[0035] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] It should be understood that for this application:

[0037] Automobile manufacturers need flexible and changeable automobile mixed-line production technology more than ever before. At present, vehicle manufacturers mainly achieve mixed flow through flexible fixture switching mechanisms; it can be understood that different models correspond to different production lines, and the change of a certain parameter requires the replacement of the production equipment at the corresponding workstation on the same production line. During the replacement process, a flexible fixture switching mechanism is required to switch different equipment, including fixture equipment or grippers for fixture materials. Flexible fixture switching mechanisms usually have import and export ports, but currently new equipment is sent into the import and export ports by hoists and forklifts.

[0038] However, there are certain requirements for the accuracy of the installation position of the new equipment. Generally, the delivery process is time-consuming and labor-intensive. Therefore, the embodiment of the present application provides a fixture switching import and export alignment platform to solve the problem in the related technology that the fixture can only be unloaded from the import and export port by a hoist or a forklift, resulting in a long time for fixture replacement and inaccurate positioning.

[0039] See also Figure 1 and Figure 2 , a fixture switching import and export centering platform, comprising:

[0040] The platform assembly 1 has a support assembly 2 on its top, and the support assembly 2 includes a spherical guide member 200 for supporting the fixture bottom plate 3;

[0041] Two telescopic components 4 are installed on the platform component 1 at intervals and are both connected with a clamp abutment 5; a clamp centering channel 6 is formed between the two clamp abutment 5, and the support component 2 is located in the clamp centering channel 6;

[0042] The control assembly 7 is connected to the telescopic assembly 4 and moves the clamp abutment 5 through the telescopic assembly 4 to change the size of the clamp centering channel 6 and is used to move the clamp base plate 3.

[0043] With the above settings, there are the following steps when using it:

[0044] The first step is to place the platform assembly 1 at the import and export port position of the fixture switching mechanism 9 so that the central axis of the platform assembly 1 is coaxial with the central axis of the import and export port; then connect and fix the bottom of the platform assembly 1 to the ground or the bottom of the fixture switching mechanism 9 by screws or other fixings.

[0045] In the second step, the fixture of the device to be replaced is placed on the support assembly 2 (that is, the fixture base plate 3 of the fixture is in contact with the support assembly 2) and moved; then the control assembly 7 adjusts the fixture abutment 5 and the fixture base plate 3 to abut against each other through the telescopic assembly 4 to determine the size of the fixture centering channel 6, and at the same time, the fixture base plate 3 moves in the fixture centering channel 6; this state refers to Figure 4 As shown, the center axis a of the fixture base plate 3 does not coincide with the center axis b of the platform assembly 1 .

[0046] In the third step, during the movement, the control component 7 adjusts the clamp support 5 again through the telescopic component 4, thereby moving the clamp base plate 3 and the clamp centering channel 6, so that the clamp base plate 3 is coaxially aligned and enters the introduction and export port of the clamp switching mechanism 9. The above whole process is adjusted and aligned during movement, which is easy to operate and does not require repeated adjustment using a sling or forklift, and the clamp replacement efficiency is high. The final state after adjustment is as follows Figure 5 and Figure 6 As shown, the center axis a of the fixture base plate 3 coincides with the center axis b of the platform assembly 1 .

[0047] In addition, the setting of the ball guide 200 enables the clamp bottom plate 3 to move in any direction, and can be adjusted left and right during the movement to the inlet and outlet of the clamp switching mechanism 9. It can be understood here that if the ball guide 200 is a guide roller, it is actually carried out during the movement process. There is a large friction force when the clamp bottom plate 3 is moved and adjusted in the left and right directions, so the ball guide 200 is used. The connecting line between the left and right directions is set perpendicular to the central axis of the clamp centering channel 6.

[0048] It should be understood from the above that since the replaced devices all have the clamp base plate 3, only the clamp base plate 3 is used as the adjustment object for description.

[0049] In some preferred embodiments, the above facilitates the adjustment of the centering of the fixture bottom plate 3 and the import and export ports so that they reach the accurate position. In order to further speed up the adjustment process and know whether the adjustment is accurate, the following settings are provided:

[0050] A laser distance sensor is provided on the clamp abutment 5, and the laser distance sensor is used to detect the distance between the clamp abutment 5 and the clamp bottom plate 3;

[0051] The control component 7 is connected to a telescopic length detection unit, which is connected to the telescopic component 4 and is used to detect the telescopic length of the telescopic component 4; the control component 7 is used to control all the telescopic components 4 according to the telescopic length detected by the telescopic length detection unit when it detects that the clamp abutment 5 is in contact with the clamp base plate 3, so that the clamp base plate 3 is aligned with the import and export port of the clamp switching mechanism 9 during the movement of the top of the platform component 1.

