Description

Technical Field

[0001] This utility model relates to the field of automatic rubber ring assembly technology, specifically to an internal groove rubber ring assembly machine. Background Technology

[0002] In industrial production, the assembly of internal grooved rubber rings is a crucial step in the manufacturing and maintenance of many mechanical equipment. These rings need to be precisely installed into specific grooves within the workpiece to achieve functions such as sealing and vibration damping. This is especially true for the assembly of rubber rings inside caliper housings, such as... Figure 6 As shown, a rubber ring inlet 8 is provided on the caliper housing, and a groove 31 for installing the rubber ring 32 is provided inside the rubber ring inlet 8. However, the traditional internal groove rubber ring assembly method has many drawbacks.

[0003] On the one hand, manual assembly is inefficient and requires a high level of skill from workers, which is time-consuming and labor-intensive, and also results in high labor costs and low efficiency.

[0004] On the other hand, some existing assembly equipment is structurally inadequate. For example, some equipment cannot effectively guide the rubber ring smoothly into the workpiece's rubber ring inlet, and lacks a mechanism for controlling the rubber ring's posture during assembly. During the process of pressing the rubber ring down from its placement position into the workpiece groove, the rubber ring is prone to displacement and deformation due to uneven forces, making it unreliable for installation into the workpiece's inner groove and failing to meet the demands of modern large-scale, high-precision production. Therefore, developing an assembly device that can efficiently and accurately complete the assembly of inner groove rubber rings, avoiding tilting and twisting problems during assembly, is of significant practical importance. Utility Model Content

[0005] In view of the shortcomings of the prior art, this utility model provides an internal groove rubber ring assembly machine.

[0006] The technical solution adopted by this utility model is: an internal groove rubber ring assembly machine, comprising:

[0007] The support includes a base plate and upright plates fixed to the base plate;

[0008] A workpiece pallet, wherein a guide cylinder is provided on the workpiece pallet, and a tapered hole with a larger diameter at the top and a smaller diameter at the bottom is provided on the inner wall of the guide cylinder;

[0009] A fixing fixture is provided on the base plate below the guide cylinder for fixing the workpiece being processed. The bottom of the tapered hole is directly connected to the rubber ring inlet of the workpiece.

[0010] A pallet power mechanism is used to drive the workpiece pallet to move up and down along the height direction of the vertical plate.

[0011] An assembly mechanism, comprising an assembly power mechanism and a mounting head connected to the assembly power mechanism, wherein the assembly power mechanism drives the mounting head to move away from or towards the workpiece tray.

[0012] The mounting head includes a column, a positioning rod, an elastic element, and multiple support blocks. One end of the column has several equally spaced mounting grooves and spring grooves on its outer circumference. The positioning rod and the elastic element are respectively installed in the mounting grooves and spring grooves. The multiple support blocks are equally spaced on the outer circumference of the column, and each support block has a horizontal working surface at its lower end. The outer wall of each support block has a tapered surface that is smaller at the bottom and larger at the top, and the inner wall of each support block has a connecting portion. The connecting portion has a sliding groove that slides with the positioning rod. The elastic element has an elastic force that pulls the support block away from the column.

[0013] Furthermore, a spring hole is provided on the inner wall of the support block, and one end of the elastic element is connected to the spring groove, and the other end is connected to the spring hole.

[0014] Furthermore, a sliding plate is also connected to the workpiece pallet. The sliding plate slides with the upright plate through a slide rail slider assembly, and the output end of the pallet power mechanism is connected to the sliding plate.

[0015] Furthermore, a connecting plate is connected to the upper end of the column, and a second sliding plate is connected to one end of the connecting plate. The second sliding plate slides with the first sliding plate through a slide rail slider assembly. The assembly power mechanism is fixed to the bottom of the workpiece support plate, and the output end of the assembly power mechanism is connected to the second sliding plate.

[0016] Furthermore, both the workpiece support plate and the connecting plate are provided with an adjustable clamping structure, which includes a connecting hole, a slot, and a screw hole. The connecting hole can be tightened or loosened by connecting bolts to the screw hole.

[0017] Furthermore, it also includes a tooling power mechanism, wherein the fixed tooling is a sliding column flexible clamp, and a tooling base plate is provided at the bottom of the fixed tooling. The tooling base plate is slidably engaged with the base plate through a slide rail slider assembly, and the output end of the tooling power mechanism is connected to the tooling base plate.

