecting plate 7, and the first mounting plate 2 as the base mounting plate of the support plate 5 and the circular positioning pin 4 and the rhombic positioning pin 6 thereon is fixed through the weighing scale clamp plate 1 and connected and fixed on the weighing scale 43 of the weighing butt joint mechanism 260.

[0052] With reference to Figure 6, the second mounting plate 8 of the positioning mechanism 220 is also provided with a center positioning pin 12 and a rhombus positioning pin 15 (both of which are positioned on the second mounting plate 8 through a support column 13) for accurately docking with the tray, and the second mounting plate 8 is also provided with a tray position detection component 81; refer to Figure 6 b, the main body part of the tray position detection component 81 is a support column 19, a bushing 20 is arranged in the hollow cavity of the support column 19, and the bushing 20 is sleeved on the shaft body of the position detection shaft 16; when the upper part of the position detection shaft 16 contacts the bottom of the tray, the position detection shaft 16 is pressed, and the spring 18 is compressed (the lower end of the spring 18 abuts against the bushing 20, and the upper end abuts against the shoulder of the head part of the position detection shaft, and the bushing 20 is fixed relative to the support column 19), the top surface of the position detection shaft 16 is pressed to be flush with the upper end surface of the flange block 17 (equivalent to that a counterbore is formed in the middle of the flange block 17 to accommodate the head part of the position detection shaft 16), and in the pressing process, the sensing block 22 arranged at the lower end of the shaft body of the position detection shaft 16 moves downward to a position that can be recognized by the proximity switch 23; the proximity switch 23 detects the position change of the position detection shaft 16. The proximity switch 23 is positioned at the lower surface of the second mounting plate 8 through a support 24. The distance between the sensing block 23 and the top part of the position detection shaft 16 can be adjusted appropriately to control or select the distance at which the sensing block and the proximity switch can interact when the position detection shaft 16 is pressed down, for example, the distance can be adjusted by arranging a pressing plate 21 at the lower part of the position detection shaft 16, the pressing plate 21 is fixed with the shaft body of the position detection shaft 16, and the upper surface of the pressing plate is attached to the lower end surface of the support column 19, and the purpose of the adjustment mentioned above can be achieved by adjusting the relative distance between the pressing plate 21 and the sensing block 22.

[0053] The middle part of the second mounting plate 8 is provided with an avoiding hole 82, the hole type of the avoiding hole 82 is adapted to the plate type of the support plate 5 of the weighing positioning mechanism 210, or at least the avoiding hole 82 does not block the stroke of the support plate 5 when the support plate 5 rises or falls. Therefore, in the actual application process of the device, the positioning pins (the circular positioning pin 4 and the rhombus positioning pin 6) on the support plate 5 and the positioning pins (the circular positioning pin 12 and the rhombus positioning pin 15) on the second mounting plate 8 selectively dock with the tray, and which one is selected depends on which one of the support plate 5 and the second mounting plate 8 is at the upper end position at that time. For example, when the weighing scale 43 is driven to rise, the first mounting plate 2 is driven to rise, and the support plate 5 continues to rise after passing through the avoiding hole 82 to a position higher than the second mounting plate 8 to complete the docking with the tray.

[0054] Refer to Figure 7 , Figure 4a and Figure 6The third floating joint 31 at the front end of the two centralized docking and lifting cylinders 32 is connected to the connecting screw 30. The other end of the connecting screw 30 is connected to the lower part of the second mounting plate 8 of the centralized docking and positioning mechanism. This means that the upper and lower ends of the connecting screw 30 are respectively connected to the second mounting plate 8 and the third floating joint 31, and are controlled by the centralized docking and lifting cylinders 32. Four guide rods 25 are provided on the upper part of the base plate 27 in four directions. The upper end of the guide rod 25 is fixedly connected to the second mounting plate 8 of the centralized docking and positioning mechanism 220. Each guide rod 25 is positioned and inserted (slidingly positioned) in a corresponding guide sleeve 26 (a bushing can be provided between the guide rod and the guide sleeve). The guide sleeve 26 is positioned on the upper surface of the base plate 27. Essentially, the connecting screw 30 provides the lifting power, while the four guide rods support and lift to achieve attitude control and stability of the second mounting plate 8 during lifting.

[0055] An HMI bracket 33 is also provided on the base plate 27. An HMI read / write head 34 is provided on the HMI bracket. The HMI read / write head 34, which is fixed at a fixed workstation, interacts with the code blocks on the tray to obtain relevant information about the test piece on the tray.

