Detailed Implementation

[0030] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] The following is combined Figures 1 to 5 An automatic brazing filler for a brazing piston according to an embodiment of the present invention will be described in detail.

[0033] like Figures 1 to 5As shown, an automatic brazing filler for a brazing piston according to an embodiment of the present invention includes: a worktable 102; a first linear guide rail 104 disposed on the worktable 102; a first support plate 106 slidably connected to the first linear guide rail 104 via a first slider 108; a rotary material tray 110 mounted on the first support plate 106; a DC geared motor 112 mounted on the bottom of the first support plate 106; the DC geared motor 112 connected to the rotary material tray 110 and capable of controlling the rotation of the rotary material tray 110; a double-guide rod cylinder 114 mounted on a second support plate 115; the baffle of the double-guide rod cylinder 114 connected to the front end of the first support plate 106; the second support plate 115 mounted on the worktable 102; and the double-guide rod cylinder 114 capable of driving the first support plate 106 to move along the first linear guide rail 104. In the initial state of the rotary material tray 110, an arc plate 116 is installed on the side of the rotary material tray 110 opposite to the double guide rod cylinder 114, that is, at the front end of the rotary material tray 110. A corresponding first proximity switch 118 and second proximity switch 120 are installed on the double guide rod cylinder 114. When the double guide rod cylinder 114 drives the first support plate 106 to move along the first linear guide rail 104, the arc plate 116 approaches the first proximity switch 118 and the second proximity switch 120 installed at the front end of the double guide rod cylinder 114, and triggers the command signal at the same time. At this time, the DC geared motor 112 drives the piston skirt on the rotary material tray 110 to rotate. The third support plate 122 is mounted on the workbench 102 via the column 124. The third support plate 122 is positioned above the double-guide rod cylinder 114. The first cylinder 126 is mounted on the third support plate 122, and its baffle is connected to the second slider 128. The second linear guide rail 130 is mounted on the third support plate 122, and the second slider 128 is mounted on the second linear guide rail 130, allowing it to move along the second linear guide rail 130 under the influence of the first cylinder 126. The first stop bar 132 and the second stop bar 134 are mounted on the third support plate 122, located on the same side of the second linear guide rail 130, and are used to control the extreme positions of the second slider 128. One end of the L-shaped bracket 136 is mounted on the second slider 128, and the other end points vertically downwards. A vibration motor 138 is mounted on its left side, and a second cylinder 140 is mounted on its right side. The baffle of the second cylinder 140 is connected to a positioning block 142 on which a funnel 144 is mounted. The first cylinder 126 drives the L-shaped bracket 136 to move left and right, while the second cylinder 140 drives the funnel 144 to move up and down. The upper part of the funnel 144 is connected to the sample sieve 146 via a nylon ring 148. When the vibration motor 138 is turned on, the brazing filler metal passes through the screen of the sample sieve 146 and falls evenly through the funnel 144 into the brazing filler metal groove of the piston. This automates the brazing filler metal loading of the brazing piston, significantly improving filling efficiency, reducing filling costs, and lowering the labor intensity of workers.

[0034] Furthermore, such as Figures 1 to 5As shown, a high-precision weighing sensor 1102 is integrated within the rotary feed pan 110, which can automatically calculate the weight difference between the piston skirts before and after the filler. This allows an alarm signal to be issued when the weight of the filler metal is outside the set range. A thrust ball bearing 1104 is installed within the rotary feed pan 110 to ensure the horizontal stability of the piston skirts during rotation.

[0035] Furthermore, the rotary tray 110 is a nylon rotary tray 110, which is detachable and replaceable.

[0036] Furthermore, the baffle of the second cylinder 140 is connected to the positioning block 142 by a single screw, so that the positioning block 142 can rotate horizontally, thereby enabling the horizontal position adjustment of the funnel 144.

[0037] Furthermore, the funnel 144 is made of stainless steel, ensuring high reliability. The column 124 consists of four aluminum profiles, providing strong sturdiness.

[0038] Furthermore, such as Figure 1 As shown, the automatic brazing piston loading machine also includes: a protective cover 150, which is fitted over the worktable 102; a safety door 152, which is located on one side of the protective cover 150; a lighting system, which is located inside the protective cover 150; a pneumatic system, which is connected to the double guide rod cylinder 114, the first cylinder 126, and the second cylinder 140 respectively; a PLC control system, which is connected to the vibration motor 138, the DC geared motor 112, the high-precision weighing sensor 1102, the double guide rod cylinder 114, the first cylinder 126, the second cylinder 140, the first proximity switch 118, and the second proximity switch 120 respectively; and a three-color warning light 154, which is located on the top of the protective cover 150.

[0039] Furthermore, the pneumatic system includes air pipes, control valves, and a pneumatic triplet, with a pneumatic pressure of up to 0.5 MPa, and the pneumatic pressure is adjustable.

[0040] The working process of the automatic brazing filler metal loading machine for brazing pistons proposed in this utility model is as follows:

[0041] Press the start switch, the high-precision weighing sensor detects the weight of piston skirt I, then the double guide rod cylinder 114 retracts, and the arc plate 116 on the rotary material tray 110 approaches the first proximity switch 118 and the second proximity switch 120, triggering the command signal, the second cylinder 140 extends, and the stainless steel funnel 144 discharge port moves down accordingly. At this time, the vibration motor 138 and the DC geared motor 112 start simultaneously to complete the filling of brazing filler metal groove I.

[0042] After the piston rotates one revolution, the first cylinder 126 extends, and the discharge port of the stainless steel funnel 144 moves to the left. At this time, the vibration motor 138 and the DC geared motor 112 start again to complete the filling of the brazing filler groove II.

[0043] Finally, the double-guide rod cylinder 114 extends, the piston retracts, and the high-precision weighing sensor 1102 detects the weight II of the piston skirt, which facilitates the automatic calculation of the weight difference of the piston skirt before and after filling. If the weight of the filled brazing filler is not within the set range, the device can issue an alarm signal.