[0052] The above is achieved by using the laser distance sensor to know whether the clamp abutment 5 is in contact with the clamp bottom plate 3 and determine the size of the clamp centering channel 6; after the contact, the telescopic length detection unit is used to detect the telescopic length of the telescopic component 4; the control component 7 makes judgments and analyses based on the telescopic lengths of the two telescopic components 4;

[0053] Since the installation position of the platform component 1 is relatively aligned with the quasi-clamp switching mechanism 9, when the clamp base plate 3 is aligned with the import and export ports, the telescopic lengths of the telescopic components 4 on both sides should be equal and equal to the set telescopic length; therefore, when the telescopic length of the telescopic component 4 reaches the set telescopic length and the telescopic lengths of the two telescopic components 4 are equal, the locking is stopped and the adjustment is completed. Subsequently, only the clamp base plate 3 needs to be moved. The above settings achieve real-time and precise adjustment and alignment.

[0054] In some preferred embodiments, in order to realize support and facilitate adjustment of the mobile fixture base plate 3 during the entire movement process, the support assembly 2 is further configured as follows:

[0055] The support assembly 2 includes a plurality of columns and is arranged at intervals; each column of the support assembly 2 includes a plurality of spherical guide members 200 distributed in a straight line.

[0056] The spherical guide member 200 includes a mounting base plate 201 , a sleeve 202 is disposed on the top of the mounting base plate 201 , a spherical groove is disposed on the top of the sleeve 202 , and a supporting ball 203 is rotatably disposed in the spherical groove.

[0057] The above multi-row support assembly 2 can always provide support during the movement, and can move in any direction through the setting of the support ball 203, which is convenient for adjusting the clamp support member 5. In addition, the spacing distance between the spherical guide members 200 and the spherical guide members 200 can be the same or different, and the distance between them can be adjusted by installing the base plate 201.

[0058] For further reference, Figure 1 and Figure 2 , the clamp abutment 5 comprises a connecting plate 500 parallel to the straight line, and a plurality of L-shaped supports 501 distributed in a straight line are provided on the connecting plate 500;

[0059] One side of the vertical plate of the L-shaped support 501 in the thickness direction is connected to the connecting plate 500, and the other side of the vertical plate in the thickness direction is a platform supporting portion; the end of the horizontal plate of the L-shaped support 501 away from the vertical plate has a supporting surface for fitting with the side edge of the clamp bottom plate 3.

[0060] The above setting of the L-shaped support 501 can achieve the limiting of the critical position, that is, when the vertical plate of the L-shaped support 501 contacts the platform component 1, it is the maximum telescopic position, avoiding over-adjustment, and at the same time it can also achieve the support of the fixture bottom plate 3.

[0061] Among them, simply using the abutting surface of the horizontal plate to contact the fixture bottom plate 3 will cause large friction, which makes it inconvenient for the fixture bottom plate 3 to move toward the import and export ports. Therefore, in order to reduce friction and achieve position limiting, the following improvements are made:

[0062] The clamp support member 5 includes a connecting plate 500 parallel to the straight line, and a plurality of L-shaped supports 501 distributed in a straight line are provided on the connecting plate 500;

[0063] One side of the vertical plate of the L-shaped support 501 in the thickness direction is connected to the connecting plate 500, and the other side of the vertical plate in the thickness direction is the platform abutment portion; the top of the horizontal plate of the L-shaped support 501 is rotatably provided with a roller bearing 502, and the circumference of the roller bearing 502 is used to contact the side of the fixture bottom plate 3. The provision of the roller bearing 502 greatly reduces the friction force, making it easier to move the fixture bottom plate 3.

[0064] In some preferred embodiments, before using the fixture switching import and export centering platform, the platform assembly 1 needs to be fixed at the position corresponding to the import and export port of the fixture switching mechanism 9. When the sizes of the import and export ports are different, or when it is necessary to set corresponding to other fixture switching mechanisms 9, the platform assembly 1 needs to be easy to install and transport, so the following settings are provided:

[0065] refer to Figure 3 The platform assembly 1 includes a first support structure 100 and a second support structure 101 which are spaced apart; the tops of the first support structure 100 and the second support structure 101 are both provided with a rectangular mounting surface for mounting the support assembly 2;

[0066] The fixture switching import / export centering platform also includes a transfer trolley or an auxiliary support frame 8 located between the first support structure 100 and the second support structure 101 .

