[0072] The following are specific embodiments of the present utility model, and the technical solutions of the present utility model will be further described in conjunction with the accompanying drawings, but the present utility model is not limited to these embodiments.

[0073]

Embodiment 1

[0074] As Figures 1 - 3 shown, a cable nut installation device for the upper cover of a water pump includes a frame 6, and the following are provided on the frame 6:

[0075] A loading device 1, on which a placement table 104 is provided, and a number of processing positions 101 are provided on the placement table 104, and the processing positions 101 are used to place the upper cover 5 of the water pump to be assembled.

[0076] Before the cable nut 52 is tightened, the cable 51 will be passed through the cable nut 52 first to facilitate subsequent connection of the cable 51. Therefore, the cable 51 will extend above the upper cover 5 of the water pump to be assembled. Now, before the cable nut 52 is screwed, it is necessary to fix the cable 51 to prevent the cable 51 from tilting and shaking during the process of screwing the cable nut 52, which may affect normal assembly or cause damage to the cable 51.

[0077] Therefore, a cable holder 103 is also provided on the processing position 101, and the cable holder 103 is used to support the cable 51 extending out of the upper cover 5 of the water pump.

[0078] The loading device 1 can drive the upper cover 5 of the water pump to move from one processing position 101 to the next processing position 101.

[0079] An installation frame 200 is further provided on the frame 6, and a sliding table 201 and a first horizontal moving mechanism 230 are movably provided on the installation frame 200, and a screwing device 2 is provided on the sliding table 201.

[0080] When the loading device 1 moves the upper cover 5 of the water pump to be assembled below the screwing device 2, the first horizontal moving mechanism 230 will drive the sliding table 201 to move in a reciprocating linear motion along a set direction, so that the screwing device 2 can be connected to the cable nut 52 on the upper cover 5 of the water pump to be assembled and perform a screwing action on the cable nut 52, or separate the screwing device 2 from the tightened cable nut 52.

[0081] In this embodiment, the first horizontal moving mechanism 230 includes a driving cylinder 231, and a push rod 232 of the driving cylinder 231 is connected to the sliding table 201, so that the driving cylinder 231 can drive the sliding table 201 to move.

[0082] The screwing device 2 includes:

[0083] The screwing head 210 is formed with a wrench opening 211, and the wrench opening 211 is sleeved outside the cable nut 52 on the upper cover 5 of the water pump to perform the screwing work;

[0084] The driving source 220 is used to drive the screwing head 210 to rotate;

[0085] When the upper cover 5 of the water pump is at the processing position 101 below the screwing device 2, the horizontal moving mechanism 230 drives the sliding table 201 to move along the opening direction of the wrench opening 211, so that the screwing head 210 can be sleeved outside the cable nut 52 of the upper cover 5 of the water pump to be assembled.

[0086] As Figure 1 and Figure 2 shown, a fixing device 3 is further provided on the frame 6, and the fixing device 3 is arranged below the screwing device 2.

[0087] When the upper cover 5 of the water pump to be assembled is at the processing position 101, the fixing device 3 will fix the position of the upper cover 5 of the water pump to facilitate the accurate connection between the screwing device 2 and the cable nut 52.

[0088] Further, the fixing device 3 includes:

[0089] The driving cylinder three 301;

[0090] At least two chucks 302 are formed with arc-shaped notches 303 whose shapes match the contour of the upper cover 5 of the water pump, and a rubber gasket 304 is arranged at the edge of the arc-shaped notch 303.

[0091] The driving cylinder three 301 is used to drive the chuck 302 to clamp on the circumferential side of the upper cover 5 of the water pump to fix the position of the upper cover 5 of the water pump.

[0092] The rubber gasket 304 is used to fit on the side wall of the upper cover 5 of the water pump. Since the rubber gasket 304 has elasticity, the rubber gasket 304 can better fit on the surface of the chuck 302. When the chuck 302 clamps the upper cover 5 of the water pump, an additional frictional force is generated, further improving the effect of fixing the upper cover 5 of the water pump and preventing the upper cover 5 of the water pump from moving.

[0093] Further, an avoidance groove two 305 is formed on the chuck 302, and the avoidance groove two 305 is used to leave enough space to avoid the protrusions on the outer side wall of the upper cover 5 of the water pump, so that the arc-shaped notch 303 drives the rubber gasket 304 to fit on the outer side wall of the upper cover 5 of the water pump.

[0094] As Figure 3 and Figure 4 shown, the driving source 220 is a motor, and a driving gear 221 is sleeved on the driving shaft of the driving source 220.

[0095] Above the screwing head 210, a gear disc 212 is connected. An avoidance groove one 213 is formed on the gear disc 212. The opening direction of the avoidance groove one 213 is the same as that of the wrench opening 211. And the projection of the avoidance groove one 213 on the horizontal plane covers the wrench opening 211.

