Description

Technical Field

[0001] The present invention relates to the technical field of processing plastic products for the water chambers of automotive radiators, and specifically to an automatic loading and unloading device for radiator water chambers and its universal fixture. Background Art

[0002] An automotive radiator is a main component in an automotive cooling system, which consists of an inlet water chamber, an outlet water chamber, a radiator core, etc. The inlet water chamber and the outlet water chamber are collectively referred to as the radiator water chamber and are injection molded parts. Existing radiator water chambers or intercooler air chambers are generally injection molded at high temperatures. They are all important components for the heat dissipation of automotive engines. After the products are molded, a sprue will be formed at one end of them. Currently, the removal of the sprue is generally manually done with tools, resulting in relatively low processing efficiency.

[0003] To solve the above problems, this case came into being. Summary of the Invention

[0004] (I) Technical Problems to be Solved

[0005] In view of the deficiencies of the prior art, the present invention provides an automatic loading and unloading device for radiator water chambers and its universal fixture, which solves the problems raised in the above background art.

[0006] (II) Technical Solutions

[0007] To achieve the above objectives, the present invention is realized through the following technical solutions: An automatic loading and unloading device for radiator water chambers and its universal fixture, including a feeding conveyor mechanism, a universal fixture, a conduction mechanism, and a pushing mechanism placed in a base, a limiting mechanism, arranged in sequence along the feeding direction. After processing, it is unloaded by an unloading conveyor mechanism to complete a cycle. The universal fixture uniformly flips and corrects the radiator water chambers in polymorphic positions that are inverted and side-mounted. It includes a support ring frame connected to the end of a conveyor belt. There is an annular rotating seat on the support ring frame, which is supported by limiting wheels installed at circumferential intervals on the support ring frame. Among them, tooth teeth are formed on the inner circumference of the annular rotating seat, and a driving gear one is installed at the relative top of the support ring frame. There are at least two air bag parts at relative positions on the annular rotating seat. A cylinder one is provided at the bottom of the support ring frame, and the cylinder one is fixed at the feeding conveyor mechanism.

[0008] As a preferred solution, further, the conduction mechanism includes a support frame. An annular rotating frame is pivotally connected to the support frame. Tooth teeth are provided on the inner peripheral wall of the rotating frame. The interior of the support frame is hollow and is provided with a motor. The output end of the motor drives the rotating frame to rotate through a driving gear two cooperating with the tooth teeth. A short-distance conveying mechanism is arranged on the rotating frame, and the short-distance conveying mechanism is connected to the output end of the feeding mechanism.

[0009] As a preferred solution, further, the rotation of the rotating frame is a counterclockwise rotation of 90° or a clockwise rotation of 90°.

[0010] As a preferred solution, further, a plurality of sensors are arranged at intervals in the length direction on the relatively lower side of the support frame and close to the support ring frame.

[0011] As a preferred solution, further, the pushing mechanism includes a cylinder four connected to the side of the connection and conduction mechanism. The cylinder four is arranged vertically and its output end is connected with a lifting block. A cylinder three is installed on the outer side of the lifting block, and the output end of the cylinder three is connected inward with a pushing block. Under normal conditions, the entire pushing mechanism is located in the base.

[0012] As a preferred solution, further, the limiting mechanism is arranged on both sides of the initial entry position of the radiator water chamber. It includes a long strip-shaped stop edge provided on the base, which is pivotally connected to a corresponding accommodating long groove opened on the base. A limiting strip is connected to the rear side of the stop edge, and guide blocks are placed at intervals in the relative positions of the limiting strip. An extension block is provided at the end of the stop edge. Under normal conditions, the extension block covers the entire pushing mechanism and is flush with the tabletop of the base. Among them, the cylinder four drives the lifting block to lift the extension block so that the stop edge flips 90° to a state perpendicular to the tabletop, and continues to limit the position of the subsequent processing movement of the radiator water chamber.

[0013] As a preferred solution, further, a rotating rod is provided on the other side of the stop edge. A strut is hinged in the middle of the rotating rod so that the inner side is suspended. A lifting cylinder is provided on the outer side and is hinged to the output end of the lifting cylinder. An arc-shaped opening is formed at the inner end of the rotating rod, and a semi-circular notch is provided on the pushing block.

[0014] As a preferred solution, further, a withdrawal cylinder is installed on the lower side of the rotating rod. The withdrawal cylinder laterally pushes the radiator water chamber to the discharge conveying mechanism connected to one side.

[0015] As a preferred solution, further, the distance that the radiator water chamber is pushed forward by the pushing block is greater than the length of the limiting strip.

[0016] (III) Beneficial effects

[0017] After adopting the above technical solution, an automatic loading and unloading device for a radiator water chamber and its general fixture provided by the present invention has the following beneficial effects compared with the prior art: By setting the general fixture, it is possible to flip and uniformly correct the radiator water chambers in various polymorphic positions such as inverted and side-mounted originally, and the rotation process is not affected by the irregular protruding structures of the radiator water chambers.

