Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile throttle, especially a dust cover pre-installation device for throttle. BACKGROUND

[0002] In the processing and manufacturing process of automobile throttle, the operation process of pre-installing the dust cover to the throttle body will be involved. In the existing operation, the dust cover is usually manually docked with the throttle body, and then a pressure device is directly started to press down on the dust cover, so as to press and install the dust cover and the throttle body and complete the pre-installation between the dust cover and the throttle body.

[0003] By manually docking the dust cover with the throttle body (including docking with the wire insertion piece and the insertion clamping piece, etc.), sometimes the docking is not accurate. If the pressing is carried out in the case of inaccurate docking, the docked part may be damaged, but the existing pre-installation device cannot know the above abnormal situation. UTILITY MODEL CONTENTS

[0004] The utility model aims at providing a dust cover pre-installation device for throttle, solving the technical problem that it is difficult to know the abnormal situation caused by inaccurate docking of the dust cover with the throttle body in the pressing process in the prior art. The utility model has the advantages of simple structure and convenient operation.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme:

[0006] A dust cover pre-installation device for throttle, comprising a mounting bottom plate, the upper end of the mounting bottom plate is provided with a side standing mounting plate, the side standing mounting plate is connected with a slide rail extending upward and downward, the slide rail is connected with a sliding block, the sliding block is connected with a dust cover limiting block, the dust cover limiting block is provided with a dust cover limiting groove penetrating upward and downward;

[0007] The upper part of the dust cover limiting groove is further provided with a pressing rod, and the lower end of the pressing rod is connected with a pressure sensor;

[0008] The lower part of the dust cover limiting block is further provided with a side baffle and a throttle body side pressing assembly; the throttle body side pressing assembly comprises a driving component one connected to the upper end of the mounting bottom plate and a throttle body pushing block moving back and forth toward the side baffle under the driving of the driving component one;

[0009] The side standing mounting plate is further connected with a driving component two driving the dust cover limiting block to move upward and downward and a driving component three driving the pressing rod to move upward and downward.

[0010] Further, the upper end of the mounting bottom plate is further provided with a positioning groove.

[0011] Further, the side wall of the dust cover limiting groove is further provided with a notch.

[0012] Further, the driving component one is a side pushing cylinder; the driving component two is a top pushing cylinder; and the driving component three is a servo motor.

[0013] Compared with the prior art, the dust cover pre-assembly device for the throttle valve has the following beneficial effects:

[0014] 1. In the utility model, the pressure sensor is arranged at the lower end of the pressing rod, and the pressure sensor acts as a pressing block after the pressing rod is pressed down. The pressure sensor not only exerts pressure but also detects the change of the pressure value at any time.

[0015] The change of the pressure value during the pressing process can be detected by the pressure sensor, and the detected change of the pressure value can be used to analyze and determine whether the pressing process is abnormal.

[0016] After the pre-assembly device is connected with the control system, the detected pressure value can be transmitted to the control system. The control system can compare the pressure value and its change with the pre-stored standard value (or called "set value") to determine whether the pressing process is abnormal.

[0017] When the dust cover is precisely connected with the throttle valve body, the change of the pressure value obtained by the pressure sensor will conform to the set value; otherwise, the change of the pressure value obtained by the pressure sensor will not conform to the set value.

[0018] 2. In the utility model, the dust cover limiting groove is through from top to bottom, and the dust cover can be placed in the dust cover limiting groove during operation. The dust cover can be limited to prevent lateral deviation.

[0019] 3. In the utility model, the side wall of the dust cover limiting groove is also provided with a notch, and the connecting part of the dust cover and the throttle valve body can be observed through the notch.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0031] As shown in Figures 1-4 , the utility model provides a dust cover pre-assembly device for throttle, including installation bottom plate. In this embodiment, the installation bottom plate includes bottom plate 1 and bottom plate connecting plate 15, as shown in Figure 1 . The bottom plate connecting plate 15 is fixedly connected to the upper end of the bottom plate 1, and other components are arranged on the installation bottom plate.

[0032] Specifically, as shown in Figure 1 , the upper end of the bottom plate 1 is provided with a side vertical mounting plate 2, the side vertical mounting plate 2 is connected with two sliding rails 7 extending upward and downward, the sliding rails 7 are connected with sliding blocks 8, the sliding blocks 8 are connected with dust cover limiting blocks 5, and the dust cover limiting blocks 5 are provided with dust cover limiting grooves 17 penetrating upward and downward, as shown in Figure 5 .

[0033] When operating, the dust cover 13 is placed in the dust cover limiting groove 17, as shown in Figure 3 , 4As shown, the dust cover 13 placed in the dust cover limiting groove 17 is limited by the dust cover limiting groove 17 and cannot be displaced in the lateral direction, thereby locking the position of the dust cover 13.

