Description

Technical Field

[0001] The invention relates to the technical field of valve production equipment, and in particular to a feeding device for valve upsetting based on mechanical claws. Background Art

[0002] The valve is one of the key parts in internal combustion engines such as gasoline engines and diesel engines, and works in a corrosive environment of high temperature, high pressure and gas generated by engine combustion.

[0003] The upsetting forming method is to heat one end of the bar with electricity and then perform upsetting or press die upsetting. Currently, upsetting is a way of forming valves, and upsetting is also the main way of processing valves in my country.

[0004] During the upsetting process, the bar with a larger outer diameter at one end needs to be placed on the upsetting equipment for processing, such as Figure 1 The bar shown includes a large diameter end and a small diameter end (the large diameter end referred to here is the part with a larger outer diameter of the bar, and the small diameter end is the part with a smaller outer diameter of the bar). Since the temperature of the upsetting equipment is relatively high, the bar generally needs to be placed on the equipment by a robot. Therefore, before the robot claw places the bar on the upsetting equipment, the larger diameter and smaller diameter ends of the bar need to be distinguished. Currently, some manufacturers manually distinguish the large end and the small end of the bar and place them in the grasping position of the robot claw, and then place them on the upsetting equipment through the robot claw. Manual loading is required, and one upsetting equipment requires at least one staff member to manually load the bar, which increases the labor cost in the processing cost. Summary of the invention

[0007] The feeding mechanism, the material dividing block, the material guiding assembly and the mechanical claw are sequentially mounted on the workbench;

[0008] A material distribution trough is provided on the upper surface of the material distribution block, and the feeding mechanism is used to transfer materials one by one to the material distribution trough in sequence. A material distribution channel is vertically provided at the bottom of the material distribution trough, and the width of the material distribution channel is larger than the outer diameter of the small diameter end of the material and smaller than the outer diameter of the large diameter end of the material;

[0012] As a further optimized solution of the present invention, the width of the material distribution trough gradually narrows from a side close to the feeding mechanism to a side away from the feeding mechanism.

[0013] As a further optimized solution of the present invention, the depth of the material distribution channel is greater than the length of the small diameter end of the material.

[0016] As a further optimized solution of the present invention, a clamping groove is transversely opened on a side of the material guide block away from the material distribution block, and the clamping groove is located in the loading station.

[0018] As a further optimized solution of the present invention, the first clamping rod and the second clamping rod are both L-shaped, and the first clamping rod and the second clamping rod relatively form a clamping frame with an opening on one side.

[0019] As a further optimized solution of the present invention, the material storage piece is provided with a material storage trough, and a material guide hole is provided on the side of the material storage piece, the material guide hole is connected with the material storage trough, the height of the material guide hole is greater than the outer diameter of the large diameter end of the material and less than twice the outer diameter of the small diameter end of the material, and the material guide hole connects the material storage trough and the material distribution trough.

[0020] As a further optimized solution of the present invention, the bottom surface of the material storage member is an inclined surface which gradually slopes downward from a side away from the material guide hole to a side close to the material guide hole.

[0032] Embodiment 1

[0033] like Figure 1-2 The feeding device for valve upsetting based on mechanical claws shown in the figure comprises a workbench 1, a feeding mechanism 3, a material dividing block 2, a material guiding mechanism 4 and a mechanical claw 5, wherein:

[0034] The feeding mechanism 3, the material dividing block 2, the material guiding assembly and the mechanical claw 5 are sequentially installed on the workbench 1. Specifically, the material dividing block 2 can be fixed to the upper surface of the workbench 1 by gluing or welding;

[0035] A material distribution trough 21 is provided on the upper surface of the material distribution block 2. The feeding mechanism 3 is used to sequentially transfer materials to the material distribution trough 21 one by one. A material distribution channel 20 is vertically provided at the bottom of the material distribution trough 21. The width of the material distribution channel 20 is greater than the outer diameter of the small diameter end of the material and smaller than the outer diameter of the large diameter end of the material. The material distribution channel 20 is provided along the length direction of the material distribution trough 21 and is located in the middle of the material distribution trough 21.

