Description

Technical Field

[0001] The utility model relates to the technical field of feeding equipment, in particular to an automatic feeding device for a hydraulic end cover. Background Art

[0002] Hydraulic end caps used in hydraulic workpieces are generally annular in structure, with different docking components at each axial end, resulting in irregular shapes. Some hydraulic end caps even have a semi-circular protrusion on one end. After casting, hydraulic end caps require multiple precision machining steps, such as milling, drilling, and grinding.

[0003] During actual processing, due to their irregular shapes, hydraulic end caps are manually removed and placed into lathes to ensure they fit in a fixed position and angle for easy processing. This manual handling method is relatively backward, requiring a dedicated operator for each piece of equipment, resulting in low efficiency and high labor costs.

[0004] Therefore, it is necessary to design an automatic feeding device to enable the hydraulic end cover to accurately enter the predetermined work position with a fixed posture and angle, which is conducive to automatic clamping by the robotic arm, thereby improving work efficiency and reducing costs. Utility Model Content

[0005] The present invention provides an automatic feeding device for hydraulic end caps to solve the problems mentioned in the above background technology. It can realize automatic feeding of hydraulic end caps, allowing one worker to simultaneously monitor multiple lathes, saving a lot of labor costs and significantly improving work efficiency.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] An automatic feeding device for hydraulic end caps comprises a feeding track and workpieces fed one by one at the head and tail of the track;

[0008] A side support wall is provided below the discharge end of the feeding track and is located on one side of the feeding track. The side support wall is provided with at least two symmetrically arranged support arms for lifting the workpiece.

[0009] A lifting seat is provided below the support arm; the lifting seat is driven by the driving end of the driving component to move closer to or away from the feeding track; the lifting seat is provided with at least two symmetrically arranged blocking rods for laterally supporting the workpiece;

[0010] The feeding track is provided with side baffles arranged along the feeding direction thereof, and the side baffles are positioned in the height direction and the lateral direction in the feeding track through an adjustment mechanism.

[0011] Preferably, the adjustment mechanism includes an adjustment bracket fixed to the feed track, and the adjustment bracket and the feed track are respectively provided with corresponding long slot holes; the side baffle is provided with an adjustment screw with one end rotatably connected thereto, and the adjustment screw passes through the long slot hole; the adjustment screw is fastened to the adjustment bracket through an adjustment nut.

[0012] Preferably, the support arm has a cone structure.

[0013] Preferably, the lifting seat is provided with a plurality of evenly distributed plug holes 1, and the support arms are plugged into the plug holes 1.

[0014] Preferably, the side support wall is provided with a plurality of evenly distributed second plug-in holes, and the blocking rods are plugged into the second plug-in holes.

[0015] Preferably, the end surface of the feeding track is G-shaped.

[0016] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0017] The workpieces are conveyed one by one from head to tail in the feeding track, and the side baffles can be adapted and engaged with the raised stepped semicircular rings on the workpieces, thereby ensuring that the workpieces are conveyed in a fixed posture and angle in the feeding track.

[0032] In order to make the purpose, technical solutions and advantages of this utility model more clear, the following is a brief description of the invention. Figure 1 To the attached Figure 8 The present invention is further described in detail with reference to the following embodiments. However, it should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the scope of the present invention. In addition, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0033] This embodiment discloses an automatic feeding device for hydraulic end caps, comprising a feed track 200, within which workpieces 100 are fed one by one, one at each end. The feed track 200 has a G-shaped end surface with a notch running through one side. This structure allows workers to easily monitor the number of workpieces 100 through the notch, ensuring timely restocking.

[0034] The shape of the workpiece 100 can be referred to Figure 1 and Figure 2 The content shown has a special and irregular shape.

[0035] Of course, the feeding track 200 has a certain inclination angle so as to realize a natural sliding feeding state of the workpiece 100 under the action of gravity.

[0036] A side support wall 210 is provided on one side of the feeding track 200 below the discharge end of the feeding track 200 (i.e., the bottom end shown in the figure). The side support wall 210 is provided with at least two symmetrically arranged support arms 201 for lifting the workpiece 100. When the workpiece 100 is lifted by it, it can ensure that the workpiece 100 is stably located between the two support arms 201 and will not shift.

[0037] In addition, the support arm 201 is a cone-shaped structure, with the top of the cone facing the side support wall 210 and the bottom of the cone facing the opposite direction. This structure can ensure that the center of gravity of the workpiece 100 is stable when it is lifted and will not tilt. Specifically, some workpieces 100 have special and irregular shapes. When they are naturally lifted, they will tilt in the clamping direction due to the influence of their center of gravity. The support arm 201 can just use the tilted state of the surface to force the workpiece 100 to tilt in the opposite direction. Combined with the support of the side support wall 210, the workpiece 100 will be in a certain tilted posture when it is lifted (such as Figure 7 When the clamping device 400 is clamped, the workpiece 100 is clamped and restored to a vertical position, so that it can be neatly placed in the lathe station.

