Description

Technical Field

[0001] The present invention relates to the technical field of electric fusion sleeve wiring processing, and more particularly to an electric fusion sleeve wiring fixture. Background Art

[0002] Currently, there are two main methods for laying heating wires in the domestic production of electrofusion pipe fittings: pre-embedded and embedded. The pre-embedded method involves winding the heating wire, or a heating wire with enameled wire, onto a pre-molded core, which is then placed into the mold cavity. The product is then injection-molded and demolded, resulting in the electrofusion product containing the heating wire. The other method, to which the present invention is applied, is called embedded, and involves clamping the injection-molded semi-finished clinker pipe fitting onto a CNC lathe. The CNC lathe then embeds a certain amount of heating wire into the inner surface of the product, thereby producing the final electrofusion pipe fitting. However, in the embedded wiring process, the electric fusion sleeve is simple in structure and smooth in product, so it is easy to get fingers pinched when clamped. Since the finger pinching problem is more of an attention problem for employees and is related to the operation method, manufacturers usually start from standardizing operating behaviors to reduce the occurrence of finger pinching problems, but rarely make improvements from the clamping tools. The tooling fixture of the present invention will address this problem and solve the finger pinching problem that frequently occurs in the wiring clamping process of the electric fusion sleeve from the tooling fixture, thereby ensuring the personal safety of employees during operation.

[0003] Due to the product's relatively simple structure and sleek shape, existing fixtures require a human hand to hold the main body of the product, align the electrode column on the product with the electrode column positioning slots on the movable and fixed fixtures, and then activate the pneumatic switch to close the fixture. At this point, the standard hand gesture is to place five fingers together and gently drag the bottom of the product to keep it level to securely close the fixture and clamp the product. However, due to the product's simple structure and sleek appearance, it is easy for it to tilt and fall off during placement. When correcting this, workers often spread their fingers, causing them to be pinched when the fixture closes.

[0004] In view of this, we propose an electric fusion sleeve wiring fixture. Summary of the Invention

[0005] Technical problems to be solved

[0006] The purpose of the present invention is to provide an electric fusion sleeve wiring fixture to solve the problems raised in the above background technology.

[0007] Technical Solution

[0008] The clamping mechanism comprises a clamping mechanism and a sleeve mechanism, wherein the clamping mechanism and the sleeve mechanism cooperate with each other, and the clamping mechanism comprises a collar, a base, an electrode column positioning groove, a base positioning groove, an electric fusion sleeve positioning ring, an auxiliary ring and a clamp fixing screw hole. The side end face of the collar is installed with a base. The setting of the base replaces manual support of the product to ensure the level of the product and prevent the product from being displaced and falling when the clamp is closed; thereby reducing the manual clamping and supporting action, reducing the risk of clamping, and ensuring the safety of clamping. The inner cavity wall of the base is provided with a base positioning groove. The setting of the base positioning groove can be matched with the external structure of the product to better prevent the product from being vibrated and falling when the clamp is closed. The edges of the base are recessed on both sides. There is an electrode column positioning groove, the inner cavity of the ring ring is installed with an electric fusion sleeve positioning ring, and the inner cavity wall of the electric fusion sleeve positioning ring is installed with an auxiliary ring. Through the setting of the electric fusion sleeve positioning ring, the electric fusion sleeve in processing is positioned, the processing deviation is reduced, the consistency of the distribution of the product chamfer, melting zone and cooling zone is ensured, and the product scrap rate is reduced; a circle of auxiliary rings is further set in the inner cavity of the electric fusion sleeve positioning ring, which can strengthen the fixation of the components processed in the device and avoid the product from being offset and damaged during the processing. The outer ring annular array of the side end face of the ring ring is provided with a clamp fixing screw hole. The setting of the clamp fixing screw hole is mainly used for fixing the clamping mechanism and the socket mechanism to ensure that the overall device will not fall off due to rotation during use.

[0009] Preferably, the sleeve mechanism includes a sleeve ring, a bearing film barrel and an electromagnetic pad. The side end surface of the sleeve ring is mounted with the bearing film barrel, and the edge of the bearing film barrel is provided with the electromagnetic pad.

[0010] Preferably, the electromagnetic pad includes a pad body and an electromagnetic plug-in plate. The side end face of the pad body is installed with an electromagnetic plug-in plate. The electromagnetic plug-in plate can be inserted into the inner cavity of the electrode column positioning groove. Through the setting of the electrode column positioning groove, the electrode column positioning groove and the electromagnetic plug-in plate are matched, and can be designed to match the product electrode column structure. It is mainly used for positioning and fixing the product to prevent rotation and displacement during product production. The two sets of pad bodies are clamped at the gap between the base and the carrier tube, so that the components of the inner cavity of the overall device will not slide outward during the wiring process.