[0018] The beneficial effects of this utility model are:

[0019] 1. Improved assembly efficiency: The pallet power mechanism can automatically drive the workpiece pallet to move up and down along the height of the vertical plate. The assembly power mechanism drives the mounting head to move closer to or away from the workpiece pallet. The mounting head uses the guide cylinder to smoothly press the rubber ring into the rubber ring inlet of the workpiece until it is stuck in the groove of the rubber ring inlet. The entire assembly process is automated, which greatly saves time and significantly improves production efficiency compared with manual assembly, meeting the needs of modern large-scale production.

[0020] 2. Improved Assembly Accuracy: The mounting head comprises a column, positioning rod, elastic element, and multiple support blocks working in tandem. The lower ends of the support blocks have horizontal working surfaces. During the downward pressing of the mounting head, the support blocks gradually contract along with the tapered hole of the guide cylinder. The horizontal working surfaces at the bottom of the support blocks ensure that the rubber ring remains in contact with the inner wall of the tapered hole during its descent, guaranteeing that the rubber ring is in a horizontal and flat downward state. Taking the assembly of the rubber ring inside the caliper housing as an example, this effectively prevents tilting and twisting when the rubber ring enters the rubber ring inlet, allowing the rubber ring to be accurately and reliably installed into the groove of the workpiece. This greatly improves assembly accuracy, thereby ensuring the sealing and vibration damping performance of the mechanical equipment, and improving overall quality and stability.

[0021] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0030] This utility model provides an internal groove rubber ring assembly machine.

[0031] In this embodiment, refer to Figure 1-5 The internal groove rubber ring assembly machine includes:

[0032] The support includes a base plate 1 and an upright plate 2 fixed on the base plate 1;

[0033] The workpiece support plate 3 is provided with a guide cylinder 4, and the inner wall of the guide cylinder 4 is provided with a tapered hole 5 with a larger diameter at the top and a smaller diameter at the bottom.

[0034] Fixture 6 is set on the base plate below the guide cylinder and is used to fix the workpiece 7 to be processed. The bottom of the tapered hole is directly connected to the rubber ring inlet 8 of the workpiece 7.

[0035] The pallet power mechanism 33 is used to drive the workpiece pallet to move up and down along the height direction of the vertical plate.

[0036] An assembly mechanism, comprising an assembly power mechanism 34 and an mounting head 9 connected to the assembly power mechanism, wherein the assembly power mechanism drives the mounting head to move away from or towards the workpiece tray.

[0037] The mounting head includes a column 10, a positioning rod 11, an elastic element 12, and multiple support blocks 13. One end of the column 10 has a plurality of mounting grooves 14 and spring grooves 15 evenly spaced around its outer circumference. The positioning rod 11 and the elastic element 12 are respectively installed in the mounting grooves and spring grooves. The multiple support blocks are evenly spaced around the outer circumference of the column, and each support block has a horizontal working surface 16 at its lower end. The outer wall of each support block has a tapered surface 17 that is smaller at the bottom and larger at the top. A connecting portion 18 is provided on the inner wall of each support block 13. The connecting portion 18 has a sliding groove 19 that slides with the positioning rod. The elastic element has an elastic force that pulls the support block away from the column.

[0038] In the above technical solution, the bracket provides a supporting foundation for the entire assembly machine, with the base plate placed securely and the vertical plate fixed for installing other components. The guide cylinder on the workpiece pallet has a tapered hole on its inner wall that guides the rubber ring gradually closer to the workpiece rubber ring inlet. A fixing fixture secures the workpiece being processed (such as a caliper housing), ensuring stable workpiece position during assembly. The pallet power mechanism drives the workpiece pallet to move up and down along the height of the vertical plate, adjusting the workpiece's vertical position. In the assembly mechanism, the assembly power mechanism drives the mounting head closer to or away from the workpiece pallet. The outer circumference of the mounting head's cylindrical body is equipped with mounting grooves and spring grooves, where positioning rods and elastic elements are respectively installed. Multiple support blocks are spaced apart on the outer circumference of the cylindrical body. The support blocks slide with the positioning rods through sliding grooves in the connecting parts, and the elastic elements provide the force to push the support blocks outward. When the mounting head is pressed down, the support blocks retract along the tapered hole, simultaneously ensuring the rubber ring moves horizontally downward.

[0039] By adopting the above technical solutions, the assembly of internal grooved rubber rings is automated, improving assembly efficiency. The structure of the mounting head ensures that the rubber ring remains horizontal during assembly, smoothly entering the groove of the workpiece. This effectively avoids tilting or twisting of the rubber ring, improves assembly accuracy, guarantees the installation quality of the rubber ring, and thus ensures the performance of the mechanical equipment.

[0040] In practical use, first, the workpiece to be processed is placed on the fixed fixture, which is installed on the base plate below the guide cylinder. The fixture is used to stabilize the position of the workpiece, and at the same time, the tapered hole of the guide cylinder is aligned with the rubber ring inlet of the workpiece.