[0038] A lifting seat 301 is provided below the support arm 201; the lifting seat 301 is driven by the driving end of the driving component 300 to move closer to or away from the feeding track 200; the lifting seat 301 is provided with at least two symmetrically arranged blocking rods 302 for laterally supporting the workpiece 100, which can ensure that the workpiece 100 does not deviate when it falls from the feeding track, and play a limiting role together with the support arm 201.

[0039] The feeding track 200 is provided with a side baffle 204 arranged along its feeding direction, which can be adapted to be connected with the raised stepped semicircular ring on the workpiece 100, thereby ensuring that the workpieces 100 are transported one by one in the same posture.

[0040] In addition, the side baffle 204 is positioned in the height direction and the lateral direction within the feeding track 200 through an adjustment mechanism, so that it can adapt to the use of workpieces 100 of different specifications and sizes without replacing other feeding tracks.

[0041] As a further improvement to this embodiment, the adjustment mechanism includes a plurality of adjustment brackets 2044 fixedly connected to the feed track 200, preferably by welding. The adjustment brackets 2044 and the feed track 200 are respectively provided with corresponding elongated slots 2043, which are coaxially aligned with each other. The elongated slots 2043 are arranged vertically in the height direction to facilitate height adjustment of the side baffles 204.

[0042] The side baffle 204 is provided with an adjusting screw rod 2042 with one end rotatably connected thereto, and the adjusting screw rod 2042 passes through the long slot hole 2043 .

[0043] When the pitch adjustment screw 2042 rotates axially, it does not affect the posture of the side baffle 204. Moreover, the adjustment screw 2042 can also freely rotate axially within the long slotted hole 2043. The adjustment screw 2042 is fastened to the adjustment bracket 2044 via the adjustment nut 2041. In other words, the height and axial positioning of the adjustment screw 2042 are fixed to the adjustment bracket 2044 via the adjustment nut 2041. The two adjustment nuts 2041 are arranged on both sides of the adjustment bracket 2044 and are threadedly connected to each other to achieve the purpose of tightening the adjustment screw 2042, ultimately ensuring the fixed posture of the side baffle 204.

[0044] In order to adapt to workpieces 100 of different sizes, the lifting seat 301 is provided with a plurality of insertion holes 303 evenly distributed in the transverse direction. The support arm 201 realizes its own height positioning by plugging into the insertion holes 303 at different height positions, thereby adapting to workpieces 100 of different diameters.

[0045] In order to adapt to workpieces 100 of different specifications and sizes, the side support wall 210 is provided with a plurality of plug-in holes 202 evenly distributed in the vertical direction. The blocking rod 302 can be plugged into different plug-in holes 202 and can adapt to workpieces 100 of different lengths (i.e., the size of the workpiece 100 in the axial direction).

[0046] When in use, the workpieces 100 are placed one by one at the top of the feeding track 200. When placing, it is necessary to ensure that the raised stepped semicircular ring and the side baffle 204 are matched with each other, so as to ensure that the workpieces 100 are transported one by one in the same posture. The feeding track 200 itself has an inclination angle and a drop. At the bottom of the feeding track 200, at least one limit cylinder on one side is used to realize the drop of the workpieces 100 one by one (refer to Figure 3 ). That is, the workpiece 100 at the bottom falls alone, and the other workpieces 100 above it are in a waiting state due to the influence of the limiting cylinder.

[0047] When the workpiece 100 at the bottom is lifted by the support arm 201, it will be tilted at a certain angle to maintain the balance of its own center of gravity, and to facilitate the clamping device 400 to be inserted into its inner cavity to clamp and send it to the predetermined workstation of the lathe.

[0048] Due to the adoption of the above technical solution, the beneficial effects of the utility model are as follows:

[0049] The workpieces are conveyed one by one from head to tail in the feeding track, and the side baffles can be adapted and engaged with the raised stepped semicircular rings on the workpieces, thereby ensuring that the workpieces are conveyed in a fixed posture and angle in the feeding track.

[0050] Due to the special shape of the workpiece, when it is lifted on the support arm, it will tilt toward the clamping direction. The conical support arm can use the inclined surface to force the workpiece to tilt in the opposite direction to ensure the balance of the center of gravity, and will not affect the insertion of the clamping device into the inner cavity of the workpiece.

[0051] While the present invention has been described above with reference to exemplary embodiments, various modifications may be made and equivalent components may be substituted without departing from the scope of the present invention. In particular, as long as no structural conflicts exist, the various features of the disclosed embodiments may be combined with one another in any manner. The omission of an exhaustive description of these combinations in this specification is solely for the sake of space and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but encompasses all technical solutions within the scope of the claims.
