Description

Technical Field

[0001] This utility model relates to the field of workpiece processing production line technology, and in particular to a tooling loading and unloading quick change device. Background Technology

[0002] In production lines that process workpieces, the workpieces are often first fixed in fixtures, and then the fixtures carrying the workpieces are sent along the production line to the processing station for processing. However, the workpieces themselves are heavy, and with the added weight of the fixtures that hold the workpieces, the process of transferring the fixtures carrying the workpieces into the production line is quite difficult. In view of this, there is an urgent need to improve the production line to make it easier to transport the fixtures carrying the workpieces to the production line. Utility Model Content

[0003] The purpose of this utility model is to provide a tooling loading and unloading quick change device, so that fixed tooling loaded with workpieces can be conveniently sent into the production line.

[0004] To achieve the above objectives, this utility model provides a tooling loading and unloading quick change device for production line guide rails, including a traveling tray and a movable mold changing trolley. The traveling tray is set on the production line guide rail and slides with the production line guide rail. The mold changing trolley is set on one side of the production line guide rail and moves with the traveling tray.

[0005] The mold changing trolley includes a trolley body, with conveying rails on both sides of the upper surface of the trolley body. The conveying rails extend along the length of the trolley body, and a base plate is provided above the conveying rails. The base plate slides with the conveying rails and is adapted to the accompanying tray.

[0006] To address the difficulty of transferring fixed fixtures from fixed workpieces to the production line guide rails, this application provides a mold-changing trolley. The mold-changing trolley is freely movable; when it is necessary to transfer the fixed fixture, it can be moved from the mold-changing trolley to the production line guide rails. The mold-changing trolley is equipped with a base plate, on which the fixed fixture can be placed. The base plate slides against the conveyor rail, allowing the fixed fixture to be transferred by manually pushing the base plate.

[0007] The conveying track includes a flat guide rail, a vertical guide rail, and an L-shaped mounting base. The flat guide rail has a base at its bottom, and the base is laid on the upper surface of the vehicle body along the length of the vehicle body. The L-shaped mounting base is located at the edge of the vehicle body, and the vertical guide rail is placed on the L-shaped mounting base. A gap is left between the vertical guide rail and the flat guide rail.

[0008] The flat guide rail extends along the length of the vehicle body and is laid on the vehicle body via the base. The vertical guide rail is set on the L-shaped mounting base. Both the vertical guide rail and the flat guide rail are provided with a number of rollers. The rollers in the flat guide rail are arranged parallel to the upper surface of the vehicle body, and the rollers in the vertical guide rail are arranged perpendicular to the upper surface of the vehicle body. The gap formed between the flat guide rail and the vertical guide rail is used to cooperate with the base plate to restrict and guide the movement path of the base plate on the vehicle body.

[0009] The L-shaped mounting base plate is also provided with a plurality of positioning pin holes, which are arranged along the length extension direction of the L-shaped mounting base plate.

[0010] The positioning pin hole is located on the bottom side of the L-shaped mounting base plate and cooperates with the base plate component, so that the base plate component can be fixed in the positioning pin hole.

[0011] The base plate includes a support plate, and the edge of the support plate is provided with a positioning pin that fits into the positioning pin hole. The lower surface of the support plate is provided with a fitting block and a locking part. The fitting block is placed in the gap and fits against the vertical guide rail. The locking part is fixedly connected to the support plate and faces the accompanying tray.

[0012] The support plate is used to hold the fixture for the workpiece to be processed. In this application, the fixture is fixed to the support plate and moves with the support plate. The locking part is connected to the production line guide rail. The support plate is manually pushed into the production line guide rail, which makes it relatively convenient to send the fixture into the production line guide rail. The locking block is used to restrict the movement path of the support plate. The locking part is adapted to the production line guide rail so that the support plate can stay at the predetermined position of the production line guide rail after entering the production line guide rail.

[0013] The mold-changing trolley also includes a connecting rail, which is located on the side of the trolley body near the accompanying tray. The connecting rail is a square column with several rotatable rollers extending along its length.

[0014] The connecting track is equipped with several rollers that rotate on the column. After the bearing plate enters the connecting track, it cooperates with the rollers to facilitate conveying into the production line guide rail. The connecting track is located on one side of the vehicle body and is mainly used as a supplement to the transport track.

[0015] The accompanying tray includes a tray body and a slider, the slider being disposed on the underside of the tray body and adapted to the production line guide rail.

