Description

Technical Field

[0001] The utility model relates to the technical field of metal casting processing, in particular to a metal casting feeding device. Background Art

[0002] Castings are metal shaped objects obtained by various casting methods, that is, the smelted liquid metal is poured into a pre-prepared mold by pouring, injection, suction or other casting methods, and then cooled and polished to obtain objects with a certain shape, size and performance.

[0003] During the production process, metal castings need to go through a series of processing equipment for processing and forming. Between adjacent processing stations, separate robots are usually set up to connect the adjacent stations. With more stations, the number of robots set up will also increase, which undoubtedly increases the processing cost. Moreover, when multiple groups of robots work together, the continuity of the connection is poor, which easily affects the processing efficiency.

[0004] Therefore, a metal casting feeding device is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the prior art, the utility model provides a metal casting feeding device, which has the advantages of low cost and better continuity during feeding. It solves the problem that there are more workstations and the number of robots will increase, which will undoubtedly increase the processing cost, and when multiple groups of robots work together, the continuity of the connection is poor, which easily affects the processing efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a metal casting feeding device, comprising a processing table, on which are provided three groups of clamping and feeding mechanisms arranged at equal distances and a pushing mechanism at the tail end;

[0007] The clamping and feeding mechanism comprises a support frame, on which a pair of clamping cylinders capable of moving up and down are arranged, two adjacent support frames are connected by a long connecting plate, a driving cylinder is fixed on the processing table, and an output shaft of the driving cylinder is fixed to the rightmost support frame;

[0008] The material pushing mechanism comprises a pair of support rods, and a material pushing seat which can move linearly forward and backward is arranged above the pair of support rods.

[0009] Furthermore, a pair of lifting cylinders are fixed on the support frame, and the output shafts of the lifting cylinders are fixed to a lifting frame that performs linear up and down motion on the support frame, and the fixed end of the clamping cylinder is fixed to the front side of the lifting frame.

[0010] Furthermore, a vertically arranged guide slider is fixed on the support frame, and a guide rail corresponding to the guide slider is fixed on the support frame.

[0011] Furthermore, a limiting slide rail is fixed on the top surface of the processing table, and a limiting sliding block slidably connected to the limiting slide rail is fixed on the bottom surface of the support frame.

[0012] Furthermore, a pair of support seats are fixed on the processing table, and a pair of support rods are commonly fixed on the support seats.

[0013] Furthermore, a linear module is fixed on the processing table, and the pusher seat is fixed to the output end of the linear module.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The metal casting feeding device has a long connecting plate that connects the support frames in adjacent clamping and feeding mechanisms, which can be extended and retracted through the same driving cylinder to control the simultaneous movement of three groups of clamping and feeding mechanisms. The three groups of clamping and feeding mechanisms cooperate more smoothly, allowing the three groups of clamping and feeding mechanisms to feed the workpieces in an orderly manner, thereby improving the continuity of workpiece processing.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 A metal casting feeding device in this embodiment includes a processing table 1, on which are provided three groups of clamping and feeding mechanisms 2 arranged equidistantly and a pushing mechanism 3 located at the tail end. The three groups of clamping and feeding mechanisms 2 can move left and right at the same time, so that the workpiece of the previous station can be clamped and fed to the next station. After processing, the workpiece can be sent to the tail end of the processing table 1 and pushed out by the pushing mechanism 3, thereby realizing automatic transportation of the workpiece.

[0023] Specifically, Figure 2-3 As shown, the clamping and feeding mechanism 2 includes a support frame 201, on which a pair of lifting cylinders 202 are fixed, and the output shaft of the lifting cylinder 202 is fixed with a lifting frame 203 which performs linear up and down motion on the support frame 201, and a clamping cylinder 204 is fixed on the front side of the lifting frame 203. The workpiece can be clamped by the clamping cylinder 204 and transferred horizontally. During the retraction process, the two jaws of the clamping cylinder 204 can be opened to a horizontal state without affecting the upstream workpiece.

[0024] A vertically arranged guide slider 205 is fixed on the support frame 201, and a guide rail 206 corresponding to the guide slider 205 is fixed on the support frame 201. The lifting cylinder 202 is pushed out or retracted. Under the guidance of the guide slider 205 and the guide rail 206, the lifting movement of the lifting frame 203 is more stable.

[0025] As for how the three groups of clamping and feeding mechanisms 2 are connected to each other and how they are driven together, two adjacent support frames 201 are connected by a long connecting plate 207, and a driving cylinder 208 is fixed on the processing table 1. The output shaft of the driving cylinder 208 is fixed to the rightmost support frame 201. The three groups of clamping and feeding mechanisms 2 can be controlled by the driving cylinder 208 to move together to realize feeding.

[0026] In order to ensure the stability of the clamping and feeding mechanism 2 during movement, a limiting slide rail 209 is fixed to the top surface of the processing table 1, and a limiting slider 210 slidably connected to the limiting slide rail 209 is fixed to the bottom surface of the support frame 201. The driving cylinder 208 is pushed out, and under the guidance of the limiting slider 210 and the limiting slide rail 209, the support frame 201 moves more stably.

[0027] The last set of clamping and feeding mechanisms 2 delivers the workpiece to the pushing mechanism 3, which can then deliver the workpiece after multiple processing steps. Figure 4As shown, the push mechanism 3 includes a support seat 301 fixed on the processing table 1, a pair of support rods 302 are fixed on the support seat 301, the clamping cylinder 204 sends the workpiece to the support seat 301, and is supported by the pair of support rods 302, and a linear module 303 is also fixed on the processing table 1, and a push seat 304 driven by the linear module 303 to perform linear motion forward and backward is fixed at the output end of the linear module 303, and the initial position of the push seat 304 is as shown in FIG. Figure 4 In the state shown, after the workpiece is transferred to the support rod 302, the linear module 303 can drive the pusher 304 to move forward to push the workpiece out.

[0028] By adopting the above-mentioned metal casting feeding device, the workpiece can be fed in an orderly manner to improve the continuity of the workpiece processing. The specific feeding method is as follows:

[0029] like Figure 1 In the shown state, each clamping cylinder 204 corresponds to a workstation. When the workpiece at the corresponding workstation is processed, the clamping cylinder 204 moves downward, and a pair of jaws of the clamping cylinder 204 move relative to each other and clamp the workpiece on the corresponding workstation. The clamping cylinder 204 is lifted and moved to the right. After the workpiece is placed on the next workstation, the pair of jaws of the clamping cylinder 204 are opened to a horizontal state and then can be retreated and returned to the corresponding workstation. The above operations are repeated to feed the workpiece regularly. When the workpiece is transferred to the support rod 302, the linear module 303 can drive the pusher seat 304 to move forward to push the workpiece out.

[0030] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0031] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
