Description

[Technical field]

[0001] The invention relates to tooling equipment and a processing method, and in particular to a clamp spring assembly equipment and a clamp spring assembly method. [Background technology]

[0002] The existing automated spring assembly equipment includes a spring preparation area and a spring assembly area. After the clamping jaws obtain the spring in the spring preparation area, they carry the spring to the spring assembly area and extend into the workpiece to be assembled with the spring. The clamping jaws open or contract so that the spring pops out from the clamping jaws and directly enters the workpiece to be assembled with the spring. That is, the spring is in a compressed or stretched elastic state from the time the clamping jaws obtain the spring to the time the spring is detached from the clamping jaws. In this assembly method, when the spring is assembled into the workpiece, the spring is clamped or stretched by the action of the clamping jaws, and the spring is in a compressed or stretched state. When the spring pops out from the clamping jaws, the spring pops out at an inaccurate position due to its own elastic force and the action of the clamping jaws, resulting in assembly failure, or the inaccurate assembly position of the spring and the workpiece to be assembled with the spring causes the spring to collide with the workpiece, causing damage to the parts. In order to reduce the collision between the retaining spring and the workpiece, there is a retaining spring clamping device which is to set up a press and fix a sleeve on the press. The retaining spring is first placed in the sleeve and then the retaining spring is pushed into the workpiece by the pressure rod of the press. However, the sleeve and the press of this clamping device need to be fixed, and generally can only be assembled manually, which is difficult to achieve through automation. [Summary of the invention]

[0031] It should be noted that: "the first workbench 2 is installed on the machine 1" can be understood as that the first workbench 2 is directly installed on the machine 1; it can also be understood as that the first workbench 2 is indirectly installed on the machine 1, that is, the first workbench 2 is installed on other components connected to the machine 1; the first holding device and the second holding device can be a manipulator with a gripper or a robot.

[0032] In one embodiment, reference Figure 1-Figure 5The first adjustment assembly 8 at least includes a first main body 81, a first movable part 82 and a first driving part 83. The first main body 81 is fixed to the machine table 1. The first driving part 83 can drive the first movable part 82 to move relative to the first main body 81. The first holding device 4 is fixed to the first movable part 82. Specifically, the first main body 81 and the second movable part are plate-shaped structures.

The first driving part The driving shaft corresponding to the movable part 83 is rotationally connected to the first movable part 82.

More specifically, the moving direction between the first movable part 82 and the first main body part 81 is a vertical direction of the Z axis of the retaining spring assembly equipment, for example, the X direction, that is, the first movable part 82 drives the first holding device 4 to move in the X direction of the retaining spring assembly equipment, the first holding device obtains the retaining spring, and the first movable part 82 drives the first holding device 4 to move along the X axis of the retaining spring assembly equipment to the first workbench 2 above the Z axis of the retaining spring assembly equipment, and places the retaining spring on the sleeve 7 located on the first workbench 2.

[0033] As other embodiments, the first driving part 83 may be a linear motor or a cylinder, which drives the first moving part 82 and the first main body part 81 to move relative to each other, which will not be elaborated here.

Specifically, the first holding device 4 is indirectly fixed to the first moving part 82. The spring assembly device includes a second adjustment component 012. At least a portion of the second adjustment component 012 is located at the first moving part 82. At least a portion of the first holding device 4 is located at the second adjustment component 012. The second adjustment component 012 can adjust the first holding device 4 to move along the Z-axis direction or the reverse direction of the spring assembly device. That is, when the first holding device 4 is located above the sleeve 7 corresponding to the first workbench 2 along the Z-axis of the spring assembly device, the second adjustment component 012 adjusts the first holding device 4 to move close to the sleeve along the Z-axis direction of the spring assembly device. 7. When the first holding device 4 moves to the corresponding position, the first holding device 4 places the retaining spring 9 on the sleeve 7 located on the first workbench 2; after the first holding device 4 places the retaining spring on the sleeve 7 located on the first workbench 2, the second adjustment component 012 adjusts the first holding device 4 to move the first holding device 4 away from the sleeve 7 along the opposite direction of the Z-axis of the retaining spring assembly equipment. Specifically, the second adjustment component 012 can be a cylinder, and the second adjustment component 012 is fixed to the first moving part 82. The structural space occupied by the cylinder is smaller than that of other power mechanisms; of course, the second adjustment component 012 can also be a mobile module, which is not repeated here.

