Technical Field
[0001] The utility model relates to the technical field of water pipe joint grooves, in particular to a cooling water pipe joint groove processing device. Background Art
[0002] The engine cooling water pipe joints are crucial components in the cooling system. Made of PA66+35GF, they are responsible for connecting the cooling water pipes and ensuring that the cooling water can circulate within the engine, thereby maintaining the engine's normal operating temperature. Traditional joints require a mounting groove to hold a sealing ring (rubber O-ring). However, if the mounting groove is directly injection molded, it will exist within the joint mold, making it difficult to demold after injection molding, and the mold opening cost is very high. Therefore, the mounting groove adopts a split structure, with the main body only having the lower wall and bottom of the mounting groove, and the upper wall is formed by ultrasonic welding of the injection-molded retaining ring to form the mounting groove. However, the cooling water inside the water pipe often fails to enter the oil, and the retaining ring welding point will fall off due to the expansion of the sealing ring due to pre-oil, making it lose its function.
[0003] In view of the drawbacks of the existing technology, a retaining ring and a joint are integrally formed. Since a sealing ring needs to be installed, a sealing groove is opened at the retaining ring. When grooving the cooling water pipe joint in the existing technology, the cooling water pipe joint is installed on a three-jaw chuck, and a slotting tool is installed on a lathe to slot the cooling water pipe joint. Since the cooling water pipe joint is fixed by the three-jaw chuck, centering correction is required each time the cooling water pipe joint is installed, which can easily lead to deviations in the slotting positions of each cooling water pipe joint, and can also easily cause the tool to over-cut the retaining ring, resulting in damage to the joint.

DETAILED DESCRIPTION
[0023] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.
[0024] Reference Figure 1-Figure 4As shown, the present invention provides: a cooling water pipe joint groove processing device for grooving a water pipe joint body 100, comprising a main body 1, a joint installation assembly 11 mounted on the main body 1, and a groove assembly 12 mounted on the main body 1. The main body 1 is the support frame of the entire device and is made of high-strength alloy material to ensure stability and durability for long-term use. The joint installation assembly 11 includes a limit frame 112 and a limit cylinder 113 rotatably arranged in the limit frame 112. The limit cylinder 113 is provided with a rotating assembly 111 for driving the limit cylinder 113 to rotate. The rotating assembly 111 is usually driven by a motor and connected to the limit cylinder 113 through a gear or belt transmission system to provide smooth and controllable rotational power. A joint installation hole 1132 for loading the water pipe joint body 100 is opened at the center of the limit cylinder 113. The joint installation hole 1132 precisely matches the external dimensions of the water pipe joint body 100 to ensure the fit between the two and reduce processing errors. A fixing assembly 114 for fixing the water pipe connector body 100 is provided in the limiting cylinder 113. The fixing assembly 114 is used to firmly fix the water pipe connector body 100 in the limiting cylinder 113 to prevent it from moving during processing, thereby ensuring the consistency and safety of processing. A support ring for supporting the step of the water pipe connector body 100 is also provided on the side wall of the connector mounting hole 1132. When the water pipe connector body 100 is vertically inserted into the connector mounting hole 1132, the step at the lower part of the water pipe connector body 100 is against the support ring.
[0025] Embodiment 1: The fixing assembly 114 includes a clamping member 1144 with rotational motion, and the clamping members 1144 are provided with at least two. The position where the clamping member 1144 contacts the water pipe connector body 100 is set to be arc-shaped. The arc-shaped clamping member 1144 can better fit the outer surface of the water pipe connector body 100, reduce friction and wear, and ensure a stable clamping effect. The fixing assembly 114 also includes a driving mechanism for driving the clamping member 1144 to rotate. The driving mechanism in the fixing assembly 114 includes a telescopic driving member 1141, which is fixed to the inside of the limiting cylinder 113. The output end of the telescopic driving member 1141 is connected to It is connected to a movable plate 1142, on which a transmission rod 1143 is movably provided through an axis, one end of the transmission rod 1143 is movably connected to the clamping piece 1144, and a connecting block 1145 is also installed inside the limit cylinder, and the clamping piece 1144 is rotatably connected to the connecting block 1145. The telescopic driving piece 1141 usually adopts an electric, pneumatic or hydraulic driving method. When the telescopic driving piece 1141 is working, it will push or pull the movable plate 1142 to move in a straight line. When the movable plate 1142 moves, the transmission rod 1143 will swing accordingly, thereby driving the clamping piece 1144 to rotate and fix the water pipe joint body 100.
[0026] When the water pipe connector body 100 needs to be secured, the telescopic drive member 1141 is activated, pushing the movable plate 1142 forward. The movement of the movable plate 1142 is transmitted to the clamping member 1144 via the transmission rod 1143, causing the clamping member 1144 to rotate about the connecting block 1145 until the curved portion of the clamping member 1144 closely contacts the outer surface of the water pipe connector body 100. At this point, the clamping force generated by the clamping member 1144 firmly secures the water pipe connector body 100 in the retaining cylinder 113, providing stable support for subsequent processing operations.
[0027] In the second embodiment, the fixing assembly 114 includes a reciprocating clamping member 1144, at least two clamping members 1144 are provided, and the position where the clamping member 1144 contacts the water pipe connector body 100 is arranged in an arc shape. The fixing assembly 114 also includes a linear drive device for driving the clamping member 1144 to move back and forth.
