[0001] The utility model relates to the technical field of chamfering machines, and particularly relates to a chamfering machine for producing steel bar sleeves. Background Art
[0002] A chamfering machine is a small precision machine tool specialized for chamfering and deburring products processed by methods such as milling and planing in die manufacturing, hardware machinery, machine tool manufacturing, hydraulic parts, valve manufacturing, and textile machinery. Adopting rapid machine chamfering is the development trend of the machinery industry.
[0003] When using a chamfering machine to chamfer the end of a bushing-like part, a pneumatic elastic chuck is generally used to clamp the workpiece, which can achieve automatic clamping of the workpiece and automatic blanking. When blanking after processing, the chuck will automatically throw the workpiece, which will cause a certain impact when unloading the workpiece. When the workpiece falls, it will produce an impact, causing an impact on the surface of the workpiece and reducing its surface quality. Content of the Utility Model
[0004] The purpose of the utility model is to solve the above deficiencies and provide a chamfering machine for producing steel bar sleeves.
[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:
[0006] A chamfering machine for producing steel bar sleeves includes a workbench. A blanking port is opened on the workbench. A loading table is arranged at one end of the blanking port, and a clamping assembly is arranged at the other end of the blanking port. Tools are arranged on both sides of the blanking port. It further includes:
[0007] A loading assembly, arranged between the blanking port and the loading table, for putting the steel bar sleeve into the clamping assembly;
[0008] A buffer assembly, movably arranged in the blanking port, for buffering the steel bar sleeve.
[0009] Further, the buffer assembly includes a hydraulic cylinder located at the bottom of the blanking port. A lifting platform is arranged at the movable end of the hydraulic cylinder. A buffer plate is arranged at the top of the lifting platform. A deflection assembly is arranged between the buffer plate and the lifting platform.
[0010] Further, a stop bar is arranged on the inner side wall of the blanking port, and a limiting plate matched with the stop bar is arranged at one end of the buffer plate.
[0011] Further, the deflection assembly includes a column fixed on the lifting platform. The buffer plate is rotatably connected to the column. A rotating rod is arranged on one side of the lifting platform away from the column. The top end of the rotating rod is rotatably connected to the buffer plate, and the bottom end of the rotating rod is slidably connected to the lifting platform.
[0012] Further, a sliding rod is arranged inside the lifting table, a limiting sliding block is sleeved on the sliding rod, the bottom end of the rotating rod is rotatably connected to the limiting sliding block, and a limiting spring sleeved on the sliding rod is arranged on one side of the limiting sliding block.
[0013] Further, the feeding assembly includes a fixed head, a lifting rod slidably connected to the feeding table is arranged on one side of the fixed head, a fixed plate is arranged at the bottom end of the fixed head, a bidirectional threaded rod is rotatably arranged inside the fixed plate, and clamping plates sleeved on the bidirectional threaded rod are arranged at both ends of the fixed plate.
[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0015] In the present utility model, a buffer assembly is arranged inside the discharging port. When chamfering, the buffer plate is at the topmost end of the discharging port. After chamfering the reinforcing bar sleeve is completed, the clamping assembly releases, and the reinforcing bar sleeve falls onto the buffer plate. Then, the hydraulic cylinder drives the buffer plate to move downward. The limiting plate at the bottom of the buffer plate is sleeved on the blocking rod. Under the blocking of the blocking rod, the buffer plate deflects, so that the reinforcing bar sleeve moves towards the slideway, reducing the impact force generated when the workpiece drops.

Detailed Embodiments
[0022] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.
[0023] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative position relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.