[0035] In one embodiment, reference Figure 1-Figure 5 The sleeve 7 has a through hole 73, which includes a reducing section 731 and a first section 732. The reducing section 731 and the first section 732 are connected, and the diameter of the reducing section 731 decreases in the direction toward the first section 732. The maximum inner diameter corresponding to the reducing section 731 is larger than the outer diameter of the retaining spring in the natural state, and the minimum diameter corresponding to the reducing section 731 is smaller than the outer diameter of the retaining spring in the natural state.

[0036] Specifically, the sleeve 7 has a sleeve wall portion 733, which is located on the peripheral side of the through hole 73. The sleeve wall portion 733 has a first end and a second end along the extension direction of the through hole 73. The first end is an end of the sleeve wall portion 733 close to the first section 732, and the second end is an end close to the reducing section 731. On the first workbench 2, the second end is located above the first end along the direction of gravity.

[0037] Such processing equipment, by making the maximum diameter of the reducing section 731 larger than the outer diameter of the retaining spring in its natural state, and the minimum diameter of the reducing section 731 smaller than the outer diameter of the retaining spring in its natural state, that is, at least part of the sleeve wall portion 733 corresponding to the reducing section 731 can limit the retaining spring.

[0038] In one embodiment, reference Figure 1-Figure 5The retaining spring assembly equipment includes a second clamping device 011, which is located above the first workbench 2 along the Z-axis of the retaining spring assembly equipment. Specifically, the second clamping device 011 is a press; the second clamping device 011 can move in the Z-axis direction of the retaining spring assembly equipment. Specifically, the outer dimensions of the pressure head corresponding to the second clamping device 011 are smaller than the diameter corresponding to the first section 732, and the diameter corresponding to the first section 732 is smaller than the diameter of the retaining spring in a natural state; the first workbench 2, the second clamping device 011 can press the retaining spring into the sleeve, so that the retaining spring is in a compressed state in the sleeve, and the sleeve limits the retaining spring to prevent the retaining spring from falling off from the sleeve during the conveying process. More specifically, the second clamping device 011 can press the retaining spring from the reducing section 731 into the first section 732.

[0039] Such a retaining spring assembly equipment is located above the first workbench 2 along the Z-axis of the retaining spring assembly equipment through the second clamping device 011. The outer dimensions of the pressure head corresponding to the second clamping device 011 are smaller than the diameter corresponding to the first section 732. The second clamping device 011 can press the retaining spring from the reducing section 731 into the first section 732. The diameter corresponding to the first section 732 is smaller than the diameter of the retaining spring in the natural state, that is, the first section 732 limits the retaining spring, and the retaining spring is in a clamped state, thereby preventing the retaining spring from falling off from the sleeve 7 when the second holding device 5 obtains the sleeve 7 and places the sleeve 7 on the workpiece 010 to be assembled with the retaining spring located on the second workbench 3.

[0040] It should be noted that the second clamping device 011 is located above the first workbench 2 along the Z-axis of the retaining spring assembly equipment. It can be understood that in the direction along the Z-axis of the retaining spring assembly equipment, the second clamping device 011 and the first workbench 2 have different heights, and in the vertical direction along the Z-axis of the retaining spring assembly equipment, for example, in the direction of the X-axis of the retaining spring assembly equipment, the second clamping device 011 and the first workbench 2 correspond in position. It is also possible that after at least one of the second clamping device 011 and the first workbench 2 is positioned appropriately, the second clamping device 011 and the first workbench 2 correspond in position to each other in the X-axis of the retaining spring assembly equipment.