[0036] Specifically, the feeding mechanism 3 may be a feeding mechanism 3 with a hopper and a leakage hole in the prior art;

[0037] Preferably, the width of the material distribution trough 21 gradually narrows from the side close to the feeding mechanism 3 to the side away from the feeding mechanism 3, so that the small diameter end of the material falls into the material distribution channel 20;

[0038] Preferably, the depth of the material distribution channel 20 is greater than the length of the small diameter end of the material, thereby preventing the material or other debris from being stuck between the dividing surface between the large diameter end and the small diameter end of the material and the bottom surface of the material distribution trough 21;

[0039] Preferably, the bottom surface of the material distribution trough 21 is an inclined surface that gradually slopes downward from the side close to the feeding mechanism 3 to the side away from the feeding mechanism 3, so that the rod-shaped material can roll from the side of the material distribution trough 21 close to the feeding mechanism 3 to the side away from the feeding mechanism 3 under the action of its own weight;

[0040] After the material enters the material distribution trough 21, the material moves from one end of the material distribution trough 21 to the other end. During this process, the width of the material distribution trough 21 gradually narrows, thereby making the material gradually narrower.

[0041] The end of the material guiding mechanism 4 away from the material distributing trough 21 is a material loading station. The material guiding mechanism 4 is located on the side of the material distributing trough 21 away from the material loading mechanism 3, and is used to transfer the material in the material distributing trough 21 to the material loading station. Specifically, the material guiding mechanism 4 can be a mobile mechanism with a clamp in the prior art, the clamp is used to clamp the material, and the mobile mechanism is used to drive the clamp to move from the material distributing channel 20 to the material loading station. The mobile mechanism can be an electric cylinder, a cylinder or other structure that can drive the clamp to move horizontally in the prior art;

[0042] The mechanical claw 5 is used to move the material from the loading station to the upsetting equipment;

[0043] Specifically, the mechanical claw 5 includes a first clamping rod 50, a second clamping rod 51, a mounting plate 52, a driving clamping mechanism 53 and a horizontal moving mechanism 54, wherein: the horizontal moving mechanism 54 is an electric telescopic rod, the horizontal moving mechanism 54 is installed on the workbench 1, the mounting plate 52 is fixed to the moving end of the horizontal moving mechanism 54, the first clamping rod 50 and the second clamping rod 51 are both slidably installed on the mounting plate 52, the driving clamping mechanism 53 is used to drive the first clamping rod 50 and the second clamping rod 51 to move closer to or away from each other to clamp or release the material, and the driving clamping mechanism 53 is an electric cylinder that can drive the first clamping rod 50 and the second clamping rod 51 to move horizontally;

[0044] Preferably, the first clamping rod 50 and the second clamping rod 51 are both L-shaped, and the first clamping rod 50 and the second clamping rod 51 are relatively formed into a clamping frame with an opening on one side.

[0045] Those skilled in the art should know that in order to facilitate the sliding of the material in the material distribution trough 21 and reduce the friction coefficient, lubricating oil can be applied to the bottom surface of the material distribution trough 21;

[0046] During the working process, an upsetting equipment is equipped with a feeding device disclosed in the present invention. First, the material is placed in the feeding mechanism 3, and the feeding mechanism 3 sends the material to the dividing trough 21. Since the bottom of the dividing trough 21 is an inclined surface, the material in the dividing trough 21 rolls from one end of the dividing trough 21 to the other end. In this process, the width of the dividing trough 21 gradually narrows, so that the small diameter end of the material gradually approaches the middle and falls into the dividing channel 20, and then the small diameter end of the material falls into the dividing channel 20. The large diameter end of the material is in the dividing trough 21, and the material continues to slide to the side of the dividing trough 21 away from the feeding mechanism 3. The material guiding mechanism 4 moves the material to the feeding mechanism 3, and the horizontal moving mechanism 54 drives the first clamping rod 50 and the second clamping rod 51 to move to the feeding station, and drives the clamping mechanism 53 to drive the first clamping rod 50 and the second clamping rod 51 to move closer to each other and the first clamping rod 50 and the second clamping rod 51 clamp the small diameter end of the material. When the first clamping rod 50 and the first clamping rod 50 and the second clamping rod 51 clamp the small diameter end of the material, After the two clamping rods 51 clamp the material, the material is located in the clamping frame, and the open side of the clamping frame is close to the mounting plate 52; then the mechanical claw 5 and the material are driven to move to the upsetting equipment through the horizontal moving mechanism 54, and then the clamping mechanism 53 is driven to drive the first clamping rod 50 and the second clamping rod 51 to move away from each other, so that the material falls to the upsetting equipment under its own gravity. In order to make the first clamping rod 50 and the second clamping rod 51 play a buffering role, when the first clamping rod 50 and the second clamping rod 51 clamp the material, the contact position of the first clamping rod 50 and the second clamping rod 51 with the material is relatively low, and then the material freely falls downward during the movement of the first clamping rod 50 and the second clamping rod 51 away from each other, and the dividing surface between the large diameter end and the small diameter end of the material during the free fall movement contacts the first clamping rod 50 and the second clamping rod 51, thereby playing a buffering role, reducing the speed of the material when it contacts the upsetting equipment. The feeding device is aimed at equipment that upsets materials in the vertical direction.

