Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of forklift knuckle processing, in particular to a forklift knuckle notch cutting device. BACKGROUND

[0002] The forklift knuckle is an important part of the forklift, which is used to control the steering operation of the forklift. The knuckle is usually installed on the front axle of the forklift and connected to the steering wheel or control lever. The knuckle converts the input of the operator into the steering action of the forklift through a mechanical or hydraulic transmission system. When the operator turns the steering wheel or control lever, the knuckle will turn the front axle accordingly, thereby changing the direction of travel of the forklift. Some forklift knuckles have adjustable steering angles that can be adjusted as needed to adapt to different working environments and operating requirements.

[0003] The stability of the knuckle installation is very important to the structure of the forklift, and a notch is usually provided on the knuckle to enable the knuckle to be accurately and stably installed on the main body structure of the forklift.

[0046] Example 2

[0047] like Figure 2 and Figure 4 As shown, based on the above embodiments, this embodiment further provides the following:

[0048] In order to simultaneously clamp the end of the connecting pipe 72 with the spray clamp assembly 54 when the clamping assembly 51 presses down on the section body 71, the following structure is adopted;

[0049] The spray clamp assembly 54 comprises a first spring 543, a first guide rod 544, a second pressing plate 545 and a roller 547, the first guide rod 544 is connected through the top inner part of the toothed plate 513, the outer wall of the first guide rod 544 is sleeved with the first spring 543, one end of the first spring 543 is connected to the outer wall of the first guide rod 544 and the other end is connected to the side wall of the toothed plate 513, one end of the first guide rod 544 is fixed with the second pressing plate 545, the side wall of the second pressing plate 545 is connected with the roller 547, one side of the roller 547 is in close contact with the side wall of the guide rail frame 53 and rolls thereon.

[0050] In the process of the toothed plate 513 descending and the first pressing plate 515 pressing the knuckle 7, the first guide rod 544 is driven to descend and the roller 547 rolls on the guide rail frame 53, under the elastic pulling force of the first spring 543, the first guide rod 544 is pulled to extend, so as to clamp the second pressing plate 545 at the end of the connecting pipe 72, thereby improving the convenience of clamping and positioning the knuckle 7.

[0051] In the embodiment, the guide rail frame 53 comprises a first vertical section, an inclined section and a second vertical section, the first vertical section is fixed on the top of the inclined section and the second vertical section is fixed on the bottom of the inclined section, the roller 547 rolls along the first vertical section, the inclined section and the second vertical section in sequence so that the second pressing plate 545 extends outward to clamp the end of the connecting pipe 72.

[0052] Before the machining step of cutting the notch 711 of the knuckle 7, some debris generated in the previous steps may be left on the inner wall of the knuckle body 71, which may affect the positioning of the knuckle body 71 by the socket 41, in order to solve the above problem, the following structure is adopted.

[0053] In the embodiment, the spray clamp assembly 54 further comprises an air pump 541, a hose 542 and an air outlet pipe 546, the air pump 541 is connected with the hose 542 on the top, the air outlet pipe 546 is connected through the inside of the second pressing plate 545, one end of the hose 542 is connected with the inside of the air outlet pipe 546 in a penetrating manner, the support plate 11 is fixed on one side of the support table 1, the air pump 541 is arranged on the top surface of the support plate 11, the through hole 5151 is formed in the inside of the first pressing plate 515 and is connected with the inside of the plug column 516 in a penetrating manner.

[0054] When the second pressing plate 545 is clamped at the end of the connecting pipe 72 of the knuckle 7, the air outlet pipe 546 is inserted into the inside of the connecting pipe 72, then the air pump 541 is started to introduce air into the inside of the knuckle 7, so as to clean the residual debris in the inside of the knuckle body 71, thereby ensuring the flatness of the inner wall of the knuckle body 71 and the stability of the positioning of the knuckle body 71 on the socket 41; and when the notch 711 of the knuckle 7 is cut, the introduced air flows in the inside of the knuckle body 71 and is discharged from the inside of the plug column 516 and the second pressing plate 545, so as to realize the heat dissipation in the inside of the knuckle body 71 and ensure the stability of the cutting of the knuckle 7.

[0055] In this embodiment, the side wall of the socket 41 is provided with a through groove 411 that extends through the top.

The air that has entered the section 71 will be discharged from the bottom of the section 71, so that the discharged air can blow away the debris on the socket 41 and the base 4.