[0018] Secondly, the setting of the limiting mechanisms on both sides of the radiator water chamber enables it to be restricted to a preset trajectory during conduction and processing to prevent deviation. There is a long strip-shaped retaining edge on the outside, and a limiting strip connected to the rear side thereof. Guide blocks are placed at intervals in the relative positions of the limiting strip. The two work together to prevent the initially entering radiator water chamber from deviating too much to one side. Secondly, the setting of the retaining edge neither affects the entry of the radiator water chamber nor eliminates the influence of the withdrawal of the radiator water chamber after processing.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] In order to make the objectives, technical solutions and advantages of the present invention more clear and understandable, the present invention will be further described in detail below with reference to specific embodiments and the accompanying drawings.

[0027] Referring to the Figure 1-2 figures, an automatic loading and unloading device for a radiator water chamber goes through 5 steps, namely loading - clamping and aligning - rotating and transferring - limiting and pushing, processing - unloading, which are specifically as follows.

[0028] 1. Loading: A conventional feeding and conveying mechanism 1 is adopted, that is, the conveyor belt is driven by a motor for conveying and conduction. In this solution, the radiator water chamber 19 is placed at any position during feeding (that is, there are a large number of inverted and side-mounted situations when introducing the radiator water chamber), and it needs to be conveyed longitudinally at the end for processing. Therefore, a constricting and guiding block 11 is set on the side of the conveyor belt to constrict the discharge port to initially correct the radiator water chamber 19 so that it can enter the general fixture 2 subsequently.

[0029] 2. Post-clamping correction (see attachment Figure 3 ), which is completed by means of the general fixture 2. The general fixture 2 includes a support ring frame 21 connected to the end of the conveyor belt. There is an annular rotating seat 25 on the support ring frame 21, and it is supported by limiting wheels 24 installed circumferentially and spaced on the support ring frame 21. Among them, teeth are formed on the inner circumference of the annular rotating seat 25, and a driving gear 26 is installed at the relative top of the support ring frame 21 (driven to rotate by a motor). The annular rotating seat 25 can be rotated by driving the teeth through the driving gear 26. Secondly, at least two air bag parts 23 are provided at relative positions on the annular rotating seat 25 (the air bag parts 23 adopt a conventional structure, that is, the air bag is expanded by injecting air, and the air bag expands inward to clamp - the radiator water chamber is an injection-molded part, with a light mass and is convenient to be clamped and moved by the air bag). A cylinder 22 is provided at the bottom of the support ring frame 21, and the cylinder 22 is fixed at the feeding and conveying mechanism 1.

[0030] The application process is as follows: After the front part of the radiator water chamber 19 passes through the support ring frame 21, the transmission of the conveyor belt is stopped and air is injected into the air bag. During the expansion process, the radiator water chamber 19 is clamped inwardly. At this time, the cylinder 22 is started to lift the entire support ring frame 21 so that the radiator water chamber 19 is separated from the conveyor belt, and then the annular rotating seat 25 is rotated to synchronously drive the radiator water chamber 19 to the positive position (the original inverted, side-mounted and other polymorphic positions need to be flipped and uniformly corrected. If it is basically in the positive position originally, the above process is not required). Finally, the cylinder 22 is retracted to the initial position to drive the radiator water chamber 19 onto the conveyor belt, and then the air in the air bag is deflated. The radiator water chamber 19 is conveyed to the lower transfer mechanism 3 station through the conveyor belt.

[0031] 3. Rotary transmission (see attachment Figure 1 . 2) It is completed by means of the transmission mechanism 3. The transmission mechanism 3 includes a support frame 31. An annular rotating frame 32 is pivotally connected to the support frame 31. The inner peripheral wall of the rotating frame 32 is provided with teeth. The inside of the support frame 31 is hollow and is provided with a motor. The output end of the motor drives the rotating frame 32 to rotate along its central axis through a driving gear two 33 in cooperation with the teeth. A short-distance conveying mechanism 34 (a conventional component similar to the feeding mechanism) is arranged on the rotating frame 32, and the short-distance conveying mechanism 34 is connected to the output end of the feeding mechanism. It should be noted that the rotating frame 32 rotates counterclockwise by 90° or clockwise by 90° to uniformly turn the incoming radiator water chamber 19 to the front end and enter the subsequent processing position.

[0032] In the previous process, the annular rotating seat 25 needs to synchronously rotate the inverted and side-mounted radiator water chambers 19 to the positive position (such as rotating a and b in the dumping position in the attachment Figure 6 to the positive position c). By means of the long groove structure 192 formed by the depression at the bottom of the radiator water chamber 19, a plurality of sensors 35 (such as laser distance sensors) with intervals in the length direction can be arranged on the relatively lower side of the support frame 31 and close to the support ring frame 21 to determine that the radiator water chamber 19 is rotated to the positive position, that is, when the positions detected by the sensors 35 are all within the long groove structure 192, it is the positive position.

