Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for machining cemented carbide top hammers, specifically a moving and transferring tooling for cemented carbide top hammers. Background Technology

[0002] Since the successful development of synthetic diamond by General Electric in 1954, the synthetic diamond industry has flourished. As a result, cemented carbide top hammers, which are indispensable for the synthesis of diamond, have also been developed and promoted. The top hammer is a key consumable in the synthesis of superhard materials. The quality of the top hammer determines the quality of diamond synthesis, and the processing efficiency of the top hammer also determines the price of the top hammer and the production cost of diamond.

[0003] In the packaging process of the top hammer, the top hammer needs to be wiped clean and placed upside down into the packaging box. The usual method is to use a conventional manual suction cup to hold the bottom of the top hammer for transfer. However, the load-bearing capacity of this manual suction cup is limited. For top hammers with a diameter of D160 or larger, they often fall off the suction cup during the transfer process, which poses a serious threat to the personal safety of employees. At the same time, the manual suction cup is not convenient for quick operation, which affects the production efficiency of the top hammer. Utility Model Content

[0004] The purpose of this invention is to propose a cemented carbide top hammer moving and transferring fixture, which transfers the top hammer through vacuum adsorption, thereby improving the load-bearing capacity of the top hammer. At the same time, it adds safety measures on the basis of vacuum adsorption to ensure employee safety, improve processing efficiency, and reduce the labor intensity of employees.

[0005] The technical solution adopted in this utility model is: a cemented carbide top hammer moving and transferring tooling, including a frame and a valve, a suction cup and a limiting rod set on the frame; one end of the valve is connected to an external negative pressure device, and the other end is connected to the suction cup;

[0006] The valve has a valve stem capable of linear displacement to switch between a closed state and an open state; a valve reset push rod and a valve control trigger are fixed to the outer end of the valve stem, which can drive the valve stem to perform linear displacement, and the valve reset push rod is provided with a limit groove;

[0007] The limiting rod has a safety reset push rod that can move toward or away from the valve stem; when the safety reset push rod moves toward the valve stem, it can engage with the limiting groove to keep the valve in the open state; when the safety reset push rod moves away from the valve stem, it can release the restriction on the valve reset push rod.

[0008] As a preferred embodiment, the frame is rectangular in shape, with a connector fixed at the top, the valve located in the cavity in the middle of the frame, and the suction cup located at the bottom of the frame.

[0009] As a preferred embodiment, the frame has at least one vertical grip portion that cooperates with the valve control trigger.

[0010] As a preferred embodiment, the frame and the valve are connected by a valve seat;

[0011] The valve seat is provided with a guide groove, and the valve control trigger has a guide protrusion that slides in conjunction with the guide groove.

[0012] As a preferred embodiment, the outer end of the valve stem is a threaded section, and the end face of the valve reset push rod is provided with a threaded hole that mates with the threaded section.

[0013] As a preferred embodiment, the valve control trigger has a light hole in the middle for the threaded section to pass through, and the end of the threaded section away from the valve reset push rod has a shoulder.

[0028] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0029] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," etc., used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one; the terms "first," "second," and "third," as used herein, should not be considered as a limitation on the order of components, but are merely for distinguishing different components; the terms "comprising" or "including," etc., indicate that the elements or objects preceding "comprising" or "including" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0030] To more clearly describe the specific structural composition of this carbide top hammer moving and transferring fixture, in conjunction with the attached... Figure 1-3 This embodiment is described as follows:

[0031] like Figure 1-3 As shown, a cemented carbide top hammer moving and transferring fixture includes a frame 1 and a valve 3, a suction cup 4 and a limiting rod disposed on the frame 1; one end of the valve 3 is connected to an external negative pressure device (vacuum generator) and the other end is connected to the suction cup 4;

[0032] The valve 3 has a valve stem 301 that can move linearly to switch between the closed state and the open state; the outer end of the valve stem 301 is fixed with a valve reset push rod 8 and a valve control trigger 9 that can drive the valve stem 301 to move linearly, and the valve reset push rod 8 is provided with a limit groove 801.

[0033] The limiting rod has a safety reset push rod 5 that can move toward or away from the valve stem 301. When the safety reset push rod 5 moves toward the valve stem 301, it can engage with the limiting groove 801 to keep the valve 3 in the open state, preventing accidental switching of the valve 3 to the closed state and ensuring stable adsorption of the hard alloy hammer 10 by the suction cup 4. When the safety reset push rod 5 moves away from the valve stem 301, it can release the restriction on the valve reset push rod 8. After the hard alloy hammer 10 is transferred to the position, the restriction on the valve reset push rod 8 is released to separate the suction cup 4 from the hard alloy hammer 10.