[0028] When the water pipe connector body 100 needs to be secured, the linear drive is activated, pushing the clamping member 1144 along a specific path toward the water pipe connector body 100. As the clamping member 1144 gradually approaches, the contact area between the clamping member 1144 and the water pipe connector body 100 gradually increases until the predetermined clamping force is reached. At this point, the water pipe connector body 100 is firmly fixed in the retaining cylinder 113, providing stable support for subsequent processing operations.
[0029] The rotating component 111 includes a first rotating driving member 1111 and a second pulley 1113. The second pulley 1113 is fixed at the bottom of the limiting cylinder 113. The output end of the first rotating driving member 1111 is fixed with a first pulley 1112. The first pulley 1112 and the second pulley 1113 are connected by a belt. A ring rail 1131 is also fixed to the outside of the limiting cylinder 113. The rotating component 111 also includes a guide wheel 1114, which cooperates with the ring rail 1131.
[0030] When first rotary drive member 1111 is activated, it rotates first pulley 1112. This rotational motion is transmitted to second pulley 1113 via a belt drive, thereby rotating stop cylinder 113. Simultaneously, guide wheel 1114 rolls on ring rail 1131, ensuring smooth and accurate rotation of stop cylinder 113.
[0031] refer to Figure 5 and Figure 6As shown, the slotting assembly 12 includes a lifting assembly 121 and a tool assembly 122 arranged on the lifting assembly 121. The lifting assembly 121 is used to drive the tool assembly 122 to move downward so that the tool assembly 122 extends into the water pipe connector body 100. The tool assembly 122 includes a tool holder 1221 and a tool head 1224 arranged in the tool holder 1221. The tool head 1224 is arranged near the bottom end of the tool holder 1221. The tool head 1224 can be moved out of the tool holder 1221 for contacting the inner wall of the water pipe connector body 100. A rotatable turntable 1223 is also provided in the tool holder 1221. An arc groove 1225 is provided on the turntable 1223. A limiting shaft is also provided on the top of the tool head 1224, and the limiting shaft can move in the arc groove 1225. A third rotary driving member 1222 is also installed in the tool holder 1221, and the output end of the third rotary driving member 1222 is connected to the turntable 1223.
[0032] When grooving is required, the lifting assembly 121 is activated, pushing the lifting platform and the cutter assembly 122 downward until the cutter head 1224 extends into the interior of the water pipe connector body 100. The third rotary drive member 1222 is then activated, driving the turntable 1223 to rotate, thereby adjusting the cutting position of the cutter head 1224. As the turntable 1223 rotates, the limiting shaft moves within the arc-shaped slot 1225, causing the cutter head 1224 to contact the inner wall of the water pipe connector body 100 to perform grooving.
[0033] The lifting assembly 121 includes a fixed plate 1211, a second rotating driving member 1212 is fixed on one side of the top of the fixed plate 1211, a third pulley 1213 is fixed on the second rotating driving member 1212, a threaded rod 1215 is also movably provided on the fixed plate 1211, a fourth pulley 1214 is fixed at one end of the threaded rod 1215, the third pulley 1213 and the fourth pulley 1214 are connected by a belt, a lifting plate 1216 is also provided on the threaded rod 1215, and the knife seat 1221 is fixed on the lifting plate 1216.
[0034] When the second rotary drive member 1212 is activated, it drives the third pulley 1213 to rotate. Through a belt drive, the rotational motion of the third pulley 1213 is transmitted to the fourth pulley 1214, which in turn drives the threaded rod 1215 to rotate. Because the lifting plate 1216 and the threaded rod 1215 are threaded together, the rotational motion of the threaded rod 1215 is converted into linear motion of the lifting plate 1216. By controlling the rotational direction and speed of the second rotary drive member 1212, precise lifting and lowering control of the tool assembly 122 can be achieved.
[0035] Working principle: When in use, the water pipe connector body 100 is inserted into the connector mounting hole 1132, and then, by starting the telescopic driving member 1141, the telescopic driving member 1141 moves the movable plate 1142, and the movable plate 1142 moves the transmission rod 1143, so that the clamping member 1144 is clamped to the outside of the water pipe connector body 100, and then, by starting the second rotating driving member 1212, the second rotating driving member 1212 rotates the third pulley 1213, and the third pulley 1213 drives the fourth pulley 1214 to rotate through the belt, thereby rotating the threaded rod 1215, and the threaded rod 1215 moves the lifting plate 1216 downward, so that the knife holder 1221 is inserted to In the water pipe connector body 100, then, by starting the third rotary drive member 1222, the third rotary drive member 1222 moves the turntable 1223, and then the cutter head 1224 extends from the cutter seat 1221, and then, by starting the first rotary drive member 1111, the first rotary drive member 1111 rotates the first pulley 1112, and then rotates the second pulley 1113, so that the limiting cylinder 113 rotates and drives the water pipe connector body 100 to rotate. When the water pipe connector body 100 rotates, the cutter head 1224 grooves the water pipe connector body 100. The device is suitable for large-scale processing, so that the groove depth of each water pipe connector body 100 is consistent, thereby improving the groove accuracy.
[0036] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