[0067] The transfer trolley or auxiliary support frame 8 plays a supporting role, dividing the platform assembly 1 into three main parts, thereby facilitating disassembly and assembly, facilitating transportation, and being adaptable to different clamp switching mechanisms 9, thereby increasing its versatility.

[0068] Furthermore, a telescopic assembly 4 is respectively provided on the first support structure 100 and the second support structure 101;

[0069] The telescopic assembly 4 includes a plurality of mounting horizontal plates 400 spaced apart along the length direction of the rectangular mounting surface; a telescopic cylinder 401 is provided on the top of each mounting horizontal plate 400, and the extension line of the output shaft of the telescopic cylinder 401 is perpendicular to the straight line and connected to the clamp support member 5 through a transition plate 402;

[0070] The control assembly 7 includes an air pump, a controller, a solenoid valve group and air pipe fittings. The air pump is connected to the telescopic cylinder 401 through the solenoid valve group and the air pipe fittings, and the controller is signal-connected to the air pump and the solenoid valve group.

[0071] The first support structure 100 includes a cross beam 102; a bearing plate 103 is provided on the top of the cross beam 102, and a plurality of vertical legs 104 are provided on the bottom along the length direction thereof; a ground connection seat 105 is provided on the bottom of the vertical legs 104; the installation cross plate 400 is connected to the cross beam 102 by bolts. A reinforcing diagonal brace 106 is provided between the vertical legs 104 and the cross beam 102; two vertical clamping plates 107 are provided on the top of the vertical legs 104; a mounting groove is formed between the two vertical clamping plates 107, and the vertical clamping plates 107 are connected to the cross beam 102 by bolts.

[0072] The above structure shows that the first support structure 100 and the second support structure 101 have the same structure and a simple composition structure. Multiple vertical legs 104 evenly share the force, and the ground connection seat 105 is convenient for connection with the ground. In addition, the strengthening diagonal support rod 106 makes its strength increased and the structure stable.

[0073] Principles of this application:

[0074] (1) The following steps are required for use:

[0075] The first step is to place the platform assembly 1 at the import and export port position of the fixture switching mechanism 9 so that the central axis of the platform assembly 1 is coaxial with the central axis of the import and export port; then connect and fix the bottom of the platform assembly 1 to the ground or the bottom of the fixture switching mechanism 9 by screws or other fixings.

[0076] In the second step, the fixture base plate 3 of the device to be replaced is placed on the support assembly 2 and moved; then the control assembly 7 adjusts the fixture abutment 5 to abut against the fixture base plate 3 through the telescopic assembly 4 to determine the size of the fixture centering channel 6, and at the same time, the fixture base plate 3 moves in the fixture centering channel 6; this state refers to Figure 4 As shown, the center axis a of the fixture base plate 3 does not coincide with the center axis b of the platform assembly 1 .

[0077] In the third step, during the movement, the control component 7 adjusts the clamp support 5 again through the telescopic component 4, thereby moving the clamp base plate 3 and the clamp centering channel 6, so that the clamp base plate 3 is coaxially aligned and enters the introduction and export port of the clamp switching mechanism 9. The above whole process is adjusted and aligned during movement, which is easy to operate and does not require repeated adjustment using a sling or forklift, and the clamp replacement efficiency is high. The final state after adjustment is as follows Figure 5 and Figure 6 As shown, the center axis a of the fixture base plate 3 coincides with the center axis b of the platform assembly 1 .

[0078] (2) The laser distance sensor can be used to know whether the clamp abutment 5 is in contact with the clamp bottom plate 3, and determine the size of the clamp centering channel 6; after the contact, the telescopic length detection unit is used to detect the telescopic length of the telescopic component 4; the control component 7 makes judgments and analyses based on the telescopic lengths of the two telescopic components 4;

[0079] Since the installation position of the platform component 1 is relatively aligned with the quasi-clamp switching mechanism 9, when the clamp base plate 3 is aligned with the import and export ports, the telescopic lengths of the telescopic components 4 on both sides should be equal and equal to the set telescopic length; therefore, when the telescopic length of the telescopic component 4 reaches the set telescopic length and the telescopic lengths of the two telescopic components 4 are equal, the locking is stopped and the adjustment is completed. Subsequently, only the clamp base plate 3 needs to be moved. The above settings achieve real-time and precise adjustment and alignment.