[0041] Then, the rubber ring is placed inside the guide cylinder of the workpiece tray. The tapered hole on the inner wall of the guide cylinder is wider at the top and narrower at the bottom, which can guide the rubber ring downward.

[0042] The assembly mechanism begins operation, with the assembly power mechanism pushing the mounting head closer to the workpiece support plate. The mounting head consists of a column, a positioning rod, an elastic element, and multiple support blocks. The elastic element on the column pushes the support blocks away from the column, and the support blocks slide against the positioning rod through a sliding groove in the connecting part. During the downward pressing of the mounting head, the conical surface of the outer wall of the support block contacts the inner wall of the guide cylinder. As the inner diameter of the guide cylinder decreases, the support block contracts, and its lower horizontal action surface always ensures that the rubber ring descends horizontally until it is pressed from the conical hole into the rubber ring inlet of the workpiece, where it is installed into the groove by the elasticity of the rubber ring.

[0043] Specifically, the inner wall of the support block is provided with a spring hole 20, one end of the elastic element is connected to the spring groove, and the other end is connected to the spring hole 20.

[0044] In this embodiment, a spring hole is provided on the inner wall of the support block. One end of the elastic element is connected to the spring groove on the column, and the other end is connected to the spring hole of the support block. This connection method allows the elastic element to apply an outward elastic force to the support block more stably. During the pressing down of the mounting head, when the support block contracts within the tapered hole, the elastic force of the elastic element acts more reliably, maintaining the contact state between the support block and the rubber ring.

[0045] Specifically, the workpiece pallet is also connected to a slide plate 21, which slides with the upright plate through a slide rail slider assembly 22, and the output end of the pallet power mechanism is connected to the slide plate 21.

[0046] In this embodiment, the workpiece pallet is connected to the slide plate, and the slide plate and the upright plate are slidably engaged through a slide rail slider assembly. The output end of the pallet power mechanism is connected to the slide plate. When the pallet power mechanism is working, its power is transmitted to the slide plate through the output end. Due to the guiding effect of the slide rail slider assembly, the slide plate drives the workpiece pallet to make a smooth lifting and lowering motion along the height direction of the upright plate.

[0047] The slide rail and slider assembly of this application includes a slide rail and a slider, which are conventional components in the field of automation and can be purchased directly or customized.

[0048] Specifically, a connecting plate 23 is connected to the upper end of the column, and a sliding plate 24 is connected to one end of the connecting plate 23. The sliding plate 24 slides with the sliding plate 1 through a sliding rail slider assembly. The assembly power mechanism is fixed to the bottom of the workpiece tray, and the output end of the assembly power mechanism is connected to the sliding plate 2.

[0049] In this embodiment, a connecting plate is connected to the upper end of the column, and a second sliding plate is connected to one end of the connecting plate. The second sliding plate and the first sliding plate are slidably engaged through a slide rail slider assembly. The assembly power mechanism is fixed to the bottom of the workpiece support plate, and its output end is connected to the second sliding plate. After the assembly power mechanism is started, its output force pushes the second sliding plate. Under the action of the slide rail slider assembly, the second sliding plate slides relative to the first sliding plate, thereby driving the mounting head closer to or away from the workpiece support plate, realizing precise position adjustment of the mounting head.

[0050] Specifically, both the workpiece support plate and the connecting plate are equipped with an adjustable clamping structure, which includes a connecting hole 25, a slot 26 and a screw hole 27. The connecting hole can be tightened or loosened by connecting bolts to the screw hole.

[0051] In this embodiment, the adjustable clamping structure on the workpiece support plate and the connecting plate has a connecting hole for placing the component that needs to be fixed. The slotting allows the connecting hole to have a certain elastic deformation capability. The bolt is connected to the screw hole. By tightening or loosening the bolt, the connecting hole is tightened or loosened, thereby achieving the clamping or loosening of the component.

[0052] Specifically, it also includes a tooling power mechanism 28. The fixed tooling is a sliding column flexible clamp. The bottom of the fixed tooling is provided with a tooling base plate 29. The tooling base plate is slidably engaged with the base plate through a slide rail slider assembly. The output end of the tooling power mechanism is connected to the tooling base plate.

[0053] In this embodiment, the tooling power mechanism is connected to the tooling base plate. The fixed tooling is a sliding column flexible clamp mounted on the tooling base plate, and the tooling base plate is slidably engaged with the base plate via a slide rail slider assembly. When the tooling power mechanism is working, it drives the tooling base plate to slide on the base plate, thereby moving the fixed tooling and adjusting the position of the workpiece being processed.

[0054] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
