[0040] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Apparently, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0041] The following combines Figures 1 to 7 , and describes the embodiments of the present utility model.

[0042] According to an embodiment of the present utility model, a press-fitting tooling is provided for press-fitting a to-be-press-fitted part onto a workpiece. The press-fitting tooling includes: a press-fitting bracket 1, a clamping mechanism 3, and a press-fitting mechanism 2. The clamping mechanism 3 is disposed on the press-fitting bracket 1. The clamping mechanism 3 has a clamping state of clamping onto the workpiece and a separating state of separating from the workpiece. The press-fitting mechanism 2 includes a driving member 201 and a press-fitting member 202. The driving member 201 is disposed on the press-fitting bracket 1. The press-fitting member 202 is connected to the driving end of the driving member 201. The press-fitting member 202 has a press-fitting state of press-fitting the to-be-press-fitted part under the drive of the driving member 201 and a reset state of resetting under the drive of the driving member 201. Wherein, when the clamping mechanism 3 is in the clamping state, the driving member 201 drives the press-fitting member 202 to be in the press-fitting state. When the press-fitting member 202 is in the reset state, the clamping mechanism 3 can switch from the clamping state to the separating state.

[0043] When applying the press-fitting tooling of this embodiment to press-fit a to-be-press-fitted part, place the press-fitting tooling at the to-be-press-fitted position of the workpiece and clamp it onto the workpiece through the clamping mechanism 3. Then, control the driving member 201 to drive the press-fitting member 202 to press-fit the to-be-press-fitted part onto the workpiece. After the press-fitting is completed, control the driving member 201 to drive the press-fitting member 202 to reset to the initial state, and the clamping mechanism 3 separates from the workpiece, completing the press-fitting of one to-be-press-fitted part. Repeat the above steps to complete the press-fitting of all to-be-press-fitted parts. The press-fitting tooling uses the workpiece as a bearing point and performs press-fitting through the driving member 201, which can quickly realize the press-fitting of the to-be-press-fitted part, has high installation efficiency, does not require manual knocking of the to-be-installed part, reduces the labor intensity of the installer, and the installer can operate with the press-fitting tooling in hand, which is light, flexible, and can be operated by a single person.

[0044] It should be noted that the to-be-press-fitted part is a guide wheel assembly 803, and the workpiece is a column 8. The column 8 includes a column body 801, a wheel shaft 802, and a guide wheel assembly 803. This press-fitting tooling can be applicable to the wheel shaft press-fitting scenario of long beam components.

[0045] Further, as Figure 1 shown, the press-fitting member 202 is a pressing plate. The guide wheel assembly 803 is press-fitted through the pressing plate. The structure of the pressing plate is simple and easy to implement. The pressing plate has a chamfer for centering the guide wheel.

[0046] In one embodiment, as Figure 1 shown, the clamping mechanism 3 includes two oppositely arranged swing arms 301. The first end of each swing arm 301 is swingably connected to the press-fitting bracket 1. The second end of each swing arm 301 forms a clamping portion 3011 for clamping onto the workpiece. By clamping the two swing arms 301 on the opposite sides of the workpiece, the clamping is more stable, the downward movement of the press-fitting member 202 is more stable, and the press-fitting accuracy is improved.

[0047] In one embodiment, the swing arm 301 is in contact with the press-fitting part 202, and the clamping part 3011 of the swing arm 301 is retracted inwardly as the press-fitting part 202 is pressed downward, so that the clamping mechanism 3 switches from the separation state to the clamping state. The swing arm 301 is driven to swing by the downward pressing action of the press-fitting part 202, and there is no need to set a driving mechanism for driving the swing arm 301 to swing, thereby reducing the number of driving mechanisms and saving costs.

[0048] It is understandable that, in another embodiment, a power mechanism for driving the swing arm 301 to swing is provided on the press-fitting bracket 1, and the swing arm 301 is driven to swing by the power mechanism.

[0049] In one embodiment, the press-fitting tool further includes a moving part, which is arranged on the swing arm 301 and between the clamping portion 3011 and the press-fitting part 202. The moving part has a supporting state in which it is supported on the surface of the workpiece and slides on the surface of the workpiece, and the moving part also has a leaving state in which it leaves the surface of the workpiece as the press-fitting part 202 is pressed downward. When the press-fitting tool needs to be moved, the installer directly drags the press-fitting bracket 1, and the moving part can slide on the surface of the workpiece. The setting of the moving part enables the press-fitting tool to be flexibly and quickly moved on the column 8. The sliding of the moving part replaces manual handling, which saves effort during movement and reduces labor intensity.

