Description

Technical Field

[0001] This invention relates to a synchronous installation fixture, and more particularly to a synchronous installation fixture for vacuum hose quick-connect fittings and clamps, belonging to the field of automotive parts manufacturing. Background Technology

[0002] With a substantial annual sales volume, the production of various automotive parts is also extremely demanding. Vacuum hoses are crucial automotive components, with numerous specifications and complex installation processes. Quick-connect fittings and clamps are some of the installation parts on vacuum hoses (along with the installation of other parts such as retainers and brackets). In conventional production, the quick-connect fitting is usually inserted first, and then the clamp is fitted onto the other end to tighten it. However, this process is inefficient when the vacuum hose is curved. Alternatively, the clamp can be fitted first (with some misalignment, otherwise the quick-connect fitting would be difficult to insert), and then the clamp is moved to the final installation position and tightened after the quick-connect fitting is in place. Summary of the Invention

[0003] Purpose of the invention: The purpose of this invention is to provide a tooling for the simultaneous installation of quick-connect fittings and clamps on vacuum hoses.

[0004] Technical solution: The vacuum hose quick-connect and clamp synchronous installation fixture of the present invention includes a base plate, a hose fixing device, a quick-connect installation device and a clamp installation device;

[0005] The quick-connect installation device includes a quick-connect conveying groove vertically disposed on one side of the hose fixing device and a quick-connect pushing cylinder disposed at the bottom of the other side of the quick-connect conveying groove; several quick-connects are arranged side by side in the quick-connect conveying groove, and the lowest quick-connect is coaxial with the hose socket fixed by the hose fixing device.

[0006] The clamp installation device includes a clamp installation main component, a clamp delivery conduit, a clamp pushing cylinder, and a pushing slider, all located between the hose fixing device and the quick-connect installation device. The upper surface of the clamp installation main component has a horizontal guide groove. The width of the guide groove is the same as the axial length of the clamp, and the length direction of the guide groove is perpendicular to the axis of the fixed hose. The pushing slider is slidably disposed within the guide groove, and its rear end is connected to the piston rod of the clamp pushing cylinder. The clamp delivery conduit delivers the clamp into the guide groove. When the pushing slider pushes the clamp to the end baffle of the guide groove, the clamp and the fixed hose connector are coaxial.

[0007] Furthermore, the clamp is a metal elastic element, with a first pin and a second pin extending from the lower end of the clamp. When the first pin and the second pin are clamped and the gap is compressed by the clamp, the clamp opens. The front end of the push slider is provided with an arc groove that matches the outer circle of the clamp in the open state, and the height of the arc groove axis is consistent with the height of the axis of the fixed hose. Below the arc groove is a jaw, which, together with the end baffle at the end of the guide groove, forms a pair of clamps. When the push slider pushes the clamp to the end baffle, the jaw and the end baffle clamp the first pin and the second pin of the clamp, causing the clamp to open.

[0008] Furthermore, an ear plate for connecting the clamp delivery conduit is provided on one side of the middle of the guide groove, and a first notch for the clamp to pass through is provided on the ear plate. A side baffle is provided on the other side of the middle of the guide groove.

[0009] Furthermore, the clamp delivery conduit is composed of three sections: a long conduit section extending upwards, a short straight conduit section in a horizontal position, and an arc-shaped connecting conduit section between the two sections; the end of the short straight conduit section in the horizontal position is provided with a connecting plate, and the clamp delivery conduit is connected to the ear plate through the connecting plate; the clamp delivery conduit has a C-shaped cross-section with the opening facing downwards, and the clamps are slidably arranged inside the clamp delivery conduit, with the first and second pins of the clamps extending out of the clamp delivery conduit through the opening groove at the C-shaped opening;

[0010] The push slider extends forward under the action of the clamp push cylinder. The clamp located in the arc groove slides forward along the guide groove until the first pin is blocked by the end baffle. The push slider continues to move forward a little. At this time, the jaws push the second pin forward. The first pin and the second pin are squeezed together, and the clamp opens. At this time, the clamp is coaxial with the fixed hose. A baffle is provided on the side of the push slider near the ear plate to prevent the clamp in the clamp delivery tube from entering the guide groove when the push slider pushes the clamp forward. When the push slider retracts to the initial position under the action of the clamp push cylinder, the clamp in the clamp delivery tube moves downward and horizontally under the action of gravity. It enters the guide groove in sequence through the first notch and the second notch and is limited by the side baffle.