[0016] The disc is used to transport the support plate and the fixed fixture on it to the production line guide rail. After the fixed fixture enters the production line track with the support plate, it moves with the production line guide rail through the slider. The disc is also equipped with a power source. The output end of the power source rotates and drives the disc to move along the production line guide rail in a gear transmission manner. Because it has many existing technologies, this application does not describe it in detail.

[0017] The disc body is provided with a lifting mold and a docking joint. The lifting mold is located at the edge of the disc body, and the docking joint has a guide opening. The docking joint is connected to the base plate through the guide opening.

[0018] The lifting member is disposed on the upper side of the disk body. After the support plate enters the disk body, the lifting member can be activated when the support plate needs to be removed from the disk body, thereby reducing the frictional force of the support plate removing from the disk body.

[0019] The lifting component includes a shell, several spherical bodies, and a connecting plate. The shell has a strip-shaped structure. The several spherical bodies are distributed along the length of the shell and are movably fitted with the shell. The connecting plate connects the several spherical bodies and is disposed inside the shell.

[0020] After the workpiece is delivered above the lifting mold, several spherical bodies fall with the connecting plate. After processing on the production line guide rail, they are inflated, causing the connecting plate to lift the spherical bodies. After the spherical bodies are lifted, the workpiece is lifted, and the contact area between the workpiece and the accompanying tray is reduced, making it easier for the workpiece to be removed from the accompanying tray.

[0021] The housing has a movable cavity, and the top of the movable cavity has several movable holes, each corresponding to a spherical body. The movable cavity is also connected to a gas channel, which is distributed on both sides of the movable cavity.

[0022] The movable cavity provides space for the plate to move. After the gas channel is filled with gas, the connecting plate can be lifted, thereby driving the spherical bodies to move upward and lift the workpiece. At the same time, it can also reduce the contact area between the workpiece and the entire accompanying tray, thus making it easier to remove the workpiece from the accompanying tray.

[0023] This utility model discloses a quick-change tooling loading and unloading device. Based on existing technology, it addresses the problem of difficulty in loading and unloading workpieces on the production line by setting up a mold-changing trolley. After placing the fixed tooling carrying the workpiece onto the mold-changing trolley, it can be connected to the production line guide rail via the mold-changing trolley. The mold-changing trolley is equipped with a conveyor rail, which cooperates with the accompanying pallet to facilitate the transfer of the fixed tooling carrying the workpiece from the mold-changing trolley to the production line guide rail, thereby improving the convenience of fixed tooling transfer.

[0033] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0034] Please see Figures 1 to 3 This utility model provides a tooling loading and unloading quick change device for a production line guide rail 3, including a traveling tray 1 and a movable mold changing trolley 2. The traveling tray 1 is set on the production line guide rail 3 and slides with the production line guide rail 3. The mold changing trolley 2 is set on one side of the production line guide rail 3 and moves with the traveling tray 1.

[0035] The mold changing trolley 2 includes a body 11, and conveying rails 12 are provided on both sides of the upper surface of the body 11. The conveying rails 12 extend along the length of the body 11. A base plate 13 is also provided above the conveying rails 12. The base plate 13 slides with the conveying rails 12 and is adapted to the accompanying tray 1.

[0036] In this embodiment, the accompanying tray 1 is used to move the fixed fixture 4 with the workpiece fixed on the production line guide rail 3, while the vehicle body 11 is mainly used to transport the fixed fixture 4 and improve the convenience of moving the fixed fixture 4 from the vehicle body 11 to the production line guide rail 3. After the conveying track 12 cooperates with the base plate 13, it can be transferred manually.

[0037] Furthermore, the conveying track 12 includes a flat guide rail 121, a vertical guide rail 122, and an L-shaped mounting base 123. The flat guide rail 121 has a base 124 at its bottom. The base 124 is laid on the upper surface of the vehicle body 11 along the length direction of the vehicle body 11. The L-shaped mounting base 123 is disposed at the edge of the vehicle body 11. The vertical guide rail 122 is placed on the L-shaped mounting base 123. A gap 125 is left between the vertical guide rail 122 and the flat guide rail 121.

[0038] The flat guide rail 121 is laid on the vehicle body 11 in a manner parallel to the surface of the vehicle body 11. The L-shaped mounting base plate 123 has an L-shaped structure. The vertical guide rail 122 is disposed on the plate on the vertical side of the L-shaped mounting base plate 123 and is perpendicular to the surface of the vehicle body 11. The gap 125 formed by the vertical guide rail 122 and the mating block 133 guides and restricts the movement path of the mating block 133.

[0039] Furthermore, the L-shaped mounting base plate 123 is also provided with a plurality of positioning pin holes 126, which are arranged along the length extension direction of the L-shaped mounting base plate 123.