[0050] Furthermore, when the pressing tool is placed on the workpiece, it is supported on the surface of the column 8 by the moving part, and then the driving part 201 is controlled to drive the pressing part 202 to press down. When the pressing part 202 contacts the guide wheel assembly 803, the pressing part 202 continues to press down, and the downward movement of the pressing part 202 drives the swing arm 301 to swing inward until the clamping part 3011 is close to the wing plate of the column 8, and the moving part is separated from the surface of the column 8, and the support of the moving part on the column 8 is transformed into the swing arm 301, the pressing bracket 1, the pressing mechanism 2 and the guide wheel assembly 803 cooperate to support on the column 8. The support of the pressing tool is changed by the ingenious cooperation of the moving part, the swing arm 301 and the pressing part 202, which simplifies the tooling structure and reduces costs.

[0051] In one embodiment, Figure 1 , Figure 2 and Figure 5 As shown, the movable part is a freely rotatable roller 401. By rolling the roller 401 on the surface of the column 8, the roller 401 and the column 8 are in rolling cooperation, which can significantly reduce the friction coefficient between the movable part and the column 8, thereby reducing the wear between the roller 401 and the column 8 and extending the service life of the movable part.

[0052] It can be understood that, in another embodiment, the moving member is a slider.

[0053] In one embodiment, Figures 1 to 3As shown, the press-fitting tooling further includes a roller bracket 402. The roller bracket 402 is fixed to the swing arm 301, and the roller 401 is rotatably arranged on the roller bracket 402. The arrangement of the roller bracket 402 makes it more convenient to install the roller 401 and reduces the assembly difficulty.

[0054] Further, at least two rollers 401 are provided on each swing arm 301, making the movement of the tooling on the column 8 more stable and reliable. The roller bracket 402 is generally U-shaped. Roller brackets 402 are provided on opposite sides of each swing arm 301, and at least one roller 401 is provided on each roller bracket 402. Of course, the shape of the roller bracket 402 is not limited to this, as long as the structure capable of installing the roller 401 can be used.

[0055] It can be understood that in another embodiment, the roller bracket 402 may not be provided, and the roller 401 may be directly installed on the swing arm 301.

[0056] In one embodiment, as Figure 2 shown, first guide members 501 are provided on opposite sides of the press-fitting member 202, and second guide members 502 are provided on the inner sides of the first ends of the swing arms 301. The second guide members 502 are in abutting and cooperating connection with the second guide members 502. Through the cooperation of the two guide members, the movement of the press-fitting member 202 can drive the swing of the swing arm 301, which is easier to achieve and simplifies the structures of the press-fitting member 202 and the swing arm 301.

[0057] Further, the first guide member 501 is a first guide plate, and the second guide member 502 is a second guide plate. The guide plates are formed by plates, with simple structures and being convenient for processing and manufacturing.

[0058] It can be understood that the two guide members may not be provided, and the mutually cooperating structures may be directly machined on the press-fitting member 202 and the swing arm 301.

[0059] In one embodiment, the press-fitting tooling further includes a limiting member 6. The limiting member 6 is arranged on the swing arm 301 and can cooperate with the press-fitting bracket 1 to limit the swing angle of the swing arm 301 swinging outwards. The movement range of the swing arm 301 is automatically limited through mechanical limiting to ensure that the swing arm 301 swings within a preset range. Specifically, the limiting member 6 is a limiting block arranged on the swing arm 301.

[0060] Further, the limiting block includes a fixing portion and a limiting portion. The fixing portion is arc-shaped, and the limiting portion is located above the mounting plate and can be in abutting and cooperating connection with the upper surface of the mounting plate.

[0061] In one embodiment, as Figure 1As shown in the figure, the press-fitting bracket 1 includes a mounting plate 101 and a handle 102 provided on the mounting plate 101. The driving member 201 is fixed on the mounting plate 101, and the clamping mechanism 3 is provided on the mounting plate 101. The mounting plate 101 facilitates the installation of the driving member 201 and the swing arm 301, and the handle 102 facilitates the installer to pick up and move the tooling.

[0062] Further, the handle 102 is an inverted U-shaped plate, and the driving member 201 is located inside the inverted U-shaped frame, making full use of the space inside the inverted U-shaped frame to make the tooling layout more compact and flexible.