[0011] Furthermore, a top baffle is provided above the arc groove.

[0012] Furthermore, the hose fixing device includes: a support frame consisting of a bottom plate, a top plate parallel to the bottom plate, and a middle vertical plate, disposed on the base plate, and a fixed pressure block and a moving pressure block fixed on the bottom plate; the opposing surfaces of the fixed pressure block and the moving pressure block are provided with semi-circular grooves with an inner diameter the same as the outer diameter of the vacuum hose.

[0013] Furthermore, the hose fixing device also includes a guide rail slider assembly vertically fixed to the inner side of the upright plate and a pressing cylinder disposed on the top plate; the piston rod of the pressing cylinder passes downward through the top plate of the first bracket and is fixedly connected to the moving pressure block, the moving pressure block is connected to the slider of the guide rail slider assembly, and the piston rod of the pressing cylinder pushes the moving pressure block to move downward to cooperate with the fixed pressure block to press the hose.

[0014] Furthermore, the lower end of the quick-connect insertion conveyor channel is fixedly connected to the substrate via a conveyor channel fixing seat.

[0015] Furthermore, a quick-connect push rod is fixed on the piston rod of the quick-connect push cylinder, and the quick-connect push rod and the fixed hose connector are coaxial.

[0016] Furthermore, the piston rod of the push cylinder extends axially, pushing the quick-connect insert out axially from the quick-connect insert conveying groove and inserting the small end of the quick-connect insert into the hose hole; the piston rod retracts back to its original position, and the quick-connect insert in the quick-connect insert conveying groove moves downward under the action of gravity to feed, waiting for the next installation process.

[0017] Beneficial effects: Compared with the prior art, the present invention can complete the installation of quick-connect plugs and clamps simultaneously in one go, which improves production efficiency; the tooling structure is simple, reducing investment costs and improving reliability.

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings and embodiments.

[0032] As attached Figure 1 and attached Figure 2 As shown, the vacuum hose quick-connect and clamp synchronous installation fixture described in this embodiment mainly includes a base plate 1, a hose fixing device 2, a quick-connect installation device 3, and a clamp installation device 4.

[0033] The substrate 1 is set horizontally, and the hose fixing device 2, quick plug installation device 3, and clamp installation device 4 are all fixedly installed on the substrate 1.

[0034] As attached Figure 3 The hose fixing device 2 is fixedly installed on the base plate 1 by the bracket 21.

[0035] The support frame 21 consists of a lower horizontal base plate, an upper horizontal top plate, and vertical plates.

[0036] The pressure regulating block 22 is fixedly mounted on the horizontal base plate of the bracket 21, and a semi-circular groove matching the outer diameter of the hose is provided on the pressure regulating block 22.

[0037] The guide rail of the guide rail slider assembly 24 is vertically fixed inside the upright plate of the bracket 21.

[0038] The moving pressure block 23 is fixedly connected to the slider. A semi-circular groove matching the outer diameter of the hose is provided horizontally on the lower part of the moving pressure block 23.

[0039] (Cylinder 1) The clamping cylinder 25 is vertically fixed on the horizontal top plate of the bracket 21. The piston rod of the clamping cylinder 25 passes through the through hole on the top plate, and the lower end of the piston rod is fixedly connected to the dynamic pressure block 23.

[0040] The piston rod of the clamping cylinder 25 pushes the moving pressure block 23 downward to cooperate with the fixed pressure block 22 to clamp the hose 5.