[0057] Example 3

[0058] like Figures 1-5 As shown, based on the above embodiments, this embodiment further provides the following:

[0059] The positioning mechanism 6 includes a second fixed plate 61, a limiting frame 62, a positioning seat 63, a screw 64, a rocker arm 65, and a fixed support assembly 66.

One side of the limiting frame 62 is fixed to the top surface of the support platform 1. The positioning seat 63 is slidably inserted inside the limiting frame 62. The screw 64 is threadedly connected inside the positioning seat 63. One end of the screw 64 is connected to the rocker arm 65. The fixed support assembly 66 is provided on the top surface of the positioning seat 63.

[0060] In this embodiment, one side of the positioning seat 63 has an arc-shaped structure, and the arc radius of the positioning seat 63 is equal to the circumferential arc radius of the base 4.

[0061] In this embodiment, the fixed support assembly 66 includes a second guide rod 661, a second spring 662, a support plate 663, a pad 664, a post 665, and a push rod 666. Two second guide rods 661 are connected through the inside of the support plate 663. Both second guide rods 661 are vertically fixed to the top surface of the positioning seat 63.

Then, by pressing the knuckle body 71 vertically, the second spring 662 is compressed by the support plate 663, so that the support plate 663 clamps the pull arm 73 in the opposite direction and upwards.

[0063] In the embodiment, the top surface of the base 4 is fixed with a limiting block 42, the limiting block 42 is mirror image arranged with two, the top of the adjacent side of the two limiting blocks 42 is a chamfer structure, the pull arm 73 is inserted between the two limiting blocks 42 through the lowering of the joint body 71;

[0065] The working principle and use process of the application are as follows:

[0066] First, press Figures 1-7 The pull arm 73 of the knuckle 7 is placed on the positioning mechanism 6, so that the insertion column 665 is inserted into the insertion hole 731 of the pull arm 73, the pull arm 73 is fitted on the bottom surface of the pad 664, the worker rotates the rocker 65, and at the same time pushes the push rod 666, the threaded rod 64 is screwed to drive the positioning seat 63 to slide in the limiting frame 62, until the circular surface of the positioning seat 63 is fitted on the outer wall of the base 4, the knuckle 7 is brought to the top of the base 4, and the pull arm 73 is rotated on the insertion column 665, so that the joint body 71 is rotated between the first pressing plate 515 and the socket 41;

[0067] Then, the motor 511 is started to drive the gear 512 to rotate, the gear 512 engages the transmission tooth plate 513 to descend, the tooth plate 513 drives the connecting plate 514 to descend, so that the plug column 516 is inserted into the joint body 71, until the first pressing plate 515 is fitted on the top surface of the joint body 71, then the first pressing plate 515 continues to press the joint body 71, the joint body 71 drives the pull arm 73 to descend, the pull arm 73 makes the supporting plate 663 descend and compresses the second spring 662;

[0068] In the process of descending the tooth plate 513, the second pressing plate 545 is driven to descend, at the same time, the roller 547 moves from the first vertical section of the guide rail frame 53 to the inclined section, the roller 547 rolls downward on the first vertical section of the guide rail frame 53, under the action of the pulling force of the first spring 543, the first guide rod 544 is pulled to drive the second pressing plate 545 to move towards the knuckle 7, until the roller 547 rolls on the second vertical section of the guide rail frame 53, the second pressing plate 545 is pressed on the port of the connecting pipe 72, the air outlet pipe 546 is inserted into the connecting pipe 72, then the air pump 541 is opened, air is introduced into the joint body 71 through the hose 542 and the connecting pipe 72, the air introduced blows away the debris attached to the inner wall of the joint body 71, the air in the joint body 71 is discharged from the through hole 5151 in the first pressing plate 515 and the bottom of the joint body 71 respectively, the air discharged from the bottom blows away the remaining debris and the debris on the base 4, so that the base 4 is cleaned;

[0069] Then continue to drive the gear plate 513 down again until the knuckle 7 is attached to the top surface of the base 4, the pull arm 73 is inserted between the two limiting blocks 42, and the positioning and clamping of the knuckle 7 is completed. Then start the electric sliding seat 2 to drive the cutting machine body 3 to move to cut the side wall of the knuckle body 71 to obtain the notch 711. In the cutting process, the air inside the knuckle body 71 carries away the heat generated by cutting to cool the knuckle body 71, thereby ensuring the stability and safety of the cutting process of the knuckle body 71.