The width of the material guide channel 400 is greater than the outer diameter of the material at the small diameter end and smaller than the outer diameter of the material at the large diameter end. The driving mechanism is installed on the material guide block 40 and is used to move the material in the material guide channel 400 from one end close to the material dividing block 2 to one end away from the material dividing block 2. The driving mechanism is a belt transmission mechanism 41. The belt transmission mechanism 41 is installed at the bottom of the material guide channel 400, and the material is located on the belt transmission mechanism 41.

[0050] Preferably, the material guide block 40 is further provided with a material guide groove 401, the material guide groove 401 is communicated with the material distribution groove 21, and the material guide channel 400 is provided at the bottom of the material guide channel 400, and the material guide groove 401 is coated with lubricating oil;

[0051] The width of the material guide trough 401 is slightly larger than the outer diameter of the large diameter end of the material;

[0052] A clamping groove 402 is transversely opened on one side of the guide block 40 away from the dividing block 2. The clamping groove 402 is located in the loading station and below the guide groove 401. The first clamping rod 50 and the second clamping rod 51 extend into the clamping groove 402 to clamp the material.

[0053] In addition, those skilled in the art should understand that the belt transmission mechanism 41 in this embodiment includes not only a conveyor belt, a driving pulley and a driven pulley, but also a reduction motor for driving the driving pulley to rotate;

[0054] During the working process: the material slides from the distribution channel 20 to the material guide channel 400 and the bottom of the material contacts the conveyor belt of the belt transmission mechanism 41, slides a certain distance under the action of inertia, and then the belt transmission mechanism drives the conveyor belt to move intermittently a certain distance to realize intermittent movement of the material to the loading station.

[0057] The bottom surface of the material storage member 30 is an inclined surface that gradually slopes downward from a side away from the material guide hole 301 to a side close to the material guide hole 301;

[0058] Preferably, a placement plate 31 is provided in the material storage trough 300 of the material storage member 30, and the placement plate 31 is connected to the material storage member 30 on one side close to the material guide channel 400. The width of the material storage trough 300 is slightly larger than the length of the material, and is hinged in the present embodiment.

The lifting mechanism 32 is an electric cylinder in the prior art, and a connecting plate 33 is fixed to the lifting end of the electric cylinder. The connecting plate 33 is arranged along the width direction of the material guide hole 301, and a support block 34 is fixed on the connecting plate 33, and the support block 34 is in contact with the placement plate 31. Two support blocks 34 are provided to increase the supporting effect on the placement plate 31; preferably, the support block 34 is in point contact with the placement plate 31, and the lifting mechanism 32 drives the support block 34 to move up and down, thereby tilting the placement plate 31, so that the material on the placement plate 31 rolls out of the material guide hole 301 sequentially or intermittently and moves to the distribution trough 21.

[0059] During the working process of this embodiment: the staff places the material on the placing plate 31 of the material storage piece 30.

After a certain period of time, the lifting mechanism 32 drives the support block 34 to move upward so that the upper surface of the placing plate 31 is an inclined surface tilted upward from the side close to the material guide hole 301 to the side away from the material guide hole 301, so that a material on the placing plate 31 is discharged from the material guide hole 301; thereby achieving intermittent feeding.