[0011] Preferably, the sleeve connection mechanism further comprises a serial rod, and the sleeve connection ring and the clamp fixing screw holes of the sleeve ring are connected in series through the serial rod, so that the clamping mechanism and the sleeve connection mechanism become a whole.

[0012] Preferably, the sleeve connection mechanism further comprises an auxiliary assembly mechanism, and the auxiliary assembly mechanism is mounted on the upper end surface of the base, so that the base and the carrier tube support the auxiliary assembly mechanism.

[0013] Preferably, the auxiliary assembly mechanism includes an auxiliary matching cylinder, a connecting piece belt and a supporting piece, and both ends of the auxiliary matching cylinder are movably connected to both ends of the supporting piece through the connecting piece belt.

[0014] Preferably, the auxiliary matching cylinder includes a cylinder body, a series member and a forming cylinder, the series member is provided on both sides of the inner cavity wall of the cylinder body, and the other end of the series member is installed with a forming cylinder, and through the setting of the series member and the cylinder body, an auxiliary positioning line is inserted into the interval between them, and the thickness of the auxiliary positioning line is greater than the thickness of the wiring, and the auxiliary positioning line is bent with the two end walls of the cylinder body as fulcrums. During the bending process, the auxiliary positioning line can limit and guide the wiring to avoid the occurrence of wiring deviation.

[0015] Preferably, both ends of the forming tube are in contact with the inner cavity walls of the ferrule and the coupling ring. Through the setting of the forming tube, the cooling gas can be connected with its inner cavity as a conveying path. After the cooling gas contacts the inner wall of the forming tube, the temperature is transferred to the outer end wall of the forming tube, which can avoid the situation in which the surface temperature of the processing line rises due to the incomprehensibility between the processing lines during the wiring process.

[0016] Preferably, the supporting sheet includes a layer and a through hole, and the through hole is opened in the middle of the layer. Through the arrangement of the layer and the through hole, the high-temperature gas generated by the friction between the processing lines can be discharged outward through the through hole, avoiding the situation where the temperature in the auxiliary assembly mechanism is too high when the temperature of the cooling gas in the inner cavity of the device is not transmitted to the outer wall of the forming cylinder, thereby improving the safety of the device.

[0017] Beneficial effects

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The setting of the clamp fixing screw holes is mainly used to fix the clamping mechanism and the sleeve mechanism to ensure that the entire device will not fall off due to rotation during use.

[0020] 2. Through the setting of the electrode column positioning groove, the electrode column positioning groove cooperates with the electromagnetic plug-in plate and can be matched with the design according to the product electrode column structure. It is mainly used for positioning and fixing the product to prevent rotation and displacement during the production process. The two sets of pads are clamped at the gap between the base and the carrier tube to prevent the components of the inner cavity of the entire device from sliding outward during the wiring process.

[0021] 3. The setting of the electric fusion sleeve positioning ring can be used to position the electric fusion sleeve in processing, reduce processing deviation, ensure the consistency of the distribution of product chamfers, melting zones and cooling zones, and reduce product scrap rate; an auxiliary ring is further set in the inner cavity of the electric fusion sleeve positioning ring to strengthen the fixation of the components processed in the device and avoid the occurrence of product damage caused by displacement during processing.

[0022] 4. By setting up the bottom support, instead of manually supporting the product, the level of the product is ensured, and the product is prevented from being displaced or falling when the fixture is closed; thereby reducing the manual clamping and supporting actions, reducing the risk of pinching, and ensuring clamping safety.

[0023] 5. By setting the bottom bracket positioning groove, the design can be matched according to the external structure of the product, which can better prevent the product from falling due to vibration during the closing of the fixture.

[0024] 6. Through the arrangement of the series parts and the cylinder, auxiliary positioning lines are interspersed in the intervals. The thickness of the auxiliary positioning lines is greater than the thickness of the wiring. The auxiliary positioning lines are bent with the two end walls of the cylinder as fulcrums. During the bending process, the auxiliary positioning lines can limit and guide the wiring to avoid the deviation of the wiring.

[0025] 7. Through the setting of the forming cylinder, the inner cavity can be used as a conveying path to connect the cooling gas. After the cooling gas contacts the inner wall of the forming cylinder, the temperature is transferred to the outer end wall of the forming cylinder, which can avoid the situation in which the surface temperature of the processing line rises due to the mutual incomprehension between the processing lines during the wiring process.

[0026] 8. Through the arrangement of the layers and the through holes, the high-temperature gas generated by the friction between the processing lines can be discharged outward through the through holes, avoiding the situation where the temperature in the auxiliary assembly mechanism is too high when the temperature of the cooling gas is not transmitted to the outer wall of the forming cylinder, thereby improving the safety of the device.