[0056] The blocking cylinder mechanism 250 and the check mechanism 240 are respectively installed on opposite sides of the base plate 27 of the centralized docking cylinder mechanism 230. The blocking cylinder mechanism 250 includes a cylinder mounting base 40 connected to the base plate 27. The check mechanism 240 is used to prevent the pallet from springing back (moving backward). The check device 41 is positioned on the base plate 27 via the check device base 42. The check device 41 is equivalent to a component controlling one-way passage, and it has a check member 410. A hinge shaft 412 is provided at the bottom of the inclined surface 411 of the check member 410. The pallet... Figure 9 When material arrives from the right side, the material acts on the inclined surface 411, and the component containing the inclined surface 411 rotates along the hinge axis after being compressed until the inclined surface 411 is in a horizontal state. After the material passes from right to left, the pressure on the inclined surface disappears, and the pressure on the internal spring also disappears. The spring pushes the check member 410 to reset, that is, the inclined surface 411 returns from horizontal to the inclined surface state; while when the pallet moves from... Figure 9 When material arrives from the left side, the pallet cannot act directly on the inclined plane, but acts on the vertical end face of the left side of the component. Therefore, the component will not rotate with its hinge shaft 412, thus achieving the function of one-way backstop.

[0057] When the weighing and lifting device 130 (i.e., the device of this utility model) needs to weigh (see...), Figure 2The blocking cylinder 37 of the blocking cylinder mechanism 250 is extended to stop the tray, and the check valve prevents the tray from returning; then, the weighing docking cylinder 50 at the lower part of the weighing scale 43 is extended, and the weighing scale 43, the weighing positioning mechanism 210 and the like are lifted together. During the lifting process, the four sets of assemblies composed of the guide sleeves 46, the guide rods 47 and the bushings 48 (see Figure 10 ) realize stable lifting of the device and balance the overturning force generated by the eccentricity of the tray. The circular positioning pin 4 and the rhombic positioning pin 6 realize the docking of the device and the tray. When the weighing docking cylinder 50 is completely extended, the first pushing cylinder 61 and the second pushing cylinder 68 are simultaneously extended in the horizontal direction, and then the first floating joint 60 and the second floating joint 67 at the front end of the pushing cylinder push the first support slider 59 and the second support slider 66 forward to be just below the first support block 52 and the second support block 53 at the lower part of the weighing scale 43. The first support slider 59 can slide in a space enclosed by the first support sliding platform 58 (for example, in a limiting groove). The second support slider 66 can slide in a space enclosed by the second support sliding platform 65 (for example, in a limiting groove). Finally, the weighing docking cylinder 50 is retracted, and the two sets of support blocks fall onto the two sets of support sliders, forming stable three-point support, as shown in Figures 11-13 The first support slider 59 of the first weighing support mechanism 270 provides a support surface 591 for supporting the first support block 52 and provides a support point. The second support slider 66 of the second weighing support mechanism 280 provides two support surfaces 661 and 662 (which are actually in the same plane) for supporting the second support block 53 and provides two support points. A total of three points are supported, forming a stable support structure. This structure realizes accurate measurement of the weighing scale 43 and avoids deviation of the weighing measurement result caused by unstable compressed air. After the weighing is completed, the code block of the tray is exchanged with the HMI read-write head 34 to realize information exchange, and finally the components are retracted, and the device returns to the initial state.

[0058] When the weighing docking and jacking device needs to place the tray in a dockable state (for example, as shown in Figure 3In the indicated state, the blocking cylinder 37 extends to stop the tray, and the check valve 41 prevents the tray from retracting. Subsequently, the centralized docking lifting cylinders 32 located on both sides of the device extend simultaneously, raising the centralized docking positioning mechanism 220 together. During the rising process, the guide rod 25 and guide sleeve 26 achieve precise raising of the device and withstand the lateral overturning force generated by the tray's eccentricity. Information exchange is achieved through interaction between the HMI reader / writer 34 and the code blocks on the tray. When the device contacts the tray, the circular positioning pin 12 and the diamond positioning pin 15 dock with the tray to achieve precise positioning of the tray; two sets of symmetrically distributed position detection shafts 16 and proximity switches 23 detect whether the tray is docked in place, ensuring successful docking on the first attempt. Furthermore, the cylinders can be precisely limited by setting corresponding adjustment mechanisms to ensure the consistency of the tray docking height. After docking, the HMI reader / writer 34 interacts with the code blocks on the tray to achieve information exchange, and finally, all components retract, and the device returns to its initial state.

[0059] The second mounting plate 8 has a contour notch in the middle (i.e., the avoidance hole 82 mentioned above), which allows the support plate 5 to pass freely. Therefore, the two actions of weighing and putting the tray into a dockable state are independent of each other, and the order and number of actions can be adjusted at will.

[0060] The automatic weighing docking and lifting device for non-standard equipment provided by this utility model has a cleverly designed weighing support mechanism that ensures both the compact structure of the device (mainly achieved by the support blocks provided by the first and second push cylinders with lateral drive) and the accuracy and stability of weighing. The internal structural arrangement of the device allows for flexible operation with no predetermined sequence between the two sets of actions.