[0024] Refer to Figures 1 - 4 As shown, a chamfering machine for producing steel bar sleeves includes a workbench 1. A blanking opening is provided on the workbench 1, and a slideway is also provided outside the blanking opening. After the steel bar sleeve falls into the blanking opening, it will slide out along the slideway. One end of the blanking opening is provided with a loading table 2, and the other end of the blanking opening is provided with a clamping assembly 4. Cutting tools 5 are provided on both sides of the blanking opening for chamfering the steel bar sleeve. It further includes:
[0025] A loading assembly 3 is arranged between the blanking opening and the loading table 2. The loading table 2 can send the steel bar sleeves into the loading assembly 3 one by one, and then through the loading assembly 3 into the clamping assembly 4;
[0026] A buffer assembly 6 is movably arranged in the blanking opening. When chamfering the steel bar sleeve, the buffer assembly 6 is at the top of the blanking opening. In this way, when the steel bar sleeve falls, it will first fall on the buffer assembly 6 for buffering the steel bar sleeve.
[0027] In one embodiment, the buffer assembly 6 includes a hydraulic cylinder 61 at the bottom of the blanking opening. The movable end of the hydraulic cylinder 61 is provided with a lifting platform 62. A buffer plate 63 is arranged on the top of the lifting platform 62. The buffer plate 63 itself has a certain elasticity, mainly to buffer the steel bar sleeve when it falls. A deflection assembly 64 is arranged between the buffer plate 63 and the lifting platform 62;
[0028] After the steel bar sleeve is chamfered, it falls on the buffer plate 63. At this time, the hydraulic cylinder 61 drives the lifting platform 62 to descend. When the buffer plate 63 approaches the slideway, the deflection assembly 64 can drive the buffer plate 63 to deflect towards the slideway, generating an inclination, so as to facilitate the movement of the steel bar sleeve towards the slideway and finally slide out from the slideway.
[0029] In one embodiment, a stop bar 11 is provided on the inner side wall of the blanking opening, and a limiting plate 631 that cooperates with the stop bar 11 is provided at one end of the buffer plate 63;
[0030] When the buffer plate 63 moves downward, the limiting plate 631 will be sleeved on the stop bar 11. At this time, when the buffer plate 63 continues to move downward, the buffer plate 63 will deflect under the obstruction of the stop bar 11.
[0031] In one embodiment, the deflection assembly 64 includes a column 641 fixed to the lifting platform 62. The column 641 is on the side away from the limiting plate 631. The buffer plate 63 is rotatably connected to the column 641. A rotating rod 642 is provided on the side of the lifting platform 62 away from the column 641. The top end of the rotating rod 642 is rotatably connected to the buffer plate 63, and the bottom end of the rotating rod 642 is slidably connected to the lifting platform 62;
[0032] When the buffer plate 63 moves downward, the limiting plate 631 is sleeved on the stop bar 11, so that the side of the buffer plate 63 close to the limiting plate 631 is blocked. When the buffer plate 63 continues to move downward, the buffer plate 63 will tilt, that is, the end close to the column 641 moves downward and deflects, while the end close to the limiting plate 631 is still at a high position, generating an inclination towards the slideway direction, which is convenient for the steel bar sleeve to slide off.
[0033] In one embodiment, a sliding rod 621 is provided in the lifting platform 62. A limiting slider 622 is sleeved on the sliding rod 621. The bottom end of the rotating rod 642 is rotatably connected to the limiting slider 622. A limiting spring 623 sleeved on the sliding rod 621 is provided on one side of the limiting slider 622;
[0034] When the buffer plate 63 moves downward and tilts, the buffer plate 63 will pull the rotating rod 642, causing the rotating rod 642 to deflect. Moreover, the rotating rod 642 compresses the limiting spring 623 through the limiting slider 622. When the buffer plate 63 rises, the buffer plate 63 can return to the initial horizontal state under the elastic force of the limiting spring 623.
[0035] In one embodiment, the feeding assembly 3 includes a fixed head 31. A lifting rod 32 that is slidably connected to the feeding table 2 is provided on one side of the fixed head 31. A fixing plate 33 is provided at the bottom end of the fixed head 31. A bidirectional threaded rod 35 is rotatably provided in the fixing plate 33. Clamping plates 34 sleeved on the bidirectional threaded rod 35 are provided at both ends of the fixing plate 33. The driving sources of the lifting rod 32 and the bidirectional threaded rod 35 both come from a small motor.
[0036] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-mentioned exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be embraced within the present utility model.