[0063] In one embodiment, the press-fitting bracket 1 further includes a fixing member 103 fixed on the handle 102. The driving member 201 is a hydraulic push rod, and the press-fitting bracket 1 further includes a hydraulic component 203 fixed on the fixing member 103. The hydraulic component 203 is conveniently fixed through the fixing member 103, and the fixing is simple.

[0064] Further, the hydraulic component 203 includes a hydraulic pump, an oil tank, a reversing valve, etc. The inlet of the hydraulic pump is communicated with the oil tank, and the outlet of the hydraulic pump is communicated with the hydraulic push rod through the reversing valve. The extension or retraction of the hydraulic push rod is controlled through the reversing valve.

[0065] Specifically, the fixing member 103 is a U-shaped plate, and the open end of the U-shaped plate is fixed on the vertical plate of the inverted U-shaped plate.

[0066] Further, as Figure 1 and Figure 2 shown, two pairs of ear plates 104 are provided on the mounting plate 101. The swing arm 301 is connected to the ear plates 104 through pins 105. The handle 102 and the ear plates 104 are fixed on the mounting plate 101 by welding. The hydraulic push rod is fixed on the mounting plate 101 by bolts. The second guide plate, the roller bracket 402, and the limit block are fixed on the swing arm 301 by welding. The first guide plate is fixed on the pressing plate by welding. The pressing plate is connected to the hydraulic push rod by threads. The roller 401 is connected to the roller bracket 402 by threads.

[0067] It can be understood that in other embodiments, the hydraulic component 203 can also be fixed on the mounting plate 101.

[0068] The press-fitting process of the press-fitting tooling will be described below:

[0069] Place the press-fitting tooling on the column 8 of the curing kiln so that the roller 401 contacts the upper surface of the column 8 of the curing kiln. The roller 401 can be used to move the tooling on the upper surface of the column 8. Due to the action of the two guide plates, the initial state of the swing arm 301 deviates outward by 5°. The limit block can limit the position of the swing arm 301;

[0070] Start the hydraulic push rod. The hydraulic push rod pushes the pressure plate downward. The thrust causes the first guide plate to slide along the second guide plate. When the pressure plate contacts the guide wheel assembly 803, continue to press down the pressure plate. The roller 401 disengages from the surface of the column 8. At the same time, the swing arm 301 contracts inward until the clamping portion 3011 of the swing arm 301 presses against the lower surface of the wing plate of the column 8. The hydraulic push rod continues to push the pressure plate downward. At this time, the guide wheel assembly 803 is pressed onto the axle 802 of the column 8.

[0071] After the press-fitting is completed, the hydraulic push rod drives the pressure plate to move upward and retracts to the initial state.

[0072] In the related art, a guide wheel assembly needs to be installed on the column. Since the bearing of the guide wheel assembly is tightly fitted with the axle, a copper bar needs to be used to knock during the installation process. The labor intensity is high and the efficiency is low. Knocking is likely to cause damage to the bearing and generate quality risks. The column is relatively long and difficult to hoist, and the press-fitting scheme of "fixing the press and moving the workpiece" cannot be adopted. There are about 7 - 12 groups of guide assemblies on a PC line, and about 500 guide wheel assemblies need to be installed. The installation quantity is large, and it is urgent to improve the installation efficiency and reduce the labor intensity.

[0073] In this embodiment, the press-fitting tooling adopts a sliding structure and a lightweight design. The overall structure is simple and lightweight, with high cost performance. It is not affected by single / double-sided wheels, guide wheel spacing, long / short axles, and is suitable for the press-fitting scenario of the axle of long beam components. Using the workpiece for clamping as the load-bearing point reduces the press-fitting height. It adopts an integrated hydraulic push rod, and realizes the opening and closing movement by means of the telescoping of the hydraulic push rod and the limit of the guide plate. After being powered on, it can be operated by hand. It is light and flexible, can be operated by a single person, and can also greatly reduce the size and weight of the mechanism. It realizes the quick replacement of the swing arm and is compatible with the press-fitting of long and short axle guide wheels. The control of the press-fitting action is realized through the second guide plate and the limit block of the swing arm 301, and the control is simple. The roller 401 is arranged on the swing arm 301, which can realize the movement on the H-shaped steel, so that the tooling can move quickly and flexibly on the column 8, and the sliding through the roller 401 replaces manual handling, making the movement more labor-saving and reducing the labor intensity.

[0074] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations fall within the scope defined by the appended claims.