[0033] 4. Limiting and pushing, processing (see the attachment Figure 4-5 ), which is completed by means of the pushing mechanism and the limiting mechanism arranged on the base 5. Among them, the pushing mechanism includes a cylinder four 14 connected to the side of the transmission mechanism 3. The cylinder four 14 is vertically arranged and its output end is connected with a lifting block. A cylinder three 6 is installed on the outside of the lifting block, and the output end of the cylinder three 6 is connected inward with a push block 7. As shown in the attachment Figure 4 , normally the entire pushing mechanism is located inside the base 5, so that the radiator water chamber 19 can be quickly transmitted into the base 5.

[0034] In this solution, the processing of the radiator water chamber 19 is to remove its sprue. That is, the radiator water chamber 19 or the intercooler air chamber is generally injection molded at high temperature, and they are all important components for the heat dissipation of the automobile engine. After the product is formed, a sprue is easily formed at one end. During processing, the radiator water chamber 19 needs to enter completely in the positive direction to be able to cut off the sprue. Therefore, it is necessary to limit the preset trajectory of its entry.

[0035] A rotary cutter head 41 (driven by a motor for operation) is arranged on the base 5 to cut the sprue position of the plastic part. A support plate is movably connected to the front side of the base 5 through a connecting plate. A top rod 42 is axially installed on the support plate. The top rod 42 is located directly above the axial direction of the rotary cutter head 41. Among them, the distance difference between the rear end of the top rod 42 and the rotary cutter head 41 is exactly equal to the distance difference formed by the upper end of the plastic part relative to the bottom sprue. The end of the radiator water chamber 19 entering in the positive direction abuts against the end of the top rod 42 to be able to completely cut off the sprue at the end face.

[0036] There are limit mechanisms on both sides of the initial entry position of the radiator water chamber 19, wherein a long strip-shaped stop edge 8 is provided on the outer side, which is pivotally connected to a corresponding accommodating long groove 16 opened on the base 5 (placed therein and flush with the table surface of the base 5 under normal conditions), as shown in the attached Figure 4 As shown, the rear side of the retaining edge 8 is connected to a limiting strip 15, and a guide block 12 is placed at an interval relative to the limiting strip 15, and the two work together to prevent the radiator water chamber 19 that has just entered from deviating too much to one side. An extension block is provided at the end of the retaining edge 8 (because the radiator water chamber 19 that has just entered will move forward a certain distance due to inertia, so the width of the extension block is set as small as possible to avoid the problem of driving the radiator water chamber 19 to deviate when turning over). Under normal conditions, the extension block merges the entire cover of the pushing mechanism and is flush with the table surface of the base 5. After the radiator water chamber 19 enters, the cylinder 4 14 drives the lifting block to lift the extension block so that the retaining edge 8 turns 90° to a state vertical to the table surface, and continues to limit the position of the subsequent processing movement of the radiator water chamber 19.

[0037] The push block 7 is provided with a semi-arc-shaped notch, which can correspond to the convex column 191 on the rear side of the radiator water chamber 19. The other side of the retaining edge 8 is provided with a rotating rod 10. A support rod is hinged in the middle of the rotating rod 10. The inner side is suspended and the outer side is hinged to the output end of the lifting cylinder 13, so that the inner side can achieve the side wall of the radiator water chamber 19 to be pushed downward. The side edge of the radiator water chamber 19 has an arc transition 193, so the inner end of the rotating rod 10 forms an arc opening, which only applies a force inward to limit its displacement (it can achieve a preliminary pushing effect, and the force should not be too large). The two sides of the radiator water chamber 19 are respectively restricted by the retaining edge 8 and the rotating rod 10, and the material head is removed by entering in a straight line through the push block 7.

[0038] After the cutting process of the material head is completed, the cylinder 3 6 withdraws and drives the lifting block and the pushing block 7 to be retracted into the base 5. At this time, the retaining edge 8 flips to a horizontal state, and the lower side of the rotating rod 10 is also equipped with an exit cylinder 9, which pushes the radiator water chamber 19 horizontally to the material discharging conveying mechanism 18 connected to one side. Since the radiator water chamber 19 is pushed forward for a distance, it will not be blocked by the limit bar 15, and the processing of a radiator water chamber 19 is completed, and this cycle can be carried out later.

[0039] 5. For unloading, a conventional unloading conveying mechanism 18 with the same structure as the feeding part is adopted, and its input end is close to the side of the baffle 8 of the pushing mechanism, so as to facilitate receiving the radiator water chamber 19.

[0040] The specific embodiments described above further elaborate on the objectives, technical solutions, and beneficial effects of the present invention. It should be understood that the above description is only for the specific embodiments of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