[0041] Specifically, the second clamping device 011 can be fixed to the first movable part 82, that is, the first adjustment component 8 can control the second clamping device 011 to move in the vertical direction of the Z-axis of the retaining spring assembly equipment, such as the X-axis movement of the retaining spring assembly equipment, so that the pressure head of the second clamping device 011 corresponds to the position of the sleeve 7 located on the first workbench 2.

[0042] In one embodiment, reference Figure 1-Figure 5The machine 1 has a first position 001 and a second position 002, the first position is closer to the first holding device relative to the second position, and the second position is farther away from the first holding device relative to the first position, the spring assembly equipment has a second driving part 013, the second driving part is installed on the machine 1, and the second driving part can drive the first workbench 2 to move between the first position 001 and the second position 002 of the machine 1; the second driving part can be a moving module, a linear motor or a cylinder. In the present embodiment, the second driving part is a linear motor or a cylinder, and the second driving part can occupy a smaller mechanism space; and the second driving part can drive the first workbench 2 to move between the first position 001 and the second position 002 of the machine 1, avoiding interference between the first holding device 4, the second holding device 5 and the first adjustment component 8 during operation, making room for the first holding device 4, the second holding device 5 and the first adjustment component 8, and also reducing the waiting time of the actuator due to the narrow space, making the working rhythm more compact.

[0043] It should be noted that: "actuator" should be understood as all parts that perform actions during the spring assembly process, including but not limited to the first holding device 4, the second holding device 5 and the first adjustment assembly 8, and may also be other structures in other implementations; "the second drive unit is installed on the machine 1" can be understood as the second drive unit 013 is directly installed on the machine 1; it can also be understood as the second drive unit 013 is indirectly installed on the machine 1, that is, the second drive unit 013 is installed on other components connected to the machine 1.

[0045] The second holding device 5 moves between at least three areas, namely, the first area and the second area of ​​the first workbench 2 corresponding to the second position 002 of the first workbench 2, and the second workbench. The second holding device is a manipulator; more specifically, the first holding device 4 can alternately place the retaining spring on the first sleeve 71 and the second sleeve 72, and the second holding device 5 can alternately place the first sleeve 71 and the second sleeve 72 equipped with the retaining spring on the workpiece 010 to be assembled with the retaining spring. If there is only one sleeve 7, after the first clamping device 6 presses the retaining spring in the sleeve 7 into the workpiece 010 to be assembled with the retaining spring, the second holding device 5 obtains the sleeve 7 with the retaining spring pressed out on the second workbench 3. , and after placing the sleeve 7 on the first workbench 2, a waiting time needs to be reserved for the first holding device 4 to obtain the retaining spring and place the retaining spring on the sleeve 7 located on the first workbench 2. If there are two sleeves, the second holding device 5 obtains a sleeve equipped with a retaining spring on the first workbench 2, and places the sleeve on the workpiece 010 to be assembled with the retaining spring located on the second workbench 3. The first clamping device 6 presses the retaining spring into the workpiece 010 to be assembled with the retaining spring. The second holding device 5 obtains the sleeve after the retaining spring is pressed out from the second workbench 3, and places the sleeve on the first workbench 2. During this process, the first holding device 4 can synchronously obtain the retaining spring and place the retaining spring in the other sleeve, which makes the rhythm more compact and improves the assembly efficiency.

[0046] It should be noted that: the first workbench 2 is installed on the positioning frame 12, which can be understood as the first workbench 2 is directly installed on the positioning frame 12; it can also be understood that the first workbench 2 is indirectly installed on the positioning frame 12, that is, the first workbench 2 is installed on other components connected to the positioning frame 12.

[0047] It should be noted that the first adjustment component controls the moving direction of the first holding device and / or the second clamping device, corresponding to the first area and the second area, to ensure that the first holding device and / or the second clamping device can move to above the first area and / or the second area. The second adjustment component 012 adjusts the first holding device 4 along the Z-axis direction of the retaining spring assembly device to approach the first area and / or the second area, and performs corresponding actions; the second clamping device can approach the first area and / or the second area along the Z-axis direction of the retaining spring assembly device, and perform corresponding actions.