[0041] The quick-connect installation device 3 is located on one side of the hose fixing device 2, as shown in the attached figure. Figure 1 and attached Figure 2 The quick-installation device 3 consists of a conveyor belt fixing base 31, a quick-installation conveyor belt 32, a quick-installation push cylinder (cylinder two) 33, and a quick-installation push rod 34, as shown in the attached diagram. Figure 4 .

[0042] The quick-connect conveyor 32 is set vertically, and its lower end is fixedly connected to the base plate 1 through the conveyor trough fixing seat 31.

[0043] The structure of Quick Plugin 6 is attached. Figure 12 .

[0044] The quick-connect inserts 6 are horizontally positioned and arranged vertically in parallel, sliding within the guide groove of the quick-connect insert conveying groove 32. The centerline of the lowest quick-connect insert 6 is coaxial with the centerline of the semi-circular groove on the pressure block 22, and the small end of the quick-connect insert 6 points towards the pressure block 22.

[0045] (Cylinder Two) The quick-connect insert pushing cylinder 33 is located outside the quick-connect insert conveying groove 32, and its piston rod end is fixedly equipped with a quick-connect insert pushing rod 34. The small end of the pushing rod 34 mates with the center hole of the quick-connect insert 6. The axis of the pushing rod 34 is coaxial with the center line of the semi-circular groove on the pressure block 22.

[0046] The piston rod of the push cylinder 33 extends axially, and the small end of the push rod 34 is inserted into the center hole of the quick insert located at the bottom of the conveying groove 32, pushing the quick insert axially out of the conveying groove 32 and inserting the small end of the quick insert into the hose hole; the piston rod drives the push rod 34 to return to its original position, and the quick insert in the conveying groove 32 moves downward under the action of gravity to feed, waiting for the next quick insertion process.

[0047] Clamp 7 is a metal elastic component; its structure is shown in the attached diagram. Figure 11 Pinch both ends of the clamp with calipers. When the distance between one end 71 and the other end 72 of the clamp decreases, the clamp will open.

[0048] Clamp installation device 4, as shown in the attached document Figure 5 It is fixedly installed on the base plate 1, located between the hose fixing device 2 and the quick-connect installation device 3, on the side closer to the hose fixing device 2. The clamp installation device 4 consists of a clamp delivery conduit 41, a clamp installation main component 42, a push slider 43, and a (cylinder three) clamp push cylinder 44.

[0049] The clamp mounting main component 42 is fixedly mounted on the base plate, on the side near the hose fixing device 2.

[0050] As attached Figure 8The clamp mounting main component 42 has a horizontal guide groove 421 on its upper surface, the width of which matches the axial length of the clamp. The length direction of the guide groove 421 is perpendicular to the axis of the semi-circular groove on the pressure block 22. The end of the guide groove 421 is provided with an end baffle 422 as a fixed jaw.

[0051] A lug 423 for fixing the connecting clamp conveying conduit 41 is fixedly provided on one side of the guide groove 421, and a notch 424 for the clamp to pass through is provided on the lug 423.

[0052] A side baffle 425 is fixedly provided on the other side of the guide groove 421 to limit the axial position of the clamp.

[0053] As attached Figure 7 The push slider 43 is fixedly mounted on the piston rod 441 end of the clamp push cylinder 44 (cylinder three), and slidably mounted within the guide groove 421. The initial position of the push slider 43 is located at the starting end of the guide groove 421, as shown in the attached figure. Figure 6 As shown.

[0054] As attached Figure 9 The front end of the push slider 43 is provided with an arc groove 431 that matches the outer circle of the clamp in the open state. In the assembled state, the axial height of the arc groove 431 is consistent with the axial height of the semi-circular groove on the pressure block 22.

[0055] A movable jaw 432 is provided below the arc groove 431. The jaw 432 and the fixed jaw 422 at the end of the guide groove 421 form a pair of jaws, which are used to clamp the two ends of the clamp and open the clamp.