[0040] The positioning pin hole 126 is provided along the length extension direction of the L-shaped mounting base plate 123, and the positioning pin hole 126 is provided to facilitate the stable placement of the base plate 13 on the vehicle body 11.

[0041] Furthermore, the base plate 13 includes a support plate 131, and the edge of the support plate 131 is provided with a positioning pin 132 that engages with the positioning pin hole 126. The lower surface of the support plate 131 is provided with a fitting block 133 and a locking part 134. The fitting block 133 is placed in the gap 125 and fits against the vertical guide rail 122. The locking part 134 is fixedly connected to the support plate 131 and faces the accompanying tray 1.

[0042] Please see Figures 4 to 5 The bearing plate 131 is mainly used to support the fixed tooling 4. The positioning pin 132 is inserted into the positioning pin hole 126 to fix the bearing plate 131 on the vehicle body 11. The engaging block 133 fits against the vertical guide rail 122 to restrict the lateral movement of the bearing plate 131 during its movement. The locking part 134 is used to allow the bearing plate 131 to engage with the accompanying pallet 1 to restrict the position of the bearing plate 131 on the production line guide rail 3.

[0043] Furthermore, the mold changing trolley 2 also includes a connecting track 14, which is disposed on the side of the trolley body 11 near the accompanying tray 1. The connecting track 14 is a square column with a plurality of rotatable rollers 141 extending along its length.

[0044] In this embodiment, the connecting track 14 is used to fill the gap between the carrier plate 131 and the accompanying tray 1, so that the carrier plate 131 can enter the production line guide rail 3 through the connecting track 14 during transportation.

[0045] Furthermore, the accompanying tray 1 includes a tray body 21 and a slider 22, the slider 22 being disposed on the lower side of the tray body 21 and adapted to the production line guide rail 3.

[0046] Different fixing fixtures 4 can be set on the disc body 21. After the slider 22 is adapted to the production line guide rail 3, it can move along the production line guide rail 3.

[0047] Please see Figures 6 to 7 Furthermore, the disc body 21 is provided with a lifting mold 211 and a docking joint 212. The lifting mold 211 is located at the edge of the disc body 21, and the docking joint 212 has a guide opening 213. The docking joint 212 is connected to the base plate 13 through the guide opening 213.

[0048] The lifting member 211 is used to activate when unloading is required after the support plate 131 is delivered to the accompanying tray 1. It reduces the friction of the support plate 131 on the disc 21 by air drive, making it easier to move. The guide port 213 is connected to the bottom plate 13 so that the relative position between the disc 21 and the support plate 131 is fixed.

[0049] Furthermore, the lifting member 211 includes a housing 214, a plurality of spherical bodies 215, and a connecting plate 216. The housing 214 has a strip-shaped structure, and the plurality of spherical bodies 215 are distributed along the length extension direction of the housing 214, and the plurality of spherical bodies 215 are movably fitted with the housing 214. The connecting plate 216 connects the plurality of spherical bodies 215 and is disposed inside the housing 214.

[0050] In this embodiment, the housing 214 is mounted on the disc 21, and its upper surface is provided with a plurality of spherical bodies 215. After the fixed fixture 4 is transferred from the mold changing trolley 2 to the production line guide rail 3, the spherical bodies 215, due to their load-bearing capacity, cause the connecting plate 216 to fall naturally. The fixed fixture 4 can contact the disc 21 relatively stably. After the workpiece is processed, gas is injected into the movable cavity 217 through the gas channel 219. Under the action of the pressurized gas, the connecting plate 216 drives the spherical bodies 215 to rise until they contact the bearing plate 131 and lift the bearing plate 131. The contact area between the bearing plate 131 and the spherical bodies 215 is reduced, which reduces the friction force when unloading the bearing plate 131 from the production line guide rail 3.

[0051] Furthermore, the housing 214 is provided with a movable cavity 217, and the top of the movable cavity 217 is provided with a plurality of movable holes 218, which correspond one-to-one with the spherical body 215. The movable cavity 217 is also connected to a gas channel 219, which is distributed at both ends of the movable cavity 217.

[0052] The movable cavity 217 mainly cooperates with the movement of the connecting plate 216. The gas channel 219 is used to input pressurized gas from the outside. The movable hole 218 is used to limit the maximum lifting height of the spherical body 215 when the spherical body 215 is lifted, so that the spherical body 215 is slightly higher than the disc body 21 under the action of pressurized gas, thereby lifting the fixed fixture 4.

[0053] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