[0096] The driving gear 221 can drive the gear disc 212 to rotate, so as to drive the screwing head 210 to rotate.

[0097] When the screwing head 210 cooperates with the cable nut 52, the cable 51 can extend out through the avoidance groove one 213. This can not only prevent the cable 51 from being damaged due to bending, but also ensure that the cable 51 does not prevent the normal rotation of the gear disc 212.

[0098] In this embodiment, the driving gear 221 and the gear disc 212 are connected by a transmission gear 222. Since the size and mass of the gear disc 212 are both larger than those of the driving gear 221, when the driving gear 221 drives the gear disc 212 to rotate, the teeth in contact between the driving gear 221 and the gear disc 212 need to bear a large pressure, so the teeth are prone to wear. In this embodiment, by setting two transmission gears 222, the driving gear 221 drives the transmission gear 222 to rotate first, and then drives the gear disc 212 to rotate, which is equivalent to increasing the contact area of the teeth of the driving gear 221 at the same time. And since the force required to drive the gear disc 212 remains unchanged, the pressure per unit area applied to the teeth of the driving gear 221 will also be reduced accordingly, so as to protect the teeth of the driving gear 221.

[0099] Furthermore, a bearing part 202 is arranged on the sliding table 201, and the gear disc 212 is arranged on the bearing part 202, so that the gear disc 212 can partially extend out of the mounting frame 200, thus leaving enough space below the gear disc 212 to connect the screwing head 210.

[0100] As Figure 1 and Figure 3 shown, a protective shell 203 is also arranged outside the screwing device 2. The protective shell 203 is used to protect the screwing device 2, mainly to protect the rack 215 of the gear disc 212 and prevent the rack 215 of the gear disc 212 from deforming.

[0101] An avoidance notch 204 is opened on the protective shell 203, and the avoidance notch 204 is used for the cable 51 to pass through.

[0102] Specifically, as Figure 8 and Figure 9As shown, the position of the cable rack 103 is higher than the upper end of the protective case 203. When the screwing device 2 moves above the upper cover 5 of the water pump to be assembled, the cable rack 103 can fix the upper end of the cable 51 to prevent the cable 51 from interfering with the rotation of the gear disc 212 and the screwing head 210.

[0103] Specifically, as Figure 1 , Figure 7 , Figure 8 and Figure 9 shown, a discharging device 4 is further provided on the frame 6. The loading device 1 can transport the assembled upper cover 5 of the water pump to the discharging position, and the discharging device 4 is used to remove the upper cover 5 of the water pump at the discharging position from the loading device 1;

[0104] The discharging device 4 includes:

[0105] A discharging fixture 410, which is used to clamp the upper cover 5 of the water pump;

[0106] A vertical moving mechanism 430, the discharging fixture 410 is arranged on the vertical moving mechanism 430, and the vertical moving mechanism 430 is used to drive the discharging fixture 410 to move in the vertical direction;

[0107] A horizontal moving mechanism II 440, which is used to drive the vertical moving mechanism 430 to move in the horizontal direction.

[0108] Through the cooperation of the vertical moving mechanism 430 and the horizontal moving mechanism II 440, the discharging fixture 410 can timely remove the assembled upper cover 5 of the water pump on the loading device 1 from the loading device 1.

[0109] A cushion block 412 is connected to the end of the clamping jaw 411 of the discharging fixture 410. When the discharging fixture 410 clamps the upper cover 5 of the water pump, the cushion block 412 on the clamping jaw 411 can fit on the outer side of the upper cover 5 of the water pump, so as to increase the friction force generated when clamping the upper cover 5 of the water pump and prevent the upper cover 5 of the water pump from falling off.

[0110] The discharging device 4 can also cooperate with other equipment to directly send the assembled upper cover 5 of the water pump to the next assembly link, so that the overall assembly process of the water pump is more automated and the production efficiency of the water pump is improved.

[0111] Such as Figure 1 , Figure 7 , Figure 8 and Figure 9 shown, the discharging device 4 further includes a cable clamp 420. The cable clamp 420 is used to fix the cable 51, and the lower end of the clamping arm 421 of the cable clamp 420 should be higher than the upper end of the cable rack 103 to facilitate clamping the cable 51.

[0112] The cable clamp 420 is arranged on the vertical moving mechanism 430, enabling the cable clamp 420 to move synchronously with the unloading fixture 410.

[0113] Moreover, the width of the clamping arms 421 of the cable clamp 420 is also greater than that of the clamping jaws 411 of the unloading fixture 410, so that when the clamping arms 421 approach each other, a larger clamping area can be obtained, making it more convenient to clamp the cable 51.