[0056] A top plate 433 is provided above the arc groove 431 to prevent the clamp from rolling and moving when pushed by the push slider 43.

[0057] A baffle 434 is fixedly provided on the side of the push slider 43 near the ear plate 423 to prevent the clamp in the clamp delivery conduit 41 from entering the guide groove 421 when the push slider 43 pushes the clamp forward.

[0058] Clamp delivery conduit 41, as attached Figure 10 It consists of three sections: a long, upward-extending conduit section, a short, straight conduit section positioned horizontally at the bottom, and an arc-shaped connecting conduit section between the two sections. The clamp delivery conduit 41 is fixedly connected to the ear plate 423 via a connecting plate 412 at its lower end. The conduit cross-section is C-shaped, with the opening facing downwards. The clamps are slidably arranged inside the conduit 41, with both ends of the clamps (clamp end 71 and clamp end 72) extending out of the conduit 41 through guide groove 1 411. Under the force of gravity, each clamp within the upward-extending long conduit section moves downwards and horizontally, sequentially entering guide groove 2 421 through notch 1 413 and notch 2 424, and is limited by the side baffle 425.

[0059] The push slider 43 extends forward under the action of the clamp push cylinder 44 (cylinder three). The clamp located in the arc groove 431 slides forward along the guide groove 421 until one end 71 of the clamp is blocked by the end baffle (fixed jaw) 422. The push slider 43 continues to move forward a little. At this time, the moving jaw 432 pushes the other end 72 of the clamp forward. Both ends of the clamp are squeezed and the clamp opens (the inner hole expands). At this time, the axis of the clamp is coaxial with the center line of the semi-circular groove on the fixed pressure block 22.

[0060] The working process of this embodiment is as follows:

[0061] Initially, the dynamic pressure block 23 of the hose fixing device 2 is in the high position, the push slider 43 of the clamp installation device 4 is in the initial position, and the quick plug push rod 34 is in the retracted initial position.

[0062] First, the push slider 43 extends forward under the action of the clamp push cylinder 44 (cylinder three). The clamp located in the arc groove 431 slides forward along the guide groove 421 until one end 71 of the clamp is blocked by the end baffle (fixed jaw) 422. The push slider 43 continues to move forward a little. At this time, the moving jaw 432 pushes the other end 72 of the clamp forward. Both ends of the clamp are squeezed and the clamp opens (the inner hole expands). At this time, the axis of the clamp is coaxial with the center line of the semi-circular groove on the fixed pressure block 22.

[0063] Place the hose into the semi-circular groove of the pressure block 22 of the hose fixing device 2, and make the hose extend axially into the expanded clamp (the axial position of the hose is limited by the limiting block, which is not shown in the figure).

[0064] (Cylinder 1) When the clamping cylinder 25 is activated, the moving pressure block 23 moves down to clamp the hose;

[0065] The piston rod of the push cylinder 33 extends axially, and the small end of the push rod 34 is inserted into the center hole of the quick insert located at the bottom of the conveying groove 32, pushing the quick insert axially out of the conveying groove 32 and inserting the small end of the quick insert into the hose hole; the piston rod drives the push rod 34 to return to its original position, and the quick insert in the conveying groove 32 moves downward under the action of gravity to feed, waiting for the next quick insertion process.

[0066] Under the action of the clamp pushing cylinder 44 (cylinder three), the push slider 43 retracts to the initial position, and the clamp in the clamp conveying conduit 41 is pushed into the initial position, waiting for the next feeding.

[0067] (Cylinder 1) When the clamping cylinder 25 is activated, the moving pressure block 23 moves upward back to the high position, releasing the hose;

[0068] Remove the installed hose, as shown in the attached document. Figure 13 As shown.

[0069] Proceed to the next work cycle.

[0070] All of the above cylinder actions can be completed automatically and rapidly in sequence under program control.
