[0046] A vertical threaded rod 29 is rotatably connected to the connecting frame 26, the threaded rod 29 passes through the adjusting frame 28 and is threadedly connected with the adjusting frame 28, a screw nut can be fixedly installed on the adjusting frame 28, and the threaded rod 29 cooperates with the screw nut.

The connecting frame 26 is further fixedly connected with a light rod 31 which passes through the second mounting slot 38 and cooperates with the adjusting frame 28 in sliding mode. The spacing between the connecting frame 26 and the adjusting frame 28 is adjusted by rotating the threaded rod 29, and the lock housing 52 is clamped.

[0047] In order to avoid the lock housing 52 being in a relatively static state during phosphating, so that the surfaces of the lock housing 52 are difficult to be uniformly phosphated, and the phosphating film thicknesses at different positions are inconsistent, the following scheme is adopted.

[0048] The fixed arm 17 and the movable arm 18 are both rotatably provided with a rotating sleeve 23, a transmission chain 25 is connected between the rotating sleeve 23 and a mounting sleeve 24, the mounting sleeve 24 and the outer wall of the rotating sleeve 23 are both provided with chain teeth which cooperate with the transmission chain 25, so that when the rotating sleeve 23 rotates, the mounting sleeve 24 is driven to rotate by the transmission chain 25.

The rotating sleeves 23 and the mounting sleeve 24 are driven to rotate by the motor 21 output power and the left and right of the driving shaft 22, and in turn drive the connecting frame 26 to rotate. When the connecting frame 26 rotates, the lock housing 52 can be turned over, so that each surface of the lock housing 52 has sufficient opportunity to uniformly contact with the phosphating liquid, thereby improving the quality and effect of phosphating.

[0049] In order to avoid the phosphating liquid of the contact part of the lock housing 52 clamped from penetrating, affecting the phosphating effect, the following scheme is adopted.

[0050] Two first clamping wheels 32 are mounted on the connecting frame 26, and two second clamping wheels 33 are mounted on the adjusting frame 28. The first clamping wheels 32 and the second clamping wheels 33 clamp the lock housing 52, and their axes are in the same direction. During phosphating, the first clamping wheels 32 and the second clamping wheels 33 roll on the lock surface to avoid being clamped in one position, which would make it difficult to phosphate the clamping position. Specifically, a transmission member 40 is slidably mounted on the mounting frame 16. The transmission member 40 includes a sliding part 41 and a frame-shaped part 42, which are fixedly mounted. Fixed shafts 27 are fixedly connected to both the fixed arm 17 and the movable arm 18. The fixed shafts 27 are coaxially arranged with and pass through the mounting sleeve 24. A semi-circular gear 45 is fixedly connected to the fixed shafts 27. A fixed frame 46 is fixedly connected to the frame-shaped part 42. The semi-circular gear 45 is located inside the fixed frame 46. Two opposing transmission racks 47 are fixedly connected to the inner wall of the fixed frame 46, and the semi-circular gear 45 alternately meshes with the two transmission racks 47. A cylindrical gear 51 is coaxially fixed to the second clamping wheel 33, and a linear rack 44 meshing with the cylindrical gear 51 is fixedly connected to the sliding part 41. When the connecting frame 26 rotates, the fixed shaft 27 causes the transmission component 40 to rotate relative to the fixed shaft 27. Under the action of the transmission racks 47 and the semi-circular gear 45, the transmission component 40 and the connecting frame 26 reciprocate relative to each other. Furthermore, under the action of the linear rack 44 and the cylindrical gear 51, the second clamping wheel 33 rolls on the surface of the lock housing 52.