[0114] Through the cooperation of the unloading fixture 410 and the cable clamp 420, the unloading device 4 can respectively fix the upper cover 5 of the water pump and the cable 51 extending from the upper cover 5 of the water pump during unloading, thereby enabling the upper cover 5 of the water pump to be transported more stably and safely.

[0115] Specifically, as shown in Figure 1 、 Figure 2 、 Figure 5 and Figure 6 , an anti-slip pad 102 is arranged on the processing position 101, and the upper cover 5 of the water pump is arranged on the anti-slip pad 102. The anti-slip pad 102 is used to increase the friction force generated at the bottom end of the upper cover 5 of the water pump and limit the horizontal movement of the upper cover 5 of the water pump, so as to ensure that the screwing device 2 can accurately cooperate with the cable nut 52 on the upper cover 5 of the water pump.

[0116] The anti-slip pad 102 and the processing position 101 are connected by a locking mechanism 11, and the locking mechanism 11 includes:

[0117] A lock core, which is formed with a handle part 111 and a lock rod part 112, and the lock core can be rotated through the handle part 111;

[0118] A limiting block 120, which is inserted through the anti-slip pad 102. A limiting groove 121 is formed on the limiting block 120, and the lock rod part 112 can be inserted into the limiting block 120.

[0119] A locking block 130, which is arranged on the processing position 101. An unlocking hole 131 is formed on the locking block 130, and the lock rod part 112 can be inserted into the locking block 130.

[0120] A limiting post 113 and a locking post 114 are convexly formed on the circumferential side of the lock core. When the lock rod part 112 is inserted between the limiting block 120 and the locking block 130 at the same time, the limiting post 113 is located in the limiting groove 121, and the locking post 114 is located below the locking block 130.

[0121] When the lock core is rotated to move the limit post 113 to one end of the limit slot 121, the position of the locking post 114 is not aligned with the unlocking hole 131, so that the lock rod portion 112 cannot be separated from the locking block 130; and when the limit post 113 is moved to the other end of the limit slot 121, the locking post 114 is aligned with the unlocking hole 131, and at this time, the lock rod portion 112 can be separated from the locking block 130, so as to facilitate the removal of the anti-slip pad 102 from the processing position 101.

[0122] In this embodiment, the loading device 1 is a dividing plate, and four cable racks 103 and a processing position 101 are arranged on the dividing plate. Thus, the device can simultaneously perform the feeding action, the screwing action and the discharging action, improving the assembly efficiency of the water pump upper cover 5.

[0123]

Embodiment Two

[0124] Specifically as Figure 2 and Figure 3 shown, this embodiment is basically the same as Embodiment One, the difference lies in:

[0125] The screwing head 210 and the gear disk 212 are connected by a connecting piece 216.

[0126] A through groove 217 is formed on the connecting piece 216. The upper end of the through groove 217 is communicated with the first avoidance groove 213, and the lower end of the through groove 217 is communicated with the wrench opening 211. Since the structures and sizes of different water pump upper covers 5 are not the same, the connecting piece 216 can leave enough space between the screwing head 210 and the gear disk 212 to avoid collision between the water pump upper cover 5 and the gear disk 212 during the screwing action.

[0127] The through groove 217 is used to leave space for the cable 51 to pass through, so as to avoid the cable 51 interfering with the rotation of the gear disk 212 and the screwing head 210.

[0128] Furthermore, the first horizontal movement mechanism 230 and the sliding table 201 are arranged on the lifting plate 251. A plurality of positioning rods 252 are arranged on the mounting frame 200. The lifting plate 251 is sleeved on the positioning rods 252, and the lifting plate 251 can move up and down along the positioning rods 252.

[0129] A height adjusting assembly 250 is arranged below the lifting plate 251. The height adjusting assembly 250 includes a second driving cylinder 253. The push rod two 254 of the second driving cylinder 253 is connected to the lifting plate 251, so that the second driving cylinder 253 can drive the lifting plate 251 to rise or fall.

[0130] Thus, the position of the screwing head 210 can be adjusted by the height adjusting assembly 250, so that the height of the screwing head 210 can match different sizes and specifications of the water pump upper cover 5, and the cable nut 52 on the water pump upper cover 5 can be assembled.

[0131] It should be noted that the maximum height at which the height adjustment assembly 250 drives the screwing device 2 to rise will not make the upper end surface of the protective case 203 higher than the cable rack 103, so as to ensure that the cable rack 103 can always stably fix the cable 51, facilitating the screwing device 2 to perform the screwing action.

[0132] It should be known that the structures, ratios, sizes, etc. shown in the drawings of this specification are only used to cooperate with the content disclosed in the specification for those familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present utility model.