[0034] The frame 1 is rectangular in shape. A connector 101 is fixed at the top of the frame 1. An external electric hoist is connected through the connector 101. The electric hoist drives the frame and the entire transfer fixture to move. The valve 3 is located in the cavity in the middle of the frame 1, which can prevent the valve from being accidentally touched to a certain extent. The suction cup 4 is located at the bottom of the frame 1. The suction cup 4 is used to adsorb the inverted hard alloy top hammer 10.

[0035] See Figure 2 The frame 1 has at least one vertical grip 102, which works in conjunction with the valve control trigger 9. During transport, the user holds the vertical grip 102 of the frame 1 and pulls the valve control trigger 9 with their index finger. In this process, the valve 3 can be opened by pulling the valve control trigger 9 with one hand. At the same time, the limiting rod can quickly lock the valve 3 in the open state, without any extra operation, making the operation convenient and quick.

[0036] The frame 1 and the valve 3 are connected by a valve seat 2; the valve seat 2 is provided with a guide groove 201, and the valve control trigger 9 has a guide protrusion 901 that slides in cooperation with the guide groove 201. This sliding cooperation can limit the circumferential rotation of the valve reset push rod 8 and the valve control trigger 9, ensuring the stability when operating the valve control trigger 9.

[0037] The valve stem 301, valve reset push rod 8, and valve control trigger 9 are connected in a detachable manner to facilitate the replacement of individual parts. The specific connection method is as follows:

[0038] The outer end of the valve stem 301 is a threaded section 302. The end face of the valve reset push rod 8 is provided with a threaded hole that mates with the threaded section 302. The valve control trigger 9 is provided with a smooth hole in the middle for the threaded section 302 to pass through. The end of the threaded section 302 away from the valve reset push rod 8 is provided with a shoulder. The valve control trigger 9 is clamped between the end face of the valve reset push rod 8 and the shoulder of the threaded section 302.

[0039] The end of the valve reset push rod 8 away from the valve 3 is the pressing end. To facilitate the operation of the pressing end, the pressing end can be extended to the outside of the frame 1.

[0040] The limiting rod includes a safety cover 6 fixed on the frame 1, and a safety reset push rod 5 slidably disposed in the shaft hole of the safety cover 6; one end of the safety reset push rod 5 is a snap-fit ​​end that can cooperate with the limiting groove 801, and the other end is a handheld end that extends to the outside of the safety cover 6, and the handheld end is used by the operator to hold it.

[0041] To ensure that the locking end of the safety reset push rod 5 can quickly fall into the limiting groove 801 when the valve is open, a safety spring 7 is sleeved on the safety reset push rod 5. The safety spring 7 can provide the safety reset push rod 5 with a thrust to move towards the valve stem 301. The safety spring 7 is a compression spring. Specifically, an annular protrusion can be provided on the outer circumferential surface of the safety reset push rod 5. After the compression spring is sleeved on the outside of the safety reset push rod 5, one end abuts against the end face of the safety cover 6, and the other end abuts against the annular protrusion.

[0042] The safety cover 6 is provided with a through groove, and the valve reset push rod 8 slides in the groove. This method can improve the stability of the valve reset push rod 8 during linear displacement.

[0043] During the specific transfer process:

[0044] The transfer fixture needs to be used in conjunction with a mobile gantry crane, an electric hoist, and a vacuum generator. During use, an air hose is needed to connect the valve 3 of the transfer fixture to the vacuum generator, and the connecting piece 101 on the upper part of the frame 1 of the transfer fixture is hung on the hook of the electric hoist. When hoisting the carbide top hammer 10, the top hammer should be placed upside down with the bottom facing up. First, operate the electric hoist to place the suction cup 4 of the transfer fixture on the bottom surface of the top hammer. After confirming that the suction cup 4 is in close contact with the bottom surface of the top hammer, hold the vertical grip part 102 of the frame 1 with one hand and use the index finger to pull the valve control trigger 9. The valve 3 connects the air passage of the vacuum generator and the suction cup 4. After the suction cup 4 firmly sucks the bottom surface of the top hammer with atmospheric pressure, operate the electric hoist to lift and transfer the transfer fixture and the top hammer as a whole. After the top hammer is moved to the target position, operate the electric hoist to lower the transfer fixture and the top hammer as a whole. After the top hammer is placed firmly, pull up the safety reset push rod 5 with one hand and press the valve reset push rod 8 with the thumb of the other hand. After the valve resets, it cuts off the air passage between the vacuum generator and the suction cup 4, and the suction cup 4 separates from the top hammer, thus completing the top hammer transfer process.

[0045] The parts not described in detail in the above embodiments are existing technologies.

[0046] It should be noted that although the present invention has been described through the above embodiments, there may be other various embodiments of the present invention. Without departing from the spirit and scope of the present invention, those skilled in the art can obviously make various corresponding changes and modifications to the present invention, but all such changes and modifications should fall within the scope of protection of the appended claims and their equivalents.