[0051] To prevent the first clamping wheel 32 and the second clamping wheel 33 from detaching from the lock housing 52 when rolling on the lock surface due to differences in lock size, the following solution is adopted:

[0052] The connecting frame 26 has a first mounting groove 34, in which two first mounting parts 36 are slidably connected. A bidirectional lead screw 35 is rotatably mounted in the first mounting groove 34, and the bidirectional lead screw 35 is threadedly engaged with the two first mounting parts 36. The two parts of the bidirectional lead screw 35 that engage with the two first mounting parts 36 have opposite thread directions. A first clamping wheel 32 is rotatably mounted on the first mounting parts 36. The adjusting frame 28 has a second mounting groove 38, in which two second mounting parts 37 are slidably connected. A bidirectional lead screw 39 is rotatably mounted in the second mounting groove 38, and the bidirectional lead screw 39 is threadedly engaged with the two second mounting parts 37. The two parts of the bidirectional lead screw 39 that engage with the two first mounting parts 36 have opposite thread directions. A second clamping wheel 33 is rotatably mounted on the second mounting parts 37.

[0053] In order to improve the draining efficiency of the lock shell 52, the fan 48 is fixedly installed on the side wall of the recovery pool 12, and the lock shell 52 is blown from the inside of the recovery pool 12 through the fan 48. At the same time of blowing, the connecting frame 26 drives the lock shell 52 to overturn, and the first clamping wheel 32 and the second clamping wheel 33 roll on the surface of the lock shell 52, so as to avoid that the phosphating liquid is accumulated at the lower end of the lock shell 52 during the draining, and the lower end of the lock shell 52 is dried last, which causes different phosphating time of different parts, causes appearance difference, and affects the processing quality. At the same time, due to the rotation of the lock shell 52, the phosphating liquid can be thrown off, and the drying efficiency is improved.

[0054] Working or installation process: in the initial state, the mounting frame 16 is located above the phosphating pool 11, and the supporting hydraulic cylinder 15 is in the elongated state.

[0055] 1. According to the size of the lock, rotate the first screw rod 20 to adjust the distance between the movable arm 18 and the fixed arm 17, adjust the distance between the two first clamping wheels 32 and the distance between the two second clamping wheels 33 by rotating the bidirectional screw rod two 39 and the bidirectional screw rod one 35, and then rotate the threaded rod 29 to make the first clamping wheel 32 and the second clamping wheel 33 clamp on both sides of the lock shell 52 respectively.

[0056] 2. By controlling the supporting hydraulic cylinder 15 to contract, the connecting frame 26 enters the phosphating pool 11, and then the lock shell 52 is immersed in the phosphating liquid. At this time, the motor 21 is started to output power, and then the driving shaft 22 drives the rotating sleeve 23 to rotate, and the connecting frame 26 is driven to rotate under the action of the chain 25, so that the lock shell 52 is overturned to ensure that each surface is uniformly phosphated.

[0057] 3. While the connecting frame 26 rotates around the axis of the mounting sleeve 24, the connecting frame 26 and the fixed shaft 27 rotate relatively, at which time the semicircular gear 45 alternately engages with the transmission rack 47, so that the transmission member 40 reciprocates relative to the connecting frame 26, and the first clamping wheel 32 rolls back and forth on the surface of the lock shell 52 under the action of the straight rack 44, so as to adjust the clamping position of the first clamping wheel 32 and the second clamping wheel 33, avoid the phosphating liquid in the clamped contact part, and affect the phosphating effect.

[0058] 4. When phosphating is completed, the mounting frame 16 is moved to the upside of the recovery tank 12 by controlling the extension of the supporting hydraulic cylinder 15 and the movement of the electric sliding table 14, and the lock housing 52 is placed into the recovery tank 12 by the supporting hydraulic cylinder 15, at this time, the motor 21 is still started, and the fan 48 is also started, the connecting frame 26 drives the lock housing 52 to overturn while the fan 48 blows, and the first clamping wheel 32 and the second clamping wheel 33 roll on the surface of the lock housing 52 to avoid the phosphating liquid from gathering at the lower end of the lock housing 52 when it is drained, the lower end of the lock housing 52 is dried at last, which causes the phosphating time of different parts to be different, resulting in appearance difference and affecting the processing quality, and the dripped phosphating liquid can be transported back to the phosphating tank 11 by the recovery pump 49.
