Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a rapid positioning device suitable for irregular bending parts. Background Art

[0002] There are many types of excavators in the current excavator market. Some of the irregular parts in large excavators are difficult to locate when they are assembled. At this time, a quick positioning device for these irregular parts is needed. Irregular parts not only represent the irregular shape of the parts, but also the irregularity of the requirements for the position and angle after assembly. For example, a seemingly ordinary bent cover plate in the upper frame of the excavator has similar shaped parts used in many models of large excavators. Since there are other assembly parts on this type of bent cover plate, and most of them are parts with threaded holes, if a certain position or angle deviation occurs during installation, it will usually cause a large assembly error, such as the lead wire cannot be directly aligned with the interface or cannot contact the wheel excavation interface hole due to the length of the lead wire, thus affecting the assembly of the entire vehicle. Therefore, under normal circumstances, during the production process of the upper frame, the position and angle dimensions of the bent cover plate will be strictly controlled.

[0003] In the prior art, when assembling, workpiece two is placed on a tooling platform, and the assembler needs to place workpiece one, i.e., the bent cover plate, on the upper side of workpiece two and form a certain angle with workpiece two, and then support the bent cover plate through a triangular plate to ensure the key angle α01 and the key dimension △01. Since the bent cover plates usually used weigh tens of kilograms or even hundreds of kilograms, the assembler must use a crane to lift and align the angles, which is cumbersome, time-consuming and labor-intensive. In addition, this alignment method is also inaccurate and prone to dimensional errors. In addition, the triangular plate is also unstable when supporting the bent cover plate, which is prone to safety hazards.

[0004] Therefore, there is an urgent need for a rapid positioning device suitable for irregular bending parts to solve the above technical problems. Utility Model Content

[0005] The utility model aims to overcome the problems in the background technology and provide a rapid positioning device which is simple to operate, precise in positioning, highly safe and suitable for irregularly bent parts.

[0006] In order to achieve the above-mentioned utility model purpose, the utility model adopts a technical solution specifically as follows: a rapid positioning device suitable for irregular bending parts, comprising a bottom plate arranged at the bottom of one side of a tooling platform, two parallel side plates are arranged on the bottom plate, a rotating shaft is arranged between the two side plates, a positioning frame is sleeved on the rotating shaft, the positioning frame can rotate with the rotating shaft, so that the positioning frame can rotate and switch between the inner position one and the outer position two, when the positioning frame is in the position one state, the positioning frame and the tooling platform form an angle, a plurality of control panels are arranged on the upper side of the positioning frame away from one end of the rotating shaft, the control panel is used to support the bending part, a detachable positioning pin one is arranged on the control panel, the positioning pin one is used to limit the bending part to move along the width direction of the positioning frame, a mounting block is also arranged on the positioning frame, a detachable positioning pin two is arranged on the mounting block, the positioning pin two is used to limit the bending part to move along the length direction of the positioning frame, and a plurality of positioning clamps are also arranged on the positioning frame, the positioning clamps are used to press the bending part so that the bending part is close to the control panel.

[0007] Furthermore, a flip limit plate is provided on the bottom plate, and a baffle is provided on the lower side of the positioning frame. When the positioning frame flips to position two, the flip limit plate fits against the baffle, and the baffle stops after contacting the flip limit plate to ensure that the lowest point of the positioning frame is higher than the ground, thereby avoiding damage to the workwear, bumping against the ground and safety hazards.

[0008] Furthermore, the control board is provided with a plurality of pin holes along the width direction of the positioning frame, and the positioning pin is inserted into the pin hole. The positioning pin is detachably provided, and by inserting the positioning pin into different pin holes, bending parts of different sizes can be restricted in the width direction, and the application range is wider.

[0009] Furthermore, the mounting block is provided with a plurality of pin holes 2 along the length direction of the positioning frame, and the positioning pin 2 is inserted into the pin hole 2. The positioning pin 2 is detachably provided, and by inserting the positioning pin 2 into different pin holes 2, bending parts of different sizes can be restricted in the length direction, thereby enhancing the application scope of the positioning device.

[0010] Furthermore, the positioning clamp is movably arranged on the positioning frame, and the positioning clamp can rotate, so that the angle can be adjusted according to the shape of the specific bending part, and then clamped to make the bending part close to the control panel. Multiple positioning clamps can be provided and symmetrically arranged on both sides of the positioning frame. Multiple positioning clamps clamp simultaneously to make the installation of the bending part more firm and safe.

[0011] Furthermore, a notch is provided on one side of the tooling platform corresponding to the positioning frame, and the notch can enlarge the flipping angle of the positioning frame and form an acute angle between the tooling platform and the positioning frame.

[0012] Furthermore, a detachable limit block is provided on one side of the positioning frame close to the tooling platform. When the positioning frame is flipped to a position, the limit block fits against the upper surface of the tooling platform, and at this time, the limit block supports the positioning frame.

[0013] Furthermore, the limit block is longitudinally provided with a plurality of mounting holes, and the mounting holes may be jacks or threaded holes. By using different mounting holes, the mounting height of the limit block can be adjusted. Furthermore, the inclination angle of the positioning frame at one position can be adjusted. In this way, when the bending part is assembled with the workpiece two, the angle between the bending part and the workpiece two can be adjusted according to the specific assembly angle, thereby expanding the applicability of the rapid positioning device in terms of assembly angles.

[0014] Furthermore, one end of the rotating shaft passes through the side plate and is connected to a driving mechanism, and the driving mechanism can be implemented by an existing motor, a pneumatic device, etc.

[0018] 3. The positioning device is more stable and safer to use: the bending part is limited to a certain area by positioning pins 1 and 2, and the bending part can be clamped and fixed on the positioning frame by positioning clamps, which solves the problem of poor stability and potential safety hazards when traditional triangular plates are used to support the bending cover.

DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0030] Example: Figure 1-8As shown, this embodiment provides a rapid positioning device suitable for irregular bending parts, including a bottom plate 2 arranged at the bottom of one side of a tooling platform 1, two parallel side plates 3 are arranged on the bottom plate 2, a rotating shaft 4 is arranged between the two side plates 3, and a positioning frame 5 is sleeved on the rotating shaft 4. The positioning frame 5 can rotate with the rotating shaft 4, so that the positioning frame 5 can switch between the inner position 1 and the outer position 2. When the positioning frame 5 is in the position 1 state, the positioning frame 5 forms an angle with the tooling platform 1, and the positioning frame 5 is away from the rotating shaft. A plurality of control panels 6 are arranged on the upper side of one end of the positioning frame 4, and the control panel 6 is used to support the bending member 7. A detachable positioning pin 1 8 is arranged on the control panel 6, and the positioning pin 1 8 is used to limit the movement of the bending member 7 along the width direction of the positioning frame 5. The positioning frame 5 is also provided with a mounting block 9, and a detachable positioning pin 2 10 is arranged on the mounting block 9, and the positioning pin 2 10 is used to limit the movement of the bending member 7 along the length direction of the positioning frame 5. The positioning frame 5 is provided with four positioning clamps 11, and the positioning clamps 11 are used to press the bending member 7 to make the bending member 7 is close to the control panel 6, and a detachable limit block 17 is provided on one side of the positioning frame 5 close to the tooling platform 1. When the positioning frame 5 is flipped to the first position, the limit block 17 is in contact with the upper surface of the tooling platform 1. At this time, the limit block 17 supports the positioning frame 5. A plurality of mounting holes 18 are longitudinally arranged on the limit block 17. The mounting holes 18 can be jacks or threaded holes. By using different mounting holes 18, the installation height of the limit block 17 can be adjusted. Further, the inclination angle of the positioning frame 5 at the first position can be adjusted. In this way, when the bending part 7 is assembled with the workpiece 2, the angle between the bending part 7 and the workpiece 2 can be adjusted according to the specific assembly angle, thereby expanding the applicability of the rapid positioning device in terms of the assembly angle. One end of the rotating shaft 4 passes through the side plate 3 and is connected to the driving mechanism 19. The driving mechanism 19 can be realized by an existing motor, a pneumatic device, etc. A notch 16 is provided on one side of the tooling platform 1 corresponding to the positioning frame 5. The notch can expand the flipping angle of the positioning frame and form an acute angle between the tooling platform and the positioning frame.

[0031] A flip limit plate 12 is provided on the bottom plate 2, and a baffle 13 is provided on the lower side of the positioning frame 5. When the positioning frame 5 flips to the second position, the flip limit plate 12 fits with the baffle 13, and the baffle 13 stops after contacting the flip limit plate 12 to ensure that the lowest point of the positioning frame 5 is higher than the ground to avoid damage to the tooling, bumping against the ground and safety hazards.

[0032] The control board 6 is provided with a plurality of pin holes 14 along the width direction of the positioning frame 5, and the positioning pin 8 is inserted into the pin hole 14. The positioning pin 8 is detachably provided. By inserting the positioning pin 8 into different pin holes 14, the bending parts 7 of different sizes can be restricted in the width direction, and the application range is wider; the mounting block 9 is provided with a plurality of pin holes 15 along the length direction of the positioning frame 5, and the positioning pin 10 is inserted into the pin hole 15. The positioning pin 10 is detachably provided. By inserting the positioning pin 10 into different pin holes 15, the bending parts 7 of different sizes can be restricted in the length direction, thereby enhancing the application range of the positioning device.

[0033] The positioning clamp 11 is movably arranged on the positioning frame 5. The positioning clamp 11 can rotate so that the angle can be adjusted according to the specific shape of the bending part 7, and then clamped to make the bending part 7 close to the control board 6. Four positioning clamps 11 are set and symmetrically arranged on both sides of the positioning frame 5. The four positioning clamps 11 clamp at the same time to make the bending part 7 more firmly and safely installed.

[0034] Working principle:

[0035] When the tooling is idle, the quick positioning device is flipped to a position through a driving mechanism (such as a pneumatic device or a motor), so that the main body of the quick positioning device is located above the tooling platform, which occupies a small space and is convenient for storage;

[0036] When the quick positioning device is needed, first install the workpiece 2 on the tooling platform 1, and flip the quick positioning device from position 1 to position 2 through the driving mechanism 19, that is, stop when the baffle 13 contacts the flip limit plate 12, and then hoist the bending part 7 (that is, the workpiece 1) onto the quick positioning device through the crane, and the bending part 7 is placed on the control board 6. The positioning pins 1 8 on both sides are used to limit the width of the bending part 7, and the positioning pins 2 10 are used to limit the length direction of the bending part 7. The bending part 7 is clamped and fixed by four positioning clamps 11 so that the bending part 7 is tightly attached to the control board 6. After confirming that the bending part 7 is installed and fixed, the quick positioning device is flipped to position 1 through the driving mechanism 19. At this time, the bottom of the limit block 17 is in contact with the tooling platform surface 1, and the bending part 7 is placed on the workpiece 2, and forms a key angle α01 and a key size △01, and then the assembling personnel can perform the assembling operation.

[0037] It should be noted that when splicing workpieces of the same batch, pin 1, pin 2 and limit block do not need to be adjusted. When changing batches, due to the change in the size of workpiece 1, pin 1 and pin 2 need to be adjusted in width and length to adapt to the size of workpiece 1, and the height of the limit block is adjusted to adjust the angle between workpiece 1 and workpiece 2 to ensure the key angle and key size, thereby ensuring the accuracy of splicing.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
