Description

Technical Field

[0001] The present invention relates to the technical field of sensor production, in particular to a sheath installation device and a pre-pressing device thereof. Background Art

[0002] The connecting wires of sensors are mainly used to transmit signals and provide power. In order to protect the connecting wires, sheaths are often installed at the parts of the connecting wires that are prone to bending and wear to increase the service life of the sensors.

[0003] In order to ensure that the sheath is tightly pressed on the connecting wire, the inner hole diameter of the sheath is designed to be smaller than the outer diameter of the connecting wire, so that the sheath and the connecting wire are interference fit. Since the materials in contact with the sheath and the connecting wire are soft materials such as rubber, the two cannot be directly positioned and clamped. The traditional way of installing the sheath is to prepare a hollow metal adapter tube, manually apply lubricant and clamp the sheath on the adapter tube, pass the connecting wire through the inner hole of the adapter tube, move the sheath to the position where the connecting wire is to be clamped, and use calipers to remove the sheath from the adapter tube so that the sheath is fixed on the connecting wire. After cutting, the semi-finished connecting wire is obtained for subsequent wiring installation.

[0004] However, in reality, the above installation method is adopted. Because the outer diameter of the adapter is much larger than the outer diameter of the connecting line, it is still extremely difficult to manually install the sheath on the adapter even with lubricating oil, and the labor-consuming time is also high. At the same time, the sheath needs to be positioned and marked on the connecting line in advance before it is clamped on the connecting line. The manual marking error is large, and the relative position of the sheath needs to be manually adjusted again after installation, which is time-consuming, labor-intensive and has low production efficiency.

[0027] like Figure 1-6 As shown, a sheath installation device includes a transfer tube 1, a workbench 2, a first transmission module 3, a second transmission module 4, a mounting base 5, a transmission base 6, a transmission cylinder 7, a stopper 8, and a wire clamping mechanism 9 for fixing a connecting line 11. The transfer tube 1 is a hollow ring body with a mounting block 101 at one end. The workbench 2 is fixedly connected to the first transmission module 3 and the second transmission module 4, which are parallel to each other and have the same structure. The first transmission module 3 is slidably connected to the mounting base 5, and the mounting base 5 is clamped to the transfer tube 1 through the mounting block 101. The wire clamping mechanism 9 is provided on both sides of the mounting base 5. The second transmission module 4 is slidably connected to the transmission base 6, and the stopper 8 is slidably connected to the transmission base 6 through the transmission cylinder 7. Through the combined action of the first transmission module 3, the second transmission module 4, and the transmission cylinder 7, the sheath 10 on the transfer tube 1 is automatically and quickly positioned and installed on the connecting line 11. The sheath can be recycled and installed, improving production efficiency and reducing the labor intensity of workers.

[0028] The first transmission module 3 and the second transmission module 4 are each equipped with a fixed base 31, a first servo motor 32, a synchronous belt 33, and a slide 34. The workbench 2 is fixedly connected to the fixed base 31, which is fixedly connected to the first servo motor 32. The first servo motor 32 is in driving connection with the synchronous belt 33, which is fixedly connected to the slide 34. The slide 34 is slidably connected to the fixed base 31, and the mounting base 5 / transmission base 6 is fixedly connected to the slide 34. Through the closed-loop control of the first servo motor 32, the relative position of the fixed base 31 and the transmission base 6 on the workbench 2 can be accurately controlled, facilitating the accurate positioning of the stopper 8 and pressing the sheath 10 to the preset position of the connecting line 11, thereby improving the stability of the device.

[0029] The transmission base 6 is provided with a rectangular groove 61, through which the stopper 8 is slidably connected to the transmission base 6. One end of the stopper 8 is provided with a first groove 81 for removing the sheath 10. Compared to a conventional circular groove, the rectangular groove 61 of the transmission base 6 prevents the stopper 8 from rotating, preventing the first groove 81 from getting stuck on the sheath 10, and thus providing a more stable structure.

[0030] A position sensor 12 for positioning the slide 34 is provided on one side of the fixed base 31. A stop bar 35 is provided on one side of the slide 34 to trigger the position sensor 12. The position sensor 12 is a photoelectric switch. When the stop bar 35 passes the position sensor 12, it provides feedback on the relative position of the fixed base 31 and the transmission base 6, providing real-time calibration of the servo motor operating parameters.

[0031] The wire clamping mechanism 9 includes a limiting member 91, a locking member 92, a clamping block 93, and a clamping cylinder 94. The limiting member 91 is provided with a first wire groove 95 for positioning the connecting wire 11. The locking member 92 is slidably connected to the clamping block 93. The locking member 92 is fixedly connected to a wire clamping cylinder 94 for controlling the transmission of the clamping block 93. The sliding direction of the clamping block 93 is directly opposite to the first wire groove 95. The mounting seat 5 is provided with a positioning groove 51 that matches the mounting block 101. The two sides of the positioning groove 51 are provided with a second wire groove 52 for limiting the connecting wire 11. The axis center lines of the first wire groove 95 and the second wire groove 52 coincide with each other. The transfer tube 1 is clamped into the mounting seat 5 through the positioning groove 51. The limiting of the first wire groove 95 and the second wire groove 52 facilitates the straightening and fixing of the connecting wire 1. The fixing and removal of the connecting wire 11 are facilitated by the clamping cylinder 94 to meet the process requirements.

[0032] Working principle: After the sheath 10 is pre-installed on the adapter tube 1, the connecting wire 11 passes through the center of the adapter tube 1. After the mounting block 101 of the adapter tube 1 is clamped on the mounting base 5, the adapter tube 1 is parallel to the workbench 2. The connecting wire 11 is naturally placed on the first wire groove 95 and the second wire groove 52. The two ends of the connecting wire 11 are tightly pressed and fixed by the wire clamping cylinder 94. At this time, the fixing of the connecting wire 11 is completed; Figure 7 As shown, the first transmission module 3 After the first sleeve 10 is fixed on the connecting line 11, the first sleeve 10 is fixed on the connecting line 11, and the first sleeve 10 is fixed on the connecting line 11.

[0033] like Figure 8As shown, the present invention also provides a pre-pressing device for a sheath, comprising the aforementioned transfer tube 1, as well as a base plate 15, a linear module 16, a slider 17, a pressure block 18, and a positioning seat 19. The linear module 16 is vertically connected to the base plate 15. The linear module 16 is slidably connected to the slider 17, which is fixedly connected to the pressure block 18. The positioning seat 19 is disposed below the pressure block 18, and the positioning seat 19 is clamped to the transfer tube 1 via a mounting block 101. The linear module 16 comprises a fixed frame 161, a second servo motor 162, and a screw 163. The fixed frame 161 is rotatably connected to the screw 163, the fixed frame 161 is fixedly connected to the second servo motor 162, and the second servo motor 162 is transmission-connected to the slider 17 via the screw 163. One end of the pressure block 18 is provided with a second groove 181 for mounting the sheath 10. The structure of the mounting block 101 on the positioning seat 19 is the same as that of the mounting seat 5. The empty transfer tube 1 is vertically fixed on the positioning seat 19 through the mounting block 101. The worker pre-installs the sheath 10 on the top of the transfer tube 1. The second servo motor 162 controls the pressing block 18 to press the sheath 10 to the preset position and then reset it. The worker pre-installs the next sheath 10 on the transfer tube 1 in time, so that when the sheath 10 is installed subsequently, the block 8 is accurately positioned, and the sheath 10 is accurately positioned and installed on the transfer tube 1 by mechanical means instead of manual work, thereby reducing the labor intensity of the workers.