[0034] Meanwhile, the dust cover limiting groove 17 is through from top to bottom, i.e. open from top to bottom, the upper part of the dust cover limiting groove 17 is the pressure sensor 11, and the lower part of the dust cover limiting groove 17 is used to place the throttle body 14. The pressure sensor 11 is connected to the lower end of the pressure rod 10, and the pressure rod 10 is driven to move up and down by the servo motor 9. The servo motor 9 is connected to the side vertical mounting plate 2 through the connecting plate.

[0035] Meanwhile, as shown, Figure 1 The piston rod of the driving component two, i.e. the piston rod of the push air cylinder 6, is connected to the lower dust cover limiting block 5, and drives the dust cover limiting block 5 to move in the up and down direction.

[0036] As shown, Figure 1 Below the dust cover limiting block 5, the upper end of the bottom plate connecting plate 15 is also provided with a side baffle 12 and a throttle body side pressing assembly. The throttle body side pressing assembly includes a driving component one connected to the upper end of the mounting bottom plate and a throttle body pushing block 4 which moves back and forth in the direction of the side baffle 12 under the driving of the driving component one. In this embodiment, the driving component one is a side push air cylinder 3.

[0037] The throttle body pushing block 4 is connected to the front end of the piston rod of the side push air cylinder 3 and can push the throttle body 14 placed between the throttle body pushing block 4 and the side baffle 12 in the direction of the side baffle 12 under the pushing of the side push air cylinder 3, thereby locking the throttle body 14 between the throttle body pushing block 4 and the side baffle 12. Meanwhile, the side baffle 12 is fixed on the upper end of the bottom plate connecting plate 15 and its position is fixed. The end face of the side baffle 12 towards the throttle body pushing block 4 can act as a reference surface. When the throttle body 14 is in close contact with the side baffle 12, it means that the throttle body 14 has reached the preset position in the front and back direction.

[0038] Preferably, a positioning groove with an upper end opening (not shown in the drawings) can be additionally arranged at the upper end of the bottom plate connecting plate 15. After the throttle body 14 is placed between the throttle body pushing block 4 and the side baffle 12, the lower end of the throttle body 14 can be aligned with the positioning groove and placed into the positioning groove, so that the lower end of the throttle body 14 is matched and connected with the positioning groove, and the throttle body 14 can be quickly placed into the preset position. Then, the throttle body pushing block 4 is used to press the throttle body 14 against the side baffle 12 on the front side, so that the throttle body 14 is tightly attached to the side baffle 12. In addition, in the size design, when the lower end of the throttle body 14 is placed into the positioning groove, a certain gap can be left between the front and rear ends of the throttle body 14 and the groove wall of the positioning groove, that is, a certain displacement of the throttle body 14 towards the side baffle 12 is allowed, so as to realize the operation of the throttle body pushing block 4 to press the throttle body 14 against the front end face of the side baffle 12.

[0039] Meanwhile, in the present embodiment, the reinforcing rib 16 is further connected to the rear end of the side vertical mounting plate 2.

[0040] In the operation process, the throttle body 14 is first placed between the throttle body pushing block 4 and the side baffle 12 and below the dust cover limiting block 5. Then, the throttle body pushing block 4 pushes the throttle body 14 forward towards the side baffle 12, and at this time, the position of the throttle body 14 is locked. Then, the dust cover limiting block 5 is moved downward to the specified position, and a small part of the throttle body 14 enters the dust cover limiting groove 17 (as shown in Figure 3 Then, the dust cover 13 is placed in the dust cover limiting groove 17 and preliminarily aligned and spliced with the upper end of the throttle body 14, as shown in Figure 3 Finally, the pressure sensor 11 is driven to be pressed downward, serving as a pressing block to press the dust cover 13 downward against the throttle body 14, and at the same time, the pressure sensor 11 can acquire the pressure value and the change of the pressure value in the pressing process.

[0041] In the actual production process, the pressure sensor 11 and the servo motor 9 can be connected into the control system, and the change of the pressure value detected by the pressure sensor 11 can be sent to the control system. The control system can compare the pressure value detected by the pressure sensor 11 in the pressing process with the preset normal standard pressure value, so as to analyze and judge whether there is an abnormality in the pressing process. For example, if the throttle body 14 and the dust cover 13 are not completely aligned, and the wiring plug 20 is bent in the process of being pressed downward and inserted into the plug-in clamping piece 20, the sensor can detect a sudden change of the pressure value, that is, the pressure value is abnormal and does not conform to the change of the set value. When the pressure value is found to be abnormal, the control system can give a warning signal to prompt the operator to check in time.

[0042] Preferably, as shown in Figure 1 , 2 the side wall of the dust cover limiting block 5 in this embodiment is also provided with a notch 18, i.e. the side wall of the dust cover limiting groove 17 is provided with a notch 18, through which the abutment part of the dust cover 5 and the throttle body 14 can be observed.
